Types of Diabetes
Type 1 diabetes (T1D): The body stops producing insulin or produces too little insulin to regulate blood glucose level.
Type 2 diabetes (T2D): Although the pancreas still secretes insulin, the body of someone with type 2 diabetes is partially or completely unable to use this insulin. This is sometimes referred to as insulin resistance. The pancreas tries to overcome this resistance by secreting more and more insulin. People with insulin resistance develop type 2 diabetes when they fail to secrete enough insulin to cope with their higher demands.
Gestational diabetes (GDM) is a form of diabetes that occurs during the second half of pregnancy.
Metabolic syndrome (also referred to as syndrome X) is a set of abnormalities in which insulin-resistant diabetes (type 2 diabetes) is almost always present along with hypertension (high blood pressure), high fat levels in the blood (increased serum lipids, predominant elevation of LDL cholesterol, decreased HDL cholesterol, and elevated triglycerides), central obesity, and abnormalities in blood clotting and inflammatory responses. A high rate of cardiovascular disease is associated with metabolic syndrome.
Prediabetes is a common condition related to diabetes. In people with prediabetes, the blood sugar level is higher than normal but not yet high enough to be considered diagnostic of diabetes.
About 17 million Americans (6.2% of adults in North America) are believed to have diabetes. It has been estimated that about one third of adults with diabetes do not know they have diabetes.
