Obesity

Alternative Names

Morbid obesity; Fat - obese

Treatment

A combination of calorie restriction and exercise (when adhered to) appears to be more effective rather than either one alone. Sticking to a weight reduction program is difficult and requires a lot of support from family and friends.

Even modest weight loss can improve your health. It is important to work with your health care provider or dietician to develop a plan that is best for you. For most people, weight can be lost by eating a healthier diet, exercising more, and adopting new behaviors such as keeping a food diary, avoiding food triggers, and thinking positively.

There are many over-the-counter diet products. Most do not work and some can be dangerous. Before using one, talk to your health care provider.

Prescription weight loss drugs are available. Such medicines include subutramine (Meridia) and orlistat (Xenical). Ask your health care provider if these are right for you.

Surgery may be an option for persons who are morbidly obese and who cannot lose weight using other methods. Weight loss surgery, such as placing adjustable bands around the stomach and gastric bypass surgery, can significantly improve weight and health in the right candidate. Talk to your doctor to learn if this is a good option for you.

Support Groups

Many people find it easier to follow a diet and exercise program if they join a group of people with similar problems.

Possible Complications

Medical problems commonly resulting from untreated obesity and morbid obesity include:

• Diabetes
• Hypertension
• Heart disease
• Stroke
• Certain cancers, including breast and colon
• Depression
• Osteoarthritis

Obesity can lead to a gradual decrease in the level of oxygen in your blood, a condition called hypoxemia. Persons who are obese may temporarily stop breathing while asleep (sleep apnea). Decreased blood oxygen levels and sleep apnea may cause a person to feel sleepy during the day. The conditions may also lead to high blood pressure and pulmonary hypertension. In extreme cases, especially when left untreated, this can lead to right-sided heart failure and ultimately death.

When to Contact a Medical Professional

Schedule an appointment with your health care provider if you or your child are obese or gaining weight at an extremely rapid rate. Remember that catching the problem early is much simpler than trying to fix it after the person has gained an excessive amount of weight.
