Most Common Surgical Treatments for Clinically Severe Obesity

The obesity epidemic continues to grow in our country, and with obesity comes a whole host of additional health risks, like type 2 diabetes, heart disease, high blood pressure, osteoarthritis and stroke. Those looking to reduce these obesity-related health risks are turning to bariatric or medical weight-loss surgeries like gastric bypass.

With weight-loss surgery, your surgeon makes changes to your stomach or small intestine, or both. The procedure resolves diabetes 80 percent of the time, and patients lose an average of 70 percent of extra weight. However, gastric bypass isn’t the only choice. Learn about your options:

Laparoscopic Adjustable Gastric Band – The surgeon puts a small band around the top of your stomach. The band has a small balloon inside it that controls how tight or loose the band is. The band limits how much food can go into your stomach. This surgery is done using a laparoscope. Advantages include:

  • Minimally invasive with small incisions
  • Short hospital stay
  • Adjustable without additional surgery
  • Can support pregnancy
  • Removable at any time

Laparoscopic Gastric Sleeve – This surgery removes most of the stomach and leaves only a narrow section of the upper part of the stomach, called a gastric sleeve. The surgery may also curb the hunger hormone ghrelin, so you eat less. Advantages include:

  • No cutting, bypassing, or stapling of the intestine
  • Little concern about vitamin and calcium absorption
  • No adjustments or artificial devices put into place
  • Most foods are possible

Laparoscopic Roux-en-Y Gastric Bypass Surgery – The surgeon leaves only a very small part of the stomach (called the pouch). That pouch can’t hold a lot of food, so you eat less. The food you eat bypasses the rest of the stomach, going straight from the pouch to your small intestine. This surgery can often be done through several small incisions using a camera to see inside (laparoscope). Doctors can also perform a mini-gastric bypass, which is a similar procedure also done through a laparoscope. Advantages include:

  • Tiny incisions, resulting is less scarring and easier healing
  • Excellent cosmetic result
  • Little pain
  • Few wound complications
  • Fast recovery
  • Short hospital stay
  • Resuming physical activity soon
  • Little risk of hernia formation

Duodenal Switch- This is complicated surgery that removes most of the stomach and uses a gastric sleeve to bypass most of your small intestine. It limits how much you can eat. It also means your body doesn’t get as much of a chance to absorb nutrients from your food, which could mean you don’t get enough of the vitamins and minerals you need. Advantages include:

  • Results in greater weight loss than other methods, i.e. 60 – 70% percent excess weight loss or greater, at 5 year follow up
  • Allows patients to eventually eat near normal meals
  • Reduces the absorption of fat by 70 percent or more
  • Causes favorable changes in gut hormones to reduce appetite and improve satiety
  • Is the most effective against diabetes compared to other methods

What you Need to Know about Protein

You probably know you need to eat protein, but what is it and where exactly do you find it? The answer is – everywhere – if you’re talking about the body. Proteins make up about 42% of the dry weight of our bodies. The protein collagen—which holds our skin, tendons, muscles, and bones together—makes up about a quarter of the body’s total protein. Protein builds, maintains, and replaces the tissues in your body. Your muscles, your organs, and your immune system are made up mostly of protein. All of our cells and even blood are packed with protein molecules.

Proteins, along with fats and carbohydrates, are the macronutrients that form the basis of our diets. Once consumed, some people associate protein only with helping to build muscle, but keep in mind that’s not all it does for us. In our bodies, protein performs a range of duties, from building new cells to regulating metabolism to helping cells communicate. Proteins help shuttle oxygen throughout the body in the form of hemoglobin, as well as build muscle.

When you eat foods that contain protein, the digestive juices in your stomach and intestine go to work. They break down the protein in food into basic units, called amino acids. The amino acids then can be reused to make the proteins your body needs to maintain muscles, bones, blood, and body organs.

Amino acids are the building blocks of proteins. Our DNA directs the body to join various combinations of amino acids into a variety of sequences and three-dimensional shapes for an arsenal of over 2 million different proteins, each serving a unique function. Our bodies can make some of these amino acids, but there are nine that are considered “essential amino acids” because we must consume these through our diet.

Many foods contain protein, but the best sources are:

  • Beef
  • Poultry
  • Fish
  • Eggs
  • dairy products
  • Nuts
  • Seeds
  • legumes like black beans and lentils

While our bodies can store fats and carbohydrates to draw on when needed, we do not have a storage pool of amino acids. We need a fresh source each day in order to build the body proteins we need. If the body is missing a particular amino acid to form the protein it needs, it will pull that amino acid by breaking down existing muscle protein. If we consistently lack certain amino acids we will lose muscle weight, energy and, eventually, fundamental functions.

