What Are the Symptoms of Worm Infections?

Worm infections (intestinal helminths) can cause a range of gastrointestinal and systemic symptoms, depending on the species and parasite load. Common signs include abdominal pain, bloating, diarrhea, nausea, vomiting, and unexplained weight loss. Patients may experience anal itching (especially with pinworms), fatigue, anemia (notably with hookworms), and visible worms in stool. In children, symptoms can include irritability, poor growth, and impaired cognitive performance. Some infections also cause cough or wheezing during larval migration. Early diagnosis through stool examination is important. Treatment typically involves antiparasitic agents such as mebendazole; however, sourcing medications like mebendazole wholesale should follow proper medical and regulatory guidelines.
