Thyroid Disorders
Endocrinologist
Overview
Thyroid disorders occur when the thyroid gland produces too little (hypothyroidism) or too much (hyperthyroidism) hormone. This affects metabolism, energy levels, heart rate, and weight. Blood tests can confirm diagnosis.
When to see a doctor
See a doctor if you have unexplained fatigue, weight changes, palpitations, sensitivity to cold or heat, or swelling in the neck. Thyroid screening is recommended for at-risk individuals.
More information
An endocrinologist manages thyroid conditions. Hypothyroidism is treated with thyroid hormone replacement; hyperthyroidism may require medication, radioactive iodine, or surgery.
