Comparison of Warfarin Dosages and International Normalized Ratios Before and After Roux‐en‐Y Gastric Bypass Surgery

Structured PICO

Does Roux-en-Y gastric bypass surgery affect warfarin dosages and INR in patients taking warfarin?

Population

Patients taking warfarin who undergo Roux-en-Y gastric bypass (RYGB) surgery

Intervention

Roux-en-Y gastric bypass (RYGB) surgery

Comparator

Before RYGB surgery

Outcome

Warfarin dosages and International Normalized Ratios (INR)surrogate

Warfarin dosages tend to decrease after RYGB surgery, highlighting the need for increased INR monitoring in these patients.

Abstract

Warfarin dosages tended to decrease after RYGB surgery, in agreement with previously published literature. These findings suggest the need for increased INR monitoring and patient education for patients taking warfarin after RYGB surgery.
