summary

Diabetes is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by the deficiency of insulin secretion or the impairment of its biological function, or both. Hyperglycemia exists for a long time in diabetes, which leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels and nerves. Early symptoms of diabetes mellitus? Next, I'd like to share my views with you.

Early symptoms of diabetes mellitus?

Severe hyperglycemia, the typical "three more less" symptoms, more common in type 1 diabetes. When ketosis or ketoacidosis occurs, "three more and less" symptoms are more obvious. More common in type 2 diabetes. Obesity often occurs before the onset of type 2 diabetes. If not diagnosed in time, the weight will gradually decrease.

It is often positive. When the blood glucose concentration exceeds the renal glucose threshold (160-180 mg / dl), the urine glucose is positive. When the renal glucose threshold is increased, even if the blood glucose reaches the level of diabetes, the diagnosis can be negative. Therefore, urine glucose determination is not a diagnostic standard. In ketosis or ketoacidosis, the urine ketone body is positive.

It is a non enzymatic reaction product of glucose and hemoglobin. The reaction is irreversible and the level of HbA1c is stable. It can reflect the average blood glucose level in two months before blood collection. It is the most valuable index to judge the state of blood glucose control. The product of non enzymatic reaction between blood glucose and serum albumin reflects the average blood glucose level 1-3 weeks before blood collection.

matters needing attention

Fat is high in energy, producing 9 kilocalories per gram. It accounts for about 25% of the total calories, generally less than 30%, and 0.8-1g per kilogram of body weight per day. Animal fat mainly contains saturated fatty acids. Vegetable oil is rich in unsaturated fatty acids, and diabetic patients are prone to atherosclerosis.
