Constipation and Gut Health: Causes, Why It’s More Common in Women, Fibre, Diet & Lifestyle Tips

Constipation is a common digestive concern, but it does not simply mean “not having a bowel movement every day.”

Some people naturally have bowel movements more often than others. What matters more is whether stools are difficult to pass, unusually hard, infrequent, or leave you with a feeling of incomplete emptying.

Constipation can be influenced by many different factors, including diet, hydration, physical activity, stress, medications, medical conditions, hormonal changes, and everyday bowel habits.

It is also particularly common among women, which raises an important question: why are women more likely to experience constipation?

In this article, we’ll explain what constipation is, how it relates to gut health, why it may be more common in women, and how fibre, probiotics, hydration, diet, exercise, and lifestyle habits can support healthy bowel function.

What Is Constipation?

Constipation is generally described as difficulty passing stool or having bowel movements that feel incomplete, infrequent, or uncomfortable.

It may involve:

• Hard or lumpy stools
• Straining during bowel movements
• Feeling that the bowel has not completely emptied
• A sensation that stool is difficult to pass
• Fewer bowel movements than usual

Because bowel habits vary from person to person, frequency alone does not determine whether someone is constipated.

For example, someone who does not have a bowel movement every day may still have normal bowel function if stools are comfortable to pass and there is no significant discomfort.

On the other hand, someone who has a bowel movement every day but consistently passes hard stools with straining or incomplete emptying may still be experiencing constipation.

How Is Stool Formed?

After food is digested and nutrients are absorbed in the stomach and small intestine, the remaining material enters the large intestine.

The colon absorbs water from this material as it moves through the digestive tract. Over time, it gradually becomes more solid and forms stool.

When stool remains in the colon for too long, more water may be absorbed, causing it to become harder and more difficult to pass.

This is one reason why slow bowel movement can contribute to dry, hard stools and straining.

What Is the Connection Between Constipation and Gut Health?

The digestive tract contains trillions of microorganisms, collectively known as the gut microbiota or gut microbiome.

These microorganisms interact with the foods we eat and play important roles in digestion, metabolism, and normal intestinal function.

Gut health is not simply about increasing one type of “good bacteria.”

A healthy intestinal ecosystem contains many different types of microorganisms, and their balance can be influenced by diet, medications, lifestyle, age, and other factors.

For this reason, supporting gut health usually involves looking at the overall diet rather than relying on one food, probiotic strain, or supplement.

Why Dietary Fibre Matters for Gut Health

Dietary fibre is one of the most important parts of a gut-friendly diet.

Fibre is found in plant foods and is not fully digested by human digestive enzymes. Instead, different types of fibre pass through the digestive system and may contribute to stool bulk or be used by gut bacteria.

Good dietary sources include:

• Vegetables
• Fruit
• Legumes
• Whole grains
• Nuts and seeds
• Mushrooms
• Sea vegetables

Eating a variety of plant foods can provide different types of fibre and support a more diverse diet overall.

Insoluble Fibre

Insoluble fibre does not dissolve in water. It can absorb water and add bulk to stool, helping move material through the digestive tract.

It is commonly found in foods such as whole grains, vegetables, legumes, and some nuts and seeds.

Soluble Fibre

Soluble fibre dissolves or forms a gel-like texture in water. Some forms of soluble fibre can also be fermented by gut bacteria.

Foods containing soluble fibre include oats, barley, fruit, legumes, and certain vegetables.

Rather than focusing too heavily on one type, it is generally more practical to obtain fibre from a broad range of plant foods.

Probiotics and Prebiotics: What’s the Difference?

The terms probiotics and prebiotics are often used when discussing gut health, but they mean different things.

What Are Probiotics?

Probiotics are live microorganisms that may provide health benefits when consumed in appropriate amounts.

Certain strains of Lactobacillus and Bifidobacterium are commonly used in fermented foods and dietary supplements.

However, different probiotic strains may have different properties, so not all probiotic products should be considered interchangeable.

What Are Prebiotics?

Prebiotics are substances that are selectively used by beneficial microorganisms in the gut.

Certain types of fibre and oligosaccharides can act as prebiotics and provide a food source for intestinal bacteria.

This is why gut health is often better approached through a combination of fibre-rich foods, fermented foods, and a varied overall diet rather than focusing only on probiotic supplements.

There Are Different Types of Constipation

Constipation does not always occur for the same reason.

It may be related to slow movement through the colon, difficulty with bowel evacuation, medications, medical conditions, or lifestyle factors.

