Early detection of a parasitic worm infection is crucial for effective treatment. Common symptoms include unexplained weight loss, fatigue, abdominal pain, diarrhea, and itching around the anus. Some people may experience nausea, bloating, or visible worms in stool. Blood tests or stool examinations confirm the diagnosis. Maintaining hygiene, washing hands, and avoiding contaminated food or water reduce infection risk. For treatment, Nizonide 500 mg (nitazoxanide) is often prescribed to eliminate intestinal parasites effectively. Trusted nizonide 500 mg distributors provide authentic medication for safe use. Always consult a doctor before starting treatment to ensure proper dosage and medical supervision.
