Diphyllobothrium latum (fish tapeworm) infection is most commonly due to eating freshwater fish containing larvae. Fish tapeworm can grow to 15 meters in length. Symptoms are nonspecific abdominal symptoms, such as loss of appetite, heartburn, diarrhea, and nausea. Vitamin B12 deficiency can also occur, leading to macrocytic anemia and neurological symptoms such as muscle twitches.
Clonorchis sinensis is another worm transmitted by eating raw fish. The worms live in the gallbladder area, so complications can include bile duct stomes, gallbladder stones, and other gallbladder disease.
Flukes (Flatworms) are leaf-shaped worms that attach to the host using abdominal suckers. It usually begins its life cycle as snails, then as larvae they infect fish, vegetation, or humans. Flatworms can travel to lungs, intestines, heart, brain, and the liver. Eggs can cause inflammation by releasing toxins that damage tissues.
