| It is the inability of the body to use glucose for
energy due to inadequate amounts or loss of sensitivity to hormonal insulin. Diabetes
mellitus is a chronic disease in which the body produces little or no insulin or resists
the insulin that it does produce. The mechanism: Insulin transports glucose into the
cells for use as energy and storage as glycogen. It also stimulates protein synthesis and
free fatty acid storage in the fat deposits. When a person lacks sufficient insulin, body
tissues have less access to essential nutrients for fuel and storage. Therefore the unused
glucose accumulate in blood and urine causing excessive urination and thirst.
There are two main forms of diabetes mellitus: Type I or insulin-de-pendent, and
the more prevalent Type II or non-insulin-dependent.
Type I usually occurs before age 30, although it may strike at any age. The person with
this type is usually thin and needs insulin injections and dietary modifications to
control his or her blood sugar level.
Type II usually occurs in obese adults over age 40. It's most often treated with diet
and exercise (possibly in combination with drugs that lower the blood sugar level),
although treatment sometimes includes insulin therapy.
