I'm going for a repeat TSH today because my previous test was a little off. The Dr. said it could have been a fluke and says it's his policy to repeat tests prior to prescribing treatment. Okay, I respect that approach. However, I explained to him that my thyroid has always been barely in the normal range, but he still wants to repeat. I told him about my microadenoma (small tumor on the pituitary gland that causes hyperprolactinemia or in other words, I lactate ALL the time.) He ordered an MRI and thankfully, the tumor is the same size. However, he did not want to treat the hyperprolactinemia with Parlodel or Dostinex (rx'd by my OB/GYN during pregnancy or else I wouldn't have been able to sustain my 3 pregnancies and have my 3 beautiful children. My OB/GYN is now retired). So here's my question: Can the pituitary microadenoma cause hypothyroid problems? I have EVERY thyroid symptom in the book, but as I said, my TSH keeps coming back barely normal. I exercise daily on the treadmill for 30 minutes going 3.5 mph and on an incline, eat less than 1200 calories a day and STILL can't lose weight! I am 5'7" and 167 pounds-the heaviest I've ever been. I only weighed 140 pounds when I got pregnant with my 1st child, lost the weight down to 150, lost it again after baby #2 down to 150lbs and now after baby #3 (he's 16 months) I'm struggling at 167lbs! I've lost 2 pounds in the past six weeks in spite of my desperate attempts. Keep in mind, I also chase my 3 little tornadoes all day, so I am by no means a couch potato--I don't even like TV! I am tired all the time, even though I get 7-9 hours sleep at night. Please help! I want to feel great again, not tired and depressed. My children deserve to have me the best that I can be.
