What can lead to diabetes?

There are two different types of diabetes, Type 1 and Type 2, both are very harmful to your body if not taken care of properly. You can inherit a predisposition to the disease. Environmental factors also play a key role in triggering each type. In most cases a child needs to inherit risk factors from both parents to be at high risk of type 1 diabetes. Researches also think that early exposure to viruses may trigger type one diabetes in a person. Some type one diabetics have autoantibodies found in their blood that may have been there years before they developed the disease. Researchers are still trying to find out how genetics and environment come together with this disease that is becoming more and more common. In type two diabetes it is almost all environment. Obesity is a key problem in the development of type two. Researchers are unsure if it is more environment or genetic susceptibility.

I believe that type two diabetes is mostly due to environmental causes and the treatment of ones body, but type one seems to be easily passed down through generations. I believe that exercise, food, and exposure to viruses may also be a big issue in type one diabetes development.
