The American Diabetes Association adopted the following classification in 1979.
Type –1, insulin-dependent diabetes mellitus
Type-2, non insulin-dependent diabetes mellitus
There are two other kinds of diabetes, known as gestational diabetes and secondary diabetes. There is also a special kind of diabetes in India called malnutrition related diabetes.
Type-1 Insulin-Dependant Diabetes
This is the most severe form of diabetes. It develops when pancreas makes little or no insulin. Without insulin in the blood stream, sugar does not get into the cells, and remains in the blood. People with type-1 diabetes depend on injections of insulin to regulate their smaller metabolism.
Type-2 Non Insulin Dependent Diabetes
This type of diabetes is also known as adult onset diabetes. It seldom develops before the age of 40 years, although it may occur at any stage. Infect the incidence of type-2 diabetes in adolescents in on the rise. But because the symptoms are milk, these may not notice and the condition remains undetected for a long period and till later years.
One common factor in both type-1 and type-2 diabetes is elevated blood sugar levels. However, unlike type-1 diabetes, type-2 is not a disease of the immune system. While people with type-1 diabetes must use insulin to live, most of those with type-2 diabetes are able to control the disease and even reverse it. This is possible by a combination of appropriate diet, proper weight control and adequate exercise.
