Subacute thyroiditis is generally referred to as subacute thyroiditis, and depending on the condition, some require medication and some do not. Subacute thyroiditis is a self-limiting disease associated with viral infection. Inflammation is not likely to spread, most patients with mild cases can be self-healed, usually without special treatment. However, a very small number of patients may develop permanent hypothyroidism and require lifelong thyroid hormone replacement therapy. Patients should focus on high-calorie, high-protein, high-vitamin, easy-to-digest foods. Limit high-fiber diet, avoid eating iodine-rich food, avoid coffee, strong tea and other excitatory drinks. A reasonable diet is conducive to the recovery of the condition. If subacute thyroiditis appears fever, goiter, neck pain and other symptoms, when the symptoms are serious and can not be self-healing, you should go to the hospital in time, follow the doctor’s instructions for symptomatic treatment, and give glucocorticosteroids if necessary, to avoid delaying the condition.
