Parasitic worm infections (helminth infections) are caused by organisms such as Ascariasis, Hookworm infection, and Tapeworm infection. Symptoms vary by species and parasite load. Common signs include abdominal pain, diarrhea, nausea, vomiting, bloating, unexplained weight loss, fatigue, and anemia due to nutrient depletion. Some individuals experience anal itching, especially with pinworms, or visible worms in stool. Severe cases may cause intestinal obstruction, coughing (from larval lung migration), or malnutrition. Children are particularly vulnerable to growth delays. Early diagnosis and antiparasitic therapy often sourced through trusted nizonide whoesale suppliers are essential for effective management and prevention of complications.
