Constipation During Perimenopause: Causes and What Helps

Constipation can be a symptom of perimenopause. Falling and fluctuating hormones slow the gut for many women, and stress, sleep, diet and activity add to the effect. In a Women’s Health Concern survey, 54% of participants reported constipation, so it is far from rare. Most cases respond to steady changes in fibre, fluids, movement and routine. Some signs need a GP.

TL;DR

  • Constipation is a recognised perimenopause symptom. Some women also get looser stools, and the two can alternate.
  • Hormones are one factor. Fibre, fluids, activity, stress, sleep and medicines also play a part.
  • Raise fibre gradually, drink regularly, eat at steady times and respond to the urge to go.
  • Blood in the stool, black stools, unexplained weight loss, severe pain or a lasting change in bowel habit need a GP appointment.
  • Wholefoods such as seeds, nut butters and wholegrain flakes can be part of an everyday eating pattern.

What counts as constipation

The NHS describes constipation as a change in how you poo. That can mean going less often or finding it hard to go. Likely signs include:

  • fewer than three poos in the last week
  • unusually large or small stools that are dry, hard or lumpy
  • straining or pain
  • a feeling that the bowel has not fully emptied

Mayo Clinic defines chronic constipation as two or more of the listed symptoms lasting three months or longer. Knowing which pattern you have helps when you speak to a GP or pharmacist.

Is constipation a symptom of perimenopause?

Yes, it can be. The Women’s Health Concern factsheet reports that 94% of survey participants had digestive issues during menopause. Of these, 38% had digestive symptoms for the first time at the onset of perimenopause. Bloating affected 77%, constipation 54%, stomach pain 50% and acid reflux 49%.

Survey percentages for digestive symptoms during menopause

That does not mean every change in bowel habit is hormonal. Perimenopause tends to arrive in the same years as busy work, caring duties, poorer sleep and changes to routine. The honest picture is a mix of causes, covered next. Our guide to perimenopause bowel changes covers the wider pattern.

Why perimenopause can slow the gut

The gut has receptors for oestrogen and progesterone, so shifts in both can change how quickly food travels through. A Northwestern Health Sciences University article explains that progesterone slows digestion and can lead to constipation, gas and bloating. Oestrogen tends to speed digestion up. When both fall, food moves more slowly through the gut.

Verywell Health adds that declining progesterone can leave stool in the colon for longer. The stool then dries into small, hard pieces. It also lists pelvic floor changes, pain that limits movement, diet, dehydration, medicines and low activity as contributors.

Stress and cortisol

Hormones are not the whole story. The Seattle Midlife Women’s Health Study found that key reproductive hormones did not play a significant role in the severity of constipation or diarrhoea during the menopause transition. Stress perception, tension, anxiety and cortisol were linked with severity. Tension and cortisol stayed significant predictors of constipation severity.

So the practical lesson is to treat the whole picture. Sleep, stress and daily routine matter alongside food. The Canadian Digestive Health Foundation also notes that gut symptoms in perimenopause usually have more than one cause. Poor sleep and stress are linked with worse symptoms. Pelvic floor changes with age and hormones may make it harder to empty the bowel fully.

Everyday causes that still apply

The NHS lists the common causes of constipation at any age:

  • not enough fibre
  • not enough fluids
  • being less active
  • often ignoring the urge to go
  • a change of diet or routine
  • side effects of medicines
  • stress, anxiety or depression

If any of these changed in your forties, they may matter as much as hormones.

Can perimenopause cause diarrhoea too?

Yes. Women’s Health Concern states that some women have constipation and others have diarrhoea, and the two can alternate over time. Constipation often reflects slower gut transit. Diarrhoea can come from faster motility or sensitivity to certain foods.

The Canadian Digestive Health Foundation says that some women have looser stools instead of constipation, and some swing between both. Dietitian Christel Lyell explains that falling progesterone can speed transit. Fluctuating oestrogen may change how bile is handled, which can make stools looser and urgency more noticeable. She adds that most bowel changes in perimenopause are functional rather than serious.

If you swing between the two, do not assume a single fix will work. Keep a simple note of what you eat, when you go and how you feel. Bring the note to your GP if the pattern continues.

What helps: food, fluids and habits

Raise fibre gradually

NHS advice is to eat enough fibre. Yale Medicine recommends about 25 to 30 grams of fibre a day for most adults. It notes that fibre supplements may help some women but should be discussed with a clinician first.

The pace matters. Increasing fibre quickly can worsen bloating and discomfort, so add one change at a time over a few weeks. The Canadian Digestive Health Foundation suggests soluble fibre sources such as chia seeds, oats and cooked vegetables, and raising intake gradually.

Eat regularly and start the day well

The same foundation recommends three to four evenly spaced meals and avoiding long fasts. Its suggested start to the day is hydration, light movement and a fibre-rich breakfast within one to two hours of waking. Women’s Health Concern also advises eating regularly and mindfully. It suggests cutting back on trigger foods such as fatty foods, caffeine, alcohol and spicy meals.

Drink steadily through the day

Women’s Health Concern advises at least eight glasses of water a day. Our guide to drinks for menopause covers what to sip, limit and skip. Warm drinks count towards fluids, and our notes on low-risk teas for perimenopause show some options.

