Which are the symptoms of Fasciolosis?

Fasciolosis, also known as liver fluke infection, is a parasitic disease caused by the ingestion of Fasciola hepatica or Fasciola gigantica, commonly known as liver flukes. These flatworm parasites primarily affect the liver and bile ducts of various mammals, including humans. The symptoms of fasciolosis can vary depending on the stage of infection and the severity of the disease.

Acute Phase:

The initial phase of fasciolosis is the acute phase, which typically occurs within a few weeks of infection. During this stage, individuals may experience:

• Abdominal pain: Pain in the upper right quadrant of the abdomen is a common symptom. It may be dull or colicky in nature.


• Fever: Low-grade fever is often present, accompanied by chills and sweating.


• Malaise: Generalized weakness, fatigue, and a feeling of being unwell are common.


• Loss of appetite: Individuals may experience a decreased desire to eat, leading to weight loss.


• Nausea and vomiting: Some individuals may experience episodes of nausea and vomiting.


• Hepatomegaly: Enlargement of the liver can occur, leading to tenderness and discomfort in the right upper abdomen.

Chronic Phase:

If left untreated, fasciolosis can progress to the chronic phase, which may last for months or even years. The chronic phase is characterized by:

• Chronic abdominal pain: Persistent or intermittent pain in the upper right abdomen is a common symptom. It may be accompanied by bloating and discomfort.


• Jaundice: In some cases, the skin and whites of the eyes may turn yellow due to liver dysfunction.


• Ascites: Fluid accumulation in the abdominal cavity can occur, leading to swelling and distension.


• Unexplained weight loss: Chronic fasciolosis can cause ongoing weight loss and malnutrition.


• Anemia: The presence of liver flukes can lead to chronic blood loss, resulting in anemia.


• Allergic reactions: Some individuals may develop allergic responses, such as skin rashes, itching, and hives.


• Hepatic fibrosis: Prolonged infection can cause scarring and fibrosis of the liver, potentially leading to liver cirrhosis.

If you suspect you may have fasciolosis or are experiencing any of these symptoms, it is important to seek medical attention promptly. A healthcare professional can perform diagnostic tests, such as blood tests and imaging studies, to confirm the diagnosis and provide appropriate treatment.
