What should you know about giardiasis hund?

The parasite lives in the small intestine and may interfere with digestion and absorption. Symptoms can begin after an exposure and may continue after the initial illness, particularly if dehydration or temporary difficulty digesting certain foods develops. A stool test can help confirm the infection; symptoms alone cannot identify the cause. Learn more about [Giardiasis](/conditions/giardiasis/), [Diarrhoea](/symptoms/diarrhoea/) and [Bloating](/symptoms/bloating/).

Take frequent sips of water or an oral rehydration drink, especially after loose stools. Eat small, simple meals if tolerated and wash hands carefully after using the toilet and before preparing food. Avoid preparing food for other people while you have diarrhoea. Arrange a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if symptoms persist, follow testing instructions, and take prescribed [Antibiotic Treatment](/treatments/medical-management/antibiotic-treatment/) exactly as directed.

Seek urgent medical help if you cannot keep fluids down, feel faint or confused, pass very little urine, or have severe or worsening abdominal pain. Prompt assessment is also sensible for a young child, an older adult, pregnancy, or a weakened immune system. Contact a clinician if diarrhoea continues, returns after treatment, or you notice blood in the stool.

Ask whether a stool sample is needed, how to prevent household spread, which fluids are suitable, and whether medicines or recent travel could change the treatment plan. Mention anyone else at home with diarrhoea.
