Obesity, Excess Weight and Gastric SurgeryGastric Surgery for ObesistySevere obesity is a chronic condition that is very difficult to treat. Gastric surgery [e.g. stomach by-pass, stomach stapling, lap band, or stomach balloon] to promote weight loss by restricting food intake or interrupting digestive processes is an option for severely obese people. A body mass index (BMI) above 40 - which means about 100 pounds of overweight for men and about 80 pounds for women - indicates that a person is severely obese and therefore a candidate for surgery. Surgery also may be an option for people with a BMI between 35 and 40 who suffer from life-threatening cardiopulmonary problems (for example, severe sleep apnea or obesity-related heart disease) or diabetes. However, as in other treatments for obesity, successful results depend mainly on motivation and behavior. More About Severe OverweightCauses
