Digestive wellbeing

Bloating, reflux and bowel-transit problems

Bloating, irregular transit, discomfort after meals or reflux: these symptoms are common and do not always have a precise diagnosis. This page is the entry point when the cause is not yet established; with a confirmed diagnosis (IBS, IBD, coeliac disease), the matching page is more suitable.

Yogurt bowl, oats, berries, ginger and kombucha for digestive comfort

Alert: Any sudden pain or blood in stool requires urgent medical advice.

Common indications

IBS, bloating, reflux, irregular transit

Method

Dietary review, soluble fibre, FODMAP if indicated

How nutrition can help

Step 1: basics of digestive comfort

Before any complex protocol, four simple habits resolve a large share of the discomfort.

  • Three meals at regular hours, slow chewing
  • 1.5 to 2 L of water per day, moderate coffee and alcohol
  • Reduce fizzy drinks, chewing gum and sweeteners
  • Gradually introduce soluble fibre (oats, psyllium, cooked carrots)

Step 2: low-FODMAP diet (if necessary)

For persistent IBS, a 4- to 6-week low-FODMAP diet, followed by a gradual, personalised reintroduction, improves symptoms in 70 to 75% of patients. This protocol must be supervised by a trained dietitian to avoid deficiencies and unnecessary long-term restrictions.

This diagram shows the FODMAP protocol, a tool reserved for irritable bowel syndrome and some functional digestive complaints, always under dietetic supervision. It does not apply to food allergies or coeliac disease, and it does not replace medical advice.

What belongs to your physician

Diagnosis, tests and medical treatment remain your doctor's responsibility. Dietetic support adapts to them and, with your agreement, a report is sent to your doctor.

Preparing your appointment

Your first consultation, in practical terms

The initial assessment consultation (anamnesis) lasts 60 minutes, both within the CNS-covered pathway and as a private consultation. Here is what is useful to bring and what is covered.

Useful to bring

  • Reports of any tests already carried out (endoscopy, breath tests, coeliac serology) if you have them.
  • The list of foods you have already removed, and for how long.
  • If you already have a food record, you are welcome to bring it.
  • Your medical prescription and social security card if CNS coverage is intended.

What is explored

  • Nature, frequency and timing of symptoms in relation to meals.
  • Meal regularity, chewing, drinks and sensitivity to stress.
  • Fibre intake and the exclusions already in place, with their nutritional impact.
  • Whether a FODMAP protocol is relevant — it is not indicated in every case.

What you may receive

  • The basic digestive-comfort steps, applicable from the following week.
  • If a FODMAP protocol is indicated: the markers for the current phase and the reintroduction schedule.

How progress is assessed

  • How symptoms change between two consultations, based on your own record.
  • A check that the diet stays varied enough and sufficient in fibre.
  • Follow-up takes place in dedicated 30-minute consultations, at the practice or by video. Their pace is agreed with you, with no fixed frequency.

If the recommendations are hard to follow

An exclusion that is too hard to sustain is eased rather than forced through: the elimination phase is temporary by design. If it weighs on daily or social life, the reintroduction schedule is revised in consultation, or the protocol is replaced by simpler adjustments.

Frequently asked questions about digestive problems

A low-FODMAP diet temporarily (4 to 6 weeks) reduces the fermentable carbohydrates behind IBS bloating and pain. It is followed by a gradual, personalised reintroduction.

Basic habits (chewing, meal regularity, gradual soluble fibre) bring relief in 2 to 4 weeks. A supervised FODMAP protocol improves symptoms in 70 to 75% of patients in 4 to 6 weeks.
