Good evening! My mom has had a tumor in her pituitary gland for the past 15 years. She was put on medication for it. Over time she has also been diagnosed with diabetes insipidus, Addison's disease, and vertigo. Two weeks ago, the doctor removed a portion of the tumor. Since she has been home, all she wants to do is sleep. I spoke to her prior to typing this message, and she doesn't feel well. She told me that she fell recently, but she doesn't remember doing it. She doesn't have much of an appetite, so she has to force herself to eat. Can anyone explain to me what might be happening to her body?
