Who
has Diabetes?
1
An estimated 16 million Americans have diabetes, and about one-third
of them are unaware of it. About 1,700 new cases are diagnosed every
day in the United States. The seventh leading cause of death among
Americans, diabetes is the leading cause of new cases of blindness,
kidney failure, and lower extremity amputations, and it greatly increases
a person's risk for heart attack or stroke.
There
are four types of Diabetes
2
Type 1 diabetes mellitus requires
the injection of insulin throughout life, daily monitoring of blood
sugar (glucose) levels, and adjustments in diet and other aspects
of daily living. As a result, insulin therapy must be rigorously managed.
About half of patients with Type 1 diabetes develop the disease before
age 18. At least one in every 300 children in the United States develops
this disease.
Type 2 diabetes, previously called
non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes,
may account for about 90 to 95 percent of all diagnosed cases of diabetes.
In type 2 diabetes, the pancreas makes some insulin, but it is not
enough and/or the body's cells do not use it correctly because of
insulin resistance. Risk factors for type 2 diabetes include older
age, obesity, family history of diabetes, prior history of gestational
diabetes, impaired glucose tolerance, physical inactivity, and race/ethnicity.
Both type 1 and type 2 diabetes can cause many complications, including
blindness, vascular disease, kidney failure and peripheral vascular
disease, which can decrease circulation and sometimes require the
amputation of limbs. In addition, a person with diabetes can experience
life-threatening reactions to low blood sugar as well as extremely
high glucose.
Gestational Diabetes Between 2
and 5 percent of pregnant women in the United States develop gestational
diabetes. Obesity is also associated with higher risk. Women who have
had gestational diabetes are at increased risk for later developing
type 2 diabetes. In some studies, nearly 40 percent of women with
a history of gestational diabetes developed diabetes in the future.
'Other Specific
Types' of
Diabetes result from specific genetic syndromes, surgery, drugs, malnutrition,
infections, and other illnesses. Such types of diabetes may account
for 1 to 2 percent of all diagnosed cases of diabetes.

What
is Diabetes?
1
Diabetes means your blood sugar is too high. Your blood always has
some sugar in it because you need sugar for energy to keep you going.
But too much sugar in the blood is not good for your health. People
with diabetes have either a shortage of insulin or a decreased ability
to use insulin, a hormone secreted by the pancreas. Insulin allows
glucose (sugar) to enter cells and be converted to energy. In uncontrolled
diabetes, glucose and fats remain in the blood and, over time, can
cause serious damage to the heart, eyes, kidneys, nerves, and blood
vessels.

How
do you know if you have Diabetes
Anyone 45 years old or older
should consider getting tested for diabetes. If you are 45 or older
and your BMI indicates that you are overweight, it is strongly recommended
that you get tested1

There
are three ways to diagnose diabetes and each must be confirmed on
a subsequent day:
1.
Fasting blood sugar (FBS) is 126 mg/dl or more on two occasions.
Fasting is defined as no caloric intake for at least 8 hours.
2. 2 hour glucose tolerance test of 200 mg/dl or more.
3. Symptoms of diabetes plus a casual plasma glucose 200.
Casual is defined as any time of day without regard to time since
last meal. The classic symptoms˛ of diabetes include increased urination,
increased thirst, and unexplained weight loss.

Major
Risk
Factors for Diabetes
1
If you have one or more of the following risk factors, testing should
be considered younger than 45 years old or more often than every
3 years:
|
|
Family history: having a mother, father, sister or brother with
diabetes |
|
|
Obesity: = 120% desirable weight or a BMI = 27 kg/M2 |
|
|
Ethnicity:
African American, Hispanic-American, Native-American, Asian-American,
Pacific Islander have a greater risk of diabetes. |
|
|
If a mom has had a history of gestational diabetes (pregnancy
related diabetes), or delivery of a baby weighing 9 lbs. |
|
|
Elevated Blood Pressure Hypertension = 140/90. |
|
|
Elevated
HDL cholesterol level = 35 mg/dl and/or triglyceride level
= 250 mg/dl. |
|
|
On
previous testing, had IGT (impaired glucose tolerance) or IFG
(impaired fasting glucose). |
