Symptoms
Many Strongyloides infections are mild and go unnoticed. Moderate infections may cause a burning pain in your abdomen. You may have nausea and vomiting and alternating diarrhea and constipation. Severe infections result in anemia, weight loss, and chronic diarrhea. Strongyloidiasis in severely immunocompromised people can cause a variety of symptoms, including an ARDS-like pneumonia (Acute Respiratory Distress Syndrome).
