If you are going to have Rhinoplasty, try to have consultation with your surgeon at least two weeks before surgery. You should inform him if you have medical condition and what kind of medication you are recently getting. This is really one of the important points, as some of medications can cause serious complications in the recovery period. That's why, you might need to change your medication for alternate one at least two weeks before surgery and for the first weeks after. It is better to stop using supplements at least two weeks before surgery. Synthetic components involved in supplement preparation, may cause worsening in swelling. Your doctor should give you a list of supplements that you would need to stop immediately, as they may cause bruising after surgery. All the recommendations and restrictions should be individualised. The common rule usually is to stop blood thinners - and take vitamin C all the week prior to surgery. Fruits, pineapple and proteins are welcome. The most serious restriction always is consuming alcohol and smoking - stop them at least 3 weeks before surgery. I wish you the best of luck..
