Taeniasis is a bowel parasite caught from raw or undercooked meat. Abdominal pain and moving pieces in the stool may be seen. It can be treated with suitable medicines.
What is taeniasis (tapeworm infection)?
Taeniasis, commonly known as tapeworm infection, is an infection caused by a long, flat parasite that lives in the bowel. These parasites are called taenia or tapeworms.
How is it caught?
The infection is usually caught by eating raw or undercooked beef or pork that contains the parasite.
The parasite grows in the bowel and can reach several metres in length.
What are the symptoms?
Most patients have no obvious complaints. In some people, however, the following symptoms can appear:
- Abdominal pain or a feeling of discomfort
- Nausea and changes in appetite
- Diarrhoea or constipation
- Weight loss
- White, moving pieces of the parasite seen in the stool or in underwear
Important: white, moving pieces seen in the stool are one of the main signs of tapeworm infection.
How is it diagnosed?
The diagnosis is usually made by finding eggs or pieces of the parasite in the stool. Sometimes the stool may need to be examined several times.
Is there a treatment?
Yes. Tapeworm infection can be treated with medicine.
A suitable anti-parasite medicine is given according to the type of parasite and the patient’s condition. After treatment, the stool may be checked to make sure that the parasite has been cleared completely.
How can you protect yourself?
Cooking meat thoroughly, not eating raw or undercooked meat, and paying attention to hand hygiene are important for protection.
When should you see a doctor?
If you notice moving, white pieces in your stool, or you suspect tapeworm infection, you are advised to see a gastroenterologist.
Remember: tapeworm infection can usually be treated. Getting the right diagnosis and using the right medicine are important, however.
