Obesity is a disease affecting more than 72 million Americans. In Wyoming, 37 percent of adults are classified as overweight and 28 percent of adults are obese. Obesity is caused by a variety of environmental, genetic and metabolic factors. When non-surgical weight-loss efforts have failed, consultation with a bariatric surgeon may be beneficial. Multiple surgical options exist and no one single operation is perfect for everyone. See if you qualify for surgery and which types are available. Your bariatric surgeon will discuss each option with you individually to find the best treatment.
