There are two different types of Diabetes- Type 1 and Type 2.
Type 1 is when the pancreas stops producing insulin, and the body does not metabolize glucose. This usually occurs in children and young adults before the age of 30. An insulin supplement must be taken daily in order to help the body metabolize the glucose from the food the individual eats.
Type 2 diabetes is when the pancreas does not produce enough insulin for the body or when the cells in the body start to resist the insulin produced by the pancreas. This usually occurs in adults, thus it is called adult onset diabetes, and is typically the result of a person being obese or overweight. This type of diabetes can be controlled through the use of insulin.
