Feeling flustered and shaking when you are hungry? Doctor: It may be related to these diseases, don't take it seriously!

Why do people feel hungry?

　　A related research survey has shown that the stomach secretes a substance called ghrelin, which is the only peptide known to promote appetite. When there is no food for a long time, this hormone will be secreted in large quantities. And act on the hunger central system, making you feel like you want to eat and feel hungry.

　　Hunger is a normal physiological manifestation of the human body, and it is often unbearable, especially for people with poor self-control, who will consciously ingest food. In life, when some people are hungry, they will not only feel uncomfortable in the stomach, but also have symptoms such as palpitations, tremors, and restlessness . At this time, we should be vigilant. It is not only a simple hunger, but it may also be a signal that the disease has found itself.

　　For example, the occurrence of the following diseases will cause symptoms such as palpitation and tremors when hungry:

　　1. Hyperthyroidism

　　Hyperthyroidism is clinically referred to as hyperthyroidism , which refers to the fact that the normally secreted thyroid gland secretes a large amount of thyroid hormones under the influence of the disease. The original function of this hormone is to promote metabolism and promote the body's redox reaction .

　　Therefore, in the case of increased secretion, the patient will fall into a state of hypermetabolism, increased gastrointestinal activity , prone to hunger, and a significant increase in food intake compared to before. At the same time, thyroid hormone also stimulates sympathetic nerve excitation , so patients will also experience palpitations, manual, anxiety, insomnia and other problems;

2. Low blood sugar

　　Hypoglycemia refers to the adult plasma glucose lower than 2.8mmol/L (50mg/dl), which is caused by various factors, such as diabetes, long-term malnutrition, excessive dieting and so on.

　　After hypoglycemia, patients often have symptoms of sympathetic nervous excitation, such as strong hunger, accompanied by pale complexion, profuse sweating, tremors of limbs, palpitations and other symptoms, which are all common manifestations.

　　In the case of severe hypoglycemia, patients may even have serious problems such as mental disorders, disturbance of consciousness, personality changes, and coma ;

　　3. Diabetes

　　The appearance of the disease is related to the damage of islet function and insulin resistance, that is, the patient's body cannot use glucose function, which leads to the normal concentration in the blood exceeding the standard, which in turn causes diabetes with hyperglycemia as the main symptom.

　　Because of this, due to the reduced , although the blood sugar is at a high level , the glucose concentration difference in the arterial and venous blood is very small , and the tissue cells are still in a state of starvation, which will affect the feeding center. Causes irritation, causing hunger to appear.

　　If the patient does not eat in time, there will also be symptoms such as palpitation, shortness of breath, profuse sweating, and restlessness . After eating, these symptoms will be significantly relieved;

　　4. Stomach ulcer

　　The so-called gastric ulcer refers to the ulcer that appears in the corners of the stomach, antrum, cardia and other regions . It is one of the digestive tract ulcers and one of the most common digestive tract diseases.

　　According to the current clinical data, hunger pain is the main symptom of gastric ulcer . The patient may experience dull, dull, distending or burning pain in the left upper abdomen, sternum and posterior xiphoid process, which will be relieved after eating .

　　Chronic stomach disease for a long time can lead to problems such as indigestion and nutritional deficiencies. When the body lacks nutrients , symptoms such as tremors and palpitations may occur.

　　All in all, if you only feel obvious hunger when the meal time is coming, this is a normal physiological response in most cases, and you do not need to be overly vigilant.

　　However, if you have frequent hunger pangs recently, and are prone to symptoms such as palpitation, anxiety, and sweating, this may be a sign that the disease has found you. You should be vigilant and seek medical attention in time.
