The Invention That Could End Obesity

Love the enthusiasm..! This does seem too good to be true, and... But it does show how keen the world is to finding a solution to the Obesity epidemic that doesn't mean subjecting people to major surgery.  However, this, I suspect is not it.  Gastric surgery for obesity is still the best (and currently only) way of giving patients significant weight loss experiences with the chance of excellent long term results as well.  That sounds too good to be true also, but in my experience it isn't!  It does require some guidance regarding the right option for Bariatric Surgery (Gastric Banding, Gastric Sleeve and Gastric Bypass) for you and the right support pre-, during and post- surgery.  Don't look any further - we should talk!

A Michigan surgeon invented an apparatus that he believes tricks the brain into thinking the stomach is full. His Full Sense Device could be a lifesaver for millions of obese Americans and raises questions about how hunger — our most basic human impulse — even works.

Bonnie Lauria was miserable. She was subsisting on liquids and a handful of foods her stomach could handle. Ever since she’d undergone gastric bypass surgery in the ’80s, foods like meat and bread that went down her throat in a lump would come right back up. “I knew where every bathroom was in every restaurant in the state,” Lauria says from her home in West Branch, Michigan. “It was horrendous.”

During gastric bypass surgery, the stomach is reduced to about the size of a walnut and attached to the middle of the small intestine. Lauria’s complications from the surgery weren’t normal, so she went under the knife a second time. Still, her condition didn’t change. She switched doctors several times, but no one could help. Eventually, someone recommended bariatric surgeon Dr. Randy Baker in Grand Rapids in 2004.

Baker ran some tests and saw that the spot where Lauria’s walnut-size pouch met her small bowel was tightening. Previous doctors had tried to widen the passage so that food could pass through, but the stricture had returned. Complicating Lauria’s condition were those multiple surgeries, which left so much scar tissue that operating again would be too difficult and too dangerous.

Baker was at a loss. Then he started thinking about esophageal stents. Just like a coronary stent keeps an artery open, an esophageal stent holds the esophagus open and is often used in patients who have difficulty swallowing. What if one of those could prop open the small bowel too?

As far as Baker knew, no one had ever attempted a procedure like that before. But Lauria was out of options, so Baker told her his strategy. She agreed; he inserted the stent and hoped for the best.

“She came back to my office two weeks later and said, ‘Dr. Baker, I’m feeling great. I can eat sloppy Joes!’” Baker says. “Here’s a lady who could only do liquids, and now she can eat solids. And she’s losing weight.”

Lauria didn’t have an explanation; she told Baker she simply wasn’t hungry anymore. Baker wondered if he and other bariatric surgeons had been going at it all wrong. The stent, he theorized, was putting pressure at the top of Lauria’s pouch and sending signals to her brain saying, “I’m full.” It was doing what food does, but without actual food. Which raised some questions: What if we don’t need invasive surgeries that cut away portions of the stomach and rearrange the digestive tract and intestines? What if all we need is a device that puts pressure near the top of the stomach?

Baker set out to test his hypothesis, teaming up with a former product specialist from W.L. Gore (creators of Gore-Tex) and two surgeons at his Grand Rapids practice to create the Full Sense Device — a nitinol wire-mesh funnel coated in silicone that can be inserted through the mouth and placed in less than 10 minutes. Current plans would allow the device to remain for up to six months before removal, though in the future that time may be longer. In the company’s trials, every patient implanted with the device lost weight and continued to lose weight until the device was removed. Baker calls the phenomenon “implied satiety.” At six months, average patients lost 75% of their excess body weight — significantly more and at a faster rate than any bariatric procedure, and all, Baker says, with no “severe adverse side effects.”

The Institute for Health Metrics and Evaluation estimates that 160 million Americans — nearly half — are overweight as indicated by their body mass index, which is calculated from a person’s height and weight. (A BMI between 25 and 29.9 is considered overweight; 30-plus is obese.) Of those people, 24 million are estimated to be morbidly obese, meaning they have a BMI over 40 and are at higher risk for serious, life-threatening illnesses, including heart disease, diabetes, degenerative arthritis, and cancer. Bariatric surgeries can and often do lead to impressive weight loss, yet only 1% of obese Americans opts for the invasive and costly procedure — usually $20,000 to $30,000. (Rex Ryan, Roseanne Barr, Carnie Wilson, Al Roker, Chris Christie, Randy Jackson, and Star Jones are reported to be among the 1%.)

