Dear Mayo Clinic: I just turned 30 and recently was diagnosed with Hashimotoâs thyroiditis. Iâm wondering about whether it can be cured or if I will have to take medication for the rest of my life. Iâve read the Autoimmune Protocol (AIP) diet may help. Is this true? Do you have any suggestions for managing symptoms?A: Hashimotoâs thyroiditis is an autoimmune condition that usually progresses slowly and often leads to low thyroid hormone levels â a condition called hypothyroidism. The best therapy for Hashimotoâs thyroiditis is to normalize thyroid hormone levels with medication. A balanced diet and other healthy lifestyle choices may help when you have Hashimotoâs, but a specific diet alone is unlikely to reverse the changes caused by the disease.Your thyroid is a small, butterfly-shaped gland at the base of the front of your neck.
