Q: I am five feet tall and 100 pounds overweight. My doctor says if I lost weight, my weakness and fatigue would go away. I have tried to diet and just can't lose weight. Is it safe for polio survivors to have their stomachs stapled?
To be a candidate for stomach stapling, which is technically called gastric bypass, your body mass index must be 40 or more. (BMI equals weight in pounds times 703, divided by height in inches, divided again by height.) A "normal" BMI is up to 25. "Overweight" is 25 to 30 and "obese" is 30 and above. At 5 feet tall and 210 pounds, your BMI is 41, which means you are a candidate for gastric bypass.
There are two gastric bypass procedures. In one, staples are used to divide your stomach into two compartments--a small egg-sized upper "pouch" to hold food and a larger unused bottom section. Your small intestine is connected to the small pouch, which limits how much you can eat at a sitting and thereby enforces a "diet."
In a less common procedure called gastric banding, the "pouch" is created using bands or staples. A narrow passage is left so that food can still pass through the remainder of the stomach and into the small intestine. This procedure is not as successful for weight loss but is better when it comes to absorption of vitamins and minerals.
Surgeries are performed under anesthesia either laporoscopically or the old-fashioned way, which is more painful and can cause stomach muscle weakness. If you weigh more than 350 pounds or if you have had abdominal surgery in the past, you are probably not a good candidate for laporoscopy. Both procedures carry with them all of the post-polio surgical and anesthesia concerns (see "Preventing Surgical Complications" in The Post-Polio Library at postpolioinfo.com/postpolio). And there are also unique side effects: infection, bleeding, diarrhea, bloating, vomiting, and iron and calcium deficiencies causing anemia or osteoporosis.
What's more, if you couldn't stick to the post-polio "diet," it may be hard to eat only a few ounces of food many times a day--a requirement since your new mini-stomach will only hold about a tablespoonful at first. But all this said, the procedures typically result in a weight loss of about 10 pounds per month for up to two years--an average loss of 60 percent of the excess weight--with most weight lost right after surgery when you're only taking liquids. In addition, a recent review of 136 studies of 22,000 obese gastric bypass patients found that dangerous medical conditions could be eliminated by the surgery: High blood pressure was reduced in 62 percent of patients, diabetes disappeared in 77 percent, and sleep apnea vanished in 86 percent. Cholesterol improved in at least 70 percent.
But is gastric bypass safe for polio survivors? A medical journal article found that gastric bypass was safe and effective in two people with post-polio and in a few people with multiple sclerosis, cerebral palsy and stroke. Two Post-Polio Institute patients have had gastric bypass, stuck to their diets, lost weight without exercise, and now feel, function and look great.
Although gastric bypass is the last resort for the treatment of severe and dangerous obesity--and should never be done to treat post-polio muscle weakness or fatigue--polio survivors can do well after having their stomachs stapled.
