Elevated blood sugar

Introduction 1. Hyperglycemia means that fasting blood glucose is higher than the upper limit of 7.3mmol/L (130mg/dl), and blood glucose is higher than the renal sugar threshold of 9.0mmol/L (160mg/dl). 2, short-term high blood sugar has no serious damage to the human body, such as when under stress or when you are emotionally excited, when you are nervous, when you eat a lot of sugar at a time. Subsequently, blood sugar levels will gradually return to normal. 3. If blood sugar cannot be lowered, then persistent high blood sugar will develop into diabetes.

Cause

The cause of elevated blood sugar levels:

1. Impaired islet function and insufficient insulin secretion.

2. Insulin secretion lags, making postprandial blood sugar rise.

3. It has insulin resistance, although insulin secretion can be, but it is not sensitive to insulin utilization.

The main reason for the rise in blood sugar in normal people is that they have just eaten, or use a large amount of sugar at a time. The main cause of normal blood sugar is less than 80mgdl is hunger.

Check for elevated blood sugar levels

Blood sugar, the glucose in the blood, is one of the energy sources of the body. The blood glucose levels in normal adults were: fasting blood glucose (FBS): 3.6-6.1 mmol/L (69-109 mg/dl), 2 hours postprandial blood glucose (20 PBS): 3.6-7.7 mmol/L (65-139 mg/dl).

When measuring blood sugar, you should pay attention to the fasting blood sugar, the time should be within 12 hours; 2 hours after the meal, the blood sugar is calculated from the first meal. The following can be diagnosed as diabetes.

1 Blood glucose was measured 1 hour after oral administration of 75 g of glucose, if blood glucose was 11.1 mmol/L (200 mg/dl).

2 Another fasting blood glucose 7.8mmol / L (140mg / dl).

3 Another time after oral administration of 75 g of glucose on an empty stomach, blood glucose was measured to be 11.1 mmol/L (200 mg/dl).

Differential diagnosis

Symptoms of elevated blood sugar levels

High blood sugar after meal: The second clinical manifestation of type 2 diabetes is that the resistance is aggravated. Although hyperinsulinemia, but the receptor is less sensitive, there is still postprandial hyperglycemia; the performance is normal fasting blood glucose but after meal Blood sugar rises.

High blood sugar during pregnancy: refers to diabetes during pregnancy or varying degrees of impaired glucose tolerance, that is, first pregnant, then diabetes. More diagnosed in the 24th to 28th week of pregnancy. After the delivery, most patients will return to normal blood sugar and the symptoms of diabetes disappear. About 20% of patients develop type 2 diabetes several years or decades after delivery.

Elevated blood sugar: The sugar in the blood is called blood sugar, and in most cases it is glucose. Most of the energy required for cell activity in various tissues in the body comes from glucose, so blood sugar must be maintained at a certain level to maintain the needs of various organs and tissues in the body. Normal people have a fasting blood glucose concentration of 80 to 120 mg% in the morning. Fasting blood glucose levels above 130 mg% are called hyperglycemia. If the blood glucose concentration exceeds 160-180 mg%, a part of glucose is excreted in the urine, which is diabetes. Elevated blood sugar is common in diabetes.
