what can a tapeworm do to a human
Tapeworms do not have intestinal tracts: they absorb partially digested substances from their host through their skin. Adult tapeworms can live in the digestive tracts of a variety of hosts such as humans, pigs, cows, dogs, cats and fish. Most tapeworms have both male and female reproductive organs, and reproduce and fertilize their own eggs.
It can take months or years to notice any signs of a tapeworm. They can include: mild nausea; diarrhea; abdominal pain; loss of appetite; weight loss; Sometimes, a person can feel a piece of the worm coming out through the anus or see it in their feces. There are different types of tapeworm. One (fish tapeworm) can cause anemia because it absorbs vitamin B12, which helps make red blood cells.
