Diabetes Mellitus (DM) is a chronic condition affecting 50% of adults, increasing the risk of foot ulcers and limb amputation. Uncontrolled DM can lead to hearing loss, skin infections, and Alzheimer's disease. The International Diabetes Federation (IDF) has framed criteria for diagnosing DM based on glycemia levels linked to micro-vascular complications. After diagnosis, individuals will be classified as type 1 or 2 along with 8 sub-categories. Lifestyle modifications such as dietary changes, increased physical activity, and quitting smoking can help prevent DM and slow down its progression. Early identification and intervention are crucial in controlling diabetic burden.
