Why is there no appetite in an adult. Lost appetite: what to do next, causes

To the question: "No appetite, the reasons for an adult?" there are many answers.

Nutrient deficiencies are a must affect not only well-being, but also health. Therefore, it is necessary to solve the problem of their absence as soon as possible. How to increase appetite and why did it disappear?

The difference between hunger and appetite

Before diagnosing loss of appetite, you should understand this concept. Appetite is often confused with hunger, a reflex that occurs when there is no food.

The mechanism for the development of hunger is triggered by a decrease in glucose levels, due to which a signal is sent to the centers of the brain. At the time of the onset of a hungry spasm, a person has active salivation, the sense of smell improves and a pulling sensation “in the pit of the stomach” appears.

All these symptoms help a person feel hungry and go in search of food. At the same time, he has no desire to eat certain foods, he is ready to eat any dish.

The manifestation of a feeling of hunger, in which a person desires certain products is called appetite. This feeling is influenced by many factors: time of day, country of residence, taste preferences, emotional state.

Violation of habitual taste needs, when a person does not want food at all, is called a decrease in appetite. This condition leads to anorexia and other problems.

Associated symptoms

The brain signals that the body needs to eat. It contains neurons that carry a signal to the digestive organs.

In the body of an individual experiencing a feeling of hunger, increased insulin levels and there is an active production of gastric juice. The absence of hungry urges indicates that the brain is working on other needs. Reduced appetite - protection against certain diseases of the digestive system.

There are symptoms that often accompany a person in the absence of appetite. Nausea, weakness - the most famous of them. Thanks to these signs, it is easier for doctors to determine the cause of the loss of appetite.

Causes of loss of appetite

All the reasons due to which appetite disappears can be divided into two categories: pathological and non-pathological.

Pathological causes

Most often, poor appetite in adults indicates a disease.

To forget about problems with appetite, you need professional help.

Pathological causes of decreased appetite include:

Intestinal dysbacteriosis. Beneficial and pathogenic microorganisms take part in the processes of digestion. If their balance is disturbed, the body does not receive the necessary trace elements from food.
endocrine problems. Lack of hormones leads to nausea and vomiting. As a result, the person becomes weak and loses his appetite.
Chronic diseases of the gastrointestinal tract. Similar symptoms indicate a stomach ulcer, gastritis,. At the first signs of an exacerbation of the disease, preventive treatment should be taken.
Mental problems, neuroses. High workload, stress, lack of rest and moral support lead to apathy, depression. These problems are often accompanied by weakness, nausea, fatigue, and lack of appetite.
body intoxication. harmful bacteria can provoke intoxication, as a result of which a person will feel weakness and aversion to food.
Cardiovascular diseases. The deterioration of blood vessels provokes a general weakness of the body, and high blood pressure causes nausea.
Drug addiction. The need for constant medication gastrointestinal tract work hard. Because of this, gastritis, an ulcer, and pathology of the pancreas may appear.
Oncology. During the period of chemotherapy, a failure occurs in many processes, especially in the work of the digestive organs.
Viruses and infections in the body. With illness, there is often a significant decrease in appetite, as forces are directed to the fight against viruses. To a large number of toxins did not lead to weakness and nausea, you should maintain water balance, namely drink plenty of fluids.

Non-pathological causes

Natural causes cause a situation in which a person refuses to eat.

They do not depend on any disease, as they arise due to external pathogenic factors.

Distinctive features of non-pathological causes:

the duration of the symptoms does not exceed 4-5 days, then the increase in appetite occurs independently;
need not health care, medication;
absent Negative influence on health;
symptoms recur no more than once a month;
loss of appetite does not lead to sudden weight loss.

The list of non-pathological causes includes the following conditions:

Menstruation. In this period female body especially influenced by hormones. A sharp increase in the level of estrogen and progesterone provokes weakness, loss of appetite. At the end of the cycle, abdominal cramps and headaches are often added to these symptoms.
Binge eating. Lack of proper nutrition during the day leads to an increase in appetite at night. The organs of the gastrointestinal tract were not subjected to stress all day, therefore, in the evening, when preparing the body for sleep, the food consumed can cause poor sleep, nausea and vomiting. All this will lead to a decrease in appetite.
Prolonged fasting. If a person voluntarily refuses to eat, it can cause nausea and weakness. Since in long time food does not get in, the secret produced negatively affects the mucous membrane, irritating it. In the absence of food, working capacity decreases and weakness and loss of strength appear.

