Diabetes
Diabetes mellitus is a chronic disease involving abnormalities in the body's ability to use sugar.
There are 20.8 million children and adults in the United States, or 7% of the population,
who have diabetes. While an estimated 14.6 million have been diagnosed with diabetes,
unfortunately, 6.2 million people
(or nearly one-third) are unaware that they have the disease.
Diabetes is characterized by:
Elevated blood sugars for months to years.Often recognized in patients and their families by excessive urination, thirst, weight loss and/or
a lack of energy. But diabetes is often silent and may exist for many years without the individual's
noticing it.
Both hereditary and environmental factors leading to its development and progression.
A relative or absolute deficiency of effective circulating insulin. Insulin is a substance made
by the pancreas which lowers blood sugar in conjunction with meals.
Diabetes is characterized by either:
(1) an inability of the pancreas to produce insulin (type 1 or insulin-dependent diabetes
mellitus) or an inability of insulin to exert its normal physiological actions (type 2 or non-insulin
dependent diabetes).
Effects certain "target tissues," that is, tissues which are vulnerable to the damaging effects of
chronically high blood sugar levels. These target tissues are the eye, the kidney, the nerves and
the large blood vessels, such as in the heart.
Diabetes is of primarily two types - Diabete mellitus (Type-I and Type II) and Diabetes insipidus.
What is type-1 diabetes?
Type-1 diabetes is sometimes called juvenile diabetes, or insulin-dependent diabetes.
It means that your body can't make insulin. Insulin helps your body turn the sugar from
the food you eat into a source of energy. Type 1 occurs more frequently in children and
young adults, but accounts for only 5-10% of the total diabetes cases nationwide.
What is type-2 diabetes?
Of the nearly 16 million Americans with diabetes, 90-95% (14.9 million) have Type-2 diabetes.
Type-2 diabetes results when insulin production is defective and tissue resistance to
insulin develops. For many persons with Type-2 diabetes, daily insulin supplementation is not required.
Diabetes is managed by making moderate changes in diet and exercise.
