The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus , stomach , and intestines .
The main symptom of gastroenteritis is diarrhea. Other symptoms may include: [citation needed] Abdominal pain or cramping. Nausea. Vomiting. Low grade fever. Because of the symptoms of vomiting and diarrhea, people who have gastroenteritis can become dehydrated quickly. It is very important to watch for signs of dehydration.
Gastroenteritis, also known as infectious diarrhea, is an inflammation of the gastrointestinal tract including the stomach and intestine. [8] Symptoms may include diarrhea, vomiting, and abdominal pain. [1] Fever, lack of energy, and dehydration may also occur. [2] [3] This typically lasts less than two weeks. [8]
Upper and lower human gastrointestinal tract. The esophagus (American English) or oesophagus (British English, see spelling differences; both / iː ˈ s ɒ f ə ɡ ə s, ɪ-/; pl.: (o)esophagi or (o)esophaguses), colloquially known also as the food pipe, food tube, or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach.
t. e. Gastroesophageal reflux disease ( GERD) or gastro-oesophageal reflux disease ( GORD) is a chronic upper gastrointestinal disease in which stomach content persistently and regularly flows up into the esophagus, resulting in symptoms and/or complications. [6] [7] [10] Symptoms include dental corrosion, dysphagia, heartburn, odynophagia ...
Herpes esophagitis. Herpes esophagitis is a viral infection of the esophagus caused by Herpes simplex virus (HSV). While the disease most often occurs in immunocompromised patients, including post- chemotherapy, immunosuppression with organ transplants [1] and in AIDS, [2] herpes esophagitis can also occur in immunocompetent individuals.
Megaesophagus may be caused by any disease which causes the muscles of the esophagus to fail to properly propel food and liquid from the mouth into the stomach (that is, a failure of peristalsis). Food can become lodged in the flaccid esophagus, where it may decay, be regurgitated, or maybe inhaled into the lungs (leading to aspiration pneumonia).
Stomach diseases include gastritis, gastroparesis, Crohn's disease and various cancers. [1] The stomach is an important organ in the body. It plays a vital role in digestion of foods, releases various enzymes and also protects the lower intestine from harmful organisms. The stomach connects to the esophagus above and to the small intestine below.