Diagnosis of poor appetite

Normal life is ensured by balance, which is the alternation of hunger and appetite. Violation of the normal state for any reason leads to a decrease in appetite, and then a feeling of hunger.

Eating high-calorie foods can increase the time between the desire to eat up to 4-5 hours.

However, if hunger does not come for more than 8 hours, this is a signal that problems have appeared in the body.

A decrease in blood glucose levels will cause dizziness, weakness, loss of strength.

To diagnose the cause that caused the loss of appetite, you should consult a doctor. He will appoint full examination body, including testing. If a woman has a problem with appetite, pregnancy should be excluded first.

What can increase your appetite

The causes that provoked a decrease in appetite and were identified during the diagnosis are eliminated by therapeutic methods. Parallel doctors advise the patient to adhere to the following recommendations:

Follow a meal schedule. You need to eat several times a day in small portions. Dinner should be no later than three hours before bedtime. Eating daily at a certain time will contribute to the production of saliva, prepare the body for the absorption of food.
Food should be chewed slowly, without being distracted by extraneous stimuli (TV, computer). You should apply an attractive serving, work on a beautiful design of dishes.
Food should be tasty and varied.
When fighting poor appetite, it is very important to observe the daily routine: sleep for at least eight hours, do not forget about rest. Mild physical activity is encouraged, as sport stimulates the urge to eat.
Stress should be avoided conflict situations, bad emotions.
In order for the digestive juice to be produced more actively, you need to eat foods that stimulate this process, for example, pickled and salty dishes. Spices, spicy seasonings, herbs, sour berries, foods high in vitamins B and C, decoctions and infusions of bitter herbs contribute to an increase in appetite.

Loss of appetite in old age

Lack of need for food and persistent loss of appetite may occur in the elderly. Retirees often limit themselves to healthy and nutritious food due to financial problems. In addition, it weakens with age, or diarrhea begins, the work of receptors worsens. The body begins to digest food poorly.

The above factors affect appetite. To avoid problems with the work of the gastrointestinal tract, you need to increase the number of easily digestible foods. The menu should include vegetable stew, cereals, fish, lean meats. Older people should avoid fatty and fried foods, not eat large portions and, if necessary, use a blender to grind food.

How to increase your child's appetite

Adults often have a problem feeding the baby because of his refusal to eat. To increase your child's appetite, you can take the following steps:

make a diet that is optimally suited to the age and characteristics of the child;
follow the diet;
spend several hours a day outdoors;
include outdoor games and sports in the daily routine;
attractively decorate children's dishes;
add fruits and dried fruits to cereals;
do not force-feed the child;
do not overfeed the baby;
reduce the number of snacks on cookies and other floury dishes;
place small portions on a plate.

If the lack of appetite lasts for several days, you should not independently look for the cause and carry out treatment. The specialist will quickly determine what the decrease in appetite is due to and prescribe medications to enhance it.

Mankind throughout its history treats food with such trepidation that a sudden loss of appetite is perceived by us as alarm symptom. And not in vain. There are many disease states in which the loss of interest in food is one of the early signs diseases. However, sometimes a decrease in appetite is a variant of the norm - unless of course it lasts too long. MedAboutMe found out under what conditions and diseases a person stops wanting to eat.

This is the most innocuous of the conditions in which there is a deterioration in appetite. Most often this happens in the first trimester, when most expectant mothers suffer from manifestations of toxicosis - nausea and vomiting. Some women cannot eat only in the morning, while others do not feel well all day. Doctors recommend in such cases to switch to soups and liquid milk porridge so that the body receives the calories it needs.

And loss of appetite during pregnancy is observed against the background of deficiency folic acid. This vitamin (B9) is also necessary for the normal development of the fetus, so loss of appetite in this case can be perceived as an alarm signal.

Decreased appetite can also indicate an iron deficiency or develop against a background of advanced level the hormone progesterone, which blocks the feeling of hunger.

