What is Type 1 Diabetes

After food is eaten, it breaks down into glucose (sugar). The pancreas, which makes insulin, helps the body use glucose for energy. A person with type 1 diabetes does not make insulin. Without insulin, glucose cannot move into the cells. Glucose builds up in the bloodstream and is passed into the urine.

The common signs of diabetes are:

  • increased urination (peeing)
  • thirst
  • weight loss
  • tiredness
  • nausea and vomiting (sometimes)
  • breath that smells like sweet nail polish remover

About 1 in 500 children have type 1 diabetes, also known as insulin dependent diabetes mellitus, or juvenile diabetes.

Causes of Type 1 Diabetes

No one knows for sure what causes type 1 diabetes. But we do know that eating too much sugar does NOT cause type 1 diabetes. Researchers think a combination of three things is involved:

  • genetic factors
  • an environmental trigger (perhaps viruses)
  • an autoimmune response (the body destroys its own insulin producing cells)

Tips from the Trenches

Remember: Nothing could have been done to prevent your child from developing diabetes. No one is to blame. This is a tough one for many of us parents to believe. As parents, we often believe that it is our job to protect our children, so if something bad happens to them, it must be our fault; somehow we failed to do our job as protector. But we cannot say emphatically enough: THIS IS NOT YOUR FAULT, regardless of what that well-meaning but uninformed neighbour or teacher or second-cousin-twice-removed had to say on the subject. When my son was diagnosed, I had people ask me if he had eaten too much sugar; some asked if he had been overweight/inactive or where he had “caught” diabetes. The reality is that, given our current knowledge of the cause of type 1 diabetes, there is nothing you could have done to prevent this.

Treatment of Type 1 Diabetes

At present, there is no cure for type 1 diabetes. However, it can be effectively managed so that your child doesn’t miss out on normal childhood activities. Type 1 diabetes is treated by:

  • balancing carbohydrate (sugar- or glucose-containing food) with injected insulin (Insulin can be delivered with a syringe, pen device or insulin pump.)
  • checking blood glucose

Diabetes Management involves juggling the three main factors that affect blood glucose. These are:

  • food
  • insulin
  • activity

(Food increases blood glucose; insulin and activity generally decrease blood glucose.)

The goals of diabetes management are:

  • keeping the blood glucose as close to normal as possible (normal BG is 4-7 mmol/L)*
  • ensuring normal growth and development
  • promoting social and emotional well-being
  • reducing the risk of long-term complications

*Actual blood glucose targets may vary according to, among other things, your child’s age. It’s typically 6-10 mmol/L for younger kids and moves to 4-7 mmol/L when they become very aware of their lows. For example, when my (Michelle’s) son was diagnosed as an infant, his blood glucose targets were 7.0 for the daytime and 9.0 overnight.

Remember: Your child is a child first and a child with diabetes second. Diabetes does not have to stop your child from taking part in normal childhood activities.
