Stomach Problems Due to Chronic Infections
Stomach pain, bloating, belching, gas and diarrhea, lasting for several weeks or months may result from chronic infection by parasites, bacteria or, rarely, viruses or yeasts. There is often no fever in these infections.
Intestinal parasites, like giardia or intestinal worms, may cause long term loose stools with mucus or blood and abdominal bloating. Pale skin and tiredness are due to iron-deficiency anemia caused by impaired iron absorption due to intestinal inflammation, and blood loss due to bleeding ulcers, or blood sucked by intestinal worms. Diagnosis is made by finding parasites by stool Ova & Parasites test. Treatment by anti-parasitic medications usually results in full recovery in few days. Infection may recur if it was not completely treated or if source of parasites (pets, food or water poisoning) still exists.
