What Are Symptoms of Having a Tapeworm?

Some of the symptoms of having a tapeworm include nausea, abdominal pain, diarrhea, fatigue, weight loss, hunger or loss of appetite, according to WebMD. Often there are no symptoms of a tapeworm infection.

In rare cases, a tapeworm may cause serious conditions, such as blocking the intestine, according to WebMD. Depending on the type, the tapeworm may even migrate to other parts of the body, such as the eyes, brain and liver.

If a person suspects a tapeworm infection, a doctor should be consulted. The doctor may collect a stool sample to determine which kind of tapeworm, if any, is present. If worms are not detected in the stool, the doctor may order blood tests to check for antibodies produced by the body to fight the tapeworm infection. The doctor may also utilize computerized imaging, such as an MRI, to check for tapeworm damage in other areas of the body.
