The health condition characterized by high blood sugar levels is known as diabetes. There are mainly two types: Type 1 and Type 2 diabetes. Type 1 diabetes occurs when the pancreas produces little or no insulin, while Type 2 involves insulin resistance due to factors like obesity and lack of physical activity. High blood sugar can lead to serious complications over time, including heart disease, nerve damage, and kidney function impairment. Management typically includes lifestyle changes, such as diet and exercise, as well as monitoring blood sugar levels and may require medication or insulin therapy for maintenance.
