Gastric bypass surgery lowers women’s alcohol tolerance​

Women who have gastric bypass surgery to lose weight should keep a close eye on their alcohol consumption, according to a study at Washington University School of Medicine in St. Louis. The researchers found that changes in how alcohol is metabolized after surgery can speed its delivery into the bloodstream, resulting in earlier and higher peaks in blood-alcohol levels.

Weight loss, not surgery, controls blood sugar

Gastric bypass surgery has been thought to offer advantages, independent of weight loss, for improving insulin sensitivity and blood glucose levels in obese patients. But new research at Washington University School of Medicine in St. Louis shows that those improvements are related to weight loss alone and not to the surgical procedure itself.
