Eksperimentel: L. reuteri DSM 17938
|
L. reuteri will be administered at 1x10^8 CFU dosage in form of tabs.
In order to ensure colonization (run in), 4 tabs will be administered per os daily (4x10^8CFU/die) for 15 days.
Then administration will continue with 2 tabs daily (2x10^8 CFU/die) for 90 days.

Improvement in gastrointestinal symptoms after 3 months of probiotic administration
Tidsramme: Before the start of the study (Time 0) and after 90 days of treatment (Time 90)
|
Validated and structured questionnaires to evaluate gastrointestinal symptoms, to confirm functional constipation diagnosis and to exclude IBS variant constipation.

Changes in physiological parameters after 3 months of probiotic administration
Tidsramme: Before the start of the study (Time 0) and after 90 days of treatment (Time 90)
|
Physiological parameters: Quali/Quantitative evaluation of the colonic transit time (TTC) with radiopaque markers (qualitative study : RX after 3 days from the 20 markers assumption.
Quantitative study: RX after 3 days from the assumption of 10 markers a day for 6 days in patients with TTC delayed), non invasive evaluation of gastric electrical activity and gastric emptying time (cutaneous electrography (EGG) and 13C octanoic acid breath test).
The evaluations will be performed at baseline, after 45 days of treatment and at the end of treatment
