🔍 What causes it
Type 1: the immune system destroys insulin-producing cells (needs insulin lifelong). Type 2: the body becomes resistant to insulin — strongly linked to weight, inactivity and family history. Gestational diabetes appears during pregnancy.
⚠️ Key symptoms
- Excessive thirst and frequent urination
- Unintended weight loss
- Blurry vision and slow-healing wounds
- Fatigue and recurring infections
💊 Treatment
Type 1: insulin. Type 2: lifestyle (diet, movement, weight) plus metformin and other medicines as needed. Regular blood sugar checks, foot care and eye exams are essential. Untreated diabetes damages heart, kidneys, eyes and nerves.
🛡️ Prevention
Type 2 largely preventable: healthy weight, regular activity, fibre-rich diet, limit sugary drinks, get screened if you have risk factors (family history, age, overweight).
🚨 See a doctor / red flags: See a doctor promptly if symptoms are severe, do not improve, or get worse — especially for children, older adults, pregnant women, or anyone with a chronic condition.
