Intestinal dysbiosis and Irritable Bowel Syndrome (IBS) are very common and often related conditions. Functional intestinal disorders affect approximately 1 in 10 people (in Italy), with a higher prevalence among females and in more active age groups, when stress, irregular rhythms and disordered eating can have a greater impact on intestinal balance.
In adolescents and young adults, dysbiosis is often linked to previous intestinal infections or an unbalanced diet; in those over 60, factors such as a sedentary lifestyle, reduced fiber intake, and prolonged use of medications become more relevant. Hormonal changes can also influence intestinal motility and the perception of visceral pain.
The good newsDysbiosis and IBS are often "improvable" conditions. An integrated approach that combines targeted nutrition, nutritional supplementation and a healthy lifestyle can concretely contribute to improving symptoms and quality of life.
Dysbiosis and IBS: What They Are and What's the Difference?
What is intestinal dysbiosis?
Dysbiosis is a altered balance of the intestinal microbiota, which may concern the composition or functionality of microorganisms. It is not a pathology in itself, but a condition that can accompany stress, a low-fiber diet, intestinal infections, antibiotic therapy, or a sedentary lifestyle.
The most common disorders associated with dysbiosis include:
- swelling and flatulence
- bowel irregularities
- persistent tiredness
- increased intestinal sensitivity
What is Irritable Bowel Syndrome (IBS)?
IBS is a functional intestinal disorder characterized by recurrent abdominal pain associated with changes in the frequency or consistency of bowel movements. Different forms are distinguished: IBS-D (predominantly diarrhea), IBS-C (predominantly constipation), IBS-M (mixed pattern) and IBS-U (unclassified).
Even in the absence of obvious organic lesions, IBS involves:
- visceral hypersensitivity;
- alterations in intestinal motility;
- dysfunctional gut-brain communication;
- frequent association with dysbiosis.
It is possible to have dysbiosis without IBS, but In IBS, dysbiosis is very common and represents an important intervention target.
Why do dysbiosis and IBS develop?
Among the main factors involved we find:
- Western diet, low in fiber and high in sugars, saturated fats, refined flours and alcohol;
- use of drugs, especially antibiotics, proton pump inhibitors, some laxatives or anti-inflammatories;
- chronic stress and insufficient sleep, which influence the gut-brain axis;
- sedentary lifestyle, which causes an underproduction of beneficial metabolites such as butyrate by the microbiota;
- increased permeability (“leaky gut”), which promotes micro-inflammation and hypersensitivity.
In the case of IBS, neuroimmune and hormonal factors also come into play, amplifying the perception of pain and intestinal irregularity.
Nutrition and Intestine: What to Focus on (and Avoid) Every Day
Some dietary principles are useful for both dysbiosis and IBS:
- “Smart” fiber: it is better to increase it gradually, favoring soluble ones (oats, psyllium, legumes if tolerated);
- Good fats and quality proteins (EVO oil, dried fruit, fish, eggs): taken in good quantities, they reduce low-grade inflammation;
- Regular meals and moderate portions, to promote more balanced motility;
- Adequate hydration, customized according to individual needs (30–35 ml/kg/day).
Low-FODMAP approach (especially IBS)
Temporarily reduce fermentables (oligo-, di-, mono-saccharides and polyols) for 4–6 weeks, then guided reintroduction to identify the most triggering classes.
In the initial phase, it is especially important to limit wheat and rye (bread, pasta), cow's milk (lactose), some legumes and vegetables (onion, garlic, cauliflower), fruit rich in free fructose (apple, pear), polyol sweeteners (sorbitol, mannitol), and some honeys/syrups.
Instead, choose rice, oats, quinoa, well-tolerated vegetables (zucchini, carrots, spinach, cucumbers, tomatoes), low-FODMAP fruit (unripe bananas, strawberries, citrus fruits), lactose-free dairy products or plant-based alternatives, and lean proteins.
