Diabetes Mellitus is a chronic condition that occurs when the body cannot properly process food for use as energy. This results in high blood sugar levels, which can lead to serious health complications if not managed effectively. There are two main types: Type 1 Diabetes, where the body does not produce insulin, and Type 2 Diabetes, where the body becomes resistant to insulin or doesn't produce enough. Managing Diabetes Mellitus involves lifestyle changes, such as a balanced diet and regular exercise, along with monitoring blood sugar levels. Medications, including insulin therapy, may also be necessary to maintain healthy blood sugar levels and prevent complications like heart disease and kidney damage.
