Diabetes is a chronic health condition that affects how the body regulates blood sugar (glucose). It occurs when the body either cannot produce enough insulin or cannot effectively use the insulin it produces. Recognizing the different types of diabetes and their symptoms is crucial for early detection and effective management.
