These problems can result from bacteria in food, infections, stress, certain medications, or chronic medical conditions such as colitis, Crohn's disease, and irritable bowel syndrome. But whatever the cause, anyone with frequent digestive problems faces daily challenges and potential embarrassing situations. Functional diseases are those in which the gastrointestinal tract looks normal when examined, but does not move properly. These are the most common problems affecting the gastrointestinal tract (including the colon and rectum).
Constipation, irritable bowel syndrome (IBS), nausea, food poisoning, gas, bloating, GERD, and diarrhea are common examples. People can experience stomach problems for a number of reasons. These can be as common as poor eating habits. However, in some cases, stomach problems can be caused by common digestive disorders.
Digestive disorders encompass a variety of illnesses that range from mild to severe. Common digestive disorders include gastroesophageal reflux disease, cancer, irritable bowel syndrome, lactose intolerance, and hiatal hernia. Digestive diseases are disorders of the digestive tract, which is sometimes referred to as the gastrointestinal (GI) tract. Digestive disorders are a group of conditions that occur when the digestive system doesn't work as it should.
