Why do you get worse?
People always say that "bitter summer" refers to the hot weather, fatigue and fatigue, weakness, and appetite to worse.
In fact, it is not just a high -temperature day. The human body has no appetite during fever or after severe exercise.
The main reasons for this phenomenon are the following:
Reduced digestive juice
In high temperature environments, the activity of the sympathetic nerve and adrenal glandular system is enhanced, the gastrointestinal tract is in a relatively ischemia, and the digestive glandular function is reduced, which reduces the secretion of saliva, gastric juice, pancreas, bile, and intestinal fluid.
Central nervous regulation
The central nervous system also affects appetite.When the body temperature rises, the nerve conduction is passed to the temperature regulating center of the body temperature, and the body temperature regulation center has a inhibitory effect on the centered center, thereby reducing the amount of eating.
The body "blocks" calories
Human intake of food has a great impact on body temperature.Food will generate heat, and the human basic metabolic rate is low after the weather is hot, and the calories need less. In this case, the human body often avoids increased body temperature and appetite will decrease.
Emotional is more irritable
In psychology, there is a term called "Meteorological Emotional Effect", which means that human emotional state will be affected by the weather.The discomfort caused by continuous high temperatures makes many people feel more irritable. In severe cases, they even "emotional heatstroke". This emotion will also affect appetite.
Five diseases can also affect appetite
Excluding high temperature and emotional factors, if there is no special change in the living environment and poor appetite in a short time, we must be alert to whether these diseases are affecting appetite.
Chronic gastritis, gastrointestinal ulcers, decreased gastric secretion function, and disorders of digestive system dysfunction can cause loss of appetite.
Liver and gallbladium and pancreatic disease
Acute hepatitis, chronic hepatitis, liver cirrhosis, liver cancer, cholecystitis, cholelinia, pancreatitis and other liver and gallbladder diseases may cause indigestion and symptoms of anorexia.
Patients with pancreatic tumors are very concealed, and their manifestations are often inexplicable decreased appetite and weight loss.
Mental and mental illness
Once the brain is controlled, the stress of life and work, and poor sleep, will affect appetite.
Neurological anorexia, depression, mental trauma, and emotional appetite loss can make people appetite without appetite.
Lack of trace elements
Trace elements can ensure the normal secretion of digestive enzymes such as gastricase, lipase, and amylase in the human digestive system.The lack of trace elements in the human body can lead to loss of appetite. For example, when zinc deficiency, taste buds will decrease, resulting in loss of appetite, and iron deficiency anemia can also affect appetite.
When the heart function is insufficient, insufficient blood supply to the gastrointestinal tract will lead to a decrease in digestion; blood vessels in the gastrointestinal tract can also suppress appetite.
Severe coronary heart disease leads to heart failure, lung heart disease, and partial symptoms that are not typical of myocardial infarction. Sometimes the only discomfort that occurs is decreased appetite.
In addition, if there is no appetite, and when the hands and feet are weak, vomiting, etc., the family should highly suspect cerebral vascular disease and seek medical treatment in time.
It should be reminded that the decreased appetite or weight loss for unknown reason is one of the important symptoms of certain malignant tumors. Sometimes it is the first symptom of some tumors. Moreover, most cancer patients are in advanced.Primary liver cancer.
