I was diagnosed hypo back in 2017 with hypothyroidism. Prior to this diagnosis my T4 was teetering around the bottom of the range for about 8 months of testing dropping below and sitting right at the bottom. Not really changing that much. My TSH gradually and consistently went up over that period until it went over range and I was diagnosed. I had symptoms for many months prior to going to GP at the start of that 8 month period and was really struggling by the time I was diagnosed.
I have had many many TPO and TG abs tests and s have been negative.
In 2018 after a number of months of hyper symptoms was diagnosed with Graves’ disease with a positive TSI ab test.
This went into remission and I am now hypo again on 100mcg of Levo.
I assumed the cause of my hypothyroidism was probably antibody negative hashis (as I have graves so another autoimmune disease is more likely so this seemed probable).
Have seen a private GP recently who thought I may have a thyroid nodule as she could feel something on exam and my TSH is very slow to respond to low T4 levels and more recently is jumping about with no changes in meds. I also often feel like I have a lump in my throat. So she recommended a thyroid scan.
Thyroid scan shows my thyroid is perfectly healthy! No nodules, no hashis, thyroid is a normal size, normal blood flow! This is great but what on earth could be going on. What is causing my hypothyroidism? And my weird TSH. Could there be a pituitary problem?
I also have PCOS.
Any thoughts from the wonderfully knowledgable people on this forum?....
My DH thinks I am a medical mystery.....
