Many patients are not aware of the possible adverse events that can happen during surgery if they consume herbal supplements. Patients are advised to disclose to their doctors of the types of herbal supplements they are taking prior to surgery. They are also advise to stop taking these herbal supplements about 2 weeks before surgery.
Some of these herbal supplements can cause significant bleeding, heart problems, blood pressure changes and drug interactions. This would have an effect on the possible surgical complications and surgical outcome. Therefore patients should also seek their doctor's advice if they wish to resume their herbal supplements after surgery.
