Desperate measures: For 45,000 obese Americans each year, weight-loss surgery is truly a lifesaver. The pounds drop away, along with risks of killer diseases. What any woman thinking about the operation should know - Weight-Loss Surgery: The Facts
Even before the baby, 32-year-old Robin Williams was heavy. “Not obese,” she says, “but definitely overweight.” When she gained 80 pounds during a pregnancy in 1991, Williams, a railroad safety manager in Bossier City, La., figured she could slim down later. After the baby was born, she tried numerous fad diets and exercised with coworkers on her lunch break. But because the diets — such as one “grapefruit diet” — were so difficult to follow for long (not to mention unhealthy), she always reverted to her old habits. “I would lose 10 pounds in three months, but then gain it back in one or two weeks,” she says. In 1997, she became pregnant again and gained 12 more pounds, followed by an additional 20 postpartum. Reaching 245 pounds at 5 feet 2 inches by age 30, Williams had become clinically obese and was at high risk for complications such as heart disease and diabetes. Now she was dieting not just to look better, but to ease increasingly high blood pressure and chronic leg and back pain. Nothing worked.
“Then I ran into a friend who’d had weight-loss surgery,” Williams says. “I was shocked. She had lost 105 pounds.” Williams immediately explored surgery for herself. News reports about singer Carnie Wilson’s successful weight-loss surgery fueled her interest. Still, Williams was cautious. “The first doctor I saw gave me a canned speech. I didn’t get a chance to ask questions,” she says. “I felt like I was being herded into surgery.” After consulting a second doctor, who answered all her questions, she decided to undergo gastric bypass, a common weight-loss, or bariatric, surgical procedure. The operation went smoothly, and Williams lost 115 pounds, most of it within a year. “I never dreamed I’d now be in a size 6,” she says.
The appeal of a quick and permanent solution - is, in many ways, typical. So is her course of action: Bariatric surgeons now perform about 45,000 operations annually, 85 percent of them on women. The number is up dramatically from several years ago, says Kenneth Jones Jr., M.D., president of the American Society for Bariatric Surgery (ASBS), an educational professional association whose membership has doubled in four years. But it’s not just prevalent obesity and high-profile cheer-leading that are driving these numbers. Also, new techniques are allowing operations to be done as laparoscopic “keyhole” procedures, which don’t require the large abdominal incision necessary in standard operations. For skilled surgeons who are flocking to this market, weight-loss procedures are relatively easy to learn and extremely lucrative. Operations can run from $14,000 to around $50,000 and are often (but not always) covered by insurance.
Alarmed by this double-edged enthusiasm from patients and doctors, some observers fear that women might be steered into inappropriate procedures or suffer serious complications. “There’s concern that a lot of surgeons are getting into this who don’t have enough experience in bariatric care, especially when it comes to managing complications,” says Harvey Sugerman, M.D., professor of surgery at Virginia Commonwealth University in Richmond.
Meals: one ounce at a time
It’s easy to see why side effects are a major concern with weight-loss surgery: They’re part of the package even when things go well. Every form of bariatric surgery fundamentally alters the way the gastrointestinal system works. Though the operations can be reversed (often with difficulty), the gut will never be the same. In the most common operation, vertical banded gastroplasty, surgeons use a special band and staples to crimp the upper stomach into a small pouch and narrow the outlet to the small intestine. This lets only an ounce or two of food enter the stomach at a time, significantly cutting calorie intake. Increasingly, doctors combine gastroplasty with a bypass in which stomach contents are detoured around the leading sections of the small intestine, where much of the breakdown and absorption of food takes place. Without full absorption, the body can’t add pounds easily.
People who have had a gastric bypass can suffer a range of nutritional deficiencies (especially of calcium, iron and vitamin B2), leading to conditions such as osteoporosis and anemia. While these effects can be tamed at a doctor’s behest with nutritional supplements, other effects must simply be tolerated. One of the most common is “dumping syndrome,” in which the stomach contents that move too swiftly through the small intestine cause nausea, sweating, weakness and diarrhea. “If I eat just one bite too much, I get this nauseated, clammy, icky feeling,” Williams says. Gastroplasty alone can cause vomiting when even tiny amounts of food stretch the stapled stomach.
The body adapts to such effects and patients become slightly more tolerant of food over time. In fact, about 10 percent of patients can eventually “outeat” the procedure with high-calorie food, losing less than half their excess weight, which is how surgeons define failure, according to Jones. (Because it’s possible to boost caloric intake, especially after a year or two, women who’ve had surgery can have healthy pregnancies.) But whether surgery ultimately produces successful results, “these procedures permanently change the way you eat,” says Edward Livingston, M.D., director of the bariatric-surgery program at the University of California, Los Angeles, School of Medicine.
If you are a candidate and determined to pursue surgery, the issue becomes finding a doctor who has the skill, experience and hospital resources to do the operation well and, just as important, follow through with post-op care. “Personally, I’d stay away from for-profit organizations that advertise their services,” Livingston says. “If they’re selling operations like a car dealer, they may not always have your best interests in mind.” Big hospitals that get other doctors’ most difficult referrals are most likely to have high-quality, specialized staff and equipment, he says. Ask a prospective surgeon to put you in touch with former patients who’ve had complications. “If he’s not willing to do that, he has something to hide,” Livingston says. Likewise, ask him what his complication and mortality rates are for bariatric cases, and put them in context. For example, does he tend to accept patients who are heavier or sicker than do other doctors you’re considering? If so, he may be an excellent surgeon, but you ca n expect his complication and death rates to be higher. Also inquire about special equipment and hospital staff available to meet the needs of obese patients, especially respiration experts in the recovery and intensive care units. Look up your doctor on the ASBS Web site (asbs.org). If he’s listed as a regular member, he’s broadly certified by the American Board of Surgery (there’s no special certification for bariatric surgeons). If he’s an “affiliate” member, he’s not yet board-certified.
Talk to your doctor in detail about life after the operation. He should make clear that surgery won’t let you eat however much you want. In fact, because your eating will be severely restricted, you’ll pay more attention to your food intake than ever before. “For the best long-term results, I still recommend eating a lowfat diet of fruits and vegetables, and exercising moderately three to four times a week,” Jones says. In Williams’ experience, however, dedication to results becomes easier when you’re thin. “My confidence level has increased 200 percent,” she says. “My work life, sex life and social life have all seen tremendous improvements, and I’m glad every day that I had the surgery. The small sacrifices, like eating smaller portions and limiting the types of foods that I eat are well worth it. I look and feel good, and I want to stay that way.”

“As a thin guy, I could be objective about a subject [weight-loss surgery] that can provoke strong feelings in doctors and patients,” says Richard Laliberte, author of “Desperate Measures” on page 94. Keeping fit for Laliberte means having fun - specifically, cycling the country roads near his home in Eastern Pennsylvania. “The roads are so hilly they have become a training mecca for cyclists from all over the world,” says Laliberte, who also contributes to Maxim and Parents.
