Researchers in Hong Kong recently conducted a study of patients who received bariatric surgery, a procedure to lose weight. 5 years after the surgery, they compared patients who had undergone bariatric surgery to a control group of obese patients who had never undergone bariatric surgery. The study found that glucose and cholesterol levels, as well as blood pressure were significantly better in the group of people who had undergone bariatric surgery.
