Can hyperthyroid patient recover. what food can help ?

Depends on type: There is no evidence that any specific food will be helpful in treating hyperthyroidism. The first step in treatment is to determine the type of hyperthyroidism; once this is known the patient and physician can decide together whether the best approach is medications, radioactive iodine, surgery, or observation (if the process will resolve on its own).

No food: Hyperthyroidism due to graves' or subacute thyroiditis may regress - but no foods will help.

Generally not: While true hyperthyroidism can "burn itself out" after many years, it is not safe or appropriate to allow it to do so. Several therapies are readily available for true hyperthyroidism. No specific food or health food store supplements are of any help. You need the services of a qualified physician.