Slow Bowel Movement

In some people, stool moves slowly through the colon. This gives the colon more time to absorb water, which can make stools hard and difficult to pass.

Low physical activity, reduced food intake, dehydration, aging, and other factors may contribute.

Difficulty With Evacuation

Some people feel that stool has reached the rectum but is still difficult to pass.

This may involve repeated straining, incomplete emptying, or difficulty coordinating the muscles used during bowel movements.

Constipation Caused by Medication or Medical Conditions

Constipation can sometimes be related to medical conditions such as thyroid disorders, diabetes, neurological conditions, or diseases affecting the digestive tract.

Certain medications can also contribute to constipation.

For this reason, persistent constipation should not automatically be assumed to be caused by a lack of fibre.

In the next section, we’ll look at why constipation is particularly common in women, including the roles of hormones, pregnancy, dieting, stress, and daily bowel habits.

Why Is Constipation More Common in Women?

Constipation can affect anyone, but studies consistently show that it is more common in women than in men.

This difference is thought to result from a combination of hormonal changes, pregnancy, pelvic floor function, lifestyle factors, and dietary habits rather than a single cause.

Understanding these contributing factors may help explain why constipation often becomes a recurring concern for many women throughout different stages of life.

Hormonal Changes

Female sex hormones naturally fluctuate throughout the menstrual cycle, pregnancy, and menopause.

During certain phases of the menstrual cycle, some women notice changes in bowel habits, including constipation or slower bowel movements.

Hormonal changes during pregnancy may also slow intestinal movement, making constipation more likely.

Pregnancy

Constipation is one of the most common digestive complaints during pregnancy.

Hormonal changes, reduced physical activity, pressure from the growing uterus, and iron supplements prescribed during pregnancy may all contribute.

Pregnant women experiencing persistent constipation should seek advice from their healthcare provider before using laxatives or dietary supplements.

Dieting and Low Food Intake

Restrictive diets and skipping meals may reduce the total amount of food and fibre entering the digestive tract.

When less material moves through the intestines, bowel movements may become less frequent.

People trying to lose weight should aim for a nutritionally balanced eating pattern rather than severely restricting food intake.

Stress and Daily Routine

Emotional stress, irregular schedules, travel, shift work, and changes in routine may all influence normal bowel habits.

Some people also delay going to the toilet because they are busy or away from home. Repeatedly ignoring the urge to have a bowel movement may contribute to constipation over time.

How Lifestyle Affects Bowel Regularity

Healthy bowel habits are influenced by everyday lifestyle choices as well as diet.

Small daily habits can make a meaningful difference over time.

Stay Hydrated

Water helps keep stool softer and easier to pass.

Individual fluid requirements vary depending on age, climate, activity level, and health status, but drinking adequate fluids throughout the day is generally recommended.

Be Physically Active

Regular physical activity supports many aspects of health, including normal digestive function.

Even moderate daily activities such as walking may help support regular bowel movements as part of a healthy lifestyle.

Respond to the Natural Urge

When you feel the urge to have a bowel movement, try not to delay it unnecessarily.

Developing a consistent bathroom routine may help support regular bowel habits for some people.

Eat Meals Regularly

Regular meal patterns help stimulate normal digestive activity.

Skipping meals or eating irregularly may reduce this natural stimulation in some individuals.

Foods That May Help Support Regular Bowel Function

No single food prevents constipation, but a diet rich in plant foods provides dietary fibre and other nutrients that contribute to overall digestive health.

Foods commonly recommended as part of a balanced, fibre-rich diet include:

• Kiwifruit
• Prunes and dried plums
• Pears
• Apples
• Berries
• Beans and lentils
• Oats
• Wholegrain bread and cereals
• Leafy green vegetables

Increasing fibre intake gradually while also drinking enough water may help minimise digestive discomfort that sometimes occurs with sudden increases in fibre.

Can Probiotic Supplements Help?

Probiotics continue to be an active area of scientific research.

Some clinical studies suggest that certain probiotic strains may help support normal bowel function in some individuals. However, results vary depending on the specific strain, dose, and the individual taking the supplement.

Not all probiotic products are the same, and benefits observed for one strain cannot automatically be applied to another.

Probiotic supplements should be viewed as one possible part of an overall healthy lifestyle rather than a standalone solution for constipation.

Next, we'll explore practical daily strategies for maintaining gut health, answer common questions about constipation, and summarise key takeaways.

Simple Daily Habits That May Support Gut Health

Healthy digestion is influenced by much more than a single food or supplement. Consistent lifestyle habits often play an equally important role in supporting normal bowel function.

