Q&A: I had a pituitary adenoma removed and have concerns for my next pregnancy.

Both are.

I agree that if the surgery was successful then you shouldn't worry about the adenoma that was removed. This is a benign structure, the cure for which is removal -- and that's been done.  The "hormone" checks your new doctor will want are probably tests to see if there are any more adenoma effects in the blood stream which may indicate incomplete removal or return of more adenoma.

You'll probably do just fine with this pregnancy, but your new doctor is the one who has ultimate responsibility for your care and wants to watch you very carefully -- just because you're someone who has shown she can develop this unusual problem.

Paranoid doctors get the best results, even if they spin your wheels a little more than the more casual doctors.  If you think you're getting good obstetrics, then be a sport and let your doctor feel you need more watching, because there is nothing wrong with being overwatched when there's a baby involved. After all, you are all on the same side.
