What is the outlook for a patient with thyroiditis?

In the case of Hashimoto's thyroiditis, the resulting hypothyroidism is generally permanent. People who develop subacute thyroiditis usually have symptoms for 1 to 3 months, but complete recovery of thyroid function can take up to 12 to 18 months. These people have about a 5 percent chance of developing a permanent condition of hypothyroidism.

The time frame for recovery to a thyroid that functions normally for post-partum, silent or painless thyroiditis is also about 12 to 18 months. People with these conditions have about a 20 percent chance of developing permanent hypothyroidism.
