There are many reasons for thinness. In addition to life factors such as malnutrition and excessive labor consumption, some potential physical diseases can also lead to weight loss. 1. hyperthyroidism: This is an endocrine disease. Due to the increase of metabolism, the body has an overeating appetite, but too many nutrients are decomposed in the body, which greatly consumes fat and protein in the body, resulting in weight loss, sometimes as high as 65,438+00 kg in a short time. If there is no obvious other reason leading to emaciation in clinic, this disease is most likely. Symptoms include overeating and emaciation, as well as rapid heartbeat, hyperhidrosis, goiter in the neck, hand tremor and emotional excitement. A few patients have no goiter or only mild goiter, and have no emotional symptoms of hyperthyroidism, but they can be diagnosed by laboratory examination. 2. Diabetes: manifested as "three excesses", that is, polyuria, polydipsia and polyphagia. A large amount of sugar is excreted from urine, and the catabolism of fat and protein increases, resulting in excessive consumption and gradual weight loss. About 40.6 ~ 56.6% of them are emaciated due to diabetes, and of course many patients are obese. There are also tuberculosis, malignant tumors, hematological diseases, gastrointestinal diseases, etc., which will all lead to emaciation.

Only by finding out the reasons and taking targeted measures can we gain weight gradually. According to your letter, hyperthyroidism is the most likely, so you should go to the hospital for examination and take medicine after a definite diagnosis. After your illness is cured, your body will gradually become stronger.

(1) Normal appetite and weight loss. Weight loss caused by abnormal digestion and absorption function, such as vomiting, diarrhea, parasitic diseases, etc.

(2) When the food intake increases, the body weight decreases. Although eating more, but the consumption increases, so as to lose weight, such as hyperthyroidism, diabetes and so on.

(3) Loss of appetite, decreased food intake and excessive body catabolism lead to weight loss, such as ① systemic diseases (infection, malignant tumor, hematological diseases), hypofunction of adrenal cortex and hypofunction of anterior pituitary gland; ② Mental factors: depression, anorexia nervosa; ③ Digestive system diseases: chronic gastrointestinal diseases, chronic liver diseases, chronic pancreatic diseases, etc.

(4) Severe trauma and burns, often accompanied by a large amount of plasma exudation, significantly increased consumption of protein;

(5) Some drug reasons, such as thyroid preparations and long-term use of laxatives. Emaciation is characterized by rough and inelastic skin, muscular atrophy, reduced subcutaneous fat and exposed bones.

Emaciation caused by various reasons will have corresponding clinical manifestations, such as hyperthyroidism patients, which can be seen as cervical swelling, bright eyes, overeating, sweating, emaciation, palpitation, shaking hands, increased stool frequency and so on. Your weight is less than 10% of the standard weight, which belongs to emaciation. At present, you also ruled out hyperthyroidism, normal diet, abnormal defecation, and colon dysfunction. Intestinal dysfunction, in addition to alternating symptoms of constipation and diarrhea, can also appear abdominal distension, abdominal pain and some symptoms of systemic neurosis, generally without wasting. I suggest you go to the hospital to consult a specialist, comprehensively relieve other situations except diet and defecation, and relieve your troubles as soon as possible.
