Why Am I Always Constipated? Common Root Causes of Constipation in Women

A Functional Medicine Guide

Constipation is one of those symptoms many women live with for years without realising how much it is affecting the rest of the body.

And I’m not only talking about not going to the toilet for several days. Several patients also tell me:

• “I go every day, but I still feel blocked.”

• “I never feel fully emptied.”

• “I feel heavy, bloated and uncomfortable all the time.”

• “My digestion feels slow.”

Healthy bowel movements are not only about frequency, they are also about regularity, ease, complete evacuation, and transit time.

Your body is supposed to eliminate waste daily. When elimination becomes slow, the effects usually start appearing far beyond digestion alone.

Is it normal not to poop every day?

In my clinical opinion: no.

I hear often women saying that they are pooping every 2–3 days and they find it “normal”. Sorry, it is not. A healthy digestive system should ideally produce 1 to 3 soft and complete bowel movements daily. This means:

• stools pass without excessive straining

• you feel properly emptied afterwards

• bowel movements happen regularly

• digestion feels relatively comfortable

From a Functional Medicine perspective, slower bowel transit means waste stays longer inside the intestine than it should. This matters because the gut is not only absorbing nutrients, it is also eliminating hormones, toxins, metabolic waste, and inflammatory compounds.

When transit becomes slow, the body may start reabsorbing some of these compounds back into circulation. This is one reason constipation is often associated with:

• bloating

• hormonal symptoms

• skin flare-ups

• brain fog

• fatigue

• feeling inflamed

• PMS worsening

Understanding what can be the Root-Cause of Constipation

Constipation is rarely only about “not eating enough fibre” - this is one of the biggest misconceptions I see online.

The bowel is influenced by many systems working together: the nervous system, hormones, gut bacteria, hydration, movement, digestion and even emotional stress.

This is why two women can both feel constipated for completely different reasons and understanding the root-cause matters because the solution is not the same for everyone.

1. Slowed Gut Motility

One of the most common root-causes I see is reduced gut motility. Motility is basically the movement of the intestine, the muscular contractions that push stool forward.

When motility slows down, transit time becomes longer. Stool stays in the colon for too long, more water gets reabsorbed, and bowel movements become harder, drier and more difficult to pass. This can happen from:

• chronic stress

• lack of movement

• magnesium deficiency

• hormonal changes

• under-eating

• restrictive diets

• nervous system dysregulation

Many of my patients, and probably you, live in a constant “freeze” physiology without realising it, by sitting all day, being mentally overloaded, barely breathing deeply, disconnected from their body’s natural rhythm. The bowel feels this.

2. Gut Dysbiosis and Unhealthy Gut Flora

Your gut bacteria help regulate bowel movements much more than most women realise.

Certain bacteria produce compounds that stimulate motility and help keep stools soft and regular.

But when the microbiome becomes imbalanced, what we call dysbiosis, constipation often appears together with:

• bloating

• excessive gas

• brain fog

• cravings

• fatigue

• skin flare-ups

One pattern I see very often is methane-dominant SIBO. Methane-producing bacteria actually slow the intestine down. This is why some women feel:

• heavy

• distended

• extremely bloated

• constipated despite eating fibre

This is also why simply adding more fibre sometimes makes women feel worse instead of better, because the problem is not always lack of fibre, sometimes it is the environment fermenting the fibre improperly.

3. Chronic Stress and Nervous System Dysregulation

The digestive system works best when the body feels safe, but many of us are eating, working and living in a constant stress response.

We are rushing, constantly multitasking, overthinking, and barely sitting down properly to eat. Under these conditions, physiologically, the body deprioritises digestion under stress.

Which leads to: stomach acid decrease, digestive enzymes decrease, blood flow shift away from the gut, and slow down of motility. This is why stress and constipation are deeply connected.

In my practice, some women notice significant improvements in bowel regularity simply from:

• slowing meals down

• sleeping better

• walking more

• reducing nervous system overload

• creating more routine around meals and bowel habits

4. Hormonal Changes

Women are naturally more constipated than men.

Hormones influence bowel motility constantly throughout the cycle. Many of us notice constipation worsening:

• before their period

• during pregnancy

• during stressful periods

• in perimenopause

Progesterone especially tends to slow intestinal movement, this is why bowel habits often change alongside:

• bloating

• PMS

• fluid retention

• hormonal acne

• feeling heavier or puffier

When constipation becomes chronic, hormone clearance may also become less efficient, especially estrogen elimination through the bowel. This is one reason constipation and hormonal symptoms often coexist.

