Diabetes is a chronic condition that affects how the body processes blood sugar (glucose). It occurs when the body either doesn’t produce enough insulin (Type 1 diabetes) or can’t use insulin effectively (Type 2 diabetes). High blood sugar levels can lead to serious health complications, including heart disease, kidney damage, and nerve problems. Managing diabetes involves a healthy diet, regular exercise, medication, and monitoring blood sugar levels. Early detection and proper care can help prevent complications and improve quality of life.
