Liver fluke infections can cause abdominal pain, nausea, vomiting, diarrhea, fever, hives, poor appetite, and weight loss. These parasitic worms are ingested through raw or undercooked fish and can obstruct the biliary system. Some people may have no symptoms.
A liver fluke infection, which is an infection by parasitic worms called flukes, can cause a variety of unpleasant symptoms. Among the most common are abdominal pain, nausea, vomiting and diarrhea. A person with this condition may also develop a fever and generally feel unwell. Some people may also notice hives, poor appetite, and unexplained weight loss when they have a liver fluke infection. It is important to note, however, that some people experience no symptoms when they have liver fluke infections.
When a person has this type of infection, their body has become infected with flukes, which are parasitic worms ingested when certain types of raw or undercooked fish are eaten. Symptoms do not always develop with this condition. When they develop, however, they typically include abdominal pain in the part of the abdomen that houses the liver, the upper right side. This symptom typically results from the movement of the parasitic worms from the intestine to the liver and their subsequent lair in the patient’s liver. A patient may also experience abdominal pain when flukes periodically obstruct the biliary system, which is responsible for the creation, storage, and movement of bile.
An individual may also develop fever related to liver fluke infection. Often, a fever develops when a person is initially infected and during the early stages of the infection. Sometimes a person may also develop fevers during times when flukes obstruct the biliary system.
In many cases, a person with a liver fluke infection also experiences gastrointestinal symptoms such as nausea, vomiting, and diarrhea. These symptoms of liver fluke infection frequently develop during the early stages of the infection, and some patients may experience them for months after the onset of the infection. After the first few months of the infection, a patient may experience relief from these symptoms. They can return, however, due to inflammation caused by the flukes or their obstruction of the biliary system.
Sometimes a patient may also develop hives as a symptom of liver flukes. This occurs when the immune system recognizes the flukes as foreign invaders and causes an allergic reaction. Similarly, poor appetite, weight loss, and a general feeling of being unwell may also develop as signs of a liver fluke infection. Malaise often occurs in the early stages of the infection, but can also occur later, especially if the flukes cause permanent damage to the patient’s liver. Appetite and weight loss are more common with long-term infection.
