Three years after undergoing bariatric surgery, adolescents experienced major improvements in their weight, metabolic health, and quality of life, according to findings from the prospective, NIH sponsored Teen-LABS (Longitudinal Assessment of Bariatric Surgery) study.
The multicenter clinical study enrolled 242 adolescents (ages 13 to 19; 75% female) all of whom were severely obese (average weight presurgery, 325 pounds).
Three years after surgery, mean weight reduction in the overall group was 41 kg, and the mean percent weight loss was 27% (28% with gastric bypass and 26% with sleeve gastrectomy). Reversal of type 2 diabetes was seen in 19 of the 20 patients (95%) who had follow-up data that could be evaluated. In addition, 13% of patients required additional abdominal surgery, most commonly gallbladder removal (8%), during the 3-year follow-up period. This glycated hemoglobin test is carried out on people to find out how an individual reacted to diabetes controlling measures in last six to twelve weeks. FDA Advisory Panel votes 8-2 in favor of an insulin dosing label update for Dexcom's G5 CGM! Kelly: Some researchers call gastric bypass surgery the most reliable cure for type 2 diabetes. Jessica: On that note, which diabetes patients have the most success with metabolic surgery? I think that this perspective has enormous significance on populations of people who get diabetes at lower BMI levels, such as Asians and Asian Indians. Jessica: In order for us to have a better understanding of metabolic surgery, can you discuss the risks of having the surgery? But for pulmonary emboli, there are baseline characteristics that put a patient at greater risk for getting a blood clot. Although I’m not an expert for young patients, I know that many of us are concerned that the operation could cause the malabsorption of micronutrients like vitamins. Jessica: Could you describe the different kinds of bariatric surgery and which would be best for a particular patient?

Our mission is to help individuals better understand their diabetes and to make our readers happier and healthier. People who have diabetes and are severely overweight are deciding more and more often that bariatric surgery is just the thing for them. Some people, including a couple of my friends, have had wonderful results from bariatric surgery. A study presented yesterday at the annual meeting of the American Society for Metabolic and Bariatric Surgery can help you decide. Roux-en-Y is the name of the most commonly performed bariatric surgery in the United States. People who weren’t using insulin and whose pancreatic beta cells were working better were much more likely to get remission of their diabetes.
They measured how well the beta cells were working by using something they call the “glucose disposition index.” If the patients had a GDI of 30 percent of normal or less, they were less likely to achieve remission. What didn’t make a difference in remission rates was how much the patient weighed before surgery and whether they had lost any weight after six weeks or after one year. What the study does make clear is that if you are going to have bariatric surgery, it’s better not to wait until your diabetes has become completely unmanageable. While Roux-en-Y gastric bypass is the most common bariatric surgery, different hospitals use different techniques, including less invasive laparoscopic surgery. Generally, about 2.5 percent of people who have bariatric surgery have serious complications, according to a study last year in Annals of Surgery. A recent and comprehensive review in The New England Journal of Medicine shows somewhat worse statistics.
Whenever people have asked me about bariatric surgery for weight loss, I have always suggested that they consider it only as a last resort. While lifestyle changes like following a very low-carb diet can put diabetes into remission for some of us, others can’t afford to wait to lose weight without surgery. Last observation, I know a couple of ladies that have had this procedure and I don’t see where their quality of life has been improved.
Tania Markovic received money from the Australian Egg Corp to do a study looking at the impact of eggs on people with type 2 diabetes.
Overweight and obese people have an increased risk of high blood pressure, type 2 diabetes and cardiovascular disease, as well as arthritis, obstructive sleep apnoea and liver disease.
But it is highly invasive, it comes with a number of risks and in some cases is not effective. There are three main types of bariatric surgery available in Australia: laparoscopic adjustable gastric band (LAGB), sleeve gastrectomy and gastric bypass.
LAGB is a relatively simple operation in which an adjustable silicone balloon ring is placed around the upper stomach.
