How common is abdominal pain in threadworms?

Threadworms are small intestinal worms that commonly cause itching around the anus, often more noticeable at night. Restless sleep and irritation can follow. Some people also have abdominal discomfort, but this symptom is not specific to threadworms. The tiny white worms or eggs may sometimes be noticed around the anus or on bedding, which can help a clinician decide whether testing is needed.

Speak with a pharmacist or clinician if threadworms are suspected, particularly for a young child, pregnancy, breastfeeding, or a person taking regular medicines. Treatment advice may include a medicine and household hygiene measures to limit spread and reinfection. Careful handwashing, short clean fingernails, regular washing of sleepwear and bedding, and cleaning shared surfaces are practical measures. Follow the exact instructions given for everyone in the household.

Seek medical advice for persistent abdominal pain, weight loss, fever, vomiting, diarrhoea that does not settle, blood in stool, or symptoms that do not improve after advised treatment. Get urgent care for severe or worsening pain, a swollen or rigid abdomen, fainting, or difficulty keeping fluids down. Such features need assessment regardless of whether threadworms are present.

Ask how threadworms can be confirmed, whether treatment is suitable for everyone at home, and which hygiene measures matter most. Also ask whether the abdominal pain could have another cause and which warning signs should prompt a further review.
