Crohn's disease is a disease of unknown causation.
Crohn's disease has a bimodal distribution in incidence as a function of age: the disease tends to strike people in their teens and twenties, and people in their fifties through seventies.
Inflammatory bowel diseases were described by Giovanni Battista Morgagni (1682-1771), by Polish surgeon Antoni Leśniowski in 1904 (leading to the use of the eponym "Leśniowski-Crohn disease" in Poland) and by Scottish physician T. Kennedy Dalziel in 1913.
Symptoms of gastrointestinaldisease are indigestion, heartburn, nausea, loss of appetite, abdominal pain that is often worse after eating, and gastrointestinal bleeding (signs of this are vomiting material that looks like coffee-grounds, or having dark stools).
Causes of gastrointestinaldisease are aspirin use, alcohol and tobacco use, poor diet (to many fried, fatty foods, sugar and refined foods), poor food combining, drinking with meals, over eating especially spicy foods, eating to fast or to often, food allergies, candida overgrowth, stress, serious illness.
Other causes of gastrointestinaldisease may be reflux injury (such as bile backing up into the stomach and esophagus, trauma (for example surgery, radiation, chemotherapy, severe vomiting and having swallowed a foreign object), bacterial, viral, fungal and parasitic infections, pernicious anemia and systemic disease for example (Crohn's) disease.
