Digestive disorders persist to be among the most common problems in health care. The consumption of high cholesterol and dietary fat intake, highly spicy foods, alcohol, nicotine, caffeine provoke gastric acid secretions. The consumption of vegetable and fruit and dietary fibre intakes are known to protect the gastrointestinal tract against various diseases. Gastroesophageal reflux disease, hiatal hernia, gastritis, peptic ulcers and dumping syndrome are some of the gastrointestinal system disorders. Dietary therapy for hiatal hernia is aimed at decreasing symptoms in patients who have reflux or esophagitis. Dyspepsia (indigestion) is a general term that is frequently used to describe common symptoms of upper gastrointestinal tract. The most common cause of gastritis and peptic ulcers is helicobacter pylori infection. It is responsible for chronic inflammation of the gastric mucosa, for gastric and duodenal ulcers, and for some forms of atrophic gastritis and gastric cancer. Dumping syndrome usually occurs as a result of a loss of normal regulation of gastric emptying and systemic responses to a meal. Progress in the medical management of gastrointestinal disorders has mostly eliminated the need for this strict level of medical nutrition therapy. Today, nutritional therapy for patients with upper gastrointestinal system disorders is more specific for a patient, and far more effective than in the past.
