The holidays are approaching and all those great treats can sometimes cause discomfort.GERD (Gastroesophageal Reflux Disease), affects millions of people every year.Reflux means that stomach acid and juices flow from the stomach back up into the tube that leads from the throat to the stomach (esophagus). This causes heartburn. When you have heartburn that bothers you often, it is called gastroesophageal reflux disease, or GERD.Having heartburn from time to time doesn't mean that you have GERD. With GERD, the reflux and heartburn last longer and come more often.Though GERD can be uncomfortable, it is treatable.Mick Meiselman, MD, is here to discuss the symptoms and treatment options available at NorthShore University HealthSystem.
