Constipation Before or During Periods: Why Does It Happen?

If you find yourself feeling constipated before or during your period, your menstrual cycle may be contributing to the change in your digestion. Hormonal fluctuations throughout the cycle can affect bowel movements, and progesterone may slow the movement of food through the digestive system for some people.

Period-related constipation can mean having fewer bowel movements, passing hard or dry stools, straining or feeling like you have not completely emptied your bowels.

What Is Period Constipation?

Period constipation refers to constipation that appears or becomes worse around the time of your menstrual cycle.

Constipation itself can involve fewer than three bowel movements a week, hard or lumpy stools, difficulty passing stool or a feeling that some stool remains after a bowel movement.

Your normal bowel pattern can be different from someone else's, so a change from what is normal for you can be just as useful to notice.

Why Do You Get Constipation Before Your Period?

Hormonal changes are one possible reason for constipation before your period.

Progesterone rises during the part of the menstrual cycle after ovulation. For some people, higher progesterone can slow bowel movements and contribute to constipation.

This means you may notice constipation in the days before your period even if your digestion is usually regular during the rest of the month.

Can Hormones Cause Constipation During Your Period?

Yes, menstrual-cycle hormones can influence bowel habits, but constipation is not the only digestive change that can happen around your period.

Prostaglandins released around menstruation can affect the intestines as well as the uterus. In some people, this leads to more frequent bowel movements or diarrhea rather than constipation.

So it is possible to be constipated before your period and then experience looser or more frequent stools once your period starts.

What Are the Symptoms of Period Constipation?

Period constipation can feel similar to constipation at any other time.

You may notice:

• Fewer bowel movements than usual

• Hard or dry stools

• Straining when passing stool

• Pain or discomfort while passing stool

• A feeling that you have not completely emptied your bowels

• Bloating or abdominal discomfort

These are recognised symptoms of constipation.

Why Do Period Constipation and Bloating Happen Together?

Constipation can make you feel bloated or uncomfortable because stool is moving more slowly through the digestive system.

At the same time, hormonal changes around your period can cause other digestive and fluid-related symptoms. This can make your stomach feel particularly uncomfortable during the days surrounding menstruation.

If bloating is severe, persistent or accompanied by significant pain or other unusual symptoms, it is worth discussing with a healthcare professional.

Can Period Cramps Make Constipation Feel Worse?

Period cramps and constipation can happen at the same time, which can make abdominal discomfort feel more noticeable.

The uterus contracts during menstruation because of prostaglandins, causing the cramping sensation associated with periods. Prostaglandins can also affect bowel activity.

If you are experiencing severe pelvic or abdominal pain along with constipation, do not automatically assume it is simply period constipation.

How Can You Relieve Constipation Before Your Period?

Simple habits can often help mild constipation.

1. Eat More Fiber

Fiber can help make stools softer and easier to pass. Good sources include whole grains, oats, lentils, chickpeas, beans, fruits, vegetables, nuts and seeds.

Increase fiber gradually rather than suddenly adding a very large amount to your diet.

2. Drink Enough Fluids

Fluids help fiber work properly and can make stools easier to pass. Drinking enough water throughout the day is therefore an important part of managing constipation.

If you increase your fiber intake, make sure you are also getting enough fluids.

3. Stay Physically Active

Regular physical activity may help relieve constipation. Even simple movement can be useful if you have been sitting for long periods.

Walking, gentle stretching or other activities you are comfortable with can be incorporated into your routine.

4. Don't Ignore the Urge to Go

Ignoring the urge to have a bowel movement can contribute to constipation.

Give yourself enough time in the bathroom and try not to rush. NIDDK also notes that trying to have a bowel movement after breakfast may help some people establish a more regular routine.

5. Increase Fiber Gradually

Adding a lot of fiber suddenly can sometimes cause additional gas or bloating. Increase fiber gradually so your digestive system has time to adjust.

What Foods Can Help With Period Constipation?

There is no special “period constipation diet,” but fiber-rich foods can help support regular bowel movements.

Some options include:

• Oats and whole grains

• Dal and lentils

• Chickpeas and beans

• Apples and pears

• Berries

• Vegetables

• Nuts and seeds

• Whole-grain bread or roti

Drinking enough fluids alongside fiber is important because fluids help soften stools and make them easier to pass.

Should You Take a Laxative for Period Constipation?

Not necessarily. Mild constipation can often improve with changes to food, fluids, physical activity and bathroom habits.

If those changes do not help, a healthcare professional may recommend a short-term laxative or another treatment depending on the cause of your constipation.

Avoid regularly taking laxatives without professional advice, especially if constipation keeps coming back.

Can Period Constipation Be a Sign of Something Else?

Sometimes. Constipation has many possible causes, including low fiber intake, dehydration, low physical activity, changes in routine, certain medications and some medical conditions.

If constipation appears only around your period and resolves afterward, your menstrual cycle may be contributing to the pattern. But persistent constipation should not automatically be blamed on hormones.

Is Constipation Before Your Period Normal?

Mild changes in bowel habits around your menstrual cycle can happen. Hormonal changes can affect the digestive system, and some people notice constipation before menstruation.

However, constipation that is persistent, severe or significantly different from your normal bowel habits deserves attention.

Why Do Some Women Get Diarrhea Instead of Constipation During Their Period?

The menstrual cycle can affect the bowel in different ways.

Prostaglandins released around menstruation can increase bowel activity, which may lead to more frequent bowel movements or diarrhea. Progesterone, on the other hand, can promote constipation in some people during other parts of the cycle.

That is why one person may experience constipation before their period while another notices looser stools during menstruation.

When Should You See a Doctor About Period Constipation?

Talk to a healthcare professional if your constipation does not improve with self-care, keeps returning or is affecting your everyday life.

Seek medical attention promptly if constipation occurs with blood in your stool, rectal bleeding, constant abdominal pain, vomiting, fever, inability to pass gas or unexplained weight loss.

You should also speak with a doctor if you develop a significant change in your usual bowel habits that does not settle after your period.
