Q: I have had my pituitary tumor surgically removed, do I still need to come in for regular visits? A: Yes. Any patient with a pituitary tumor needs regular visits to the endocrinology department both pre- and post-operatively. The site of a pituitary tumor is a special site, unlike other tumors in the skull, it grows in a functional area. To meet the needs of different ages, genders and different physiological periods, the pituitary gland and hypothalamus secrete different levels of hormones. Hormone levels must be maintained within a certain demand range to meet the various needs of the body, and hormone secretion cannot be high or low, so they need to be measured and adjusted regularly. The duration of follow-up can vary from one month to one year or 2-3 years, but long-term lifelong follow-up is necessary.
