Too thin. What is the problem with the body

Being underweight may be related to factors such as digestive and absorptive disorders, endocrine disorders, chronic wasting diseases, psychological factors, or genetic constitution. Long term emaciation may be accompanied by problems such as malnutrition and weakened immunity, and the cause should be determined based on specific symptoms.

1. Digestive malabsorption

gastrointestinal dysfunction such as chronic gastritis and irritable bowel syndrome can affect the breakdown and absorption of nutrients. Insufficient gastric acid secretion or imbalanced gut microbiota may lead to inadequate digestion of protein and fat in food, resulting in symptoms such as loose stools and postprandial bloating. It is suggested that the cause of disease should be identified through gastroenteroscopy. A small number of meals can be eaten daily and easily digested foods such as rice porridge and steamed eggs can be selected.

2. Endocrine disorders

hyperthyroidism can accelerate the body's metabolic rate, leading to excessive calorie consumption. Diabetes patients may have progressive weight loss due to insulin deficiency, often accompanied by polydipsia and polyuria. Female hypothalamic amenorrhea can also cause weight loss, and thyroid function, blood glucose, and sex hormone levels need to be tested for diagnosis.

3. Chronic wasting disease

tuberculosis, malignant tumor and other diseases will lead to the high metabolism of the body. Tuberculosis patients often have low-grade fever and night sweats, while tumor patients may have local lumps or abnormal bleeding. This type of disease requires clear diagnosis through imaging examination and pathological biopsy, and timely anti tuberculosis or anti-tumor treatment.

4. Psychological factors

Long term anxiety and depression may suppress appetite and central nervous system function, and severe cases may develop into anorexia nervosa. These patients often have cognitive biases about their weight, accompanied by symptoms such as amenorrhea and slowed heart rate. Psychological intervention combined with nutritional support is crucial, and hospitalization for enteral nutrition treatment may be necessary when necessary.

5. Genetic constitution

Some populations may exhibit a lean body shape but normal physical examination due to high basal metabolic rate or low muscle content. If there is no discomfort such as fatigue or dizziness, this type of situation usually belongs to physiological emaciation. Strength training can increase muscle mass, and daily intake of high calorie healthy foods such as nuts and dairy products can be appropriately increased.

It is recommended that thin individuals regularly monitor their weight changes to ensure sufficient daily intake of high-quality protein and complex carbohydrates. It is advisable to increase the intake of healthy fats such as olive oil and avocado, and avoid drinking coffee or strong tea on an empty stomach. If accompanied by persistent fatigue, low-grade fever and other symptoms, it is necessary to complete blood routine, tumor markers and other examinations to rule out organic diseases. In terms of exercise, impedance training combined with aerobic exercise is recommended to gradually increase muscle mass.
