There are three major forms of diabetes namely Type1, Type 2 and third form is known as gestational diabetes.
Type1 and Type 2 were formerly known as insulin dependent and insulin non-dependent diabetes.
It is estimated that in 2010 there were globally 285 millionpeople (approximately 6.4% of the adult population) suffering from this disease.
This number is estimated to increase to 430 million in the absence of better control or cure.
Type 1 Diabetes In type 1 diabetes mellitus, body cells fail to produce insulin due to a compromised immune system causing damage to the cells where production of insulin takes place.
Diabetes Research Paper Introduction
The cause and prevention of type 1 diabetes are not particularly known; however, it is suspected to be a consequence of certain genetic factors.
An ageing population and obesity are two main reasons for the increase.
Furthermore it has been shown that almost 50% of the putative diabetics are not diagnosed until 10 years after onset of the disease, hence the real prevalence of global diabetes must be astronomically high.
Men with lower testosterone levels are at higher risk of developing the Type2 diabetes.
Auto-immune, genetic and environmental factors play considerable role in the onset of Type 1 diabetes although the risk factors are not clearly defined.
