How common is bedwetting in threadworms?

Threadworms live in the bowel and may move around the skin near the anus at night, causing itching and disturbed sleep. A child may scratch, wake often, or seem tired the next day. Bedwetting can occur alongside disrupted sleep, but it also has many other possible explanations. Look for itching around the bottom, restless nights, or visible small worms rather than relying on wetting alone.

Speak with a pharmacist or clinician about suitable treatment, especially for young children, pregnancy, or other medical conditions. Wash hands after using the toilet and before meals, keep fingernails short, wash sleepwear and bedding, and clean frequently touched bathroom surfaces. Treating household members may be advised because threadworms spread easily between people. Follow the product instructions carefully.

Arrange medical advice if itching persists after treatment, the diagnosis is uncertain, or there is abdominal pain, vomiting, weight loss, marked tiredness, or irritation from scratching. Seek urgent help for severe abdominal pain, repeated vomiting, faintness, or a child who appears seriously unwell.

Could threadworms explain the nighttime itching and wetting? Who in the household should be treated? When should treatment be repeated, and which hygiene measures are most useful?
