Leicester study seeks to understand ongoing impacts of exercise after weight loss surgery

Weight-loss (bariatric) surgery is an effective method which helps people living with severe obesity to achieve and maintain substantial weight loss and live longer. Exercise after bariatric surgery is an important factor which improves fitness, physical function (e.g. strength, endurance and flexibility), and health related quality of life.

Recent research suggests that aerobic exercise after bariatric surgery (in people without type 2 diabetes) increases the bodies’ effectiveness to use the sugar in the blood (insulin sensitivity). Increased insulin sensitivity can cause episodes of low blood glucose levels in individuals’ post-bariatric surgery especially after eating and when undertaking daily lifestyle activities. This can contribute to a reduction in quality of life and cause weight regain.

Current guidelines recommend that after bariatric surgery, individuals should undertake 30 minutes of aerobic exercise. However, there is lack of evidence on the effect of aerobic exercise on blood glucose levels.
