What are the symptoms of a tapeworm infection?

Most people who are infected do not have any symptoms. Those who have symptoms may experience nausea, weakness, loss of appetite, diarrhea, and abdominal pain. Young children, especially those with a heavy infection, may develop a headache, itchy bottom, or have difficulty sleeping. Sometimes infection is misdiagnosed as a pinworm infection.

Contrary to popular belief, a tapeworm infection does not generally cause weight loss. You cannot feel the tapeworm inside your body.
