In general, people with diabetes either have a total lack of insulin(type 1 diabetes) or they have too little insulin or cannot use insulin effectively (type 2 diabetes).
- Type 1 diabetes (formerly called juvenile-onset or insulin-dependent diabetes), accounts for 5 to 10 out of 100 people who have diabetes. In type 1 diabetes, the body’s immune system damages the cells that release insulin, eventually reducing insulin production from the body. Without insulin, cells cannot absorb sugar (glucose), which they need to produce energy.
- Type 2 diabetes (formerly called adult-onset or non-insulin-dependent diabetes) can develop at any age. It most commonly becomes apparent during adulthood. But type 2 diabetes in children is rising. Type 2 diabetes accounts for the vast majority of people who have diabetes-90 to 95 out of 100 people. In type 2 diabetes, the body isn’t able to use insulin the right way. This is called insulin resistance. As type 2 diabetes gets worse, the pancreas may make less and less insulin. This is called insulin deficiency.
How are they alike?
Both types of diabetes greatly increase a person’s risk for a range of serious complications. Although monitoring and managing the disease can prevent complications, diabetes remains the leading cause of blindness and kidney failure. It also continues to be a critical risk factor for heart disease, stroke, and a foot or leg amputations.
