Type 1 Diabetes

Overview

Type 1 diabetes is an autoimmune condition where the immune system attacks insulin-producing cells in the pancreas, leading to little or no insulin production. It's not caused by lifestyle and typically develops in childhood or young adulthood, though it can occur at any age.

Symptoms

Rapid onset of increased thirst, frequent urination, extreme fatigue, unexplained weight loss, and blurred vision. Symptoms can develop quickly, over days to weeks.

Risk Factors

Family history and certain genetic factors increase risk, though many people with type 1 diabetes have no family history at all — it isn't linked to weight or lifestyle.

Common Blood Tests

Blood glucose and HbA1c confirm diabetes; specific antibody tests and C-peptide levels help distinguish type 1 from type 2.

Lifestyle Information

Type 1 diabetes always requires insulin treatment — it cannot be managed through diet and exercise alone. Blood sugar monitoring, carbohydrate awareness, and regular activity all support day-to-day management alongside insulin therapy.

When to seek medical advice

Seek urgent medical attention for rapid-onset thirst, urination, and weight loss, particularly in children — this combination needs same-day assessment, as untreated type 1 diabetes can become a medical emergency (diabetic ketoacidosis).
