It's nice to see that others have been left in the dark about this as well! I have experienced extreme fatigue for a good portion of my life. I'm 22 years old and have never felt youthful and full of energy as many say I should. I just ignored it always thinking I was lazy. Finally I went to the doctor and discovered I had a pituitary gland tumor. But my neurologist keeps wanting to treat me for seizures and thinks that the tumor isn't a problem because it's so small. But after doing research on my own, I'm starting to learn that the tumor could be the cause of the seizures and possible other symptoms I have experienced. I.e. fatigue, clumsiness, short term memmory issues, slight vision problems. I'm about to go crazy paying all the copays and testing fees and taking different drugs for depression and epilepsy. What is wrong with me!!

 Here are a link I think may be helpful to others. If anyone has any insight about what I'm dealing with PLEASE share! I'm sick of wasting my life away hoping to feel better.

HI SUE, I HAD SEVERAL PITUITARY ADINOMAS AND A GREY MUSHY AREA OF THE PITUITARY, WHICH WAS FOUND WHEN I HAD SURGERY IN 1977. I WAS TOLD AT THE TIME THAT I HAD PROBABLY HAD THE TUMORS ALL MY LIFE. I HAVE LEARNED THAT A VAST MAJORITY  OF PEOPLE HAVE PITUITARY TUMORS AND NEVER KNOW IT. ALSO, FOR THE MOST PART, THEY ARE ALMOST ALWAYS BENIGN PITUITARY ADIMONAS (TUMORS)  AND THERE IS NO NEED FOR SURGERY. HAVING HAD THE SURGERY, AND HAVING EXPERIENCED NO CHANGES IN MY HEALTH, I WOULD COMPLETELY AGREE WITH THE DOCS ON THIS ONE. UNLESS THE ADINOMA CAUSES A PROBLEM, JOEY CAN LIVE HIS ENTIRE LIFE WITHOUT ONE SINGLE PROBLEM FROM THAT ADINOMA. I UNDERSTAND HOW FRIGHTENING IT CAN BE TO HEAR NEWS LIKE THAT. MY FIRST THOUGHT WAS GET THOSE OUT OF MY HEAD. HINDSIGHT, I WOULD NOT HAVE HAD THE SURGERY. THE PROCEEDURE THEY WERE USING THEN CAUSED ME A GREAT DEAL OF PROBLEMS AND I HAVE BEEN PLAGUED WITH ENDOCRINE AND ALLERGY PROBLEMS SINCE THEN. OF COURSE, THEY HAVE NOW HAD MANY YEARS TO LEARN MORE ABOUT THE PITUITARY, ITS FUNCTIONS AND THE NECESSITY FOR SURGERY. I HAD SEIZURES AFTER THE SURGERY, NOT BEFORE. FOR HIS SAKE, I WOULD DEFINITELY LISTEN TO THE DOCS. LIKE I SAID, HE CAN HAVE IT HIS ENTIRE LIFE AND NEVER HAVE A PROBLEM BECAUSE IT IS THERE. ALWAYS MAKE SURE YOU GET OPINIONS FROM SEVERAL DOCS BEFORE YOU EVER EMBARK ON ANY SURGERY, ESPECIALLY BRAIN SURGERY.....FROM ONE WHO KNOWS.....GOD BLESS YOU AND JOEY, JAN
