On the flipside, having a disrupted estrobolome (the group of gut bacteria responsible for helping the body get rid of excess oestrogen) can also lead oestrogen levels to rise. This is because the excess oestrogen that isn’t ‘dumped’ in the detoxification process is reabsorbed into the bloodstream, leading to an imbalance.

Other factors which have been linked to high oestrogen include having low magnesium levels (magnesium helps the liver, which plays a role in removing excess oestrogen, to function properly) and eating too little fibre.

“Other causes of excess oestrogen include obesity, medications such as HRT, insulin resistance, polycystic ovarian syndrome, having an adrenal or ovarian tumour and a genetic condition called familial hyperestrogenism,” Phadnis adds.