While occasional constipation is common, developing healthy daily routines may help support long-term digestive health.

Eat Enough Dietary Fibre

Most adults do not consume enough dietary fibre each day.

Including vegetables, fruit, legumes, whole grains, nuts, and seeds in your meals can naturally increase fibre intake while also providing vitamins, minerals, and other beneficial plant compounds.

Rather than relying on one "high-fibre" food, aim for a wide variety of plant-based foods throughout the week.

Drink Enough Water

Fibre works best when combined with adequate fluid intake.

Drinking enough water throughout the day helps maintain normal digestive function and supports healthy stool consistency.

Keep Moving

Regular physical activity supports overall health and may also help maintain normal bowel function.

Activities such as walking, cycling, swimming, or other forms of regular exercise can easily become part of a healthy lifestyle.

Develop Regular Toilet Habits

Listening to your body's natural urge to have a bowel movement is important.

Frequently delaying bowel movements may contribute to harder stools over time.

Many people find it helpful to establish a consistent daily routine, particularly after breakfast when bowel activity naturally increases.

Manage Stress

The digestive system and the nervous system communicate closely through what is often called the gut-brain axis.

Ongoing stress may influence digestive comfort and bowel habits in some individuals.

Getting enough sleep, exercising regularly, and making time to relax can all contribute to overall wellbeing.

Can Fruit Help Support Regular Bowel Movements?

Fruit provides dietary fibre, water, vitamins, minerals, and naturally occurring plant compounds that contribute to a balanced diet.

Some fruits also contain both soluble and insoluble fibre, making them useful components of a fibre-rich eating pattern.

Fruits commonly included in diets that support digestive health include:

• Kiwifruit
• Pears
• Apples
• Berries
• Prunes
• Oranges

Rather than focusing on one particular fruit, eating a variety of fruits throughout the week provides a wider range of nutrients and fibre.

Can Tea Be Part of a Healthy Lifestyle?

Unsweetened tea can be an enjoyable way to increase daily fluid intake.

Herbal teas and fruit infusions also offer a variety of flavours, making it easier for some people to stay hydrated throughout the day.

Tea should be viewed as part of an overall balanced lifestyle rather than as a treatment for constipation.

Frequently Asked Questions

How often should you have a bowel movement?

Normal bowel habits vary considerably between individuals. Some healthy people have bowel movements several times a day, while others may have them every second or third day.

The most important consideration is whether bowel movements are comfortable and consistent for you.

Is constipation always caused by a lack of fibre?

No. Although insufficient fibre intake is one possible cause, constipation may also be related to dehydration, medications, hormonal changes, reduced physical activity, medical conditions, stress, or pelvic floor dysfunction.

Are probiotics necessary for everyone?

Not necessarily. Many people can support their gut health by eating a varied, fibre-rich diet without taking probiotic supplements.

Some probiotic strains have been studied for digestive health, but their effects may differ depending on the strain and the individual.

Can drinking more water help with constipation?

Staying well hydrated is an important part of healthy digestion. Drinking enough fluids, together with eating adequate dietary fibre, may help support normal bowel function.

Water alone is unlikely to resolve chronic constipation, but adequate hydration remains an essential part of a healthy lifestyle.

Should I take laxatives for constipation?

Occasional use of laxatives may be appropriate for some people under the guidance of a healthcare professional.

However, persistent or recurrent constipation should be properly assessed rather than relying on long-term self-treatment.

When should I see a doctor?

Seek medical advice if constipation is persistent, becomes significantly worse, or is accompanied by symptoms such as:

• Blood in the stool
• Severe abdominal pain
• Persistent vomiting
• Unexplained weight loss
• Iron deficiency anaemia
• A sudden change in bowel habits

These symptoms require medical assessment and should not be attributed to diet alone.

Conclusion: Healthy Digestion Starts with Everyday Habits

Constipation is a common condition with many possible causes. While dietary fibre is an important part of digestive health, hydration, physical activity, stress management, regular eating habits, and overall nutrition also play essential roles.

Women may experience constipation more frequently due to hormonal changes, pregnancy, and other physiological factors, but healthy lifestyle habits can help support normal bowel function throughout life.

A varied diet rich in vegetables, fruits, legumes, whole grains, and other plant foods provides dietary fibre and nutrients that contribute to a healthy digestive system.

Probiotic supplements may also be considered by some individuals as part of their overall wellness routine, but they should complement—not replace—a balanced diet and healthy lifestyle.

If constipation persists or is accompanied by concerning symptoms, seeking professional medical advice is always recommended.
