Fat Loss Ketogenic Diet - Weight-Loss Surgery Seems to Beat Diet and Exercise
Tuesday, October 22 (health news) - For people who are very weight to lose, weight loss surgery seems more effective than diet and exercise, a new revision suggests.
The caveat of this study, however, is that the results include only two years of data, so that long-term results are still unknown. This type of study, called meta-analysis, tries to discover a common wire in several previous studies.
"individuals allocated for bariatric surgery have lost more body weight - on average 26 kilos [57.3 pounds] - compared to non-surgical treatment, and presented higher rates of remission of type 2 diabetes and metabolic syndrome", The author of the study Viktoria Gloy, a scientist at the Institute of Basel of Clinical and Bio-Stage Epidemiology at the University Hospital Basel in Switzerland. Metabolic syndrome is a group of symptoms that increase the risk of type 2 diabetes and heart disease.
"After surgery, patients also reported further improvements in quality of life measures, and had greater reduction in the use of medication than non-surgical patients," added Gloy.
Gloy and colleagues published the October 22 October 22 discoveries at BMJ.
obesity is a significant risk to public health, according to basic information in the report. The incidence of obesity more than doubled in the last 25 years in the United States in the United Kingdom and Australia. More than two-thirds of the U.S population. It is currently overweight or obese. Many European countries are not far behind, with overweight and obesity rates of about 40% to 50%, according to researchers.
Obesity increases the risk of many serious diseases, including type 2 diabetes, high blood pressure, high cholesterol, cardiovascular disease, some types of cancer and musculoskeletal diseases such as osteoarthritis, according to the analysis.
Treatments for obesity include weight loss surgery and non-surgical options such as dietary changes, medications and increased physical activity.
To see what the treatments help people lose weight and improve their health, Gloy and his colleagues analyzed previously completed studies on weight loss, and found 11 studies with almost 800 people who have suffered a surgery Weight loss or non-surgical weight loss treatments.
In addition to losing more weight, those who had weight loss surgery had a rate of remission of type 2 diabetes that was 22 times higher than in the group that did not receive surgery. Metabolic syndrome rates also fell more to those who have had surgery, according to the analysis.
. Triglycerides, a type of blood fat, fell more, and the levels of good cholesterol (HDL) increased more for those who had surgery.
There were no significant differences in blood pressure levels and bad cholesterol levels (LDL) between the two groups, researchers found.
"Evidence beyond two years of accompaniment, at adverse events, cardiovascular diseases and mortality, remains clear and requires more research on the theme," Gloy noted.dr. Joel Zonszein, director of the clinical center of Diabetes at Montefiore Medical Center in New York said: "Weight gain is very easy, but lose weight is very difficult. This was a careful meta-analysis, and I agree with what they "We consider. We still do not understand exactly how bariatric surgeries cause remission of type 2 diabetes, "he pointed out.
Another expert said weight loss surgery should be happening more often.
"Bariatric surgery is underutilized. If we were talking about any other treatment with such a striking effect on diabetes, it would be offered to patients sooner," said Dr. Mitchell Roslin, head of Obesity Surgery at Lenox Hill Hospital in Novo York City.
Claro, as any surgery, weight loss surgeries do not come without risk. The most common complications reported in the current analysis were iron deficiency anemia and the need to re-operate. Surgery is also expensive. The National Institute of Diabetes and Digestive and Renal Diseases estimates that weight loss surgery is an average of $ 25,000.
Roslin and Zonszein say people submitted to weight loss surgery need to be carefully chosen. Current recommendations recommend surgery for anyone with a body mass index (BMI) above 40, or an IMC of 35 or higher if they have other conditions related to obesity, such as type 2 diabetes or high blood pressure. BMI is a measure based on height and weight.
But both experts felt that more people should be included in these recommendations. Zonszein said people with BMIs as low as 30 if they had evidence of other metabolic abnormalities, should be advised in surgery. Roslin also said that if people with type 2 diabetes can not keep control over oral medications that a surgical option should be offered.
Roslin said people with type 2 diabetes should try to lose weight and exercise more first. "Give yourself a chance to make changes in the lifestyle. But it is very difficult to lose 5% of your body weight. If you do not think you will be able to do this, then you owe yourself to learn about surgical options, " he suggested.
"There are real risks with surgery that should not be underestimated, but there are actual risks of diabetes," Roslin noted. "Let's say we were talking about colon cancer instead of diabetes, and I said," There is a treatment that could reduce your risk at 22 times, but it's invasive, would you consider it? "
