Why are women more often affected by irritable bowel syndrome (IBS) than men? What role do the gut-brain axis, hormones and the microbiome play? In this article, I break down the current scientific understanding and explain why IBS is usually driven by several factors at once – and what that means for the everyday lives of the women who live with it.
"Can I eat something spicy today?"
"I should probably find a seat close to the bathroom."
"I hope my stomach stays calm during the meeting."
For many women, thoughts like these are part of everyday life. IBS is far more than a digestive complaint. The condition can affect daily routines, eating habits and social life – often for years at a time. That's exactly why it's worth taking a closer look at the current scientific evidence, and at the options available today for addressing symptoms holistically.
You'll learn why women are more often affected by IBS, which causes are currently being discussed, how IBS is diagnosed, what treatment options exist, what role nutrition and micronutrients play, and what to look for in a high-quality supplement.
A functional disorder of the digestive system. Several factors can play a role and interact – including changes in gut-brain communication, the microbiome and gut motility, as well as hormonal, immunological and lifestyle-related influences. Symptoms range from abdominal pain and bloating to diarrhea or constipation, and vary from person to person.
Women are significantly more often affected by IBS than men.
Current evidence points to an interplay of the gut-brain axis, hormonal influences, the microbiome and individual lifestyle factors.
Made through medical evaluation and by ruling out other conditions with similar symptoms.
Nutrition, movement, stress management and – depending on individual circumstances – adequate micronutrient intake can all be part of a holistic approach to managing IBS.
Why IBS and its symptoms are so complex
For a long time, IBS was viewed mainly as a disorder of the digestive tract. Today, research paints a more nuanced picture: IBS is now understood as a so-called disorder of gut-brain interaction. This means that it's not just the gut itself, but also the communication between the digestive system, the nervous system and the brain that plays a key role.
Signals from the gut – such as stretching, gas or bowel movements – are relayed to the brain via nerve pathways. There, they're not just registered but also "evaluated," shaped by attention, emotions, past experiences and stress.
In IBS, these signals can be processed more intensely or inhibited less effectively. As a result, normal bowel distension may be perceived as uncomfortable or painful sooner than it otherwise would be. This is known as visceral hypersensitivity.
On top of that, IBS presents differently from person to person. While some people mainly struggle with bloating and abdominal pain, others experience diarrhea, constipation, or alternating symptoms. Stress, sleep, diet and hormonal changes can all influence how strongly symptoms are perceived. Some people with IBS also report accompanying symptoms such as back or pelvic pain. While these aren't considered typical IBS symptoms, they may possibly be linked to increased pain sensitivity and the complex interactions between the gut and nervous system.
It's precisely this variety of symptoms that makes IBS so challenging. There isn't one single cause, and therefore usually no single measure that helps every person equally. Instead, it's worth taking a close look at how different contributing factors interact.
IBS in women: which causes may play a role
Why IBS occurs more often in women than in men is currently being researched intensively. Based on today's evidence, there isn't one single cause. Rather, researchers believe that several biological, psychosocial and lifestyle-related factors work together.
Fluctuations in estrogen and progesterone can affect gut motility, pain sensitivity and the communication between the gut and the nervous system. As a result, symptoms may change over the course of the menstrual cycle.
The gut and brain are in close, constant exchange. In IBS, signals from the gut can be perceived more intensely. Sex-specific differences in pain and stress processing may help explain why women are more often affected.
Changes in the gut flora and the gut lining are observed more frequently in people with IBS than in healthy individuals.
Sleep, movement, diet and stress can all influence how strongly – or how often – symptoms occur.
What matters, then, is less the question "What is the cause?" and more the question: "Which factors are interacting in my case, personally?"
This is exactly where modern IBS treatment comes in: instead of searching for a single cause, the focus is increasingly on addressing several contributing factors together.
IBS: diagnosis and treatment
If IBS can have so many different contributing factors, the natural question is: what actually helps?
Before treatment can begin, however, comes diagnosis. IBS isn't identified through a single test. Instead, diagnosis is based on symptoms, medical history and – if needed – examinations that rule out other conditions. That's why it's important to have persistent or new symptoms evaluated by a doctor.
From a scientific standpoint, IBS doesn't lend itself to simple answers. The greatest improvement often comes not from a single measure, but from the interplay of several building blocks. Treatment today is therefore tailored individually to a person's symptoms and possible triggers.
Depending on the situation, approaches such as dietary adjustments, movement, stress management or gut-directed psychological therapies may be appropriate. Medication is also used for certain symptoms. Which measures make sense should always be discussed together with a doctor.
IBS shows up differently for everyone. Take a moment and ask yourself:
- Do your symptoms recur again and again?
- Do they get worse after certain meals?
- Do you feel that stress or emotional strain affects your symptoms?
- Do diarrhea and constipation alternate for you?
- Do you frequently experience bloating, a feeling of fullness or abdominal pain?
✔ Did one or more of these apply to you? A food and symptom diary can help you spot personal patterns. Over two to four weeks, note down:
These notes can also be a valuable basis for the conversation with your doctor.
IBS, nutrition and micronutrients: why a holistic view matters
Nutrition plays a central role for many people with IBS. However, not every gut reacts the same way. While some foods are well tolerated by one person, they may trigger symptoms in another.
