The main reason for diabetic wasting is that the body is unable to utilize blood sugar and over consumes fat and protein, thus leading to wasting. Diabetic wasting may also be caused by tuberculosis, tumors, etc. It is recommended to consult a doctor in time. Diabetic patients’ absolute or relative insulin secretion is insufficient, or insulin utilization is impaired, which leads to the body’s carbohydrate, protein and fat metabolism disorders, unable to make full use of blood glucose, causing accelerated decomposition of fats and proteins, leading to weight loss, causing wasting. When diabetes is severe, it can also cause damage to multiple organs and tissues such as cardiovascular, nerve, kidney and eye, bringing about various complications. However, wasting in diabetic patients may also be caused by tumors, tuberculosis and other diseases. When there is wasting, you should actively seek medical treatment and improve relevant examinations under the guidance of the doctor, such as tumor markers, tuberculin test, etc., so as to clarify the cause of the disease. When suffering from diabetes, you need to be actively treated under the guidance of the doctor, and pay attention to low-salt, low-sugar, low-fat diet in daily life, and appropriate exercise.
