Bariatric surgery may prevent strokes and extend life expectancy

Patients with obesity who undergo bariatric surgery live longer and are less likely to experience a clot-caused stroke than those who do not, according to preliminary research to be presented at the American Heart Association's Scientific Sessions 2019, in Philadelphia.

Surgery activates vagal stretch sensors reducing appetite

Researchers from UC San Francisco have suspected for some time that one reason bariatric surgery is so surprisingly effective at blocking hunger is that it causes food to pass very rapidly from the stomach into the intestine, but the mechanism has been unknown. New findings suggest an answer: that rapidly incoming food stretches the intestine, thereby activating the vagal stretch sensors and powerfully blocking feeding.

Age not a barrier to the benefits of bariatric surgery

A study has revealed that bariatric surgery can lead to successful weight loss and better diabetes control in older adults (above the age of 65). The study, presented at the Society for Endocrinology annual conference in Brighton, UK, indicates that elderly patients treated with either gastric bypass or gastric sleeve can recover well and have a reduced risk of obesity-related complications, including heart disease and diabetes.

Surgery decreases diabetic kidney disease in adolescents

Researchers at Children's Hospital Colorado (Children's Colorado) have found that severely obese teens with type 2 diabetes experienced a dramatic decrease in the rate of diabetic kidney disease, among other benefits, after bariatric surgery when compared to those who received medical treatment alone.

Cleveland Clinic calculator estimates ten-year risk of T2DM complications

A new risk calculator developed by Cleveland Clinic researchers can show patients who are struggling with type 2 diabetes and obesity their risks of developing major health complications over the next ten years depending on which course of treatment they choose. The research was presented as one of the Top 10 studies at the ObesityWeek 2019 international conference in Las Vegas.

Gastric bypass reduces risk of birth defects

Children born to women who underwent gastric bypass surgery before becoming pregnant had a lower risk of major birth defects than children born to women with severe obesity at the start of their pregnancy, according to a matched cohort study by researchers at Karolinska Institutet and Örebro University, Sweden.

Treating adolescent obesity - the evidence behind the options

As rates of adolescent obesity continue to rise, choice of treatment needs to be guided by the severity of obesity, psychosocial factors, comorbidities and patient's age and pubertal status, according to a paper published in the Journal of the American Medical Association.

Increase in psychiatric illness presentations after bariatric surgery

Researchers from Australia have reported an increase in mental health service presentations after bariatric surgery, particularly among those who had prior psychiatric illnesses or developed surgical complications requiring further surgery.

Large-scale ERP improves outcomes for bariatric surgery patients

A large-scale implementation of a protocol to improve recovery of patients after weight-loss operations was found to reduce rates of extended hospitalisation by almost half at 36 participating accredited bariatric surgery centres in the US. The study compared outcomes of 8,946 bariatric operations before with 9,102 operations that occurred after implementation of the protocol, known as an enhanced recovery program (ERP).

Women more likely to use post-op contraception after counselling

A study from the Netherlands examining contraceptive use pre- and post-operatively in women who underwent bariatric surgery has reported that 60% of women are using safe contraception post-operatively. However, only 62.6% of patients recall receiving contraceptive counselling but, the investigators noted, they were more likely to use safe contraception after surgery. Therefore, the authors recommended more counselling and monitoring in the post-operative and outpatient setting.
