I saw that hypothyroidism does not cause food sensitives/allergies, but what about the other way around? i've read articles that say you can away from certain foods but can that exacerbate the thyroid issue if you have food allergies/sensitivities?

Unclear question. Allergies do not cause hypothyroidism and hypothyroidism does not cause allergies. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV and Covid vaccines. Wish you good health!
