Heterophyes infection is a parasitic disease brought on by the tiny intestinal fluke Heterophyes heterophyes. Asia, Africa, and the Middle East are just a few of the regions throughout the world where this parasite can be found. Consuming seafood that is contaminated with heterophyes and is either raw or undercooked is a typical way to contract the disease.

Although heterophyes is very uncommon, people who are afflicted can experience serious symptoms. For the management of the infection and the prevention of its consequences, prompt diagnosis and treatment are essential.


Heterophyes is the only species of small intestinal fluke known to cause Heterophyes infection. However, depending on the degree of parasite invasion and the host’s immunological response, several infection types or stages may manifest.

  • Acute Heterophyes infection. The initial stage of the illness, which develops soon after consuming tainted raw or undercooked seafood. At this phase, symptoms like nausea, diarrhea, and abdominal pain are possible.
  • Chronic Heterophyes infection. An acute infection is untreated or endures for an extended period of time. Even if the symptoms are minimal, they may occur, including abdominal pain, exhaustion, and sporadic diarrhea.
  • High Heterophyes infection. This kind of infection happens when the small intestine is heavily infested with parasites. In children, a severe infection can cause anemia, impaired nutrient absorption, and developmental retardation.
  • Asymptomatic Heterophyes infection. In certain situations, people with Heterophyes may not show any symptoms at all, and the infection may only be discovered by chance during a regular stool test.


Heterophyes infection can cause a range of symptoms, which can vary depending on the severity and duration of the infection. Some individuals may not experience any symptoms at all, while others may develop more severe symptoms. Common symptoms of Heterophyes can include:

  • Abdominal pain
  • Diarrhea, which may be intermittent or persistent
  • Nausea and vomiting
  • Loss of appetite
  • Fatigue
  • Weight loss
  • Malnutrition
  • Anemia (low red blood cell count)
  • Itching and rash (in rare cases)


Heterophyes is normally diagnosed using a combination of clinical assessment, stool analysis, and occasionally imaging investigations.

  • Clinical evaluation
  • Stool examination
  • Imaging investigations

If you think you have a Heterophyes, get medical attention immediately for an evaluation and treatment. If the infection is not treated, it may result in consequences such as starvation, anemia, and child growth retardation.


Anti-parasitic drugs, such as praziquantel, are commonly used to treat Heterophyes, with the dose and duration determined by a medical professional.