But it is easier to consume fluids than denser, healthier foods, reducing the quality of the diet, which might explain why LAGB results in less weight loss than other procedures. For sustained weight loss, close follow up is needed, with optimal adjustment of the band; if the band is too tight, it’s difficult to eat healthy foods and obstruction may occur, if the band is too loose, appetite is not controlled.
Revision surgery is required in about 15% of patients within three years due to band slippage and erosion of the band into the stomach wall.
The weight loss and improvement in diabetes is related to both reduced capacity of the stomach and an increase in hormones that reduce appetite and increase meal related insulin release. Nutritional deficiencies are common and most people need supplements of nutrients normally absorbed by the stomach.
This operation creates a small proximal stomach joined to the end of the jejunum (the lower small bowel) so that parts of the small bowel, where nutrients are absorbed, are bypassed. Gastric bypass results in more weight loss than the sleeve gastrectomy as there is both a reduction in the capacity of the stomach and reduced absorption of nutrients, including the beneficial changes in gut hormones seen with the sleeve gastrectomy.
In some patients, the weight loss is so great that they become malnourished and all patients require life-long supplements of vitamins, calcium and other minerals. In addition to the complications of surgery and malnutition, the long-term effects can include reduced bone density and impairment in nerve function.
There is also a reported increased incidence of suicide and substance abuse in patients who have had bariatric surgery. It’s important to note that individuals do not need to attain the amount of weight loss achieved with surgery to have substantial beneficial health outcomes. These guidelines are based on those developed by the United States' National Institute of Health (NIH) in 1991, when a different range of operations were available and surgery was not performed laparoscopically.


Losing just 5% to 10% of your body weight can improve your health, especially if it’s coupled with exercise.
The reduction of the threshold may result in too many people having surgery inappropriately. Despite the proven efficacy of bariatric surgery, there is no way that it can be delivered on a mass scale. Furthermore, there are many new treatments in the pipeline that may mimic the beneficial effects of surgery, such as medications with effects on multiple hormone pathways and less invasive surgical procedures that may be as effective as the current operations with fewer complications. The thing all five viruses have in common is they can cause mild to very severe liver damage. The network of interactions between obesity, cardiac and renal impairment comprises a complex multisystemic dialogue including neurohormonal, endocrine, paracrine and inflammatory signalling. Vitamin B12 levels decreased by 35% in the overall group, with 8% of patients having deficient levels at 3 years. In some less frequent cases, children or even infants are diagnosed with this metabolic disorder. Those who find encouraging results of limiting their HbA1c values, thereby indicating controlled diabetes, can extend their time intervals of testing. David Cummings, a highly respected researcher from the University of Washington, Seattle, talked to us about the evolving field of metabolic surgery for type 2 diabetes. What is the rationale behind the shift towards using the term “metabolic surgery” instead of “bariatric surgery”? Cummings: I think there has been a shift in mindset about the reasons for seeking out surgery. Cummings: If you have type 2 diabetes and have gastric bypass, you enjoy complete remission in about 80% of cases. But for people with prediabetes, what are the odds for delaying or preventing diabetes onset?
National guidelines tell healthcare providers to use BMI to select candidates, but we have heard that BMI is not the best predictor of success.
This is a very small number of the population, but anyone who has a history of hypercoagulability would be of special concern. While children and adolescents are getting taller, epiphyseal plates, the cartilage at the ends of their bones, are open and allow for growth. The new connection bypasses the remaining stomach pouch below, though both pouches are still connected to the small intestine. Although it is expensive and like any surgery it can have complications, the amount of weight that they lose is usually dramatic and their diabetes often completely disappears.
Perugini and his colleagues studied what happened to 139 consecutive people with type 2 diabetes who had the Roux-en-Y operation. The study found that overall 67 percent of these gastric bypass patients achieved remission one year after surgery, but that number grew to 96 percent when they weren’t on insulin and didn’t have severely reduced pancreatic function. Perugini’s remark about diabetes progression relates to the old strategy of countering the typical high-carbohydrate diet with more and more diabetes drugs culminating in insulin.
