What is the medical term for high blood sugar?

The medical term for high blood sugar is hyperglycemia. It occurs when the body has too much glucose circulating in the bloodstream, often due to insufficient insulin or the body’s inability to use insulin effectively. Hyperglycemia is a hallmark of diabetes mellitus, both type 1 and type 2. Symptoms include increased thirst, frequent urination, fatigue, and blurred vision. If not managed properly, it can lead to serious complications such as nerve damage, kidney failure, and cardiovascular disease. Maintaining a balanced diet, regular exercise, and appropriate medication are crucial for controlling blood sugar levels and preventing long-term damage.
