IBS is more than an upset stomach
Irritable Bowel Syndrome (IBS) is a common and long-term condition that affects the digestive system and can significantly impact daily comfort and quality of life. It is estimated to affect 10–15% of the population, with a higher prevalence among women aged 20 to 40. However, IBS can also affect children and older adults.
IBS is typically associated with a range of gastrointestinal symptoms, including abdominal discomfort, bloating, and irregular bowel habits. These symptoms vary between individuals, making the condition complex and often requiring a personalized approach to management.
What May Influence IBS?
Although the exact causes of IBS remain unclear, several contributing factors are widely recognized:
- Dietary habits (such as fermentable carbohydrates or high-fat foods)
- Stress and psychological factors
- Hormonal changes
- Alterations in the gut microbiome
Recognizing the signs of IBS – When your gut speaks up
Irritable Bowel Syndrome (IBS) is a common but often misunderstood condition that can significantly affect quality of life.
Symptoms may vary in intensity and type from person to person and can shift over time, making IBS a complex condition to manage.
- Common symptoms of IBS include:
- Abdominal pain or cramping
- Changes in bowel movements, including:
- Diarrhea (IBS-D) – frequent, loose stools
- Constipation (IBS-C) – infrequent or hard stools
- Mixed (IBS-M) – alternating between diarrhea and constipation
- Bloating and gas – a sensation of fullness or increased intestinal pressure
- Urgency for bowel movements – sudden and strong need to go
- Mucus in stool
- Feeling of incomplete evacuation
- Fatigue and disturbed sleep
- Food sensitivities – some individuals report symptom triggers from foods such as dairy, gluten, or high-fat meals
What Does Research Say About Probiotics and IBS?
Scientific interest in the gut microbiome’s role in Irritable Bowel Syndrome (IBS) has grown significantly in recent years. Research increasingly explores how imbalances in the microbial ecosystem and disruptions to the intestinal barrier may be involved in IBS symptomatology.
Some studies have examined how specific strains of probiotics may help maintain a balanced microbial environment and support normal digestive function. However, the effects are strain-specific—meaning that not all probiotic strains are equally effective, and their benefits may vary depending on individual needs and conditions.
Choosing the Right Probiotic Matters
Not all probiotics are the same. For those with IBS, it may be relevant to choose a product formulated with several well-characterized bacterial strains. A multi-strain approach may support key aspects of gut health, such as microbial diversity, the intestinal lining, and immune interactions—areas often discussed in the scientific literature in relation to IBS.
Choosing a scientifically developed product—one that prioritizes quality, diversity, and documented characteristics—can make a meaningful difference in how the probiotic interacts with your gut environment.

Frequently asked questions about IBS
IBS can be confused with several conditions that have similar symptoms.
Examples:
- Inflammatory bowel disease (Crohn's disease, ulcerative colitis)
- Celiac disease and lactose intolerance
- Microscopic colitis
- Giardia infection or histamine intolerance
These conditions can cause stomach pain, gas, or diarrhea. If symptoms change, the cause should be investigated by a healthcare professional. Doctors can use blood tests, endoscopy, or stool analysis to distinguish IBS from other diagnoses.
There is no universal method for alleviating IBS, but many people experience improvement with calmer eating habits, a gentle diet, regular exercise, and reduced stress.
Common strategies:
- Eat smaller portions at a leisurely pace
- Drink enough water
- Try probiotics with carefully selected bacterial strains, which can help maintain a balanced microbial environment in the gut and support normal digestive function.
- Keep a food diary to identify what triggers your symptoms.
Since the gut is affected by both diet and stress, regular routines and mental well-being can contribute to a calmer stomach. Research shows that the brain-gut axis plays a central role in IBS.
People with IBS often react to foods high in fermentable carbohydrates (FODMAPs).
onions, garlic, beans, lentils, certain fruits, and dairy products containing lactose.
Fatty, strongly spiced foods, coffee, alcohol, and carbonated drinks can also aggravate symptoms. Since the gut reacts individually, it is important to identify your own triggers, preferably with the help of a dietitian. Research shows that diet and stress levels affect the sensitivity and balance of the gut.
