Why Do I Poop More on My Period: Key Takeaways

• Period pooping is completely normal. It is common for women to experience changes such as frequent poops, loose stools, or diarrhea during their period due to hormonal shifts.
• Prostaglandins are the main reason you poop more on your period. These chemicals can speed up bowel movements and cause period-related diarrhea.
• Hormones like estrogen and progesterone affect digestion, causing constipation before your period and more frequent or softer stools once your period starts.
• Period stress and pain may intensify digestive symptoms, especially in women with IBS or sensitive stomachs.
• Diet changes before and during your period, like cravings for caffeine, chocolate, sugar, or greasy foods, can irritate the gut and worsen period poops.
• Lifestyle habits like reduced water intake, dehydration, or hormonal birth control can influence how much you poop during your cycle, sometimes triggering more frequent stools.
• Simple habits, such as reducing trigger foods, eating easy-to-digest meals, staying hydrated, using heat therapy, and tracking symptoms, can significantly reduce digestive discomfort. However, persistent or severe symptoms should be evaluated by a doctor.

Hormones: The Biggest Reason Why Do I Poop So Much On My Period

Prostaglandins and hormonal fluctuations, especially estrogen and progesterone, are the main reasons your bowel habits change during your period.

Prostaglandins are hormone-like chemicals that help your uterus contract, resulting in the shedding of its lining, causing a period. These contractions are what cause period cramps.

However, prostaglandins don’t always stay inside the uterus. Some amount of the chemical escapes into the bloodstream and reaches the intestines, causing symptoms like:

• More bowel movements
• Urgent poops
• Softer stools or diarrhea
• Cramping in the gut

In simple terms, prostaglandins make your gut contract just like they make your uterus contract, resulting in more period poops. [3]

Similarly, progesterone levels increase during the luteal phase before your period. This hormone slows down digestion. [4]

As a result, you may experience:

• Constipation
• Hard stools
• Bloating
• Sluggish digestion

Later, just before the period, the levels of both progesterone and estrogens drop. This shift may speed up digestion again, leading to:

• Frequent poops
• Loose stools
• Diarrhea
• Gas

So, both estrogen and progesterone could be responsible for why do I poop more on my period. These hormonal changes often lead to a typical pattern of constipation before periods, followed by frequent period poops.

Period Stress Triggers Gut Changes

If you are wondering, why does it hurt to poop on my period, here’s the answer: Hormonal changes during periods can trigger stress, mood swings, and anxiety.

Stress affects the gut through the gut-brain axis, causing more bowel movements, stomach discomfort, a “gassy” feeling, and digestive cramping. Women who experience anxiety-related stomach issues frequently often notice these symptoms getting worse around their period.

Period Pain Can Make Your Gut More Sensitive

If you are anxious to know, is it normal to poop a lot on your period, the answer is it depends on how your gut responds to hormonal changes and whether you have existing gut issues.

Your body is already dealing with inflammation and cramping during menstruation. This makes your intestines more sensitive than usual. In addition, if you already have IBS, food sensitivities, acid reflux, or a sensitive stomach, your symptoms may flare up during your period.

You Might Eat Differently Before or During Your Period

Hormonal shifts during your period can affect your cravings and appetite. Many women eat more sugar, caffeine, salty snacks, greasy food, chocolate, and carbs before and during their period, often to relieve stress. These foods can irritate your digestive system and make you poop more.

For example, caffeine stimulates the colon, increasing poops, while salt leads to water retention, increasing bloating. Similarly, sugar and chocolate can irritate the gut, causing loose stools, and greasy foods may cause cramping and digestive urgency.

This suggests that the food you eat could be the reason why are period poops so bad.

You Drink Less Water While Losing Fluids

During your period, you lose blood, water, and electrolytes. Plus, many women drink less because they feel bloated.  

Dehydration caused by these factors can make digestion unpredictable. In most cases, it initially causes constipation, followed by diarrhea when the stool finally passes through. This can feel like you are pooping more than usual when your period starts.

Birth Control Can Affect Your Bowel Habits

Hormonal birth control, such as oral pills, patches, and IUDs, reduces prostaglandins and lightens cramps, thus reducing period pain and poops. However, in some women, birth control may cause nausea, more frequent stools, and other digestive changes.

Research suggests that OC pills may also trigger inflammation in the gut, causing pain, frequent period poops, and other digestive symptoms.

PMS or PMDD May Affect Digestion

PMS (Premenstrual Syndrome) and PMDD (Premenstrual Dysphoric Disorder) are associated with significant hormone shifts. These hormonal changes cause mood swings, anxiety, increased cramping, and higher production of prostaglandins.

These changes associated with PMS and PMDD can increase period poops or create more digestive discomfort during your period. These conditions can also be the reasons why does it hurt so bad to poop on my period.

Does Pooping Help Period Cramps

Many women ask, “Does pooping help period cramps?”. The answer is yes; pooping may help relieve period cramps because it reduces pressure in the pelvic area and eases bloating. When your bowels empty, the surrounding muscles and nerves relax. This can help reduce the intensity of menstrual cramps.

However, even though pooping can help reduce period cramps, it is still essential to take steps to avoid frequent loose stools to prevent discomfort, inconvenience, and dehydration.

How to Reduce Excess Pooping During Your Period

If you are frustrated with why are period poops so bad, try these easy, practical tips to reduce excess bowel movement during your period:

Reduce Foods That Trigger Your Gut

Try to limit foods and drinks that irritate the digestive system, such as coffee, chocolate, sugary snacks, fried foods, spicy foods, and dairy, especially if you’re sensitive to them. These items can speed up bowel movements or make your stomach more reactive during your period.

Eat Gut-Friendly Foods

Consume foods that are simple, anti-inflammatory, and easy to digest. Some examples include bananas, rice, yogurt with probiotics, and soothing herbal teas like peppermint or ginger. These foods can calm your digestive system and reduce discomfort.

Stay Hydrated

Make sure you drink plenty of fluids, such as water, coconut water, herbal teas, and electrolytes, if you are experiencing diarrhea. Staying hydrated helps keep your stool soft, but not too loose. It can also regulate your bowel movements and ease digestive discomfort.

Use Heat Therapy

Applying a heating pad to your lower abdomen can make a noticeable difference. Heat helps relax the uterine muscles, reduces prostaglandin activity, calms cramping, and even supports better digestion. This simple tool can ease both period discomfort and digestive spasms.

Manage Stress

Stress has a significant negative impact on digestion. Hence, it is advisable to practice calming methods, such as deep breathing, yoga, or meditation, to support your emotional wellness. These activities can soothe both your mind and your digestive system, making period-related gut issues easier to manage.

Keep a Symptom Journal

Tracking your symptoms each month can help you understand your unique patterns. You can note what you ate, how your stomach felt, your stress levels, and bowel movements on each day of your cycle. Over time, this record will help you anticipate changes and manage your period more confidently.

When to See a Doctor

Pooping more during your period is usually normal. However, you should talk to a doctor if you experience:

• Severe diarrhea every cycle
• Blood in your stool
• Extreme stomach pain
• Sudden changes in bowel habits
• Unexplained weight loss
• Symptoms that interfere with daily life
• Signs of IBS, Crohn’s, or ulcerative colitis

Conclusion

If you’ve been wondering, “Why do I poop so much on my period?”, the answer is simple: hormones. Prostaglandins and fluctuating estrogen and progesterone levels can affect your digestion, making your bowels more active.

Frequent period poops can be annoying, uncomfortable, and sometimes embarrassing. However, simple lifestyle adjustments, better hydration, eating gentle foods, and stress management can help you address why are period poops so bad and make them much more manageable.
