Study, 2022
Do women with PMS have different gut bacteria?
Yes. Women with PMS have clearly different gut bacteria compared to women without PMS. They have much higher levels of certain bacteria, especially one called Collinsella, approximately 4.5 times higher.
What they did
Researchers compared gut bacteria from stool samples of 24 Japanese women with PMS to 144 Japanese women without PMS, analyzing the bacterial composition.
What they found
The PMS group had clearly different gut bacteria compared to the control group. Three types of bacteria were higher in the PMS group: Collinsella (approximately 4.5 times higher than the control group), Bifidobacterium, and Blautia. Collinsella showed the strongest link to PMS in women aged 30-40 years.
What it means for you
The bacteria living in your gut may be related to PMS. Since diet affects gut bacteria, changing your diet might help improve PMS. However, we do not know whether these bacteria cause PMS or if PMS causes these bacterial changes. This was a relatively small study and needs to be confirmed with larger research.