Even then,  you need to consider the many different types of bariatric surgery, where to have the surgery, the possible complications, and how much it costs. Other common procedures include gastric banding, one of the least invasive surgeries, and the relatively new sleeve gastrectomy. Hospitals and individual surgeons who have more experience with bariatric surgery do better, according to an Agency for Healthcare Research and Quality study.

The World Health Organization estimates 35% of the world’s adults are overweight and 11% obese, double the rate in 1980. Obesity can reduce life expectancy by five to 20 years, and the obesity epidemic may soon reverse the gains that have been made in human longevity. But, of course, it’s not that simple; many of us find it impossible to consistently control our calorie intake. It is recognised as the most effective treatment for obesity, resulting in both the largest and most sustained weight loss, and the greatest reduction in obesity-related disease and death. As well as restricting the volume of food the stomach can hold, the pressure created by food in the reduced upper stomach stimulates the vagal nerve, reducing appetite. It is technically simple and is reported to have a good safety profile in experienced hands.
There is also the risk of “dumping syndrome” due to the rapid transit of undigested food from the new, smaller stomach to the bowel, causing nausea, cramps, diarrhoea, and occasionally low blood sugar from very high insulin levels. But there have been few controlled studies comparing the quality of life after surgery with patients who have not sought surgery. A reduction in weight of 5% to 10% can improve the health of your heart and reduce obesity-related disease and early death, especially if combined with increased physical activity. Because of this, some researchers have recommended governments lower the threshold of eligibility to include people with a BMI over 30 without metabolic complications. While bariatric surgery is the most robust treatment for obesity, it is invasive, often irreversible and has associated risks.
This surgery should be reserved for patients with severe obesity or patients with diabetes who have been compliant with treatment but have been resistant to medical treatments. Metabolic surgery can reverse systemic hypertension, improve systolic and diastolic function and precipitate reverse cardiac remodelling leading to improvement of obesity-associated cardiomyopathy. In addition, abnormal kidney function resolved in 86% of the overall group, hypertension normalized in 74%, and lipid abnormalities reversed in 66%. Vitamin A deficiencies in the gastric bypass group increased from 6% at baseline to 16% at 3 years (P=0.008).
This is one ailment where a person is found to have higher amounts of sugar in the blood stream.
The main function of hemoglobin is to transport oxygen to all parts of the human body through the blood circulation cycle.
However the tests must be carried out at least once in six months, even in such situations. Remission means that, for at least a period of time, you’ll come off all your diabetes medications, including insulin, if you used to be on it, and have non-diabetic glucose levels (an A1c below 6.5%).
According to the SOS Trial, which is probably the best dataset in the field, the factors that actually predicted the benefits of surgery were high fasting glucose levels and high fasting insulin levels.


Leaks can occur when the new junctions of the gastrointestinal tract are not connected well during surgery. People who have had pulmonary emboli or deep venous thrombosis, or any family history of hypercoagulability, such as Factor V Leiden, should have second thoughts about whether the surgery is for them. Then at some point, the cartilage becomes bone, the plates close off, and they cannot grow any further.
Keep in mind, that the safety of gastric bypass is somewhere in the same range as having your gallbladder removed. The probability of patients dying of their disease – diabetes, hypertension, cholesterol, or any other obesity-related complication – has repeatedly been shown to be higher than the probability of dying from surgery. We greatly appreciate and admire the work that he does for patients and we look forward to continuing to learn from his research on metabolic surgery.
The researchers particularly wanted to find out who experienced remission of their diabetes.
It’s getting a little less expensive, but the mean cost to all payers in 2004 was $10,385, the Agency for Healthcare Research and Quality says. The proportion of people whose diabetes goes into remission after this surgery is impressive, particularly when people with diabetes don’t wait until they have only a few working beta cells. But bariatric surgery is for people who can’t lose weight, not that they have to lose weight first. For those with severe obesity or diabetes who have tried all other medical options but failed to lose weight, bariatric surgery is the last-line option.
