Diabetes is a disease when glucose level in blood exceed.
Glucose—a sugar needed by all cells of the body for energy — is normally transported to the cells with the help of the hormone insulin, which is produced by the pancreas.
In type 1 diabetes, which is partly genetically inherited, the pancreas cannot make enough insulin because its insulin-producing cells have been destroyed by the body's own immune system. Thus, glucose accumulates in the blood. In contrast, people with type 2 diabetes can produce insulin, but their bodies are unable to utilize it effectively.
Type 2 diabetes may be caused by lifestyle factors, such as high consumption of sugar, in addition to genetics. Type 1 diabetes has a lower prevalence than type 2, accounting for just five to ten percent of diabetes cases.
The 2 conditions also differ by age of onset.
Type 1 diabetes often occurs in childhood.
type 2 often occurs in mid/late adulthood.
