Hello, and thank you for your question. You might want to avoid soda before rhinoplasty. It is always best to stick with drinking water prior to surgery. In fact, we recommend drinking lots of water because it helps the body function better on a cellular level, helping in the recovery process. Most sodas contain caffeine, which can be mildly dehydrating. However, protocols vary from surgeon to surgeon and will depend on the patient’s particular case. I recommend scheduling an in-person consultation with a reputable board-certified facial plastic surgeon, particularly one with a strong rhinoplasty portfolio. Your surgeon can discuss all the dos and don’ts before surgery, ensuring you have the smoothest recovery possible. Hope that helps.
