Type 2 diabetes is a metabolic disorder that causes your blood sugar levels to increase. The severity of diabetes can vary quite a bit: Some people get the disease well under control, and in others it leads to other health problems over time.
There are two main types of diabetes: Type 1 diabetes usually develops in childhood or the teenage years. This disease is a result of damage to the pancreas that leaves it producing either very little insulin or none at all.
Things are different in type 2 diabetes, where insulin is made by the pancreas but the body’s cells gradually lose the ability to absorb and use the insulin. In the past, type 2 diabetes was often referred to as “adult-onset” diabetes because it is commonly diagnosed later in life. Type 2 diabetes is much more common than type 1 diabetes. About 90% of people who have diabetes have type 2 diabetes.