In any case, it will be a temporary measure: the low-FODMAP diet aims to personalize tolerance, avoiding unnecessary restrictions that could worsen the diversity of the microbiota.
Some specific advice, divided by the different forms:
“Gas-generating” dysbiosis (visible swelling/flatulence)
- Limit: fast sugars, alcohol, carbonated drinks, excess raw cruciferous vegetables and unprocessed legumes;
- Promote: gentle cooking (steaming, stewing), soaking and rinsing legumes, long-leavened doughs, soluble fibre, carminative herbs (mint, fennel), ginger.
IBS-D (diarrhea prevalence)
- Be careful with caffeine, alcohol, chili pepper, fried fats, polyol sweeteners;
- Replace: well-cooked and cooled starches (resistant starch), rice, potatoes, and unripe bananas; psyllium in small doses is often helpful.
IBS-C (constipation prevalence)
- Water + soluble fiber (psyllium/oats) + daily exercise.
- Limit crude insoluble fiber if it increases pain.
- Kiwi (2/day) and prunes can be helpful for many people.
Practical advice "starting tomorrow morning"
- Breakfast: Hot drink + oatmeal (or rice/corn porridge) with chia/psyllium seeds; low-FODMAP fruit (kiwi or strawberries).
- Lunch: Rice or rice/corn pasta + gently sautéed zucchini and carrots; raw extra virgin olive oil; oily fish or tofu.
- Dinner: Boiled and cooled potatoes (resistant starch) + eggs/tempeh and cucumber/fennel salad; herbs (mint, parsley).
- Snacks: small amounts of nuts/almonds, lactose-free yogurt if tolerated.
- Routine: 30–40 minutes of brisk walking; 10 minutes of deep breathing before bed; regular meal times.
- Beverages: Drink water in small sips throughout the day; limit alcohol, carbonated drinks, and excessive coffee.
Lifestyle: How important are smoking, alcohol, stress, insomnia, and anxiety?
Intestinal health does not only depend on what we eat, but we must also take into account:
- Smoke: alters microcirculation and inflammation; associated with worse symptom control.
- Alcohol: especially beer, sparkling wines and spirits irritate the mucous membranes and can promote diarrhea and fermentation.
- Chronic stress: increases cortisol, alters motility and permeability; mind-body techniques (breathing, mindfulness, muscle relaxation, biofeedback) are as key tools as diet.
- SleepDeprivation and irregular schedules worsen visceral hypersensitivity. Sleep hygiene (consistent sleep schedules, light in the morning, and reduced screen time in the evening) is a "therapy" for the gut-brain axis.
- Anxiety and moodBrief psychological interventions, CBT, and gut-directed hypnotherapy have been shown to be effective in IBS; they complement (not replace) nutritional approaches.
Can physical activity help? Which one to choose?
Exercise modulates motility, improves microbiota diversity, and reduces stress and inflammation. In general, the weekly target should be at least 150–300 minutes of moderate aerobic activity (brisk walking, cycling, swimming) or 75–150 minutes of vigorous activity, plus two strength training sessions.
Some specific advice, divided by the different forms:
- IBS-C: Daily brisk walking, abdominal mobility, moderate-intensity core and strength exercises; yoga and Pilates are excellent for improving breathing and vagal tone.
- IBS-D: Regular but not excessive activity; avoid maximal exertion before lunch/dinner if it triggers urgency; introduce diaphragmatic breathing post-workout.
- Post-infectious dysbiosis: gradual recovery; beware of overloading, which can temporarily increase permeability.
Targeted nutritional supplementation: focus on NUTRIFARMA products
A well-constructed integration strategy allows you to act on the different mechanisms that contribute to dysbiosis and irritable bowel syndrome (IBS):
- rebalancing of the microbiota,
- protection of the mucosal barrier,
- modulation of low-grade inflammation,
- reduction of visceral hypersensitivity,
- optimizing immune function.
Below, we analyze in detail the main NUTRIFARMA formulations best suited to these conditions.
