Diabetes is a health condition that is usually expressed in one of two forms – type 1 diabetes and type 2 diabetes. Although the two types have very different causes, both conditions have similar early signs and symptoms, the only difference being that symptoms of type 1 diabetes tend to develop faster. The symptoms are typically linked to the excess sugar in the bloodstream, and lack of sugar reaching cells. It is vital to know what these signs and symptoms are in case you or someone you know experiences them. Early diagnosis for both type 1 and type 2 diabetes can be extremely important.