As the fetus develops, the pressure on the internal organs women. In the second trimester, the pressure of the growing uterus begins to be felt by the intestines. As a result, constipation, a general deterioration in digestion - and a decrease in appetite can be observed. And in the third trimester, the uterus already presses on the stomach, which also does not add to the desire to eat an extra piece.

However, all these nuances are very individual. Someone forces himself to eat, and someone, on the contrary, eats with appetite "for two" to the delight of those who empathize with others.

2. Stress is a moment to fight, not to eat.

When the body is under stress, there is a powerful release of the hormone adrenaline, which makes the heart beat faster, but at the same time slows down digestion. Stress is a time to fight, not to stuff your stomach!

But we lose our appetite when it comes to strong short-term stress, when we need to immediately and very quickly run away or fight. And if the stress is moderate, and even prolonged, for example, the boss reprimanded at work, the child brought a deuce at home, and even quarreled with her husband, then the hormone cortisol is produced in the body, which, on the contrary, whets the appetite, especially in relation to high-calorie foods. As a result, a person begins to nervously absorb everything that comes to hand.

Many drugs as side effect lead to a decrease in appetite. Among the most common are antibiotics, muscle relaxants, drugs for the treatment of fungal diseases, anti-rhinitis containing phenylpropanolamine, etc. Antidepressants, antihypertensive drugs (to combat high blood pressure), non-steroidal anti-inflammatory drugs (NSAIDs), drugs prescribed for chronic obstructive pulmonary disease, Parkinson's disease and migraine.

This means that when discussing the causes of loss of appetite with your doctor, you should mention all medications and dietary supplements that are this moment the person takes. Perhaps it's about them.

4. Colds and flu

When viruses causing acute respiratory diseases, penetrate into the human body, it is activated the immune system. This leads to increased production of cytokines - proteins that reduce appetite and cause a feeling of fatigue. Scientists believe that in this way the body makes a person save energy to fight the disease. The maximum that a tired body can do is eat a bowl of chicken broth, and then fall asleep in anticipation of recovery.

Hypothyroidism, i.e. deficiency of hormones thyroid gland- very strange state in regards to appetite. Paradox: a person does not want to eat, literally “starves”, but at the same time slowly but surely gains weight. This is due to the fact that the metabolism against the background of hormonal imbalance is disturbed, and water is retained in the body and edema develops. In addition, with hypothyroidism, a person's activity is reduced, calorie consumption is minimal. This means that when you try to eat normally, weight gain will occur.

6. Anemia

This condition is also called anemia because iron deficiency anemia there is a decrease in the number of red blood cells or a drop in hemoglobin levels below normal. Decreased appetite is one of the early signs of anemia. Often this condition develops in infants and the elderly. Moreover, the latter have loss of appetite for initial stages disease leads to a progressive lack of iron and vitamins, weight loss and the development of severe disorders of the nervous and other body systems.

Nausea, vomiting and complete absence loss of appetite are often symptoms of migraine - severe headaches. Much less often, in patients with migraine, the appetite, on the contrary, increases.

Another cause of headaches and loss of appetite is traumatic brain injury (TBI). A person with a mild form of TBI suffers from dizziness, nausea, up to vomiting, sometimes a temporary loss of smell develops - it is not surprising that he is not interested in food and may even cause a feeling of disgust. It should be noted that often with a mild form of TBI, other symptoms are very mild. So if a child falls, and then complains of dizziness and refuses to eat, this is a reason to see a doctor for an examination for TBI.

8. Depression

A mental disorder in which the human body actively produces the hormone corticoliberin (aka corticotropin-releasing hormone, CRH). This substance is involved in the regulation of many mental functions. In particular, it causes a person to experience fear, anxiety, suffer from sleep disorders, and also leads to loss of appetite. In addition, with depression, constipation often develops, which lasts for 4-5 days, which also does not contribute to the desire to eat.

There are, of course, atypical forms of depression, in which a person's appetite, on the contrary, increases abnormally, but they are much less common.

Finally, every third person in old age worsens appetite. This is a variant of the norm. Loss of appetite is due to the fact that aging slows down many processes in the body, including digestion, so a person feels full longer. Often the taste and smell change, the food even begins to look different - less attractive. Don't Forget About What Changes hormonal background(especially in women). Many older people take medication - and we talked above about drugs for hypertensive patients, etc.