Move and make time for the toilet

The NHS names low activity and ignoring the urge as causes, so the reverse helps. Walk daily, and go when you feel the urge rather than waiting. Many women find that a regular slot after a meal makes a routine easier to keep. Gentle exercise such as walking or swimming is also commonly suggested for digestive health in menopause.

Manage stress and sleep

Given the Seattle findings on tension and cortisol, stress management is not an optional extra. Short walks, breathing exercises, a fixed bedtime and time away from screens all support the gut indirectly. Our look at fluid retention in menopause covers another symptom that often travels with bloating.

A day of eating for a steadier gut

This is a general example of an eating pattern, not a prescription. Adjust it to your own tolerances and any medical advice you have received.

Time Idea Why it fits
On waking A glass of water, a short walk Hydration and light movement to begin the day
Breakfast Porridge made with wholegrain flakes, a spoonful of seeds, fruit A fibre-rich start within one to two hours of waking
Mid-morning Water, herbal tea Steady fluids
Lunch Vegetables, pulses or wholegrains with a protein Regular meals, varied fibre
Afternoon Toast with nut butter, or a smoothie A planned snack avoids long gaps
Evening Cooked vegetables with a protein and a grain Cooked vegetables are a gentler form of fibre

Protein deserves attention too, because it supports appetite and muscle through midlife. Our guide on why protein matters for menopause explains how to fit it in. For blended options, see our menopause smoothie recipes.

Prunes and other familiar foods

Prunes are a familiar breakfast and snack food. A clinician-reviewed page on prunes and postmenopausal bone density refers to a daily portion of four to six. Stir a few chopped prunes into porridge, then watch how your gut responds. If you take medicines, or have a condition affecting digestion, ask your pharmacist or GP before relying on any food or supplement as a remedy.

What to go slowly with

A doctor quoted by Mahila Women’s Clinic notes that digestive symptoms have many possible causes. These include diet, stress, sleep, medicines, irritable bowel syndrome, coeliac disease and food intolerance. She advises that increasing fibre rapidly can worsen bloating. That is another reason to change one thing at a time, and to individualise advice when symptoms persist.

Magnesium, probiotics and fibre supplements are often suggested online. Women’s Health Concern advises monitoring the effects of probiotics for at least four weeks. Check any supplement with a pharmacist or GP first, particularly if you take regular medicines.

Our perspective

We see constipation in perimenopause as a daily-routine problem before it is a product problem. Steady meals, enough water, movement and unhurried mornings do most of the work.

Our approach is wholefood and simple. Ancient grain flakes for porridge, seeds to stir in, nut butters on wholegrain toast and plant or dairy proteins in a smoothie are everyday ingredients with clear labels. We choose each for what it is, and we list ingredients plainly so you can see exactly what you are eating.

A gradual build works best. Start with one breakfast, keep it for two weeks, then add the next change. Our range is built around this kind of food: minimal processing, short ingredient lists, and foods that fit regular mealtimes.

When to see a GP

Most perimenopause bowel changes are functional, but some signs need checking promptly. Yale Medicine lists the following as warranting prompt medical attention:

  • blood in the stool
  • black or tarry stools
  • a change in bowel habit
  • unexplained weight loss
  • ongoing or worsening abdominal pain
  • difficulty swallowing, or new reflux symptoms several times a week

The Canadian Digestive Health Foundation adds a bowel-habit change lasting more than a few weeks, ongoing vomiting, very heavy periods, ongoing tiredness, and a family history of colorectal cancer or inflammatory bowel disease. Christel Lyell adds night-time diarrhoea, fever, or new symptoms starting suddenly after 50. If you have heavy periods or tiredness, our pages on low iron in perimenopause and iron supplements explain the testing route.

If constipation or diarrhoea continues despite more fibre, adequate water and activity, gastroenterologist Dr Sara Yacyshyn says that is a good time to speak to a specialist. Treatments may include over-the-counter or prescription medicines, and a doctor may suggest an endoscopy.

Over 45, the Canadian foundation advises discussing the benefits and risks of early colorectal cancer screening, especially with a family history or new bowel-habit changes. In the UK, a GP can explain which screening applies to you. Discuss digestive changes in your forties with a GP before major diet or supplement changes.

FAQ

Is constipation a symptom of perimenopause?

It can be. In the Women’s Health Concern survey, 54% of participants reported constipation. Hormone shifts, stress, sleep, diet and activity can all contribute. If it lasts or comes with warning signs, see a GP.

Is diarrhoea a symptom of perimenopause?

It can be. Some women have looser stools, and some alternate between diarrhoea and constipation. Faster gut transit, food sensitivity and changing hormones are possible reasons. Severe, lasting or bloody diarrhoea needs medical advice.

How much fibre should I aim for?

Yale Medicine suggests about 25 to 30 grams a day for most adults. Build up gradually and drink regularly as you do. Rapid increases can worsen bloating.

Should I take a fibre supplement or probiotic?

Some women find them helpful, but Yale Medicine advises discussing fibre supplements with a clinician. Women’s Health Concern suggests monitoring a probiotic for at least four weeks. Ask a pharmacist or GP if you take other medicines.
