| Heart
Disease and Stroke
Heart
disease and stroke are the leading causes of death and disability
for both men and women in the United States. Overweight people
are more likely to have high blood pressure, a major risk
factor for heart disease and stroke, than people who are not
overweight. Very high blood levels of cholesterol and triglycerides
(blood fats) can also lead to heart disease and often are
linked to being overweight. Being overweight also contributes
to angina (chest pain caused by decreased oxygen to the heart)
and sudden death from heart disease or stroke without any
signs or symptoms.
The
good news is that losing a small amount of weight can reduce
your chances of developing heart disease or a stroke. Reducing
your weight by 10 percent can decrease your chance of developing
heart disease by improving how your heart works, blood pressure,
and levels of blood cholesterol and triglycerides.
Diabetes
Noninsulin-dependent
diabetes mellitus (Type 2 diabetes) is the most common type
of diabetes in the United States. Type 2 diabetes reduces
your body's ability to control your blood sugar. It is a major
cause of early death, heart disease, kidney disease, stroke,
and blindness. Overweight people are twice as likely to develop
Type 2 diabetes as people who are not overweight. You can
reduce your risk of developing this type of diabetes by losing
weight and by increasing your physical activity.
If
you have Type 2 diabetes, losing weight and becoming more
physically active can help control your blood sugar levels.
If you use medicine to control your blood sugar, weight loss
and physical activity may make it possible for your doctor
to decrease the amount of medication you need.
Cancer
Several
types of cancer are associated with being overweight. In women,
these include cancer of the uterus, gallbladder, cervix, ovary,
breast, and colon. Overweight men are at greater risk for
developing cancer of the colon, rectum, and prostate. For
some types of cancer, such as colon or breast, it is not clear
whether the increased risk is due to the extra weight or to
a high-fat and high-calorie diet.
Sleep
Apnea
Sleep
apnea is a serious condition that is closely associated with
being overweight. Sleep apnea can cause a person to stop breathing
for short periods during sleep and to snore heavily. Sleep
apnea may cause daytime sleepiness and even heart failure.
The risk for sleep apnea increases with higher body weights.
Weight loss usually improves sleep apnea.
Osteoarthritis
Osteoarthritis
is a common joint disorder that most often affects the joints
in your knees, hips, and lower back. Extra weight appears
to increase the risk of osteoarthritis by placing extra pressure
on these joints and wearing away the cartilage (tissue that
cushions the joints) that normally protects them. Weight loss
can decrease stress on the knees, hips, and lower back and
may improve the symptoms of osteoarthritis.
Gout
Gout
is a joint disease caused by high levels of uric acid in the
blood. Uric acid sometimes forms into solid stone or crystal
masses that become deposited in the joints. Gout is more common
in overweight people and the risk of developing the disorder
increases with higher body weights.
Note:
Over the short term, some diets may lead to an
attack of gout in people who have high levels of uric acid
or who have had gout before. If you have a history of gout,
check with your doctor or other health professional before
trying to lose weight.
Gallbladder
Disease
Gallbladder
disease and gallstones are more common if you are overweight.
Your risk of disease increases as your weight increases. It
is not clear how being overweight may cause gallbladder disease.
Weight
loss itself, particularly rapid weight loss or loss of a large
amount of weight, can actually increase your chances of developing
gallstones. Modest, slow weight loss of about 1 pound a week
is less likely to cause gallstones.
