Long-term benefits of weight loss surgery revealed by new study

4 January 2016

The widespread long-term benefits of weight loss surgery have been demonstrated by a new study from the London School of Hygiene & Tropical Medicine.

Published in the journal PLOS Medicine, the research indicated that bariatric surgery delivered in routine clinical practice in the UK is associated with a substantial initial weight loss sustained for at least four years after surgery.

Weight-loss operations were also shown to be associated with improvements in pre-existing type 2 diabetes and hypertension, as well as a reduced risk of the onset of several obesity-related comorbidities.

These findings were based on a study of 3,882 bariatric surgery patients and comparable control subjects who did not have surgery, tracked using primary care records in the UK Clinical Practice Research Datalink.

Assuming these links are causal, the researchers estimated that wider use of bariatric surgery in the UK over a four-year period could prevent or resolve around 93,000 cases of hypertension and 149,000 cases of type 2 diabetes.
