Why Do I Have Diarrhea During My Period?

You’ve been there. . .feeling tired, gross and down right yucky on your period, only to have it accompanied by many trips to the bathroom because suddenly you’ve got the shits! Way to kick a girl when she’s down. . .
I never understood why I would experience this for one or two days at the start of my period. The combination left my pelvis feeling raw and seriously unhappy. 
Happily, I’ve discovered the unknown causes and some secret remedies just for you (and me). 




Prostaglandins are hormone-like substances that participate in a wide variety of functions in your body including muscle contraction and relaxation, modulating inflammation, regulating blood pressure, and dilating and constricting blood vessels.  Where they differ from actual hormones is that they are not produced in a gland and sent out into your body, rather your body makes them at the needed site. Pretty freaking cool- unless this turns into diarrhea. 
Prostaglandins are gut-muscle regulators and regulators of both ovulation and your menstrual cycle. This is where the connection begins. Having too many prostaglandins in production because of your internal inflammation brings extra bodies to the site- and some may get made in neighbouring areas- namely your uterus and colon. 
The prostaglandins seem to be involved whether or not you have a pre-existing digestive complaint like Irritable Bowel Syndrome or Inflammatory Bowel Disease. An interesting thing to note is that the shits and tears you experience during your period may be connected  as well! 

Fixing It

First of all, you want to think about doing something to regulate those prostaglandins so they’re not going haywire making you a toilet slave. 
Oftentimes an imbalance in Omega 3 and Omega 6 fatty-acids can create this. Many of us do get WAY too much Omega 6 from our diet…processed foods, trans fats and rancid fats, poor quality meat and other foods are the culprits. This all equals big time INFLAMMATION. 
Not only this, but regulating your hormones is an important part of getting rid of this problem. The more your hormones are struggling to function (or over-functioning) the bigger your poop problems can be. Reducing overall PMS by detoxifying dominant estrogen, balancing cortisol and regulating insulin are key to this.



Enjoy a high-variety anti-inflammatory diet to achieve best results in pooping smooth, all month long. 


  • A rainbow of produce- from the richest reds and purples to the darkest greens.
  • Two to three delectable (BIG) servings of green vegetables like kale, collard greens, broccoli, green beans, spinach, parsley, cilantro, romaine, mesclun greens, rapini, zucchini, green peppers, cucumber, mustard greens, turnip greens, beet greens, swiss chard, and sprouts 
  • Sumptuous (pre-soaked or sprouted when possible) gluten-free grains and bread, like quinoa, millet, buckwheat or amaranth
  • Divine dairy-free nourishment like coconut milk, almond milk, coconut kefir, coconut yogurt and savoury cashew ‘cheeses’
  • Satisfying yummies full of omega 3 fatty-acids like chia + hemp seed, flaxseed, salmon, mackerel, sardines, and other oily fish, and dark leafy green shit
  • Small amount of unrefined sweeteners like raw honey, grade B maple syrup, coconut sugar or blackstrap molasses




All that nasty junky food I mentioned at the beginning of this post causes your organs to go on strike. It becomes too flipping hard for them to constantly metabolize and eliminate the barrage of stuff getting thrown at them. Your liver especially hates this and so results hormonal imbalances. 
Solution? Cleanse your body of the bad, making way for vibrant health, easy trips to the bathroom and no more period monster. 

Astringent Herbs

Acutely when you are experiencing diarrhea is where astringent herbs can be really helpful (also for excessive menstrual flow). While you’re working on the proactive long-term solution of detoxification, these herbs will come in handy. 
  1. Red Raspberry Leaf: An astringent herb to slow diarrhea and heavy flow, this herb is also a highly nutritive tonic to help you feel vibrant again. Makes a great tea!
  2. Meadowsweet: A great astringent herb that can be taken as tea to help nourish and calm the digestive tract to stop diarrhea quickly. 

Omega 3 Supplementation


There have been studies that show how rocking omega 3s are for your period problems. In one, after 3 months receiving a combined daily dose of 550mg EPA and 205mg DHA from fish oil, the amount of menstrual cramps, AND low back pain and abdominal pain. Sounds like a win-win to me!
