I have been experiencing lightheadedness and dizziness on and off for months maybe longer. I had what felt like a series of panic attacks recently my blood test showed mild hypothyroid then Hashimoto. Panic has stopped with 25mg of Levothyroxine but only have been seeing a PA - who didn’t think the ‘attacks’ were related. I’m still feeling off at times and it seems like it’s somehow correlates with meals - i sometimes feel like crap 45 min to an hour after I eat. Anyone have anything like this? I see an endocrinologist next week praying he says yeah it’s your thyroid here’s how we fix it - i dread a long road of trial and error with meds and diet.
