As a Functional Gut Health and Hormone Specialist, I’m always learning. There are new studies being released almost daily, and what we know is constantly changing. So a huge part of my job is keeping abreast of the latest developments in functional medicine.

I decided to put together this blog post with some of the most interesting research available to us. “The more you know”, and all that!

 

January 2022:

Many women have suspected it but finally there’s confirmation that Covid-19 vaccines may cause some small changes to the length of their menstrual cycles.

A study funded by the United States National Institutes of Health (NIH) found the length of a woman’s cycle was impacted by nearly one day on average after each dose of a vaccine, but it did not seem to impact the number of days of bleeding.

 

December 2021:

According to new research, hormonal IUDs do not have a purely local effect on the uterus – but, instead, affect the entire body. In other words, the contraceptive drug released by the IUD (levonorgestrel) travels to the breasts, brain, and other tissues. And importantly, levonorgestrel is NOT progesterone so acts differently in those tissues compared to progesterone. At the same time, hormonal IUDs can dramatically lighten flow and are arguably the gentlest type of hormonal birth control.
