Diabetes, or sugar disease, occurs when blood sugar (glucose) levels rise excessively. It has two types: Type 1, where the body produces no insulin, and Type 2, where insulin usage is impaired. Symptoms include excessive thirst, frequent urination, fatigue, and blurred vision. Managing diabetes requires lifestyle changes, a balanced diet, regular exercise, and medication. Uncontrolled diabetes can lead to severe complications like heart disease and kidney issues, making effective management essential for overall health.
