Hey; I'm getting a tonsillectomy in less than a week, and I was wondering if I need to get off birth control before going under surgery, or would it have no affect at all?

It is well known that oral contraceptives increase the risk of venous thromboembolic disease.
If one does not have any other 'personal risk factors' or 'disease factors' for venous thromboembolism, generally, oral contraceptives need not be stopped prior to surgery.
However, there is no consensus regarding this.Similar thing can be said about hormone replacement therapy (HRT) & surgery.
It is perhaps very important for one to know
- as to how many risk factors one has (more the risk factors, more is the overall risk),
- if there are any risk factors related to the disease one has (for ex, malignancy-esp. pelvic, paraneoplastic syndromes etc), &
- risk related to the kind of surgery, its duration etc.
Some anesthetic drugs and other drug interactions may also add to the risk of thrombogenicity.
Sometimes, oral contraceptives may need to be stopped prior to surgery for other reasons. One such reason is "Porphyria". Oral contraceptives cause destruction of the heme group in cytochromes, requiring new heme for incorporation into cytochromes.This can precipitate an acute porphyria.
