Re: symptoms of pituitary gland tumor...obesity?
I have a pituitary tumor and I'm not overweight. They really aren't sure right now what mine is secreting. Possibly ACTH, which would mean Cushings Disease. Symptoms include weight gain, irregular periods, hair growth, acne, stretch marks, a hump on the back of the neck, and a moon shaped face. They suspect I haven't had weight gain because I also have an adrenal gland problem.
It won't hurt to be tested. Have them check prolactin, acth, cortisol (preferably 24 hour urine), tsh, and growth hormone.
Another thing that can cause acne and hair growth is the adrenal problem I have, late onset congential adrenal hyperplasia. They can start to check for this by testing your androgen levels. The next step would be an acth stimulation test.
I hope that helps!