5. Food, Fibre and Digestive Habits

Yes, nutrition matters, but not only in the simplistic “eat more fibre” way.

Constipation is often linked to:

• low fibre diversity

• ultra-processed foods

• dehydration

• poor digestion

• skipping meals

• under-eating

• eating too quickly

• lack of healthy fats

I see this often: many women are simply not eating enough fibre, healthy fats or drinking enough water consistently. At the same time, habits like skipping meals, eating on the go, rushing through meals or sitting for long periods can make it even harder for the bowel to establish a healthy rhythm.

The truth is that the bowel responds to much more than a single supplement. It responds to:

• regular meals

• adequate hydration

• daily movement

• enough food volume

• fibre diversity

• a regulated nervous system

This is why lasting improvements usually come from supporting these foundations consistently

6. Medications and Supplements

Certain medications slow bowel movements significantly. Common examples include:

• iron supplements

• antidepressants

• antacids

• opiates

• calcium channel blockers

Even overusing laxatives long-term can eventually reduce the bowel’s ability to function naturally on its own. This is why understanding the full picture matters before trying to “fix” constipation with another supplement.

How I usually start supporting Constipation Naturally

One thing I’ve learned working with women is that the gut responds much better to consistency than to extremes.

Many of my patients already arrive overwhelmed: drinking random teas, trying detoxes, taking laxatives, adding huge amounts of fibre overnight… and often ending up even more bloated.

So instead of trying to “force” the bowel, I usually start by helping the body restore proper rhythm and motility progressively.

Small things repeated daily often make a much bigger difference than you canexpect.

The real goal is helping the bowel recover its own rhythm again, without depending on laxatives.

This usually requires supporting:

• motility

• hydration

• microbiome balance

• nervous system regulation

• magnesium status

• movement

• digestion

consistently enough that the body remembers how to eliminate properly again.

1. Start the morning by stimulating the Gut naturally

One of the simplest ways to help bowel motility is creating more consistency in the morning.

The gut is naturally more active after waking and after eating. This is why breakfast timing matters more than you probably realise.

I usually encourage my patients not to skip breakfast completely if constipation is chronic.

A breakfast rich in fibre, hydration and healthy fats can help stimulate bowel movement much more effectively than coffee alone.

Simple examples:

• greek yogurt with chia seeds, flaxseeds, kiwi and oats

• eggs with spinach and avocado with sesame seeds on the top

• porridge with chia seeds, flaxseeds and berries

• overnight oats with chia and hemp seeds

Kiwi is particularly interesting because studies actually show it can help improve bowel frequency naturally. Chia, flaxseeds and psyllium work best when they are consumed consistently and with enough water.

2. Hydration matters more than “Drinking more water”

Many women drink water only later in the day, but bowel motility responds much better when hydration starts early.

One of the simplest things I recommend is: drinking 1–2 large glasses of water within the first 30 minutes after waking up.

Especially if combined with:

• movement

• breakfast

• magnesium

• warm liquids like ginger tea

This often helps activate the gastrocolic reflex, the natural stimulation of bowel movement after eating and drinking. Many of my patients notice a difference from this alone after a few days.

3. Movement is one of the most effective things for Constipation

The intestine is a muscle-based system, it responds to movement. This is why sedentary lifestyles slow motility significantly.

However, you do not need extreme exercise for this. The forms of movement I see helping constipation the most are usually:

• walking

• walking after meals

• pilates

• mobility work

• light jogging

• strength training

• yoga twists and deep breathing

Walking after meals is especially effective because it mechanically stimulates digestion and bowel motility. Even 10–15 minutes makes a difference.

4. Increase fibre slowly

This is where many women unintentionally make constipation worse. They suddenly start eating:

• huge salads

• fibre cereals

• fibre supplements

• raw vegetables all day

Then become more bloated, more uncomfortable, more constipated, because the microbiome needs time to adapt.

I usually prefer building fibre progressively. For example:

Week 1: add chia or flaxseeds at breakfast

Week 2: add cooked vegetables at lunch and dinner

Week 3: introduce legumes 2–3x/week

Week 4: diversify plant intake progressively

Cooked vegetables are often easier to tolerate initially than large amounts of raw salads.

Especially:

• zucchini

• carrots

• spinach

• pumpkin

• asparagus

• green beans

  
  

5. Magnesium Can Make a Huge Difference

One of the most overlooked causes of constipation in women is magnesium deficiency.

