Diabetes is a chronic metabolic disorder that occurs when the body cannot effectively regulate blood sugar (glucose) levels. This happens due to either insufficient insulin production or the body’s inability to use insulin properly. Insulin is a hormone produced by the pancreas that helps glucose enter cells to provide energy. When this process is disrupted, glucose builds up in the bloodstream, leading to high blood sugar levels (hyperglycemia). If left uncontrolled, diabetes can lead to serious health complications affecting the heart (cardiovascular diseases), kidneys (diabetic nephropathy), eyes (diabetic retinopathy), nerves (neuropathy), and other vital organs.
