What Causes Diabetes?What Causes Diabetes?

• Type IType I--The pancreas is unable to produce insulin. The pancreas is unable to produce insulin. Childhood and genetic tendency are two possibilities. Childhood and genetic tendency are two possibilities. There’s a change in the pancreatic function and the There’s a change in the pancreatic function and the cells that normally produce insulin are destroyed. The cells that normally produce insulin are destroyed. The body’s own immune system may think the pancreas is a body’s own immune system may think the pancreas is a foreign body! This form often appears at a time of foreign body! This form often appears at a time of physical stress or during illness when the body produces physical stress or during illness when the body produces more glucose. Unable to metabolize carbohydrates.more glucose. Unable to metabolize carbohydrates.

• Type IIType II--The pancreas can still produce insulin but the The pancreas can still produce insulin but the amount is inadequate and/or the insulin can’t be used to amount is inadequate and/or the insulin can’t be used to its full extent by the tissues. Most people who have this its full extent by the tissues. Most people who have this type are overweight. This type is the most prevalent.type are overweight. This type is the most prevalent.
