Flies, also known as flies, after eating flies some people may not have obvious abnormal symptoms, and some people may experience acute gastroenteritis and other conditions. After eating the fly, the stomach acid can break down the fly and the parasites it carries, and the bacteria it carries can be removed by the body’s immune system, so there will be no abnormal clinical manifestations in such cases. However, if the body’s immune system is weak and the stomach acid does not completely break down the fly and the parasites it carries, acute gastroenteritis may occur, followed by abdominal pain, diarrhea, nausea, vomiting and other symptoms. If you experience any discomfort after eating the fly in your stomach, it is recommended that you go to the hospital.
