1. Thirst

In diabetics, high blood sugar levels will increase plasma osmotic pressure, thereby causing symptoms of thirst at night.

2. Hungry

Most diabetics have insulin resistance or insufficient insulin secretion. In this case, even if the patient has high blood sugar, they still have difficulty using blood sugar because insulin cannot work, leading to hunger.

At the same time, the higher the blood sugar level, the more difficult it is for the person to use glucose. Therefore, the body will consume more fat and protein, which will also cause hunger.

3. Increased urination

There are three main reasons for increased frequency of nocturia in diabetic patients.

First, high blood sugar can cause osmotic diuresis. When blood sugar is high, solutes in the renal tubules and collecting ducts increase, reducing the amount of water reabsorbed by the kidneys, leading to increased urination.

Second, diabetic patients themselves are prone to thirst, leading to drinking a lot of water. This will inhibit the secretion of antidiuretic hormone, which can increase the frequency of urination.

Third, poor blood sugar control can damage the kidneys, reducing their ability to reabsorb water, leading to increased urination.

4. Dry skin

High blood sugar can cause symptoms of dehydration and dry skin.

Additionally, if a diabetic patient has poor blood sugar control over a long period of time, peripheral nerves will be damaged. This can cause dermatitis, dry skin, and scaling.
