Type 1 Diabetes
Type 1 diabetes is believed to be an autoimmune condition. It 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.
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 happens when the body doesn't produce enough insulin to function properly, or the body's cells don't react to insulin. This means glucose stays in the blood and isn't used as fuel for energy.
Type 2 diabetes is usually associated with obesity and is more common than type 1 diabetes. It is a serious medical condition that needs medication in order to keep blood sugar levels under control.
Gestational diabetes happens when women have hyperglycemia (high blood glucose levels) during pregnancy and this condition can occur at any stage of pregnancy, but is more common in the second half.
Gestational diabetes can cause problems for both mother and baby during and after birth. But the risk of these problems happening can be reduced if it's detected and well managed.
