Gastroenteritis Overview
Gastroenteritis is a condition that causes irritation and inflammation of the stomach and intestines (the gastrointestinal tract). Diarrhea, crampy abdominal pain, nausea, and vomiting are the most common symptoms.
Viral infection is the most common cause of gastroenteritis but bacteria, parasites, and food-borne illness (such as shellfish) can be the offending agent.
Many people who experience the vomiting and diarrhea that develop from these types of infections or irritations think they have "food poisoning," and they may indeed have a food-borne illness. Many people also refer to gastroenteritis as "stomach flu," although influenza has nothing to do with the condition.
Travelers to foreign countries may experience "traveler's diarrhea" from contaminated food and unclean water.
- The severity of infectious gastroenteritis depends on the immune system's ability to resist the infection. Electrolytes (these include essential elements of sodium and potassium) may be lost as you vomit and experience diarrhea.
- Most people recover easily from a short bout with vomiting and diarrhea by drinking fluids and easing back into a normal diet. But for others, such as infants and the elderly, loss of bodily fluid with gastroenteritis can cause dehydration, which is a life-threatening illness unless the condition is treated and fluids restored.

Crohn Disease Overview
Crohn disease is a chronic (slowly developing,
long-term) inflammation of the digestive tract. It can affect any part of
the digestive tract from the mouth to the anus but usually involves the terminal part of the small intestine, the beginning of the large intestine
(cecum), and the area around the anus. The inflammation causes uncomfortable and bothersome symptoms and may produce serious damage to the digestive tract.
Â
Crohn disease is sometimes called regional enteritis or ileitis. It and a similar condition called ulcerative colitis
are referred to together as inflammatory bowel diseases. These illnesses are known for their unpredictable flares and remissions.
Â
The inflammation usually starts in one or more areas of the mucosa that lines the inside of the intestines.
- The disease may invade deeper tissues of the
intestinal wall and spread to involve more areas of the bowel.
