All of these activities are your body's metabolism.Thyroid problems includeGoiter - enlargement of the thyroid glandHyperthyroidism - when your thyroid gland makes more thyroid hormones than your body needsHypothyroidism - when your thyroid gland does not make enough thyroid hormonesThyroid cancerThyroid nodules - lumps in the thyroid glandThyroiditis - swelling of the thyroidTo diagnose thyroid diseases, doctors use a medical history, physical exam, and thyroid tests.
