What are period poops?

During your period you may have experienced a phenomenon known as “period poops”. One of the many physiological changes that can occur during the menstrual cycle, if you’ve ever found yourself on the toilet wondering “what are period poops?” you’ve landed in the right place. In this blog, we’ll reveal why period poo happens…

Understanding your menstrual cycle

Before we can dive into the topic of period poops, it’s essential to have a basic understanding of your menstrual cycle. The menstrual cycle involves hormonal fluctuations that prepare the uterus for potential pregnancy. During this cycle, the levels of oestrogen and progesterone rise & fall, this leads to changes in the lining of the uterus and subsequent shedding during menstruation. 

The digestive system & hormonal influence

Hormones play a significant role in regulating bodily functions, including the digestive system. The hormonal fluctuations during the menstrual cycle can have various effects on the gastrointestinal tract, leading to changes in bowel movements for some people. 


Prostaglandins are hormone-like substances that are involved in numerous physiological processes, including inflammation and the contraction of smooth muscles. During menstruation, the uterus releases prostaglandins, which help facilitate the shedding of the uterine lining. These prostaglandins can also affect the digestive system, leading to increased contractions in the intestine. These contractions can cause more frequent bowel movements and sometimes looser stools, commonly known as “period poops”

Water retention & bloating

Another common symptom of menstruation is water retention, leading to bloating in many people. This bloating can put pressure on the intestines, causing discomfort and changes in bowel movements. The increased pressure can lead to the sensation of needing to pass stool more frequently.

Hormonal imbalance & bowel movements

Hormonal imbalances, such as elevated levels of oestrogen & progesterone, can also impact bowel movements. High levels of oestrogen can slow down the digestive process, leading to constipation, while high levels of progesterone can have the opposite effect, resulting in looser stools. It’s fluctuations in these hormones throughout the menstrual cycle that can contribute to changes in bowel habits.

Pain & discomfort

Menstrual cramps, which occur due to the contraction of the uterine muscles, can also affect the digestive system. The pain signals from the uterus can cross over to nearby structures, such as the bowel, leading to discomfort and changes in bowel movements.
