Outcome Measures

Primary Outcomes (1)

  • Recruitment rate

    This will be documented as total number of individuals recruited and randomized in the study.

    One year

Secondary Outcomes (3)

  • Glycemic control

    Baseline, Intra-op, 1, 6, 12, 24 and 48 hours post-op

  • Wound infection

    At follow up visit with surgeon at approx. 6 weeks post-surgery

  • Length of Hospital Stay

    One year

Study Arms (2)

Metformin

ACTIVE COMPARATOR

Metformin, dosage same as the patient's regular dosage

Drug: Metformin

Placebo

PLACEBO COMPARATOR

Placebo

Drug: Placebo

Interventions

The study intervention involves Type II Diabetes Mellitus patient self-administered metformin vs. placebo according to regular dosing schedule and randomization. Both placebo and active drug will be over-encapsulated by pharmacy so that they will be indistinguishable to the personnel involved in the study.
