The longest tapeworm ever removed from a human was 82 feet long, and was removed from a patient in India. The man had complained of abdominal pain for several months and had anemia.
A tapeworm is a parasite (Diphyllobothrium datum) that can live in the small intestine and has the ability to grow rapidly.
The parasite makes its way into the human body when a person eats raw or undercooked meat of an animal that had ingested tapeworm eggs. Some patients with tapeworms don’t have any symptoms at all, but tapeworms can cause abdominal pain, diarrhea, anemia, and even bowel obstructions.
About 20 million people in the world are infected with tapeworms. Tapeworms can live inside of a human for more than 25 years.
