Types of Diabetes


There are four types of Diabetes Clinical Cases:
Type 1 Diabetes, commonly known as juvenile diabetes, results from beta cell destruction that usually leads to insulin deficiency.
Type 2 Diabetes results form a progressive insulin secretory defect, where the body is not able to recognize insulin hormone signals needed to break down sugars and carbohydrates.
Gestational diabetes mellitus is diabetes diagnosed during pregnancy.
Other types of specific diabetes can be caused by:
  • genetic defects in beta cell function or insulin action
  • pancreatic diseases
  • drug- or chemical- induced (such as in HIV/AIDs treatment or after organ transplantation)