The amount of protein you need depends on your weight and health. The Recommended Daily Allowance (RDA) for protein for the healthy individual is 0.8 grams of protein per kilogram of body weight or 3 to 4 grams per 10 pounds, and two to three servings of protein-rich food will meet the daily needs of most adults. Athlete’s protein intake recommendations may be higher.

The good news is that you don’t have to eat all the essential amino acids in every meal. As long as you have a variety of protein sources throughout the day, your body will grab what it needs from each meal.

You can look at a food label to find out how many protein grams are in a serving, but if you’re eating a balanced diet, you don’t need to keep track of it. It’s pretty easy to get enough protein.

Weight-loss Surgery Myths – Setting the Record Straight

If you are considering bariatric surgery, you’ve probably heard many of the popular myths. These run the gamut from horror stories to fairy tales. In reality, these procedures are neither as awful nor as fantastic as they’re made out to be. Here are some facts to help set the record straight about weight-loss surgery (WLS).

Myth: All bariatric surgery involves stomach stapling.

  • There are many different types of gastrointestinal procedures for weight loss, some of which reduce the functioning size of the stomach and others that bypass parts of the digestive tract, reducing absorption of calories and nutrients. Different types of surgeries offer different results, and some are more suitable for particular people than others.

Myth: People who get weight-loss surgery don’t have willpower.

  • Many bariatric surgery patients have struggled for years, pushing themselves to extremes to lose weight and keep it off. They understand that surgery is a final option when everything else has failed. The surgery, recovery and lifestyle changes that accompany WLS require both courage and determination on the part of the patient.

Myth:  Bariatric surgery is only for the morbidly obese.

  • Obesity is only one of the criteria that qualify patients for surgery. Overweight patients may also be candidates if they have one or more health problems that might be reduced or alleviated by weight loss such as diabetes, sleep apnea, hypertension, arthritis, and high cholesterol.

Myth: Bariatric surgery is extremely dangerous.

  • Any type of surgery has associated risks, such as complications or even death. However, a number of recent advances have helped to minimize risks. Surgeries are usually done laparoscopically with mini-incisions that result in faster healing, less pain, and less scarring.

Myth: You will finally be skinny after bariatric surgery.

  • Losing just 50% of excess weight and keeping it off is considered a success story. That’s still going to be overweight in the eyes of most people. Plus, your skin isn’t necessarily going to tone up and be free of drooping after weight loss. However, the health benefits in reducing weight-related problems like sleep apnea often occur even in patients who don’t lose all the weight they would like.

Myth: Weight loss from bariatric surgery is permanent.

  • Unfortunately, even this one is not true. In fact, some regain is likely. Part of this is simply the body adjusting and learning to store fat even on a very restricted diet. At other times, a patient’s failure to adhere to the post-surgery lifestyle recommendations plays a role.

Myth: You should only have WLS if you are done having kids.

  • It isn’t safe to get pregnant in the first year or two after bariatric surgery. You simply won’t be getting enough nutrients to support a growing fetus. After you are done losing weight (if you are taking all your supplements and monitoring your health carefully), getting pregnant should be okay. This is something to discuss with your bariatric surgeon.

Myth: After bariatric surgery, you won’t be able to eat anything that tastes good.

  • Patients who undergo gastric bypass may need to avoid very sweet foods because it can cause side effects like dizziness and nausea. Patients who have a duodenal switch typically need to keep fatty foods to a minimum. However, many patients can and do eat their favorite foods after they recover from surgery. They just eat very small portions.

Myth: You can never be far from a bathroom after WLS.

  • In the aftermath of surgery, you may find yourself having some “emergency” bathroom visits. However, symptoms like diarrhea and vomiting should subside over time as you get a better handle on how your altered digestive system responds to food.

Myth: Bariatric surgery is reversible.

  • Gastric banding is usually reversible. That’s because the stomach and intestines are not cut or stapled with this surgery. Gastric bypass may be reversible, but this is a very involved surgery. It’s more difficult to put everything back where it was, and there is a risk that the revision won’t restore normal function. Sleeve gastrectomy and duodenal switch entail actual removal of part of the stomach without reattaching it lower on the intestine. This type of surgery is not reversible.

Surgery for weight reduction is not a miracle procedure. Weight loss surgery is designed to assist the morbidly obese in developing a healthier lifestyle. A surgical weight loss operation is a useful tool for weight loss, but it is a surgical procedure that requires a substantial lifelong commitment. The surgery alone will not help someone lose weight and keep it off. The patient must change eating and exercise habits. Without changes to the daily pattern of eating and activity, the patient is likely to regain the weight over time.

