Type 1 Diabetes — Guide Hub
Type 1 diabetes is an autoimmune condition where the body’s immune system attacks insulin-producing cells in the pancreas. Without insulin, the body cannot regulate blood sugar properly. It usually develops in childhood or adolescence but can occur at any age.
Key Points
- Type 1 diabetes is autoimmune and not preventable.
- People with type 1 require insulin from diagnosis.
- Symptoms often appear suddenly: excessive thirst, urination, fatigue, weight loss.
- Management requires blood glucose monitoring, insulin therapy, healthy eating, and education.
- Complications can be avoided with good long-term management.
