Women who adhered to lifestyle habits related to weight control, diet, smoking, daily exercise and caffeine intake had a lower risk for gastroesophageal reflux disease symptoms, compared with those who did not follow the plan, according to a study led by Raaj S. Mehta, MD, from Massachusetts General Hospital and Harvard Medical School, and published in JAMA Internal Medicine. The lifestyle changes may prevent up to 40% of the weekly GERD symptoms, researchers wrote.