If a person, regardless of age, is sick with ARVI, do not force-feed him. Refusal to eat is normal and will pass as you recover. But drinking should be available all the time - dehydration should not be allowed.
If a prolonged loss of appetite occurs during pregnancy, you should discuss this point with your obstetrician-gynecologist. Perhaps the body is missing something.
If loss of appetite is combined with chronic fatigue, drowsiness, swelling of the face, you should contact an endocrinologist and get tested for thyroid hormones.
In general, in general, an unexplained loss of appetite for a long time is a reason to see a doctor. You should not explain to yourself that this organism is so conscious and independently decided to lose weight. The decision to fight excess weight is made by the person himself and, as a rule, he has to make a lot of efforts to force himself to realize them. Alive and healthy body does not refuse food.

Food must be taken in sufficient quantities. Food is strength, health, mind, endurance. By skipping meals, we deprive the body of those substances that it needs so much. Where else to take strength, except from food? Unfortunately, man has not yet learned (and is unlikely to ever learn) to draw energy from sunlight for your body.

The reasons for which may be different - the problem is very common. In some cases, a person seems to understand that he will feel bad without food, but he cannot force himself to eat. This is not about any mental disorders (for example, anorexia), but about the state when there is no urge to eat.

In adults and children, it can appear completely unexpectedly. In some cases, the cause is not always easy to determine. What to do if the reason is clear? You just need to remove it, and everything will return to normal.

Lack of appetite: causes

Problems with eating can arise due to some kind of disease. It's not just about indigestion or any other digestive organs - a common cold can lead to loss of appetite. When sick, a person cannot eat, but in order to recover, he needs to eat normally. So it turns out that in such a situation it is necessary even through force.

Loss of appetite, the causes of which we are considering, can be caused by severe stress. This is quite understandable, since severe stress affects the state of the whole organism. Also, the causes include mental disorders like depression and apathy. They are directly related to the fact that a person loses the desire to live, move and seeks to move away from the outside world in every possible way. The mood in such cases is always bad. Refusal of food can last for a very long time, and the consequences will be that you will lose weight and weaken. Without healthy food, it is very difficult to beat a mental disorder.

Loss of appetite, the causes of which are not always easy to determine, often occurs in people who move very little. Try to work physically - you will instantly want to eat, and very much. Moving, a person burns a large amount of energy, which, in turn, receives from food. Hunger is a signal that it's time to eat. What can a person who sits at home all day long expect? Yes, problems with appetite are guaranteed to him.

Periodically, the appetite disappears in pregnant women. This is quite normal and there is nothing abnormal in it.

Loss of appetite caused by stress can only be cured with rest. Take a vacation and go somewhere where you really feel good. It is important to unwind and move away from the gray everyday life as much as possible. The same can be recommended for depression. New experiences will help you fall in love with life again and restore your appetite.

It is recommended to take vitamins and mineral complexes. Force yourself to eat fruit, meat, fish. Be sure to drink milk - it's really a wonderful product. Healthy food, consumed even through force, will help you quickly return to normal.
If there is a suspicion of any disease, be sure to go to the doctor and do all the necessary tests. Remember that health issues are very important. Give them maximum attention, and no ailments will cause you trouble.

In order to make up for the lack of all trace elements in the body, a person must eat properly and rationally. In the event that there is no appetite, and the food itself causes rejection and a lot of other discomfort means the person needs help. Lack of appetite can be caused by many reasons, including not only diseases and pathologies of the gastrointestinal tract. Few people know, but nervous ground this can happen too. In what situations lack of appetite is accompanied by nausea and weakness, we will find out further.

In order to understand what to look for the reason, specifics should be taken into account. all present symptoms:

Lack of appetite - the fact that a person would not hurt to eat is signaled by the brain, the neural endings of which send a signal to the digestive organs, forcing a person to think about food. As a result, gradually developed gastric juice and increases the level of insulin in the blood. If there is no appetite, then the brain is busy with completely different, more important things at the moment. It can also be reinforced by diseases of the digestive tract, as a result of the progression of which, lack of appetite occurs as a natural defensive reaction.
Nausea - this process is also quite physiological, it is necessary in order to release the contents of the stomach in critical situations. This sign is extremely important in diagnosis, because in combination with other symptoms it allows a more accurate diagnosis.
Weakness is a state known to everyone, especially those people who are forced to work hard and hard. A person with special difficulty manages to perform the usual actions, while feeling an increased load and fatigue.

