Their immune systems may be less effective, leading to prolonged symptoms. Additionally, existing health conditions can complicate recovery, making them more susceptible to complications.

How does giardiasis affect children?

Children with giardiasis may experience more severe symptoms like diarrhea and dehydration compared to adults. Their developing immune systems and smaller body size make them more vulnerable to fluid loss. Children may also have difficulty communicating symptoms, leading to delayed treatment and increased risk of complications.

How does giardiasis affect pregnant women?

Pregnant women with giardiasis may experience more severe dehydration due to increased fluid needs. The infection can lead to nutritional deficiencies, affecting fetal development. Hormonal changes during pregnancy can also alter immune responses, potentially worsening symptoms. Prompt treatment is crucial to protect both mother and baby.

Diagnosis & Monitoring

How is giardiasis diagnosed?

Giardiasis is diagnosed by testing stool samples for the Giardia parasite. Symptoms like diarrhea, stomach cramps, and nausea support the diagnosis. The stool test, which detects the parasite or its antigens, is the primary diagnostic tool. In some cases, multiple samples may be needed to confirm the infection.

What are the usual tests for giardiasis?

The most common test for giardiasis is a stool test, which detects the Giardia parasite or its antigens. This test confirms the diagnosis and guides treatment. In some cases, multiple stool samples are needed for accuracy. Imaging studies are not typically used for diagnosis.

How will I monitor giardiasis?

Giardiasis is monitored by observing symptoms like diarrhea and abdominal pain. Improvement is noted when symptoms decrease. Stool tests can confirm the presence of the Giardia parasite. Monitoring frequency depends on symptom severity and treatment response, often requiring follow-up tests after treatment to ensure the infection is cleared.

What are healthy test results for giardiasis?
