Introduction
After infection with liver flukes, symptoms generally appear after a certain incubation period, which varies from person to person and typically ranges from two weeks to five months. Therefore, if you suspect a liver fluke infection, you should seek medical attention promptly for diagnosis and treatment. It is important to maintain good food hygiene in daily life to prevent infection, and it's best to avoid consuming raw fish whenever possible.
After infection with liver flukes, symptoms generally appear only after a certain period of time, which varies from person to person and typically ranges from two weeks to five months.
When humans ingest freshwater fish or shrimp contaminated with liver fluke larvae, the larvae hatch in the intestines, penetrate the intestinal wall, migrate into the liver, and begin parasitic growth. This process damages liver tissue, causing conditions such as liver inflammation and fibrosis, and symptoms may develop as early as two weeks after infection.
Some individuals with liver fluke infection may not experience obvious symptoms during the early parasitic stage. However, as the number of parasites increases, symptoms such as abdominal pain, diarrhea, weight loss, and hepatomegaly (enlarged liver) may appear after about five months.
Treatment involves taking antiparasitic medications such as praziquantel tablets or albendazole tablets under medical supervision. If complications such as cholangitis occur, antibiotics like clindamycin tablets, ceftazidime tablets, or imipenem tablets may be prescribed by a doctor.
Therefore, if you suspect a liver fluke infection, seek prompt medical evaluation and treatment. Maintain good food hygiene practices to prevent infection, and avoid consuming raw fish, such as sushi or sashimi, whenever possible.