 

Gastric Bypass for a Longer Life

According to research by the Geisinger Health System, one of the largest health service organizations in the U.S., patients with severe obesity who have gastric bypass surgery reduce their risk of dying from obesity and other diseases by 48% up to 10 years after surgery, compared to similar patients who do not undergo the procedure. This is significant considering that the American Society for Metabolic and Bariatric Surgery estimates about 24 million Americans have severe obesity, which would mean a BMI of 35 or more with an obesity-related condition like diabetes or a BMI of 40.

Researchers from the Geisinger Health System followed nearly 2,700 patients who had gastric bypass at the system’s nationally accredited bariatric surgery center between 2004 and 2014. Mortality benefits began to emerge within two years after surgery and were significant within four years. The biggest reduction in risk occurred in patients 60 years or older at the time of surgery and in patients who had diabetes before surgery.

“The long-term survival benefits these older patients and those with diabetes experience likely relate to improvements in long-term metabolic and cardiovascular health, among other risk factors,” said Michelle R. Lent, Ph.D., a Geisinger Obesity Institute researcher. “While this study did not evaluate specific-cause mortality, as expected, we did find significant improvements or remission in diabetes and high blood pressure.”

In the study, more than 60 percent of patients with diabetes before surgery experienced diabetes remission about five years after surgery. Previous studies have shown death from heart disease and even certain cancers are lower in gastric bypass patients than patients with severe obesity who do not have the operation.

People with obesity and severe obesity have higher rates of heart disease, diabetes, some cancers, arthritis, sleep apnea, high blood pressure and dozens of other diseases and conditions. Studies have shown individuals with a BMI greater than 30 have a 50 to 100 percent greater risk of premature death compared to healthy weight individuals.Live Longer

Obesity: The Disease that Keeps on Growing

A number of studies have shown that individuals who are obese are often stereotyped as “lazy” or “lacking in willpower.” However, obesity is no longer considered a cosmetic issue that is caused by overeating and a lack of self-control. The World Health Organization (W.H.O.), along with National and International medical and scientific societies, now recognize obesity as a chronic progressive disease resulting from multiple environmental and genetic factors.

In the United States, epidemiological data from a study that measured the actual body size of thousands of Americans, showed that 34 percent of adults more than 20 years old are affected by obesity and 68 percent are overweight (2007-2008 data). Obesity affected 10 percent of children between two and five years of age, 2 percent of those between 6 to 11 years old, and 18 percent of adolescents.

Throughout the last 3 decades, the prevalence of obesity has been increasing at an alarming rate. Since 1985, the Center for Disease Control (CDC) has supported an ongoing study, conducted on a yearly basis by state health departments, to examine changes in obesity prevalence state-to-state, and has found the following:

  • In 1990, the obesity prevalence for most of the states was 10 percent or less.
  • By 1995, more than half the states had a prevalence of 15 percent.
  • By 2000, nearly half the states had a prevalence of 20 percent or higher.
  • Five years later (2005), all but three states had a prevalence greater than 20 percent and nearly a third had a prevalence of 25 percent or more.
  • By 2010, the data show that most of U.S. states had a prevalence of 25 percent and many had a prevalence of 30 percent or higher.

Obesity is considered a multifactorial disease with a strong genetic component. Acting upon a genetic background are a number of hormonal, metabolic, psychological, cultural and behavioral factors that promote fat accumulation and weight gain.

Many other conditions associated with obesity contribute to the progression of the AdobeStock_69574863 (2).jpgdisease. Obesity reduces mobility and the number of calories that would be burned in the performance of activity. Weight gain may also cause psychological or emotional distress which, in turn, produces hormonal changes that may cause further weight gain by stimulating appetite and by increasing fat uptake into fat storage depots.

Sleep duration is reduced by weight gain due to a number of conditions that impair sleep quality such as pain, sleep apnea and other breathing problems, a need to urinate more frequently, use of certain medications, and altered regulation of body temperature. Shortened sleep duration, in turn, produces certain hormones that both stimulate appetite and increase the uptake of fat into fat storage depots.

Weight gain also contributes to the development of other diseases such as hypertension, diabetes, heart disease, osteoarthritis and depression, and these conditions are often treated with medications that contribute to even further weight gain. In all of these ways and more, obesity ’begets’ obesity, trapping the individual in a vicious weight gain cycle.

Multiple factors acting upon a genetic background cause weight gain and obesity. Conditions associated with weight gain and biological changes in the body that occur as a result of weight gain contribute to progression of the disease, often trapping the individual in a vicious weight gain cycle. Obesity is a complex disease influenced by several issues, including genetic, physiological, environmental, and behavioral.

