Abdominal pain, constipation, and diarrhea, can occur with diverticulosis, which then may be called diverticular disease.
Diverticulosis can be diagnosed with barium X-rays, sigmoidoscopy, colonoscopy, or CT scan.
Treatment of diverticulosis can include high fiber diet, and anti- Read More
- Enterovirulent e. coli (eec)
Enterovirulent E. coli (EEC) facts

EEC bacteria can cause a wide range of symptoms ranging from mild to bloody diarrhea, nausea, vomiting, stomach cramping and dehydration. Different groups often produce less (EAEC group) or more intense symptoms (EHEC group) Read More
- Gastroenteritis (stomach flu)
The stomach, small intestine and large intestine (colon) are part of your digestive tract, which processes the foods you eat. Viral gastroenteritis is an inflammation of these organs caused by a virus.
Although it's commonly called stomach flu, gastroenteritis isn't the same as influenza. The flu (influenza) affects only your respiratory system — your nose, throat and lungs. Gastroenteritis, on the other hand, attacks your intest Read More

After you eat roundworm (trichinella) larvae, they grow into adult worms in your small intestine. The adults then produce larvae that move through the bloodstream to muscle tissues, shown here.
Signs and symptoms of trichinosis infection and how severe the infection is can vary. This depends on the number of larvae eaten in the infected meat.
Possibly no signs or symptoms
Mild cases of trichinosis — those with onl Read More

The colon is the part of the digestive system where water is removed from undigested material, and the remaining waste material is stored. The rectum is the end of the colon adjacent to the anus. In patients with ulcerative colitis, ulcers and inflammation of the inner lining of the colon lead to symptoms of abdominal pain, diarrhea, and rectal bleeding.
