Most people infected with ascariasis have no signs or symptoms. Moderate to heavy infestations cause various signs or symptoms, depending on which part of your body is affected. In the lungs After you swallow the tiny (microscopic) ascariasis eggs, they hatch in the small intestine and the larvae migrate through the bloodstream or lymphatic system into the lungs. At this stage, you may experience signs and symptoms similar to asthma or pneumonia, including:  Persistent cough Shortness of breath Wheezing  After spending 10 to 14 days in the lungs, the larvae travel to the throat, where you cough them up and then swallow them. In the intestines The larvae mature into adult worms in the small intestine, and the adult worms typically live in the intestines until they die. In mild or moderate ascariasis, the intestinal infestation can cause:  Vague abdominal pain Nausea and vomiting Diarrhea or bloody stools  If you have a large number of worms in the intestine, you might have:  Severe abdominal pain Fatigue Vomiting Weight loss or malnutrition A worm in your vomit or stool
