Intestinal worm infections may cause stomach pain, itching around the anus, bloating, nausea, poor appetite, weakness, or disturbed sleep. These infections commonly spread through contaminated food, water, unwashed hands, or walking barefoot in contaminated areas. Different worms may need different treatment approaches, although many mild infections respond well to common deworming medicines. Doctors often use medicines such as albendazole or mebendazole for routine intestinal worm infections because they help kill many common worms. The correct dose and duration depend on age, body weight, pregnancy status, liver health, and the type of worm involved. In some cases, repeat dosing is needed after a few weeks to reduce the risk of reinfection. Good hygiene, regular handwashing, trimmed nails, safe drinking water, and properly cooked food are important for preventing recurrence. Severe abdominal pain, vomiting worms, blood in stools, major weight loss, or persistent symptoms should be checked properly because some infections may require stool testing or different treatment.
