There are two forms of Diabetes Mellitus. The most common form involving the two will be the second type. Type 2 Diabetes is additionally medically referred to as noninsulin-dependent Diabetes Mellitus. Compared to Type 1, the pancreatic beta cells of the people with Type 2 Diabetes produce insulin. In fact, in the event the the hormone insulin level is measured, it could be seen to be low, normal or high. However, there are abnormalities of insulin secretion along with abnormal responses towards the insulin at the cellular level. In the case of RA, you may feel tired or suffer from loss of appetite due to inflammation caused by immune system activity. You may also become anemic - meaning you have fewer red blood cells - or have a mild fever. Severe RA may lead to joint deformities, if not treated.
