There are generally three types of diabetes. Type I diabetes is caused where the body does not produce insulin and hence, is referred to as juvenile diabetes or early-onset diabetes. Type II diabetes refers to a condition where either the body does not produce enough insulin for proper function or the cells in the body do not react to the insulin produced. Gestational diabetes occurs in women during pregnancy when they have high levels of glucose in their blood, but their bodies are unable to produce enough insulin to transport all the glucose into their cells. This further leads to progressively rising levels of glucose. In India, type 2 diabetes is more common than other forms.
