    Silent thyroiditis

    Lymphocytic thyroiditis; Subacute lymphocytic thyroiditis; Painless thyroiditis; Thyroiditis - silent

    Silent thyroiditis is swelling (inflammation) of the thyroid gland, in which the person alternates between hyperthyroidism and hypothyroidism.

    Causes

    The cause of this type of thyroiditis is unknown. The disease affects women more often than men.

    Symptoms

    The earliest symptoms result from an overactive thyroid gland (hyperthyroidism). These symptoms may last for 3 months or fewer. Later symptoms may be of an underactive thyroid (including fatigue and cold intolerance) until the thyroid recovers.

    Symptoms are usually mild and may include:

    • Fatigue
    • Frequent bowel movements
    • Heat intolerance
    • Increased appetite
    • Increased sweating
    • Irregular menstrual periods
    • Irritability
    • Muscle cramps
    • Nervousness, restlessness
    • Palpitations
    • Weakness
    • Weight loss

    Exams and Tests

    A physical examination may show:

    • Enlarged thyroid gland
    • Rapid heart rate
    • Shaking hands

    Tests may show:

    • Decreased radioactive iodine uptake
    • Increased blood levels of the thyroid hormones T3 and T4
    • White blood cells (lymphocytes) on a thyroid biopsy

    Treatment

    Treatment is based on symptoms. Beta-blockers relieve rapid heart rate and excessive sweating.

    Outlook (Prognosis)

    Generally, silent thyroiditis will go away on its own within 1 year. The acute phase will end within 3 months.

    Some people may develop hypothyroidism over time. Regular follow-ups with a doctor are recommended.

    When to Contact a Medical Professional

    Call your health care provider if you have symptoms of this condition.
