Types of diabetes

From telegraph.co.uk

Type 1 diabetes

Occurs when the pancreas (a small gland behind the stomach) doesn’t produce insulin – the hormone that regulates blood glucose levels. If the amount of glucose in the blood is too high, it can, over time, damage the body’s organs.
Just 10 per cent of all diabetes is type 1 but it’s the most common type of childhood diabetes.

Type 2 diabetes

The body doesn’t produce enough insulin to function properly, or the body’s cells don’t react to insulin. This means that glucose remains in the bloodstream and isn’t used as fuel for energy.
90 per cent of adults with diabetes have type 2, and it tends to develop later in life

Gestational diabetes

Around one in 20 pregnant women experience such high blood sugar that their bodies are unable to produce enough insulin to metabolise it. This needs to be managed during pregnancy but almost always clears up after giving birth.
