Sometimes threadworm infection may not present with any particular symptoms and therefore may go unnoticed.
Common symptoms of threadworm infection include:
- Finding worms in your stools when going to the toilet or around the anal area. Worms may also sometimes be found on clothes worn at night or bedsheets.
- Intense itching around the anus (back passage) which gets worse at night – this is as the female threadworms lay their eggs around the anus at night
- Itching which keeps you up at night
You should see your GP if you develop other less common symptoms of threadworm infection, including:
- Finding large worms or large pieces of worm in your poo
- Red, itchy worm-shaped rash on your skin
- Sickness, vomiting, diarrhoea or a stomach ache for longer than 2 weeks
- Unexplained weight loss
