If the cachexia is caused by malignant tumor, it cannot be adjusted because the patient is at a later stage and there are no special drugs available for malignant tumor. If the cachexia is caused by chronic wasting diseases such as diabetes, it may be possible to improve the cachexia to a certain extent based on the control of the primary disease and timely and comprehensive nutritional supplementation. 1. Cachexia caused by malignant tumor: Patients with advanced malignant tumor will suffer from excessive wasting due to tumor consumption and poor diet, and may also be accompanied by water-electrolyte disorders, such as Hypokalemia, hyponatremia, etc. The cachexia that occurs at this time usually cannot be adjusted. However, it is necessary to actively treat the tumor and take nutritional support, such as enhancing transgastrointestinal nutrition, and oral nutrition solution can be taken. If patients cannot take orally, they can have intravenous nutrition, i.e. intravenous infusion therapy, through which amino acids, fat milk, electrolytes, trace elements, etc. can be input to ensure the nutritional status of patients and delay the progress of cachexia as much as possible; 2. Chronic wasting diseases leading to cachexia: If chronic wasting diseases lead to cachexia, such as diabetes, efforts should be made from various aspects such as blood sugar control and diet adjustment because Long-term high blood sugar will lead to damage to various organs of the body, and it is necessary to control blood sugar, blood pressure, blood lipids and other indicators within a reasonable range. If the blood sugar is high, metformin and insulin should be used under the guidance of a doctor, and if the patient has high blood pressure, enalapril and irbesartan should be used under the guidance of a doctor to control blood pressure. In addition, dietary adjustment should be carried out under the guidance of doctors. The total calorie intake needs to be decided according to the patient’s age, gender, height, weight, physical activity and condition, and the specific intake of carbohydrates, proteins and fats also needs to be set by doctors. The cachexia can be gradually adjusted through active medication and dietary adjustment, etc. If patients have poor dietary status or experience weight loss, try to actively seek the cause at an early stage and then treat the cause, and also actively provide nutritional support to avoid the development of cachexia. Once cachexia develops, it can have adverse effects on all organs of the patient’s body and is difficult to adjust to a normal state.
