Body wasting includes simple (physiological) wasting and secondary (pathological) wasting. Simple wasting can be improved through dietary adjustments, psychological care, etc. Secondary wasting is commonly treated with medication and surgery. Doctors will give individualized treatment plan according to the type and severity of wasting. Simple wasting is hereditary to a certain extent, and may also be caused by psychological factors such as insufficient food intake, mental tension and stress. It can be relieved by diet and emotional adjustment, such as developing good eating habits, providing reasonable meals, supplementing nutrition and avoiding partiality. Maintain an optimistic mindset, have a regular work and rest schedule, and avoid mental stress and overwork. Secondary wasting is secondary to a variety of diseases, such as gastritis, hyperthyroidism, etc., and needs to be treated for the cause. For example, patients with gastritis can use omeprazole, aluminum hydroxide, bismuth potassium citrate, domperidone and other medicines according to the doctor’s prescription; for gastric hemorrhage, gastric perforation and other lesions, it is also necessary to give surgical treatment. Patients with hyperthyroidism commonly use antithyroid drugs such as propylthiouracil, carbimazole, and methylthiouracil, etc. Subtotal thyroidectomy can also be considered for those who meet the indications for surgery. If a person with body wasting cannot be relieved by self-adjustment or if other uncomfortable symptoms appear, he should consult a doctor in time and be given targeted treatment after a clear diagnosis by a doctor. Meanwhile, when treating the primary disease, it is necessary to have a balanced diet and pay attention to nutrition.
