Bariatric weight loss surgery on obese patients with type 2 diabetes helped many to get their blood sugar to healthy levels and to no longer require any diabetes medicines, including insulin, three years after the procedure, according to data presented at a major medical meeting on Monday. The surgery also helped patients reduce the need for high blood pressure and cholesterol medicines and led to quality of life improvements compared with those who received medical weight-loss therapy, researchers found. The study called Stampede, which involved 150 obese patients who had poorly controlled type 2 diabetes for at least eight years, was conducted by Cleveland Clinic researchers. It compared two types of weight loss surgery against weight loss attained by diet and exercise along with nutrition counseling and, for some, additional diabetes medicines that can help promote weight loss, such as Victoza from Novo Nordisk.
