Parasites are generally not found in the stomach because the strongly acidic environment in the stomach is not conducive to parasite survival.
Parasites of the digestive system are mostly found in the intestines and biliary system, for example, adult parasites of roundworm, Giardia lamblia, hookworm, pork tapeworm, beef tapeworm, etc. are mostly found in the small intestine; amoebas of dissolved tissue are mostly found in the colon of human beings; and adults of the Chinese testicular schistosome, i.e., the liver schistosome, are mostly found in the intrahepatic bile ducts.
The digestive tract is a common site for parasites to invade the human body, and patients may have clinical symptoms such as fever, diarrhea, anemia, malnutrition, etc. Sometimes adult parasites or eggs can be seen in the feces.
If there is a history of unclean diet, travel history in endemic areas and other epidemiological information and the corresponding clinical symptoms, please go to the regular hospital for consultation.
