First, let’s take stock of what liver flukes are?
Liver fluke, also known as Clonorchis sinensis, adult worms resemble sunflower seeds in shape and size, parasitic in humans and mammals (cats, dogs, pigs, etc.) Human feces are excreted.
The first “home” of liver flukes is freshwater snails. After the eggs enter the freshwater snails, they grow and multiply into cercariae.
And then to the second “home” – freshwater fish and shrimp, which grow into cystic larvae, when people eat freshwater fish and shrimp that are not cooked.
Liver flukes can then develop into adults in their third “home” – the human body.
Liver fluke adult parasites live in the intrahepatic bile ducts of humans. Generally, the number of parasitic worms in a human body ranges from dozens to hundreds, and many can reach thousands. The pathogenic mechanism is mainly It is related to the mechanical obstruction and damage of the bile duct by the parasite.
In what ways can liver flukes be infected?
①Eat raw or half-raw freshwater fish and shrimp: Shunde fish, Chaoshan raw pickled, Jiangsu and Zhejiang drunk shrimp and other delicacies are all raw fish or shrimp dipped in condiments and eaten directly. It is fresh, and the liver fluke cysts in the fish and shrimp are also eaten in the stomach as they are.
②Fish porridge, grilled fish in the wild: These methods cannot guarantee that the fish is fully cooked, cannot kill the cystic larvae in it, and there is also a risk of infection.
③The chopping board and the kitchen knife are not well differentiated between raw and cooked: the kitchen knife or cutting board that has just cut the raw fish, bring it again Cut cooked food so that liver fluke cysts from raw fish may stick to kitchen knives or cutting boards, contaminating cooked food and causing liver fluke infection.
Can I use wine or Vinegar to kill insects?
This way you can enjoy delicious food and pass the level safely. Unfortunately, none of these methods are reliable.
To kill liver flukes with alcohol, the cysts of liver flukes need to be soaked in alcohol of more than 70 degrees for more than 24 hours. long time.
To kill liver flukes with vinegar or soy sauce, you need to soak the liver fluke cysts in vinegar for more than 2 hours and in soy sauce for more than 5 hours. Usually, the seasoning is not so long. .
The only reliable way is to make freshwater fish and shrimp fully cooked before eating. For the sake of health, you can only sacrifice a little appetite.
What are the symptoms of discomfort after liver fluke infection?
Mild infections have no symptoms or only discomfort after meals, fullness, decreased appetite, mild abdominal pain, and fatigue.
Generally infected patients will also experience fatigue, dull pain in the liver area, abdominal pain, diarrhea, and some patients are accompanied by systemic symptoms such as anemia, malnutrition, and edema.
Individual patients with severe infection developed obstructive jaundice and even biliary colic due to a large number of adult worms blocking the common bile duct.
Severely infected patients may have sudden chills, high fever, decreased appetite, dislike of greasy food, mild jaundice and other manifestations.
Severely infected children can experience malnutrition and growth retardation, and even dwarfism.
What are the adverse consequences of liver fluke infection?
Liver fluke infection can cause cholangitis, cholecystitis, and gallstones. Severe cases of chronic repeated infection can develop liver cirrhosis and even induce liver cancer.
used to eatHow do you know if you have liver fluke disease?
Hurry up and check:
① Blood test for liver fluke antibodies: negative can basically rule out, positive cannot distinguish past infection, current infection or false positive, further examination is needed to confirm the diagnosis .
②Excuse worm eggs in feces: it is the easiest, and the diagnosis is immediately confirmed, but when liver flukes do not lay eggs, they will not be detected, and the positive rate is relatively low. Increase the positive rate.
③ Duodenal fluid drainage inspection: Drainage of duodenal fluid under gastroscope to check the eggs, the diagnosis is immediately confirmed, and the positive rate is higher than that of fecal examination, which is relatively troublesome.
Knowing these common senses, if your friends have eaten raw fish, then go to the hospital for an examination. Once you find liver fluke infection, you need to go to a specialist for treatment as soon as possible.
