Digestive disorders are very common and affect millions of Americans every year. Digestive disorders are conditions that affect the digestive tract, which is made up of the esophagus, stomach, liver, gallbladder, pancreas, and intestines. Most people experience digestive problems at some point in their lives. In fact, antacids and laxatives are some of the most common over the counter medications sold in the United States. Digestive symptoms vary greatly in severity. While a digestive upset is a common occurrence, having symptoms regularly could be an indication of a digestive disorder. Some of the most common digestive disorders include: irritable bowel syndrome (IBS), gastro-esophageal reflux disease (GERD), celiac disease, and inflammatory bowel disease (Chron’s and ulcerative colitis).
