How effective is GP consultation for threadworms?

Threadworms are small intestinal worms that can cause itching around the anus, often worse at night. A GP may ask about night-time itching, disturbed sleep, visible worms and whether other people at home have similar symptoms. The diagnosis is often based on the history and appearance rather than a routine stool sample, although the GP will consider other causes of itching when the picture is unclear.

The consultation helps match treatment advice to the person affected, household members, age and pregnancy or breastfeeding status. Hygiene matters because eggs can spread from hands, clothing, bedding and shared surfaces, allowing infection to return after treatment.

Wash hands carefully after using the toilet and before eating, keep fingernails short, shower in the morning, change underwear daily and wash sleepwear, towels and bedding regularly. Clean frequently touched bathroom surfaces and avoid shaking bedding. Follow the GP or pharmacist's directions about treatment and household members, and ask before treating a young child or anyone who is pregnant.

Arrange a GP consultation if itching persists after advised treatment, keeps returning, the diagnosis is uncertain, or symptoms are affecting sleep. Seek prompt advice for severe abdominal pain, vomiting, blood in the stool, marked weight loss, or a child who seems unusually unwell. These features may need assessment for another problem.

Ask who in the household needs treatment, when treatment should be repeated if advised, how long to continue hygiene measures, whether a test is needed, and what symptoms would suggest another cause.
