What is period poop?

Right, so what are period poops?

While infamous PMS symptoms like cramps and mood swings often get the limelight, period poops are, um, not to be sniffed at.

If you need to go a lot more frequently, or your poop appears to have changed consistency for the occasion, you are not alone.


Period poops occur when our gastrointestinal systems interact with the hormonal shifts of our menstrual cycles.

And it’s common for this to happen.

At least 73% of the participants in this study experienced some sort of tum trouble either before or during their periods.

So what causes this? Here’s the lowdown.

Why do I poop so much during my period?

The key player here is a group of compounds in your body called prostaglandins.

Prostaglandins act like hormones but are not technically the same.

That’s because, rather than being released from a particular gland and traveling around the body, they’re made right where they’re needed.

This on-site production happens in nearly all our cells, making prostaglandins a key feature in your body’s response to injury and illness.

But hold on. What do prostaglandins have to do with period poop? As it turns out, a whole lot.

Prostaglandins help you shed the lining of your uterus during your period by causing the muscles and blood vessels in the area to relax and contract.

The thing is, they are also pretty good at relaxing other things — including your bowels.

So, your food may move through you a bit quicker than usual, resulting in period diarrhea.

Prostaglandin levels are high on the first day of your period and just before.

As that lining sheds, they drop.

So you may notice that your symptoms get less dramatic as your period progresses.

Why does it hurt to poop on my period?

And then you may have to contend with the other end of the spectrum — period constipation.

A possible culprit here could be the hormone progesterone.

During your menstrual cycle, progesterone helps prepare your body for pregnancy by thickening up the lining of your uterus.

But it also may have another effect — slowing down your digestive system.

This can cause a few digestive issues before your period, including constipation and gastroesophageal reflux (GERD).

Know that you don’t have to struggle with uncomfortable symptoms alone.

Full permission to talk to your doctor. This is important on two fronts.

For one, they’ll be able to treat your symptoms.

And, two, they’ll check that nothing else is up.

Period poop (and other digestive issues around this time) can be worse for people who struggle with digestive problems like irritable bowel syndrome (IBS) and Crohn’s disease.

How can I treat period poop?

Things that might make period poop and constipation easier to deal with?

  • Stool softeners for constipation
  • Pain relievers like ibuprofen for painful poops and cramps
  • Hormonal contraception

It’s also good to keep well-hydrated, especially if you’re experiencing diarrhea.

And to steer clear of any foods that make you feel worse.

Limiting your caffeine and alcohol intake can help right now.

Can you poop with a tampon in?

This is an important question, especially if those bowel movements are coming more frequently than usual.

The good news is, it’s up to you.

You can poop with a tampon in.

But you might lose it — especially if you’re doing a little extra pushing.

The only important rule here?

Change your tampon if any poop gets on the string.

The bacteria from your poop could get into your vagina and upset the balance there.

This could put you more at risk of an infection called bacterial vaginosis, where “bad” bacteria outnumber the “good.”

Other than that, the choice is yours.
