What Is Diabetes?

What is Diabetes?

Diabetes is a serious, lifelong condition where your blood glucose level is too high. There are two main types of diabetes, Type 1and Type 2. These are different conditions, but they’re both serious.

What causes diabetes?

All types of diabetes have 1 thing in common and that is that they cause people to have too much glucose (sugar) in their blood. But of course, we all need some glucose…it’s our energy!

We also need a hormone called insulin which is made by our pancreas, and it’s insulin that allows the glucose in our blood to enter our cells and fuel our bodies.

Type 1 Diabetes

Type 1 diabetes affects the body such that it can no longer produce insulin. Type 1 diabetes is an autoimmune disease that causes the insulin producing beta cells in the pancreas to be destroyed, preventing the body from being able to produce enough insulin to adequately regulate blood glucose levels.

Insulin dependent diabetes is another term that may sometimes be used to describe type 1 diabetes.

Because type 1 diabetes causes the loss of insulin production, it therefore requires regular insulin administration either by injection or by insulin pump.

Type 2 Diabetes

Type 2 diabetes is one of the most common long-term health conditions

Type 2 diabetes mellitus is a metabolic disorder that results in hyperglycemia (high blood glucose levels).

Type 2 diabetes is characterised by the body being unable to metabolise glucose (a simple sugar). This leads to high levels of blood glucose which over time may damage the organs of the body. From this, it can be understood that for someone with diabetes something that is food for ordinary people can become a sort of metabolic poison.

The good news is for very many people with type 2 diabetes this is all they have to do to stay well. If you can keep your blood sugar lower by avoiding dietary sugar, likely you will never need long-term medication.

Life Expectancy

People with type 1 diabetes, on average, have shorter life expectancy by around 20 years. People with type 2 diabetes, on average, have shorter life expectancy by around 10 years.
