is blood transfusion required during bariatric surgery?

Dr. Kenneth Foreman
Bariatrics 28 years experience
Rarely: Though there may be circumstances where transfusion is indicated, the vast majority of patients who undergo laparoscopic bariatric surgery have very little blood loss and therefore do not need blood transfusion.
Dr. Chakshu Gupta
Pathology 23 years experience
Rarely: This procedure is associated with minimal loss of blood. A transfusion will be needed if there is unexpected bleeding.

Very rarely: Blood transfusion is very rare after bypass or any bariatric surgery. Overall about 1 in 200 chance. Make sure you stop aspirin.
Dr. Christopher Evanson
General Surgery 24 years experience
Very rare: Approx 1-2% overall. Higher in patients that take "blood thinners", Aspirin products, and anti-inflammatory meds close to surgery.
