This note is a response to Peetiepie. Hi Peetiepie. Headaches and nausea are hard to deal with. My daughter’s pituitary adenoma was removed at Mayo a very long time ago and there has been no regrowth. These adenomas come with many variations according to what area of the tiny pituitary gland the growth is on, and thus which symptoms are produced. My daughter’s symptom was lactation. The premedication was unsuccessfull in reducing the size of the growth. Surgery was required. The surgery was through her nose. While seemingly not invasive, it is a very small and risky surgery, because you are entering the brain. I hope that you are under the care of a team. Your visual field needs to be monitored, as well as regular followup imaging. Do your research on reliable sites, and dont be afraid to ask questions to your healthcare TEAM. These things sre justifiably scary. Knowledge and clarification can reduce fear. Good luck with this!
