Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with a doctor.

Without the ability to examine and obtain a history, I can not tell you what the exact cause of the symptoms is. However I will try to provide you with some useful information.

The MRI likely shows an area that is unusually bright in a region called the pituitary. This region can have associated adenomas (tumors) or development abnormalities (Rathke’s Cleft). The labs you show are typical. They assess pituitary function.

You should continue working with your primary physician regarding this finding. You may need to have serial MRIs to follow the size progression. Also, if you have any change in vision, etc, you will need to be seen more urgently. A referral to a neurosurgeon for their opinion would also be an option/recommendation.

Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.

Can you read this commens as you can see where in 2008. I wonder if I should relate this to my problem now to above inf.. Back then I was 34yrs old and next month I'll be 37.  Also, if I should do the cortisol test?

Shoul I continue taking Meg Access and the other pills?

I’m 34 yrs old and I have 4 kids. I never understood why I was always so thing and I hate it. My Dr. gave me Meg Access to gain weight, which I did from 100 pound to 118 now. I'm happy now with my weight. Dr. did the thyroid test and came out that I have THS 23.39HI, Thyroxine (T4) 5.0 and T3 (THYROINE) Total 91. My questions is If I start taking this pills (SYNTHROID 50MCG) Will I loose my pounds again. I don’t want too. Should I continue to taking the Meg Access again? Another thing I just started taking them and feel awful. I feel like  if my glands are going to pop out of my mouth and did not felt like this before. Is this normal.

Treating hypothyroidism does not necessarily cause weight loss -- usually it is weight neutral.  With the hypothyroidism and the history of unintentional weight loss - consider testing adrenal gland (am cortisol should be >11 -- if not needs further testing) to exclude the unlikely but possible diagnosis of Addison's.
