Chiropractic and the Menstrual Cycle

There are many things that our clients come back to us and say “It might be a coincidence but since we’ve started care I’ve noticed ….”. One of the most common endings to that sentence that I hear is “…my menstrual cycle has been regular” or “I barely had any pain with my period this month”. I found this really interesting when I first started because I really didn’t realise how many people have problems with their menstrual cycle. Some might normalise the irregularity and pain some might get really worried about it.


There is no doubt that there is a high percentage of women on some form of hormonal contraception and one of the things I’ve noticed is that most of the period related comments I have received, have come from women who after deciding to stop their form of contraception, never regained a controlled cycle thereafter.

Why do so many women notice these changes once they’ve started chiropractic care?

There are not many studies that have looked into this subject but based on the knowledge we have of the nervous system we could put it down to a couple of different factors:


  1. Regulating the sympathetic and parasympathetic nervous system. If you haven’t heard of these words before, the sympathetic is what you would of heard of as fight, flight and survive response, and parasympathetic is the rest, digest and repair response. These two systems need to be balanced and work in harmony. They are each responsible for regulating production of different hormones which are obviously important for the menstrual cycle to occur. Therefore if the sympathetic and parasympathetic systems aren’t working efficiently, or in other words, if your body is under stress, these hormones will not be regulated accordingly. Through chiropractic care we rebalance the function of these two responses and your body takes care of the rest.


  1. Removing interference from the nerves that directly innervate our reproductive system. The uterus is supplied by different nerves some of them come from your mid-back and other from your low back (sacrum). If these nerves are not functioning at their best due to misalignments or more serious issues, then your brain and nervous system will not have full control over the uterus. Chiropractic care identifies these areas in the spine which are creating neurological interferences and your body can then start functioning much better.

What is normal?

As we know many things can have an effect on someone’s menstrual cycle, stress levels, contraceptive methodologies, hormone regulation, other conditions like endometriosis or PCOS and many other factors, therefore there are many ways to tackle this subject varying from chiropractic adjustments to supplement intake and dietary changes.


This is to let some of the lovely ladies reading this, know that you shouldn’t normalise your period pain or irregularity, but that maybe there are some things that can be looked into. By no means do I intend to say that your cycle should last 28 days on the dot, there is always wiggle room. I am also not saying that chiropractic can help for certain in every case but I am always surprised at the long term changes that our clients notice when coming in regularly for maintenance care, and how they notice things go downhill again if for some reason they take a break from chiropractic care.


If you know anyone who might have any menstrual cycle problems and that might benefit from reading this, send them the link to this blog or get them to book a phone call/screening with me to see if we can help.


Ciao for now :)
