Why do I poop more on my period? Hormonal changes and gut health

Feeling bloated, constipated, or running to the bathroom more often during your period? You’re not alone.

Many menstruating people experience digestive changes during menstruation, often referred to as period poops. These shifts in bowel movements are completely normal and tied to your menstrual cycle and digestion. In this post, we’ll explore the science behind period diarrhea, period constipation, and how your body reacts to hormonal changes – plus tips to feel better naturally.

What are period poops?

“Period poops” describe the changes in bowel movements during menstruation. These can include:

Pooping more during your period;
Loose stools or period diarrhea;
Constipation before or after your cycle;
Cramping or pain during bowel movements.

These symptoms are common, yet rarely talked about. That’s why we’re here to normalize the conversation and support your menstrual wellness.

The science behind it: hormones and digestion

Your digestive system is influenced by hormonal fluctuations throughout your cycle. Two key players are prostaglandins and progesterone:

Prostaglandins help the uterus contract to shed its lining. But they can also affect the intestines, causing them to contract more – leading to digestive changes during your period, like diarrhea or more frequent pooping.
Progesterone slows digestion and can cause period constipation, especially in the days leading up to menstruation.

If you live with IBS or other gut conditions, these symptoms may be more intense. Understanding the link between hormonal changes and digestion can help you manage your cycle more effectively.

Why does pooping hurt on your period?

Painful bowel movements during menstruation can be caused by:

Uterine contractions affecting nearby organs;
Inflammation from prostaglandins;
Hard stools due to slowed digestion.

These symptoms are part of the broader spectrum of menstrual symptoms nobody talks about, but they deserve attention and care.

How to relieve period poops naturally?

Here are some gut-friendly period tips to ease discomfort:

Eat fiber-rich foods for menstrual health like fruits, veggies, and whole grains;
Stay hydrated to soften stools;
Limit caffeine and processed foods, which can worsen period bloating and gut health;
Try a period cup – many users report less bloating and cramping compared to tampons.

Talking about pooping more during your period shouldn’t be taboo. These are natural, hormonal shifts that affect your body every month. By understanding your menstrual cycle and digestion, you can make informed choices – whether that’s adjusting your diet, switching to a sustainable menstrual care routine, or simply giving yourself grace.