That's why the trend today is moving away from blanket restrictions and toward an individual way of eating that's tailored to personal needs. The goal is to avoid unnecessary restrictions while still ensuring a well-balanced supply of all essential nutrients.
Especially for long-term dietary changes, it's worth working with medical professionals or a qualified nutrition counselor to make sure the body continues to receive enough vitamins, minerals and other essential nutrients.
Micronutrient intake is also increasingly moving into the focus of research. While micronutrients aren't considered a treatment for IBS, they serve numerous functions in the body – including for the nervous system, the immune system and energy metabolism.
What to look for in a supplement
Anyone looking to supplement their diet today faces an almost overwhelming range of products. In the greens drink and all-in-one supplement category alone, there are countless offerings advertising a long list of ingredients. But what matters isn't how many ingredients a product contains – it's how sensibly they're combined and what quality stands behind them.
From a scientific perspective, it's worth looking at a few fundamental quality markers.
Good products don't rely on as many individual ingredients as possible, but on a balanced combination of nutrients that complement each other.
Scientifically established ingredients, well-absorbed nutrient forms and transparent labeling are important quality markers.
Trustworthy manufacturers regularly test their products – for example for nutrient content, microbiological purity, and possible contaminants such as heavy metals or pesticides.
A simple routine that fits easily into daily life makes regular use easier and supports long-term consistency.
A holistic approach to comprehensive support for IBS
Especially with IBS, it's not always easy to keep track of every important micronutrient. Anyone who looks into the topic in more depth quickly notices: a single vitamin or mineral is rarely enough for comprehensive support. Instead, several products often need to come together – from vitamins and minerals to pre- and probiotics, plant compounds and other functional ingredients.
For many people, that quickly turns into a demanding routine that's hard to maintain long-term. That's exactly why concepts that bring different nutrient groups together in a single daily routine are gaining importance.
One example of this is BIOGENA ONE. This all-in-one supplement drink was developed to combine vitamins, minerals, pre- and probiotics, plant compounds and other functional ingredients into a single daily routine.
The goal isn't to replace as many individual supplements as possible, but to make science-based micronutrient support simpler, clearer and more practical for everyday life – especially for people who want to consciously supplement their diet without having to combine numerous different products every day.
Ten scientifically studied bacterial strains along with prebiotic fibers like inulin and acacia fiber round out the formula. In a usage observation, 85% of participants reported improved digestion after four weeks. At the same time, bifidobacteria and lactobacilli increased significantly.
Biotin, niacin, riboflavin and vitamin A contribute to the maintenance of normal mucous membranes. The gut lining is the largest mucous membrane in the body and plays an important role not only in digestion, but also for the immune system.
BIOGENA ONE delivers all 13 vitamins, 12 minerals and additional functional ingredients in a single daily serving – so there's no need to combine numerous individual supplements.
The formula is further complemented by 48 plant compounds, 3 amino acids, 2 medicinal mushrooms, 2 algae, 4 carotenoids, coenzyme Q10, beta-glucans and enzymes – for a truly holistic approach to support.
Especially with IBS, many people want to consciously supplement their diet without taking numerous different products every day. BIOGENA ONE brings different nutrient groups together in a single daily routine.
BIOGENA develops and manufactures in Koppl, near Salzburg, Austria. The formula is based on selected branded raw materials and scientifically established nutrient forms. Every batch is additionally tested independently – for traceable quality and safety.
What current observational data shows
In an in-house observational study, many participants reported positive changes in their well-being after just four weeks.
Subjective well-being also developed positively: many participants reported more energy and an overall better quality of life. Observational data like this offers valuable insight into how people experience a daily micronutrient routine in real life. However, it does not replace controlled clinical trials. Everyone responds differently, so individual results may vary.
The first step doesn't have to be complicated
Especially with IBS, many people want one thing above all: more peace of mind in daily life. Less worrying about what they're allowed to eat, which supplements to combine, or whether they've thought of everything.
A holistic, all-in-one approach can help bring the focus back to what matters. Instead of many individual products, BIOGENA ONE relies on a daily routine that combines different nutrient groups sensibly – simple, science-based and easy to fit into everyday life.
- ✅IBS is complex and individual. Symptoms usually don't stem from a single cause. Current evidence suggests that the gut-brain axis, the microbiome, hormonal influences, stress and lifestyle can all interact.
- ✅Women are especially often affected. Hormonal influences, differences in stress and pain processing, and possibly sex-specific characteristics of the microbiome may all contribute. Hormonal fluctuations can also cause symptoms to change over the course of the menstrual cycle.
- ✅There's no single right diet for everyone. Which foods are well tolerated varies from person to person. Blanket restrictions can be unnecessarily limiting. A personal way of eating that accounts for symptoms while still allowing a balanced nutrient intake makes more sense.
- ✅Micronutrient intake should also be considered. Anyone who permanently avoids certain foods or significantly restricts their diet should make sure they continue to get enough vitamins, minerals and other important nutrients.
- ✅A practical daily routine can make a real difference. BIOGENA ONE is one example of a concept that combines vitamins, minerals, pre- and probiotics, plant compounds and other functional ingredients into a single daily routine – designed for people who want to consciously supplement their diet without combining numerous individual products.
- ⚠️Important: Persistent, severe or new symptoms should always be evaluated by a doctor. Dietary supplements can support a balanced diet, but they cannot replace one, and they are not considered a treatment for IBS.
