This will cause various kinds of bio-chemical effects. There are many kinds of such functional tumors and each will show different signs and symptoms.

Now, if your Pituitary tumor is an ACTH tumor, then the hormone that will be produced is adrenocorticotropin. This hormone tells your adrenal gland to produce the hormone cortisol.
