I had gastric sleeve surgery on 6//10/15 and partial thyroidectomy on 8/18/15 to remove fist sized benign mass. I have lost 106 pounds since my gastric sleeve and now I am experiencing EXTREME dizziness several times daily. I'm having trouble getting my daily recommended protein amounts and I'm wondering if that alone can cause dizziness/ vertigo or if the thyroidectomy could be the cause?
