The symptoms of candida in the gut overlap with many other conditions and imbalances, so it’s hard to know that your symptoms are down to candida overgrowth.
One study5 found that people with candida overgrowth in their small intestines—known as small intestinal fungal overgrowth (SIFO)—were much more likely to suffer from the following symptoms than people without SIFO:
Belching
Bloating
Indigestion
Nausea
Diarrhoea
Gas
However, many other conditions—like SIBO, parasite infection or H. pylori infection, for instance—can also cause these symptoms.