“There are a bunch of things that contribute to that,” says Randy Seeley, an obesity researcher and professor of surgery at the University of Michigan. “One is the ick factor — ‘someone is going to chop up my GI tract.’ Some of it is cost — it’s still not universally covered. Third is stigma. The implication is that it’s the easy way out — you’re cheating somehow by taking that option — which goes to our societal biases about obesity.”

Dr. Baker has come up with a nonsurgical device that he says will enable obese patients to lose substantial weight, and at a fraction of the cost of surgery — in the neighborhood of $5,000 at an outpatient center. A company claiming to have found a simple solution to drastic, easy weight loss is, of course, nothing new; in fact, it’s big business. (See: late-night infomercials.) Some surgeons and researchers are skeptical of Baker’s pressure theory, and at least one patient experienced chronic acid reflux after the device was inserted. But more than 10 years after the eureka moment, Baker is hopeful that doctors in Europe could begin using the Full Sense Device this year and in Canada and Mexico soon after. Americans will have to wait longer; Food and Drug Administration approval is unpredictable and likely still years away. Baker’s concern, though, is that the Full Sense Device might work too well. If it’s effective, easy, and cheap, what’s to stop people from abusing it?

“When this hits the market, there’s not going to be just 10,000 to 15,000 people having it,” says Fred Walburn, president and sole employee of Full Sense Device’s parent company, BFKW. “There’s going to be hundreds of thousands. Millions per year.”

For diabetes in obesity, weight-loss surgery beats medication

For diabetes in obesity, weight-loss surgery beats medication

This truly is a remarkable study, as Dr Schauer says. It is as close as you can get to answering a scientific question with the use of a study. The question being, does Bariatric surgery cure diabetes? Whilst cure is a very strong word, this 5year data gives a very powerful indication that surgery is able to alter the course of diabetes significantly and over the longer term. This is big news and should definitely be suggested to people who develop type 2diabetes with increasing weight. Worth a visit to your GP to discuss whether bariatric surgery is right for you!


Half of the patients treated with weight-loss surgery in the study were diabetes-free at five years, said Dr. Francesco Rubino of Kings College London in the UK and colleagues in a report in The Lancet.

“The five-year mark is an important mark in many diseases,” Dr. Rubino told Reuters Health by phone. “The fact that some patients at five years are basically disease-free is a remarkable finding.”

In 2009, he and his colleagues randomly assigned 20 obese patients with type 2 diabetes to receive medical treatment, 20 to receive a type of weight-loss surgery called a gastric bypass, and another 20 to undergo a weight-loss operation called a biliopancreatic diversion.

Eighty percent of patients who had surgery had their blood sugar under good long-term control, versus about 25 percent of patients treated with drugs only.

All of the study groups had a reduction in cardiovascular risk. But the surgery-treated patients had a 50 percent lower risk of heart and blood vessel disease than those treated with drugs only, and they needed fewer drugs for treating high blood pressure or high cholesterol.

The improvements in blood sugar control and heart disease risk weren’t related to how much weight patients lost.

“What really is causing the remission of diabetes after surgery remains mysterious,” Dr. Rubino said. What is known, he added, is that the intestines produce a host of hormones involved in regulating metabolism. Reconstructing the gastrointestinal tract so that food bypasses the stomach and small intestine may help restore normal metabolic control, he explained.

Like any surgery, weight loss operations carry risks. An international study published earlier this, for example, found that after two years, people randomized to have gastric bypass surgery had better control of their type 2 diabetes than people assigned to a medication group, but they also had a higher risk for infections and bone fractures. (See Reuters Health story of May 21, 2015.)

And some patients may gain back some of the weight they lost.

Still, doctors are increasingly referring to this type of surgery as “diabetes surgery,” rather than obesity surgery, said Dr. Philip Schauer, the director of the Cleveland Clinic Bariatric and Metabolic Institute and a bariatric surgeon, in a telephone interview with Reuters Health. Dr. Schauer did not participate in the new study.

There are some people, this study shows, that can go into remission for up to five years or more,” he said. “We hesitate to use the word ‘cure,’ but it’s pretty darn close to a cure, about as close to a cure as you can get.’

Dr. Schauer pointed out that about half of patients with type 2 diabetes are unable to control their blood sugar with medication and lifestyle measures. Based on the new findings, he said, bariatric surgery should be offered to these patients if they are moderately obese, for example with a body mass index (BMI) of 35. (BMI is a measure of weight in relation to height.)

