Bypass and gastric banding, Oz said, also could cure or control sleep apnea, asthma, reflux, infertility, low back pain and osteoarthritis.
Gastric bypass surgery changes how your stomach and small intestine process the food you eat by making your stomach smaller, making you feel fuller with less food.
With banding, a surgeon places a band around the upper part of your stomach and creates a small pouch that limits how much food you can eat and makes you feel fuller sooner after eating small amounts.
The band can later be adjusted by your doctor so that food can pass slowly or faster through the digestive system.
The surgery is minimally invasive and patients generally are hospitalized one or two days, depending on the type of operation they undergo, Jean-Pierre said in a YouTube video that summarized the process.
“On average, most patients stay out of work about a week or two weeks. It’s really sort of just to get accustomed to the new lifestyles changes, as far as learning how to eat or drink all over again,” Jean-Pierre said.
“I think it’s quite courageous for patients to come in and want to do something about their morbid obesity.”
