Diabetes is a chronic condition that affects how the body regulates blood sugar (glucose), which is essential for energy. It occurs when the pancreas either produces little or no insulin (Type 1 diabetes) or when the body becomes resistant to insulin (Type 2 diabetes), leading to high blood sugar levels. Gestational diabetes can also develop during pregnancy but usually resolves after childbirth. Common symptoms include frequent urination, excessive thirst, fatigue, and slow wound healing. If left unmanaged, diabetes can lead to severe complications such as heart disease, kidney failure, nerve damage, and vision problems. Management includes maintaining a healthy diet, regular physical activity, blood sugar monitoring, and, in some cases, medication or insulin therapy. Lifestyle modifications, such as weight management and stress reduction, play a crucial role in preventing and controlling the condition. Early diagnosis and proper management can help individuals with diabetes lead healthy and fulfilling lives.
