Lymphocytic Thyroiditis Overview

What is lymphocytic thyroiditis?
A person with lymphocytic thyroiditis has inflammation and enlargement of the thyroid gland. The immune system, which normally fights infection, mistakenly attacks thyroid cells. Lymphocytes, which are part of the immune system, collect in the thyroid gland. Initially, the thyroid gland becomes overactive, resulting in symptoms of hyperthyroidism. After a period of overactivity, the thyroid gland becomes underactive, resulting in symptoms of hypothyroidism. Lymphocytic thyroiditis is the most common form of thyroiditis in children.

What are the symptoms of lymphocytic thyroiditis?
Lymphocytic thyroiditis initially causes symptoms of hyperthyroidism, such as absent menstrual periods, anxiety, nervousness, diarrhea, fatigue, heat intolerance, excessive sweating, palpitations, muscle cramps, rapid speech, rapid pulse, weight loss, and neck swelling. Later this can progress to symptoms of hypothyroidism.

How does the doctor treat lymphocytic thyroiditis?
Treatment for lymphocytic thyroiditis may include beta-blockers and thyroid hormone supplements.
