Abstract

The purpose of this article is to provide a general update of diabetes with a focus on newer developments that may impact risk assessment. The main reasons for concern about diabetes are the associated microvascular and macrovascular complications. Control of blood glucose levels, primarily assessed by measurement of hemoglobin A1c, has been shown to reduce the occurrence of microvascular complications. In conjunction with control of other risk factors, control of blood glucose levels reduces the occurrence of macrovascular complications. Type 1 diabetes is now known to be an autoimmune disease. For unknown reasons, the patient's immune system destroys its own pancreatic insulin-producing beta cells. The hallmark of type 2 diabetes is insulin resistance, which may be mediated by one of a number of gene defects. At some point, the pancreatic beta cells are unable to compensate for the insulin resistance by increasing insulin secretion. Type 2 diabetes then appears. Prediabetes, encompassing impaired fasting glucose and impaired glucose tolerance, is an important clinical entity that precedes the diagnosis of diabetes in many cases. Diet and exercise are the most important interventions for reducing the progression of insulin res...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
