What is type 1 diabetes?

Print

Type 1 diabetes (T1D) is an autoimmune disease in which a person’s pancreas stops producing insulin, a hormone people need to get energy from food. T1D occurs in both children and adults and has nothing to do with diet or lifestyle. There is currently nothing you can do to prevent it.

People with T1D must monitor their blood-sugar level 4-6 times per day, inject multiple times a day or receive insulin continuously through a pump, and carefully balance their insulin doses with eating and daily activities throughout the day and night. However, insulin is not a cure for diabetes. Even with intensive disease management, a significant portion of their day is still spent with high or low blood-sugar levels, placing people with T1D at risk for devastating complications such as heart attack, stroke, blindness, kidney disease and amputation.
