my realization I was hypo was a weight gain of 10lbs in six weeks- so you should be worried. Get thyroid tests...if you are tired, have dry skin, sleep a ton and never poop these are all signs. Hope you find answers!
I'm with utah on that one. How about liver or pancreas? Would have those checked REALLY REALLY closely as well.
Ask your doctor to run a complete set of labs including a complete thyroid panel with antibodies and CBC (complete blood count). Have they done any scans? (MRI, CT, x-rays?) Weight gain like that is not commonly simply thyroid related - I'm wondering if you have a cyst that is growing quickly somewhere in your body (ovarian, abdominal??)