Nausea, weakness and lack of appetite, perhaps the most common symptoms that both adults and children are familiar with. What prerequisites can influence the emergence of such a clinical picture?

Causes

If you organize everything possible reasons that can cause weakness with nausea and a complete lack of appetite, then they can be conditionally divided into two large groups: pathological and non-pathological.

Non-pathological causes

These reasons unrelated to disease. They arise if external pathogenic factors exert their influence on the body, or they occur as a natural process. Their main feature is as follows:

symptoms last no more than 4-5 days, after which they disappear on their own;
do not require medical attention and medication;
do not have life-threatening side effects on the body;
may be repeated, but not more than once a month;
don't cause acute loss weight.

Menstruation and premenstrual syndrome - in the course of hormonal adjustment and preparation for fertilization, a woman's body is literally subject to the actions of hormones. Sharp jumps in progesterone and estrogen, to which the body adapts gradually, can provoke nausea, weakness, and loss of appetite. When the cycle ends and a new one begins, a woman may also experience headaches and abdominal cramps, which is a completely natural process that does not require intervention.
Overeating, especially at night - when during the day a person did not have the opportunity to fully eat, and meals were reduced to a maximum of fast food, then when you come home, where a delicious dinner is waiting, it is difficult to control yourself. As a result, the digestive tract organs did not have a load all day, and in the evening, when, in fact, the body and all its systems are preparing for sleep and slowing down their life support processes, the food eaten can cause bad sleep. Eating a heavy meal before bed leads to nausea, which indicates the inability of the pancreas to produce the right amount of enzymes. The symptoms are especially acute in the morning, when nausea can continue with vomiting, which will lead to weakness and lack of appetite.
Prolonged fasting is an unauthorized refusal of food, allegedly in order to lose extra pounds may cause nausea and weakness. The fact is that if in the stomach long time food does not come in, the secret produced adversely affects the mucous membranes, causing irritation. Sometimes nausea occurs immediately after a person experiences a strong feeling of hunger. Lack of food reduces performance, and also provokes weakness.
Syndrome chronic fatigue- observed in people who constantly experience fatigue and loss of strength. This condition is typical for people who work seven days a week, and the number of hours of work is greater than rest. Workaholism is commendable, but it affects health. Lack of adequate sleep affects nervous system and the brain, which can give incorrect commands to the entire body.

These reasons are most common in Everyday life, because the modern rhythm of life makes it impossible to eat well and have a normal rest.

Pathological causes

Associated with the presence of a disease in the body. In most cases, medical attention is required to eliminate. This group includes the following reasons:

Dysbacteriosis is an intestinal disease in which the balance of beneficial and pathogenic microorganisms involved in the digestive process is disturbed. Poor digestion has a detrimental effect on the entire body, since it is not possible to get everything from food. nutrients with which she is rich.
Endocrine diseases - hormonal imbalance and lack of production of certain hormones can provoke nausea, sometimes vomiting, followed by weakness and lack of appetite.
Chronic diseases of the digestive system, which have become aggravated - most often such symptoms are inherent in gastritis, stomach ulcers and duodenum and gastroduodenitis. Nausea, weakness and lack of appetite are the first signs that old diseases require attention and timely preventive treatment.
Mental disorders - if a person constantly experiences increased emotional stress and stress, while there is no rest and support from loved ones, depression may occur. This psycho-emotional state implies indifference to everything that happens around, and is also accompanied by a lack of appetite, nausea and general weakness.
Intoxication - if pathogenic microorganisms are active in the body, this provokes intoxication. Especially often, such processes occur in the stomach and intestines, when, getting from outside, bacteria begin to actively “get used” to the body and take everything that is available from it. In this case, nausea and loss of appetite are primary signs indicating the presence of pathogenic microflora.
Cardiovascular disease - similar symptoms are familiar to people suffering from chronic arterial hypertension when the pressure in the body is high. Nausea in this case can manifest itself even after eating, and weakness is dictated by the deterioration of blood vessels.
Drug dependence - if a person voluntarily or out of necessity constantly takes medications, the gastrointestinal tract receives an enormous load, digesting and assimilating chemical compounds. As a result, nausea and lack of appetite may indicate the presence of gastritis and peptic ulcer and pathologies of the pancreas.
Availability oncological diseases- when a person has cancer (no matter what organ), and chemotherapy is carried out, all processes in the body go astray, including digestion. Appetite decreases, against which fatigue and drowsiness appear. Nausea and vomiting may occur, especially after taking chemotherapeutic agents.
The presence of an infection or virus in the body - many will think about why, when you are sick, you don’t feel like eating at all. The answer is very simple. The fact is that at the time of active production of leukocyte cells, the body concentrates all its forces precisely on this process, allowing the patient to recover as soon as possible. Lack of appetite in this case is a justified measure. An excessive amount of toxins can provoke nausea and weakness, which can only be eliminated by maintaining sufficient water balance.

