Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Metformin ER

The subjects developing GI-related symptoms with metformin will be randomized to Metformin Extended Release (ER)

Drug: Metformin Extended Release Oral Tablet
Metformin Extended Release Oral Tablet is standard of care for diarrhea in patients taking metformin

Experimental: Psyllium

The subjects developing GI-related symptoms with metformin will be randomized to Psyllium

Drug: Psyllium powder
To evaluate whether Psyllium will alleviate diarrhea

Outcome Measures

Primary Outcome Measures

  1. Birmingham Irritable Bowel Syndrome (IBS) Symptom Questionnaire [3 months]

    This scale is based on symptoms that frequently occur in IBS cases, examines abdominal discomfort status, stool properties, and defecation feelings. The scale includes a total of 11 items, with 6 possible grades for each item that range from 0 points (never having this symptom) to 5 points (the symptom is always present). The total score is the sum of the scores for each item. The Total score is used. No "subscale" is used. Total range is minimum=0, maximum=55. The higher values represent a worse outcome.
