Causes Subacute thyroiditis is an uncommon condition. It is thought to be the result of a viral infection. The condition often occurs a few weeks after a viral infection of the ear, sinus, or throat, such as mumps, the flu, or a common cold.Subacute thyroiditis occurs most often in middle-aged women with symptoms of a viral upper respiratory tract infection in the past month. Symptoms The most obvious symptom of subacute thyroiditis is pain in the neck caused by a swollen and inflamed thyroid gland. Sometimes, the pain can spread (radiate) to the jaw or ears. The thyroid gland may be painful and swollen for weeks or, in rare cases, months.Other symptoms include:Tenderness when gentle pressure is applied to the thyroid gland Difficulty or painful swallowing, hoarseness Fatigue, feeling weak FatigueFatigue is a feeling of weariness, tiredness, or lack of energy.Read Article Now Book Mark Article FeverThe inflamed thyroid gland may release too much thyroid hormone, causing symptoms of hyperthyroidism, including:HyperthyroidismHyperthyroidism is a condition in which the thyroid gland makes too much thyroid hormone.

Medicines such as aspirin or ibuprofen are used to control pain in mild cases.More serious cases may need short-term treatment with medicines that reduce swelling and inflammation, such as prednisone. Symptoms of an overactive thyroid are treated with a class of medicines called beta-blockers.If the thyroid becomes underactive during the recovery phase, thyroid hormone replacement may be needed. Outlook (Prognosis) The condition should improve on its own. But the illness may last for months. Long-term or severe complications do not often occur.The condition is not infectious. People cannot catch it from you. It is not inherited within families like some thyroid conditions. When to Contact a Medical Professional Contact your health care provider if:You have symptoms of this disorder. You have thyroiditis and symptoms do not improve with treatment. Prevention Vaccines that prevent viral infections such as the flu may help prevent subacute thyroiditis. Other causes may not be preventable.Open ReferencesReferencesBrent GA, Weetman AP.

For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).Endocrine glandsillustrationThyroid gland - illustration The thyroid gland, a part of the endocrine (hormone) system, plays a major role in regulating the body's metabolism.Thyroid glandillustrationEndocrine glands - illustration Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body.
