As reported on RefluxMD, being overweight or obese increases one's risk of countless diseases and conditions, including frequent heartburn, also referred to as GERD (gastroesophageal reflux disease). GERD is a digestive disorder affecting up to 60 million Americans, and is closely associated with obesity, with evidence suggesting that being overweight greatly increases this risk. A very effective heartburn relief is improved diet, consisting of less greasy and fatty foods, and safe and effective weight loss.
