Are You Overweight? |
Use the
weight-for-height chart below to see if you are overweight. Find
your height in the left-hand column and move across the row to find
your weight. If your weight falls within the moderate to severe
overweight range on the chart, you are more likely to have health
problems. Weights above the healthy weight range are less healthy
for most people.

What Is Your Waist Measurement? |
If you are a woman and your waist measures more than 35 inches, or
if you are a man and your waist measures more than 40 inches, you
are more likely to develop heart disease, high blood pressure,
diabetes, and certain cancers. You may want to talk to your doctor
or other health professional about the health risks of your weight.

What Are the Risks to Your Health of Being Overweight? |
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. 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 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.

How You Can Lower Your Health Risks |
If you are overweight, losing as
little as 5 to 10 percent of your body weight may improve many of
the problems linked to being overweight, such as high blood
pressure and diabetes. For example, if you weigh 200 pounds and are
considered overweight on the weight-for-height
chart, you would need to lose 10 to 20 pounds. Even a small
weight loss can improve your health.
Slow and steady weight loss of no more than 1 pound per week is the safest way to lose weight. Very rapid weight loss can cause you to lose muscle rather than fat. It also increases your chances of developing other problems, such as gallstones, gout, and nutrient deficiencies. Making long-term changes in your eating and physical activity habits is the best way to lose weight and keep it off over time.

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.
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
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.
Whether you are trying to lose weight or maintain your weight,
you should take a look at your eating habits and try to improve
them. 
Try to eat a variety of foods, especially pasta, rice, bread,
and other whole-grain foods. You should also eat plenty of
fruits and vegetables. These foods will fill you up and are
lower in calories than foods full of oils or fats.
For
more information on healthy eating, see the
Spend
less time in activities that use little energy like watching
television and playing video games and more time in physical
activities. Try to do at least 30 minutes of physical activity
a day on most days of the week. The activity does not have to
be done all at once. It can be done in short spurts--10 minutes
here, 20 minutes there--as long as it adds up to 30 minutes a
day. Simple ways to become more physically active include
walking to the store or taking the stairs instead of the
elevator. See WIN's fact sheet
