Symptoms of threadworms

Threadworms often go unnoticed by people who have them.

However, they can cause intense Pruritus ani (and the vagina in girls), particularly at night when the female worms are laying eggs. This can disturb sleep.

In some cases, you may spot threadworms on your bed clothes or sheets at night, or you may notice them in your stools. The worms look like threads of white cotton and are about one centimetre long.

Severe or persistent threadworm infections can cause:

• loss of appetite
• weight loss
• skin infection around the anus if bacteria enterany scratches caused by itching wearing cotton gloves while sleeping may help prevent this
• difficulty getting to sleep or staying asleep (insomnia)
• bedwetting

In very rare cases, threadworms can spread outside the intestinetothe urinary tract orliver, or the vagina or womb in girls or women.
