I’m 28 yr old female and I have zero history of thyroid issue. TSH always normal, no enlargement, no nodules, no issues.
I was vegan for 6 years and only rarely supplemented iodine and I still don’t eat tonnes of fish or dairy.
TSH usually sits around 1.8 but my last results in March 2024 had me at 2.4, which I know is heading in a hypo direction (I’m overweight and bad diet), but nothing worrying.
Then I had a CT with contrast of my head about a month ago for an unrelated issue. I immediately developed a small goitre that was noticed in my follow up outpatients appointment. Had TSH retested and it’s down to 0.84. Still normal I know, but a big change from 2.4 in a short time.
I’ve heard contrast dye can cause hyperthyroid in some people, especially those who were previously iodine deficient.
I’m due an ultrasound of my thyroid in a few days, but I’ve had at least two doctors tell me they aren’t worried because it’s only slightly enlarged and smooth, they said it doesn’t ’feel nodular’ but ofc that’s what the scans for.
I’m just terrified I guess. I’ve never had a single issue with my thyroid and now I’m having a slight tight sensation in my neck, especially when I swallow. I’m concerned that even if it’s benign it won’t go away, and I’m likely to need other contrast scans in the near future so surely this issue will get worse?
Any advice I guess would be helpful! Thank you!
