What are the dangers of high blood sugar?

Blood is the most important means of nutrient transport for the human body. Sugar is the nutrient that is transported to various parts of the body through the blood. The level of sugar in the blood is also called the blood sugar value. The higher the better, nor the lower the better, the blood sugar level must be maintained at a constant level. For example, high blood sugar is an important manifestation of diabetes. This condition has appeared more and more frequently in recent years, causing great harm to people's health. Therefore, paying attention to blood sugar levels is of great significance to protecting your health. Let’s take a look at the dangers of high blood sugar. I hope everyone can understand something.

1. Leading to dehydration and hyperosmotic state of the body: High blood sugar causes a large amount of glucose to be excreted in the urine, causing osmotic diuresis, leading to dehydration of the body. Dehydration increases the osmotic pressure of the extracellular fluid, and water transfers from inside the cells to outside the cells, causing intracellular water loss. Water loss in brain cells can cause brain dysfunction and even coma, which is clinically called "hyperosmotic coma."

2. Fatigue and weakness: Due to the lack of insulin, the glucose in the blood cannot enter the cells normally to burn and generate energy, and the cells cannot obtain enough energy. Moreover, the cells cannot convert glucose into other substances for storage. When blood sugar exceeds the renal retention value, the sugar is excreted in the urine, causing a waste of energy in the body, so the whole body feels tired and weak.

3. Reduced resistance: Under high blood sugar conditions, glucose cannot be absorbed and utilized by the body very well but is lost in large quantities in the urine. The body provides energy by breaking down fat and protein, resulting in a decrease in the body's immunity.

4. Metabolic disorders: When blood sugar is high, the body's protein and fat will have metabolic disorders, which can cause various complications. Acute complications include ketoacidosis and hyperosmolar coma. Hyperosmolar coma is mainly caused by high blood sugar, which can sometimes reach 500-600 mg/d1. It can cause dehydration of brain cells and other tissue cells, leading to coma.
