What is giardia?

Page last updated 07 July 2020

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, and nausea– which can last for several weeks.
