What is diabetes?
Type I diabetes is a disease that affects the way the body uses food. In a
person with Type I diabetes, the body destroys the cells in the pancreas that
produce insulin. Insulin is a hormone that regulates the level of sugar in
the blood. Type I diabetes is also called immune-mediated diabetes, and was
formerly known as insulin-dependent diabetes.
In Type II diabetes, once known as non-insulin-dependent diabetes, the pancreas does not make enough insulin or the body cannot use it properly. We will not discuss Type II diabetes any further.
Cause:
Scientists do not know what causes Type I diabetes, but there appears to be
a genetic component to the cause. Other factors also are likely to increase
the risk for getting diabetes. Diabetes is not contagious.
Symptoms and diagnosis:
Signs and symptoms of diabetes are:
Treatment:
Treatment for Type I diabetes involves keeping the level of sugar in the blood
as close to normal (80-120 mg/dl) as possible. Treatment usually includes:
Long-term consequences of uncontrolled or poorly controlled diabetes:
Long-term outlook for diabetes if treated and controlled:
People with Type I diabetes can live happy, healthy lives if they follow their
treatment plan.
