NCT07276009

Brief Summary

The goal of this clinical trial is to learn whether a multi-strain probiotic can reduce digestive symptoms and improve quality of life in adults with functional dyspepsia. The main questions it aims to answer are:

  • Does the probiotic reduce symptoms such as fullness after meals, bloating, stomach discomfort, and early satiation?
  • Does the probiotic improve emotional well-being, including stress, anxiety, and mood? Researchers will compare the probiotic to a placebo (a look-alike capsule with no active ingredients) to see if the probiotic truly helps adults with functional dyspepsia. Participants will:
  • Take one capsule of the probiotic or placebo once daily before meals for 60 days
  • Complete questionnaires about their digestive symptoms at the start, 1 month, and 2 months
  • Complete surveys on stress, anxiety, depression, and quality of life at the start and 2 months
  • Attend scheduled study visits for checkups and assessments

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18-65 years
  • Diagnosis of Functional Dyspepsia based on Rome IV criteria, with symptoms present for at least 3 months, and symptom onset at least 6 months before diagnosis, including:
  • Postprandial fullness
  • Early satiation
  • Epigastric pain or burning
  • (with no evidence of structural disease explaining symptoms)
  • Moderate to severe symptom severity at baseline, as defined by a validated scale (e.g., NDI or global symptom score)
  • Normal upper GI endoscopy within the last 12 months (or at screening), excluding structural disease (e.g., peptic ulcer, malignancy)
  • Negative for H. pylori (either previously treated successfully or tested negative within study screening)
  • Ability and willingness to provide informed consent and comply with study procedures
  • Stable medication use, if any, for at least 4 weeks before screening (e.g., PPIs, antidepressants, laxatives)

You may not qualify if:

  • Evidence of structural GI disease (e.g., peptic ulcer, gastric cancer, celiac disease) on recent or screening endoscopy
  • History of gastrointestinal surgery affecting stomach or small intestine (except appendectomy or cholecystectomy)
  • Positive test for H. pylori during screening (or untreated known infection)
  • Current or recent use (within 4 weeks) of antibiotics, pre-, pro- or postbiotics, unless part of study protocol
  • Use of medications affecting GI motility (e.g., prokinetics, opioids, anticholinergics) within 2-4 weeks before enrollment
  • Overlap with other functional GI disorders (except IBS) if they are the dominant complaint, unless your protocol allows overlap
  • Clinically significant psychiatric illness (e.g., major depression, schizophrenia) that may interfere with symptom reporting or adherence
  • Severe systemic or metabolic disease (e.g., uncontrolled diabetes, renal or hepatic failure)
  • Pregnancy or lactation, or intention to become pregnant during the study period
  • Participation in another clinical trial within the past 3 months
  • Known allergy or intolerance to study product components