By modulating the entero-cardiac axis, metabolic surgery might also improve cardiac function via the actions of hormones such as GLP-1 and ghrelin and the adipokines leptin and adiponectin. Vitamin D deficiency was found in 37% of patients at baseline with no significant change found over time.
Higher blood sugar results in increased frequency of urination and increased bouts of thirst or hunger.
When the sugar in the diabetes affected person is not controlled and is present in higher proportions, the excess sugar tends to get attached to hemoglobin. Studies have indicated that figures beyond 7.0 % indicate that the diabetic situation can lead to further complications.
People who care about their health should follow the proper regimen of HbA1c testing to rid of complications.
Lena Carlsson’s 2012 New England Journal of Medicine paper on the Swedish Obese Subjects (SOS) trial: surgery reduced the probability of developing diabetes by 80% over 15 years. What is clear to me is that people who are more insulin-resistant benefit the most from surgery on many outcomes including the prevention of diabetes, heart attacks, strokes, and overall risk of dying. I don’t know of a good way to predict whether that will happen in one patient versus another so it’s a low probability concern that applies to everyone. Most of us in the field think a conservative practice would be to wait until the epiphyseal plates have closed and linear growth has ended because the surgery might put patients at risk of a vitamin D deficiency.
We just don’t have anywhere near the richness of data for its long-term efficacy and safety as we do with bypass. The abstract of the study, “Predictors for Remission of Type 2 Diabetes Mellitus Following Roux En Y Gastric Bypass,” is online. Using insulin therapy as a surrogate for the degree of diabetes control makes sense some of the time — but not always.
Sustained weight loss after surgery may reduce glomerular hyperfiltration, reduce albuminuria and improve renal function.
Status of anemia, the existence of a kidney or liver malfunction or presence or vitamin C or E supplements, higher cholesterol levels can adversely affect the results of this test.
He has spent the past 20 years specializing in gastrointestinal surgery, studying its effects on diabetes remission (please see the Metabolic Surgery Primer at the end of the article for specific definitions), and the mechanisms for how body weight, glucose, and appetite are controlled. But it’s very well established that about 80% of patients will undergo remission as defined above.
The press got a hold of the paper, and they spun it as saying lots of people with diabetes who have remission get diabetes again, implying that if your diabetes is only going to be temporarily remitted, you shouldn’t have surgery.
Excessive weight loss, gross malabsorption, under nutrition, and protein calorie malabsorption are not gastric bypass complications. If we were talking about biliopancreatic diversion, that’s a bigger deal, and it carries a significant risk, perhaps more than 1%, of death in operation.
In comparison, the chance of dying within 30 days after gallbladder removal is 0.3% in the US. Furthermore, resolution of type 2 diabetes mellitus and systemic hypertension might reduce progression or even reverse chronic kidney disease.
One of the group called as Type 1, refers to patients having absence of insulin producing mechanism in the body. In case of such situations, thorough body check up is recommended, before arriving at definite conclusions.
It also poses a significant risk of complications such as malnourishment, and excessive weight loss. Another group known as Type 2, refers to people, who have insufficient production of insulin or whose cells do not react to insulin.
Bush presented him with the US Presidential Early Career Award for Scientists and Engineers – the highest award given to young researchers by the US government. Patients who have surgery will need to take post-operative iron and vitamin B12 supplements.
The fear of bariatric surgery comes from attention bias – it’s the bad cases that get press and stick in your memory. We’ve been lucky to follow his work at multiple scientific meetings over the last several years. It does seem to work pretty well, but we don’t know why it works and we’re waiting for a longer-term data.
A third category called Gestational Diabetes is found in pregnant women, caused by complex reactions in their body. Persons diagnosed with diabetes are required to undergo some regular and some occasional tests to determine the severity of their disorder and for deciding corrective medication or treatment. HbA1c utilizes averages over longer periods and hence the results carry greater importance in medical terminology.