Get the Facts about Bariatric Surgery

Bariatric surgery is an option that many obesity medicine specialists say is too often ignored or dismissed. Yet it is the only option that almost always works to help very heavy people lose a lot of weight. Weight-loss surgery can also make some chronic conditions vanish entirely.

Here are some facts about bariatric surgery and what it does:

  • Twenty-four million, Americans are eligible for bariatric surgery according to the American Society for Metabolic and Bariatric Surgery. The criteria are a body mass index (BMI) above 40, or a BMI of at least 35 along with other medical conditions like diabetes, hypertension, sleep apnea, or acid reflux.
  • Fewer than 200,000 have the surgery each year.
  • There are four surgical types in use today. The two most popular procedures are the Roux-en-Y gastric bypass and the gastric sleeve. Both make the stomach smaller. The bypass also reroutes the small intestine. A simpler procedure, the gastric band, is less effective and has fallen out of favor. And a much more drastic operation, the biliopancreatic diversion with duodenal switch, which bypasses a large part of the small intestine, is rarely used because it has higher mortality and complication rates.
  • The average cost of a sleeve gastrectomy is $16,000 to $19,000, and the average cost of a gastric bypass is $20,000 to $25,000. Most insurance plans cover the cost for patients who qualify, though some plans require that patients try dieting for a certain amount of time first.
  • Bariatric surgery is not a magic bullet that will solve all of your weight-related problems. Leading a healthy lifestyle full of healthy foods and exercise post surgery is crucial.

Fighting Type 2 Diabetes with Weight-loss Surgery

In a recent study, researchers were able to identify genetic markers that could predict the risk of type 2 diabetes (T2DM). Doctors hope that this will lead to new strategies for predicting and possibly preventing T2DM and other consequences of being overweight. These findings are particularly important, as an estimated 1.5 billion people throughout the world are overweight. Researchers hope their findings could lead to better ways at identifying those most at risk of developing diabetes and help them make changes in their lifestyles to ensure they do not go on to develop this condition.

Here are some things we know:

  • Obesity is a major independent risk factor for developing type 2 diabetes, and more than 90% of type 2 diabetics are overweight or obese.
  • Modest weight loss, as little as 5% of total body weight, can help to improve type 2 diabetes in patients who are overweight or obese.
  • Metabolic and bariatric surgery may result in resolution or improvement of type 2 diabetes independent of weight loss.

Current therapy for T2DM includes lifestyle intervention (weight-loss, appropriate diet, exercise) and anti-diabetes medication(s). Medical supervision and strict adherence to the prescribed diabetes treatment regimen may help to keep blood sugar levels from being excessively high although medications and lifestyle changes cause remission of the disease. In fact, T2DM often worsens with time, requiring even greater numbers of medication or a higher dosage to keep blood sugar under control. For this reason, T2DM has been considered a chronic and progressive disease.

Weight loss surgery may improve blood sugar control by altering levels of gut hormones, as well as by speeding up weight loss. It may also alter the balance of microbes in the digestive system in beneficial ways.

  • Studies comparing metabolic and bariatric surgery to nonsurgical treatment for obesity found surgery results in greater weight loss and higher type 2 diabetes remission rates.
  • Studies with more than six months follow up showed surgical patients lost an average of 57 more pounds than participants in nonsurgical weight loss programs, and were 22 times more likely to see their type 2 diabetes abate.
  • Head-to-head studies comparing bariatric surgery to medical therapy found bariatric surgery superior to medical treatment in producing type 2 diabetes remission, even before weight loss.
  • A Cleveland Clinic study showed within one year, diabetes remission rates with bariatric surgery were about 40% (42% gastric bypass, 37% gastric sleeve) compared to about 12% for patients treated with the best pharmacotherapy available; patients had BMI between 27 and 43.
  • Catholic University/New York-Presbyterian/Weill Cornell Medical Center showed remission rates were about 85% for bariatric surgery (75% gastric bypass, 95% Overweight Woman is Overjoyedbiliopancreatic diversion) and zero for medical therapy in patients with BMI greater than 35, after two years.
  • In surgical groups, both weight loss and preoperative BMI were not predictors of diabetes control, suggesting such surgical procedures may be independent of weight loss.
  • 73% of gastric band patients with type 2 diabetes experience remission two years after surgery, a 5 times higher resolution rate than those receiving convention therapy.
  • Conventional therapy includes access to general physician, nurse and diabetes educator, and medical therapies including pharmaceutical agents, individual lifestyle modification programs, and physical activity.

The American Diabetes Association recommends bariatric surgery be considered for adults with type 2 diabetes who have a BMI greater than 35, in particular if diabetes or associated comorbidities are difficult to control with lifestyle and pharmacologic therapy.
