The aim of this study was to investigate whether consumption of probiotic fermented milk containing Bifidobacterium bifidum YIT 10347 improves symptoms in patients with functional gastrointestinal disorders (FGID). Thirty-seven FGID patients (18 male, 19 female) aged 12–80 years (mean ± SD, 52.6 ± 17.5 years) whose condition had not improved despite being seen at several medical institutions consumed 100 mL/day of B. bifidum YIT 10347 fermented milk for 4 weeks. Symptoms were evaluated after the enrollment period (BL: baseline), sample consumption period (CP) and 4 weeks after the CP (FP: follow-up period). Gastrointestinal symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS) and the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG); psychological symptoms were evaluated using the Profile of Mood States (POMS) short form. Concentrations of salivary stress markers and the oxidative stress marker urinary 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured. GSRS subscale scores for abdominal pain, diarrhea, and constipation significantly improved relative to BL after consumption of the fermented milk, as did FSSG subscale scores for symptoms of acid-related dyspepsia. Some subjective psychological symptoms improved. POMS scores significantly improved, and "Anger-Hostility" subscale scores significantly decreased after the consumption period, while "Vigor" subscale scores marginally increased during the consumption period. The concentrations of urinary 8-OHdG and the stress marker salivary cortisol were significantly lower at CP but returned to baseline levels at FP. Continuous consumption of B. bifidum YIT 10347 fermented milk is expected to improve gastrointestinal symptoms and reduce psychological stress in FGID patients.
