vertigo is common -- even amongst non-thyroid patients -- The GERD meds may interfere with absorption of thyroid meds so would recheck thyroid levels in 6-8 weeks after starting such medications. Same with estrogen -- through a different mechanism. The antivert should not interfere.
This seems to be common, amongst a number of hypothyroid patients. Are you taking thyroid hormone medications?
Estrogen/BC Pills may interfere with your thyroid levels (need to adjust meds).
Have you had recent blood tests for your thyroid? If so, what are your values? You can request copies, in case you do not have them.
As for GERD medications, they too can interfere with medications (absorption).
If you read this before Dr. Lupo has a chance to reply, list your medications and when you take them.
If you have access to your thyroid labs, list them as well.
Best,
