Outcome Measures

Primary Outcomes (1)

  • Gastrointestinal Tolerance and Treatment Compliance in Iron Deficiency Anemia Patients Using Oral Iron with or without Lactobacillus plantarum 299v Probiotic Supplementation

    To investigate gastrointestinal tolerability and treatment compliance in patients with iron deficiency anemia who received oral iron replacement therapy with versus without concomitant Lactobacillus plantarum 299v (L. plantarum 299v) probiotic supplementation. Gastrointestinal intolerance symptoms (loss of appetite, nausea, vomiting, abdominal pain, diarrhea, constipation, and bloating) will be assessed using a structured questionnaire with yes or no questions. Measurement Tool: Structured Questionnaire Data Collection Points: Baseline, within the first 30 days of iron replacement therapy (IRT), and at any time during the 3-month IRT. Scale Description: The questionnaire will include yes or no questions to determine the presence of gastrointestinal intolerance symptoms. A "yes" response indicates the presence of a symptom, and a "no" response indicates its absence.

    3 months

Study Arms (2)

IRT-Only

NO INTERVENTION

Iron deficiency anemia patients receive iron replacement therapy alone.

IRT-Pro

EXPERIMENTAL

Iron deficiency anemia patients receive iron replacement therapy plus L. plantarum 299v probiotic support

Dietary Supplement: Lactobacillus plantarum 299v probiotic support

Interventions

Addition of Lactobacillus plantarum 299v (L. plantarum 299v) probiotic supplementation to iron replacement therapy.

IRT-Pro
