Diabetes. What is Diabetes? HOW DO I MANAGE MY DiabeteS?

What is Diabetes?

Glucose is in our blood, and is normally kept within a tight range. We need glucose to fuel many processes in the body, including our muscles to move and our brains to think. At this normal level, glucose is needed to function and is not a problem.

Diabetes is a problem of having glucose levels that are too high.

When blood glucose levels are too high they become toxic. High blood glucose levels over time can cause problems with blood vessels, nerves, and organs. These are referred to as complications.

Where does the glucose in our body come from?

Some of this glucose in the blood comes from the food we eat. Our body also makes it's own glucose.

How does our body usually keep blood glucose within this normal range?

Our body has a mechanism to regulate glucose levels. Normally when our body senses blood glucose levels are high, a change is made to bring these levels down. The pancreas produces a hormone called insulin, which pushes glucose from the blood into the muscle, liver and fat.

So what causes blood glucose levels to go too high?

In the different types of diabetes, there is a malfunction of the inter-relationship between this insulin secretion and / or insulin action. In addition, the food we eat and the activity we do will affect these glucose levels.

Diabetes Management

The goal of diabetes management is to bring blood glucose levels into a normal range. This means blood glucose levels that don't go too high, or too low.

To do this, we need to address bodyweight, exercise,  diet, lifestyle and for some people, medication may be needed.

Depending on the type of diabetes you have, the medical management and the dietary advice given to you will vary.