Magnesium helps regulate muscle contractions, including the muscles of the intestine, and many women are depleted due to:

• stress

• caffeine

• poor sleep

• hormonal changes

• restrictive eating

• chronic stress physiology

Magnesium citrate is usually the form I use most often for constipation support because it also helps draw water into the bowel gently. Within days, many of my patients notice:

• softer stools

• easier evacuation

• less bloating

• more regularity

What looks like a simple day that supports bowel regularity

This is the kind of structure that often helps support motility naturally:

Breakfast: greek yogurt, chia seeds, kiwi, oats and cinnamon

Lunch: salmon, rice, cooked greens and olive oil

Snack: fruit + handful of almonds or pumpkin seeds

Dinner: lentil soup with vegetables and sourdough toast

After meals: 10–15 minute walk

Hydration: water throughout the day, not only at night

Together with regular meals, enough food and enough nourishment, because under-eating also slows the gut.

How long does it take to improve constipation?

This depends on the root cause.

Some women notice changes within days from improving hydration, magnesium intake, movement or bowel habits. Others need longer, especially when constipation is connected to:

• chronic stress

• SIBO

• dysbiosis

• hormonal changes

• long-term laxative use

• nervous system dysregulation

But usually, when the body starts feeling safer and more supported consistently, bowel movements begin improving progressively too.

When should you seek professional support?

I would strongly recommend seeking support if:

• constipation is chronic

• you rely on laxatives regularly

• you feel bloated all the time

• bowel movements are painful

• you see blood

• you feel incomplete evacuation constantly

• constipation is affecting your quality of life

• you also experience fatigue, hormonal symptoms or digestive discomfort

As you could see before, constipation is often not only a gut issue. It is frequently connected to the nervous system, hormones, inflammation and the overall state of the body.

How I can Help you

If you keep asking yourself "why am I always constipated?", know that the answer is often more complex than simply needing more fibre or water.

Constipation is rarely an isolated symptom. It is often the result of several factors interacting together, including stress, hormones, gut imbalances, reduced motility, inflammation and lifestyle habits. This is why identifying the root-cause is often what finally allows women to experience lasting improvements. This is why in my practice, I look at constipation through a whole-body Functional Medicine approach.

I look at the patterns together: digestion, stress, hormones, lifestyle, bowel habits, nutrition and associated symptoms.

From there, we rebuild bowel function step by step in a structured and sustainable way, by helping the body regulate and eliminate properly again, not only temporarily, but long-term.

This is why, care with me may include:

• an in-depth understanding of your symptoms, health history and lifestyle

• identifying the physiological patterns contributing to your constipation

• functional testing when needed

• nutrition and supplementation adapted to your body’s needs

• guidance to support stress regulation and movement

• regular adjustments as your body starts responding and rebuilding over time

Frequently Asked Questions

Is it normal not to poop every day?

No. While bowel habits vary between people, a healthy digestive system should ideally produce one to three soft and complete bowel movements daily. Going every two or three days may be common, but it often means stool is staying in the intestine longer than optimal, which can contribute to bloating, discomfort and slower elimination of waste products.

Why am I constipated all the time even though I eat healthy?

Constipation is not only caused by low fibre intake. Stress, gut dysbiosis, hormonal changes, low magnesium levels, dehydration, lack of movement, medications and digestive imbalances can all contribute. This is why some women remain constipated despite eating what they consider a healthy diet.

Can stress cause constipation?

Yes. The digestive system works best when the nervous system feels safe and relaxed. Chronic stress can slow gut motility, reduce digestive secretions and alter the gut microbiome, all of which can contribute to constipation. Many women notice their digestion changes significantly during stressful periods.

Can constipation affect hormones?

Yes. One of the ways the body eliminates used hormones, including estrogen, is through the bowel. When bowel movements become infrequent, hormone metabolites can remain in the digestive tract longer than intended. This is one reason constipation is often associated with symptoms such as PMS, bloating, heavy periods and hormonal imbalances.

What is the best natural remedy for constipation?

The most effective approach depends on the root cause. However, improving hydration, increasing fibre gradually, supporting gut motility through movement, correcting magnesium deficiency and addressing stress are often some of the most impactful first steps. Lasting improvements usually come from supporting the body's natural bowel function rather than relying solely on laxatives.

Why am I bloated and constipated at the same time?

Bloating and constipation often occur together because stool and gas remain in the intestine for longer. Common underlying causes include gut dysbiosis, SIBO, slow gut motility, food sensitivities, stress and hormonal changes. Looking at both symptoms together often provides important clues about the root cause.
