Recovery times for pituitary tumor surgery can vary depending on the size and location of the tumor, the type of surgery and your overall health. Generally, patients will need to stay in the hospital for a few days and then recover over the course of a few weeks or sometimes a few months. Patients who get transsphenoidal surgery may experience headaches or congestion for a week or two after the procedure but often return to their usual activities within six weeks. Your physician may also monitor your hormones or other aspects of your health and prescribe medication to help you stay healthy as you recover.
