What are the initial symptoms of diabetes?

summary

The theme of this year's "World Diabetes Day" is "diabetes education and prevention", which reflects the important principle of diabetes treatment: Although diabetes can not be cured at present, early detection and treatment of diabetes is reversible and curable. Scientific understanding of diabetes and paying attention to improving lifestyle are the basis of prevention and treatment of diabetes. What are the initial symptoms of diabetes? Let's study and discuss with you.

What are the initial symptoms of diabetes?

Weight loss: Although patients with diabetes have normal appetite and food intake, or even increase, weight loss is mainly due to absolute or relative lack of insulin or insulin resistance. The body can not make full use of glucose to produce energy, resulting in increased fat and protein decomposition, excessive consumption, negative nitrogen balance, gradual weight loss, and even emaciation.

Polyphagia: it is caused by the decrease of glucose utilization rate (glucose concentration difference in arteriovenous blood before and after entering and leaving tissue cells). In normal people, the glucose concentration difference in arteriovenous blood shrinks during fasting, which stimulates the feeding center and produces hunger. After feeding, the blood glucose rises, and the body can not make full use of glucose. A large amount of glucose is excreted from the urine, so the body is actually in a semi hungry state, Lack of energy also causes hyperappetence.

Visual acuity decline: many diabetic patients complain of visual acuity decline or blurring when they see a doctor in the early stage, which may be caused by the change of lens osmolality caused by hyperglycemia and the change of lens diopter. In the early stage, it is generally a functional change. Once the blood glucose is well controlled, the vision can quickly return to normal.

matters needing attention

1. Check whether the soles of feet are damaged or injured in the morning and evening, and pay special attention to the hidden position of feet. 2. Wear loose shoes and suitable shoes to prevent foot wear caused by sole pressure during walking. 3. Regular screening of nerve function and blood vessels. 4. Pay attention to control blood sugar, blood pressure and blood lipid in daily life and diet to prevent complications. 5. It's best to wear socks in daily life, but in rainy season, you can't wear too thick socks to prevent mold infection. 6. For diabetic patients who have the habit of foot soaking and foot bathing, it should be noted that the foot soaking time should be controlled within 30 minutes, and the temperature should preferably be within 40 ℃, which should not be based on the feeling of the patients.
