Introduction of Diabetes Mellitus

There are three major types of diabetes. The causes and risk factors are different for each type:

• Type 1 diabetes can occur at any age, but it is most often diagnosed in children, teens, or young adults. In this disease, the body makes little or no insulin. Daily injections of insulin are needed. The exact cause is unknown.
• Type 2 diabetes makes up most of diabetes cases. It most often occurs in adulthood, but teens and young adults are now being diagnosed with it because of high obesity rates. Many people with type 2 diabetes do not know they have it.
• Gestational diabetes is high blood sugar that develops at any time during pregnancy in a woman who does not have diabetes.
