(1) malnutrition. Adults and children are prone to this disease, but children, especially young children, are more prone to this "emaciation" disease, which is called "malnutrition" by Chinese medicine.

(2) Intestinal parasitic diseases. Common diseases include roundworm, hookworm, pinworm and so on. Ascariasis is more common. This kind of parasitic diseases, due to the parasitism of a large number of eggs, will "grab" nutrition with people for a long time, which will lead to sallow and emaciated, malnutrition, anemia and dysplasia, thus losing weight.

(3) Hepatitis, liver cirrhosis and liver cancer. These liver diseases often have symptoms such as general weakness, loss of appetite, liver pain, diarrhea, low fever, weight loss, etc., which makes them thinner and thinner.

(4) diabetes. There are many reasons for weight loss caused by this disease. The main reason is the high blood sugar concentration of diabetic patients. After being filtered by the kidneys, it can't be completely absorbed into the blood like a healthy person, and a large amount of glucose is excreted from the urine, so the body has to use the stored fat and protein to make up for the lack of energy, which leads to body weight loss.

(5) Chronic heart failure. Such patients can cause physiological dysfunction, especially right heart failure, which can lead to blood stasis in limbs and gastrointestinal tract, causing indigestion, loss of appetite, nausea and vomiting. To lose weight.

(6) Chronic uremia. As a result of renal failure, the physiological function of human body will be seriously disordered, and diseases of digestive system, cardiovascular system, nervous system, hematopoietic system and respiratory system will appear. Will the sharp decline in digestive function not lead to weight loss?

(7) hyperthyroidism. Due to high metabolism and high excitement of nervous system, patients often eat more, are hungry, are afraid of heat, are afraid of sweat, and their heart beats faster. Among them, the more prominent patients have increased their appetite after illness, but their weight has decreased, showing progressive emaciation.

(8) Peptic ulcer. Most of these patients have a long history of epigastric pain, acid regurgitation and belching. Some patients are afraid to eat because of loss of appetite or fear of stomachache, which leads to weight loss and emaciation.

(9) Crohn's disease, also known as localized enteritis. This is a chronic intestinal inflammation with unknown etiology, which is characterized by abdominal pain, diarrhea, loss of appetite, nausea, vomiting, fever and anemia. Because of eating less, intestinal malabsorption, energy consumption increased, so the weight gradually decreased, thus wasting away.

(10) Tuberculosis. It is a chronic infectious disease caused by mycobacterium tuberculosis, such as tuberculosis, intestinal tuberculosis, liver tuberculosis and bone tuberculosis. Once patients with pulmonary tuberculosis have symptoms of poisoning, their metabolism will be accelerated and nutrition will be consumed. In addition, some people are accompanied by indigestion symptoms such as bloating, which is easy to cause emaciation.

(1 1) cancer. It can obviously reduce the weight of patients, mainly due to reduced intake, overeating and cancer complications. It is worth noting that if the child is emaciated for unknown reasons, it is necessary to consider whether he has malignant lymphoma, leukemia, skull tumor and so on. If adults are emaciated for unknown reasons, we should consider whether there are gastric cancer, liver cancer, esophageal cancer, intestinal cancer and so on. Women are prone to breast cancer and cervical cancer.

(12) anorexia nervosa. It belongs to one of the manifestations of neurosis. Such patients are afraid to eat. If they are forced to eat, especially a few mouthfuls, they can turn around and spit out the food and lose weight obviously. In severe cases, he is skinny, and even leads to serious heart failure and even death because of some unexpected stimulation or burden.

(13) Hypofunction of the anterior pituitary gland, also known as "Han's disease". The cause of this disease is the low function of the anterior pituitary gland, which seriously affects many physiological functions of the human body and leads to emaciation.
