Type 1 diabetes is a disease in which the pancreas does not produce any insulin. Insulin is a hormone that helps your body to control the level of glucose (sugar) in your blood. Without insulin, glucose builds up in your blood instead of being used for energy.
Your body produces glucose and also gets glucose from foods like bread, potatoes, rice, pasta, milk and fruit.
The cause of type 1 diabetes remains unknown. It is not caused by eating too much sugar, and is not preventable. The current thought is that type 1 diabetes occurs when the body’s immune system destroys the cells that make insulin.
Insulin therapy is required for the treatment of type 1 diabetes.
There are a variety of insulins available to help manage diabetes. Insulin is injected by pen, syringe or pump. Your doctor will work with you to determine:
The number of insulin injections you need per day
The timing of your insulin injections
The dose of insulin you need with each injection
The insulin treatment your doctor prescribes will depend on your goals, age, lifestyle, meal plan, general health and motivation. Social and financial factors may also need to be considered.
The good news
You can live a long and healthy life by keeping your blood glucose (sugar) levels in the target range set by you and your health-care provider:
You can do this by:
Taking insulin as recommended (and other medications, if prescribed by your doctor)
Monitoring your blood glucose (sugar) levels regularly using a home blood glucose meter*
Eating healthy meals and snacks
Enjoying regular physical activity
Aiming for a healthy body weight
Managing stress effectively
* Discuss with your health-care provider how often you should measure your blood glucose (sugar) level.
