The symptoms of high blood sugar are as follows:

High blood sugar is a major problem for many people. Generally speaking, when blood sugar rises, people's bodies will also have abnormal reactions. So, what are the symptoms of high blood sugar?

1. Rapid heartbeat and slow and deep breathing.

Even without strenuous exercise, you may feel your heart rate is significantly faster than before and your breathing is difficult.

2. Extremely thirsty.

Frequent urination reduces the amount of water in the body. When the total amount of water in the body decreases by 1-2%, it can arouse the thirst center in the brain and make people want to drink, resulting in the physiological phenomenon of extreme thirst.

3. Urine sugar test is positive.

This is also an important symptom of high blood sugar.

4. Frequent urination, dry skin, and dehydration.

Polyuria refers not only to an increase in the frequency of urination, but also an increase in the amount of urine, which can reach more than 20 times in 24 hours. Some people with high blood sugar can have a urine volume of 2-3 liters or even as much as 10 liters. There may even be a lot of foam in the urine, and the urine may be white and sticky. Polyuria is caused by an increase in blood sugar, which exceeds the renal glucose threshold (8.9~10mmol/l), and more sugar is excreted in the urine, so the frequency and amount of urination increase.
