Diffuse pain, persistent digestive problems, episodes of unexplained fatigue: how many patients present with these non-specific complaints? A growing body of evidence links these symptoms to an imbalance in the gut microbiota and to low-grade inflammation. Understanding and assessing these mechanisms opens up concrete avenues in preventive medicine, beyond symptomatic prescribing alone.
How these approaches enrich clinical practice
Incorporating assessment of inflammatory status and the microbiota allows the practitioner to anticipate certain clinical developments (metabolic syndrome, autoimmune conditions, immune fragility) and personalise interventions. The aim is not to over-medicalise, but to refine clinical analysis in order to identify “at-risk” patient profiles and intervene early.
Echoing Simplycure’s mission, these strategies aim to simplify the implementation of prevention grounded in excellence.
Clinical benchmarks for investigation
Identifying warning signs
A patient presenting with polymorphic symptoms (recurrent digestive problems, alternating diarrhoea and constipation, persistent asthenia) warrants consideration of the microbiota-immunity axis. However, functional causes (dysbiosis, visceral hypersensitivity) should be distinguished from organic causes (IBD, coeliac disease, neoplasia).
Investigations to consider
High-sensitivity CRP and certain faecal markers (calprotectin, lactoferrin) help to distinguish organic inflammation from simple hyperreactivity. The use of microbiota testing should remain targeted, guided by the clinical profile, rather than used for systematic screening.
Adapting interventions: personalising strategies
Nutrition and lifestyle
Dietary adjustments are the first line of intervention: increasing fermentable fibre, reducing fast-releasing sugars, adjusting fat intake. Regular physical activity and good-quality sleep help reduce chronic inflammation.
Considered supplementation
In certain cases, the use of specific probiotics or prebiotics is warranted, but always individualised according to the patient’s terrain (post-antibiotic digestive problems, recurrent infections, irritable bowel syndrome). A common mistake is to use “generic” supplementation without aligning it to the clinical phenotype.
Key takeaway:
- Personalisation takes priority over automation.
- Lifestyle change precedes or complements any supplementation.

5 habits to adopt from tomorrow
- Systematically assess low-grade inflammation in patients with polymorphic symptoms.
- Do not prescribe microbiota tests without a clear clinical indication.
- Introduce fibre and dietary diversity as a first intervention.
- Adapt probiotic supplementation according to the patient’s profile and history.
- Always look for warning signs pointing towards an organic cause.
Key points for your practice
Taking the microbiota and chronic inflammation into account transforms the clinical approach to preventive medicine. These adjustments are not a matter of a “single protocol”, but of a fine-grained analysis of the patient’s terrain. Fully in line with Simplycure’s ambition, these recommendations promote a more proactive, personalised and efficient medicine.
FAQs
Which tests should be recommended first-line to investigate the microbiota?
In routine practice, there is no standardised test recommended for screening. Microbiota work-ups are reserved for specific situations and should be interpreted with caution. Clinical assessment and a few simple inflammatory biomarkers remain the priority.
Are probiotics useful for all patients?
No. Their value depends on the context: history of antibiotic therapy, recurrent infections, functional digestive disorders. The approach should remain targeted and individualised.
How can functional inflammation be distinguished from organic pathology?
Clinical examination and biomarkers provide guidance: elevated CRP and positive calprotectin suggest organic pathology. In case of doubt, referral to a gastroenterologist is essential.
What simple dietary advice should be given to patients with suspected dysbiosis?
Favour a diet rich in varied fibre, limit ultra-processed products and gradually introduce a wider variety of plant foods. These measures form a foundation before any supplementation.
When should probiotic supplementation be avoided?
It should be avoided in severely immunocompromised patients or in cases of suspected active organic pathology that has not yet been investigated (IBD, cancer). Individualisation is essential.
