NASHVILLE — A recent study published in JAMA shows that bariatric surgery is associated with a 32% decrease in the risk of obesity-related cancers and a 48% decrease in the risk of cancer-related deaths among adults with obesity. As the bariatric surgery program at TriStar Southern Hills grows, Dr. Patrick Davis says the surgery is providing a more accessible avenue for adults with obesity to create a healthier life.

“Carrying that much weight on your body creates a lot of stress from your joints, to your immune system and your cardiovascular system,” said Dr. Davis. “These are the biggest associated factors with not only cancer but with obesity-related conditions, including diabetes and sleep apnea.”

The CDC states that more than 684,000 obesity-associated cancers occur in the United States each year and the number of states in which at least 35% of residents have obesity has nearly doubled since 2018. These include many Southern states, including Alabama, Arkansas, Kentucky, Mississippi and Tennessee.

According to the study, not only did individuals who underwent bariatric surgery have a lower rate of cancer and cancer-related death but they also weighed, on average, 54.7 pounds less than those who did not undergo bariatric surgery. The study also states that bariatric surgery is the most effective, currently available treatment for obesity. Patients typically lose 20% to 35% of body weight after surgery, which is often sustained for many years.

“In the year after surgery, patients will come into my office, sometimes almost hard to recognize, and are just ecstatic with where they are in life. They’re able to do something they haven't done in years, if ever before. Whether that's going hiking, running a 5K, or no longer needing their CPAP machine. There's nothing more rewarding in my job than those visits,” said Dr. Davis.
