Health Centres - Type 1 diabetes
Term watch
The pancreas lies at the back of the abdomen and has two main functions:
- to produce a juice that flows into the digestive system to help us digest food
- to produce the hormone called insulin.
Insulin is the key hormone that controls the flow of glucose (sugar) in and out of the cells of the body.
Type 1 diabetes is caused by a lack of insulin output because of damage to the pancreas gland.
This is because this type of diabetes always requires insulin treatment.
As some people with Type 2 diabetes now also require insulin, the term Type 1 is preferred.
Auto-immune diseases
They are more frequent in people who have Type 1 diabetes.
This may reflect an inherited tendency to developing auto-immune disease that is triggered by some other factor in the environment.
Exactly what that trigger can be is still unclear, but there is some evidence to suggest that a virus infection could start the process off.
What are the symptoms of Type 1 diabetes?
The brain and nervous system use only glucose, while most other cells can also utilise fat for energy.
As a result of the lack of insulin output in Type 1 diabetes, the blood sugar level climbs and glucose starts to appear in urine.
Because glucose use becomes very inefficient, a person with untreated Type 1 diabetes develops symptoms such as:
How is Type 1 diabetes treated?
- regular injections of insulin. These are given daily or several times a day, depending on the type of insulin used. Insulin is now also available as an inhaler, but it's likely that most people for who this is suitable will still need insulin injections as well.
The goal of insulin treatment is to control the amount of insulin in the bloodstream so glucose levels are normal, or near normal.
Treatment for diabetes depends on the individual. It starts the first time you give yourself an insulin injection, and continues through starting an exercise programme and eating the right types and amounts of food.
Your healthcare team dietician, GP and diabetes nurse are all on hand to give advice and guidance.
Ways to help yourself
- Keep an eye on any signs indicating either high or low glucose levels.
There are other auto-immune diseases, for example of the thyroid gland.
Glucose is one of the key fuels used by the cells of the body for its energy needs.
Diabetes is treated by:
- staying physically active and getting plenty of exercise
- maintaining a steady weight
- eating a proper diet containing a controlled amount of carbohydrates.
- Learn how to measure glucose levels and do it regularly.
