1. Type 2 diabetes occurs when the pancreas does not produce enough insulin or the body does not properly respond to insulin. It can lead to complications like damage to blood vessels, nerves, eyes, kidneys and limbs. 2. Those at higher risk include the elderly, certain ethnic groups, overweight individuals, and those with a family history. Early symptoms may include increased hunger, thirst, fatigue and frequent urination. 3. Treatment involves medications, lifestyle changes like diet and exercise, and potentially insulin therapy. Managing blood sugar levels can help prevent or delay complications through regular testing and monitoring.
