What is giardia?

Page last updated 28 February 2019

Giardia is a protozoan parasite – a single-celled organism that causes gastroenteritis (or gastro). It is a cause of chronic diarrhoea in travellers, and the most commonly acquired parasite infection. The parasite Giardia duodenalis lives in the bowel and can cause diarrhoea, gas, stomach cramps, nausea and vomiting – which can last for several weeks.
