SIBO Breath Test (Hydrogen + Methane)

ABOUT THIS TEST 

The SIBO breath test is a simple, non-invasive test used to check for bacterial overgrowth in the
small intestine. It works by measuring gases (hydrogen and methane) in your breath after taking
a test drink.

SIBO can contribute to bloating, trapped gas, discomfort, constipation, diarrhoea, or IBS-type
symptoms.

Suitable for individuals with persistent bloating, gas, IBS symptoms, or unexplained digestive
disruption.
