  1. DIFFERENCE BETWEEN TYPE 1 & TYPE 2 DIABETES
  Type 1 DM Type 2 DM
Other names Juvenile Onset diabetes  Insulin-dependent diabetes (IDDM) Adult Onset Diabetes  non-insulin dependent diabetes (NIDDM)
Description Little or no Insulin produced by the pancreas (Absolute Insulin deficiency) Pancreas does not make enough insulin or body does not use insulin correctly.
Usual age of Onset < 30 years old 40-60 years old but recently occurring more frequently in children or young adults
Control by oral medication No Yes in the beginning
Requires Insulin Yes Not usually in the beginning; however as the disease progresses, Insulin is frequently needed to control blood glucose levels.