Currently the National Institutes of Health states that patients should have a BMI of 40, or a BMI of 35 with obesity-related illness, such as type 2 diabetes, in order to be eligible for weight loss surgery.

“There are still many insurance companies today that will not pay for this surgery for any reason, whether it’s for obesity or diabetes. It means that they are denying people effective treatment,” Dr. Schauer said. “This study is going to make insurance carriers and third party payers rethink their coverage policies regarding bariatric or diabetes surgery, as we prefer to call it.”

Bariatric surgery aids joint replacement outcomes

Bariatric surgery aids joint replacement outcomes

Hi All,

Joint replacement surgery is common and obesity is common and obesity is a known risk factor for Osteoarthritis of the weight bearing joints.  This study asks the question whether Bariatric surgery (including Gastric Bypass, Sleeve Gastrectomy or Gastric Banding) to help patients to lose significant amounts of weight before undergoing orthopedic surgery has any cost effectiveness associated with it.  Obviously public hospitals are most interested in the bottom line of healthcare costs, along with good outcomes for the patients.  There are a lot of examples where spending more money up front results in spending less money over the longer term.  These sorts of studies are critical in putting that theory to the test.  It is hard to convince the financial bods in public hospitals to do more bariatric surgery with the promise of saving more long term unless you have the evidence to back up your claims.  But this is one of those situations that performing Bariatric surgery in the first instance may mean fewer patients going on to need joint replacements or  better outcomes for those that do have their orthopedic surgery 2 years later and ultimately saving the Public Health System money overall.  This is an intelligent way to approach a medical dilemma and looks at treating the whole person and their medical issues rather than just focussing on the joint that needs replacing.  I like it!



Two studies at Hospital for Special Surgery (HSS) in New York City have found that bariatric surgery prior to joint replacement is a cost-effective option to improve outcomes after hip or knee replacement. The papers, ‘Cost-Effectiveness of Bariatric Surgery Prior to Total Knee Arthroplasty in the Morbidly Obese’ and ‘Cost-Effectiveness of Bariatric Surgery Prior to Total Hip Arthroplasty in Morbidly Obese Patients’ were presented at the annual meeting of the American Academy of Orthopaedic Surgeons in Las Vegas.

"Up to 50 percent of hip replacements are performed in obese patients at some institutions," said Dr Emily Dodwell, an orthopaedic surgeon at HSS and lead investigator. "Obesity is associated with longer hospital stays, higher overall costs and higher failure rates, necessitating costly revision surgery."

It is well-known that obesity takes a toll on one's health. Bariatric surgery and subsequent weight loss reduces the risk of heart disease, diabetes and even some forms of cancer. But the effect of bariatric surgery on joint replacement outcomes was not known, and the HSS investigators set out to determine the costs and benefits of weight-loss surgery prior to knee replacement and the costs and benefits before hip replacement.

"We know that bariatric surgery is a cost-effective intervention for morbid obesity," said Dr Alexander McLawhorn, a chief orthopaedic surgery resident at HSS and study author. "Yet, the cost-effectiveness of bariatric surgery to achieve weight loss prior to joint replacement and thus decrease the associated complications and costs in morbidly obese patients was unknown."

Investigators used a software program to compare the cost-utility of two treatment protocols for patients who were considered morbidly obese and had advanced knee or hip osteoarthritis. One group had joint replacement immediately, without losing weight. The other group had bariatric surgery, followed by hip or knee replacement two years later. Patients typically lose weight during this time period.

Study patients had a BMI 40 or a BMI>35 and at least one other serious obesity-related health problem. For study purposes, researchers assumed that at least one-third of patients having bariatric surgery lost their excess weight prior to undergoing joint replacement.

"Our findings indicate that surgical weight loss prior to joint replacement is likely a cost-effective option from a public payer standpoint in order to improve outcomes in obese patients who are candidates for joint replacement," said Dodwell. "Some health care systems do not include weight loss surgery as a covered benefit, and it is possible that studies such as this will be helpful in re-evaluating whether weight loss surgery may be a reasonable covered benefit."

McLawhorn noted that for some patients experiencing severe knee or hip pain, it may be impractical to hold off on joint replacement. He adds that many times, an orthopaedic surgeon is the first doctor such a patient sees for arthritis pain.

"Ideally, a team approach would be used to treat morbidly obese patients with hip and knee arthritis in which various health care professionals are in place to help a patient lose weight, improve his or her health, and optimise nutrition before joint replacement to maximize its benefits," he said.
