Patient behaviours associated with post-surgery weight regain

In the years following bariatric surgery, a person's overall eating behaviours and the amount of time spent watching television, playing video games and using a computer for recreation are a better indication of long-term weight loss success than specific weight control practices like counting calories, according to findings by the University of Pittsburgh Graduate School of Public Health.

Race plays role in weight regain after Roux-en-Y gastric bypass

African Americans and Hispanic Americans who have undergone Roux-en-Y gastric bypass (RYGB) are at greater risk to regain weight compared to Caucasians, according to researchers from Boston Medical Center (BMC), who stated that a greater degree of vigilance is warranted for African American and Hispanic American patients who are at higher risk for weight regain.

Amount of weight regain after surgery can predict health risks

Measuring the percentage of weight regained following the maximum amount of weight lost after bariatric surgery can help predict a patient's risk of several serious health problems, according to a long-term, multi-centre study led by University of Pittsburgh Graduate School of Public Health researchers. The results also found that while on average study participants achieved maximum weight loss at two years post-surgery, when they reached that milestone the outcomes varied substantially with approximately 20 percent continuing to lose weight more than four years post-surgery.

Post-bariatric surgery weight regain may be population-specific

Approximately 20% of bariatric surgery patients will regain weight after two years and, according to researchers from Mexico, the factors influencing regain are still controversial but may be population-specific. They stress that early detection of the patients that are more likely to fail is imperative to establish additional therapeutic strategies, without denying them the opportunity of surgery or waiting for weight re-gain to occur.

Greater weight loss at five years for Banded-LSG vs. non-banded-LSG

Five year outcomes from a single-centre study comparing banded laparoscopic sleeve gastrectomy (BLSG) with non-banded laparoscopic sleeve gastrectomy (NLSG) has found that BLSG was more effective in reducing and maintaining weight – with more than 97% of the patients in the BLSG group reporting no weight regain at all, compared to the NLSG group, where only 80% of the patients had no weight regain.

Obesogens may interfere with body weight regulation

A class of chemicals used in many industrial and consumer products has been linked to greater weight gain after dieting, particularly among women, according to a study led by Harvard TH Chan School of Public Health. The chemicals - perfluoroalkyl substances (PFASs) – have previously been linked with cancer, hormone disruption, immune dysfunction, high cholesterol, as well as obesity.

Weight regain: Post-op adjuvant weight loss medication is effective

Adjuvant weight loss medications after bariatric surgery can stop weight regain and maintain weight loss, according to a study by researchers from the Bariatric and Metabolic Institute, Department of General Surgery, Cleveland Clinic, Cleveland, OH. The study found that more than one third of patients who received adjuvant weight loss medications achieved>5% weight loss and the response was ‘significantly better’ in gastric bypass and gastric banding patients, compared with sleeve gastrectomy patients.

Dieting and HIIT exercise reduces risk of weight regain in mice

Researchers at the University of Alabama at Birmingham have found that combining a calorie-restricted diet with high-intensity interval training could be a solution for reducing weight regain after weight loss. The team found that, in the presence of a calorie-restricted diet, high-intensity exercise training preserved muscle mass and had a greater impact on the way the body uses glucose for energy, in mice.

LGGCP improves comorbidities but majority regain weight

Laparoscopic gastric greater curvature plication (LGGCP) has ‘acceptable’ short-term weight loss and improved patients’ comorbidities however, some patients regained weight, according to researchers from Qatar and published in the Journal of Obesity.

Artificial sweeteners linked to risk of weight gain

Artificial sweeteners may be associated with long-term weight gain and increased risk of obesity, diabetes, high blood pressure and heart disease, according to researchers from the University of Manitoba's George & Fay Yee Centre for Healthcare Innovation and the Children's Hospital Research Institute of Manitoba, Winnipeg, Manitoba.