Also, a decrease and complete lack of appetite, weakness and nausea, inherent in the following categories of the population:

Drug addicts - long-term use narcotic drugs gradually reduces the sensitivity of the brain and nerve cells, which leads to social degradation. At the same time, all the processes occurring in the brain are aimed at only one thing: the search for a dose at any cost.
People who smoke - nicotine kills microscopic cells in the stomach. Hence, the process of splitting food is somewhat complicated. Plus, rich in resin tobacco smoke, can influence circulatory system causing anemia.
Alcoholism - the abuse of alcoholic beverages, which is carried out systematically, leads to disruption of the digestive processes, and also has a devastating effect on the cells of the pancreas and liver.
Toxicosis of pregnant women - manifests itself as a protective reaction of the body. At the beginning of pregnancy, the hormonal background is rearranged in such a way that all conditions are favorable for the development of the fetus, although the body itself tries in every possible way to reject the fetus, perceiving it as a foreign substance.

TOP 5 reasons

Among the most rare diseases that speak of their existence, by provoking nausea, lack of appetite and weakness, there are:

Diabetes mellitus - is determined by a metabolic disorder in the body, as well as the absorption of glucose. A person for quite a long time may not suspect that he has problems with the pancreas and the hormonal system. Pathology can develop over years and decades, until it takes an acute form with more dangerous symptoms.
Neurosis is a disorder of mental balance in which a person, under the influence of external stimuli, leaves the comfort zone. Nausea in neurosis appears exactly after the appetite disappears. It is logical to assume that if food does not enter the body, then there is no energy, and as a result, weakness appears.
Pathologies of the thyroid gland - a sufficiently small size of this gland can cause big problems for health when its activity becomes uncontrollable. Lack or excess of thyroid hormones provoke various pathologies and diseases that are difficult to correct and treat.
Oncology - in 95% of all cases of cancer diagnosis falls on a random examination. A person may not be aware of his problem, and the usual morning sickness, lack of appetite and weakness will be attributed to increased fatigue at work.
Anorexia is a disease associated with mental disorder, is the most life-threatening. Long-term refusal of food plays a cruel joke on a person, subsequently provoking a complete disgust for any food, even if it previously caused complete delight. Sudden weight loss always accompanies dizziness and insomnia. Absolutely all processes in the body are disrupted, so all available forces are aimed at maintaining vital processes.

When is medical help needed?

Only 3% of all patients who report persistent nausea, weakness and loss of appetite seek medical help. The majority of conscientious patients are ready to give thousands for a “pills for all diseases” recommended by a kind aunt from a pharmacy.

Consider a number of situations where medical assistance really badly needed:

Nausea does not go away for more than 5 days, increases after waking up and ends with vomiting.
Apart from common symptoms more specific manifestations appear: pain in the abdomen, throat, back.
The body temperature rises and is not knocked down by any medications.
There is an acute onset of pain.
There are bleeding.

In these cases, it makes no sense to try to help a person on your own. Self-medication is not only inappropriate, but can also cause complications. Most right choice This is a consultation with a doctor and a complete medical examination.

What actions can be taken?

If the appeared nausea, lack of appetite and weakness can be compared with the prerequisites (overeating, poisoning, PMS), and the general condition of the patient does not cause concern, you can take actions such as:

Drink plenty of pure mineral water.
