1. Type 1 Diabetes (Autoimmune) Cause: The immune system mistakenly attacks and destroys insulin-producing cells in the pancreas. Triggers: Exact causes are unclear, but genetic factors and possibly viral infections may play a role. Not linked to lifestyle. 2. Type 2 Diabetes (Lifestyle-related and Genetic) Causes: Insulin resistance – the body’s cells no longer respond properly to insulin. Poor diet – high in sugar, refined carbs, and unhealthy fats. Lack of physical activity. Obesity or being overweight. Genetics and family history. Age – risk increases after 45. Stress and hormonal imbalances. 3. Gestational Diabetes Occurs during pregnancy due to hormonal changes that affect insulin usage. Risk increases if overweight, have a family history, or had gestational diabetes in a previous pregnancy. Other Contributing Factors: Sedentary lifestyle High blood pressure or cholesterol Polycystic ovary syndrome (PCOS) Sleep issues, including sleep apnea Prevention & Management While Type 1 is not preventable, Type 2 diabetes can often be delayed or prevented with healthy lifestyle choices, including a balanced diet, regular exercise, and routine check-ups.
