B70.0

Clinical Causes: Eating raw or undercooked freshwater fish that contains tapeworm larvae or adult worms. Consuming contaminated fish from lakes or rivers where the parasite is prevalent. Poor sanitation practices leading to contamination of freshwater sources with tapeworm eggs. Ingestion of undercooked fish from fish farms or wild-caught sources harboring the parasite.

Key Symptoms: Digestive discomfort such as nausea, diarrhea, or abdominal pain. Unexplained weight loss despite a normal or increased appetite. Weakness or fatigue due to nutritional deficiencies. Vitamin B12 deficiency symptoms like anemia, leading to weakness, pale skin, or numbness. Presence of segments of the tapeworm in stool, sometimes seen with the naked eye. Rarely, allergic reactions such as itching or skin rashes.

Diagnosis Path: Diagnosis typically involves stool tests to detect tapeworm eggs or segments. Sometimes, blood tests may reveal anemia or vitamin B12 deficiency associated with the infection. Imaging studies or endoscopy might be used in some cases to visualize the parasite if it is adult and visible within the digestive tract.

Treatment Protocols: Treatment generally involves antiparasitic medications such as praziquantel or niclosamide. These are effective in killing the adult tapeworm. In some cases, multiple doses or follow-up stool tests are necessary to confirm the eradication of the infection. Maintaining good hygiene and properly cooking fish are crucial preventive measures to avoid reinfection. Nutritional support may be needed if deficiencies occurred during the infection.
