Symptoms and Signs of Thyroid Problems

Doctor's Notes on Thyroid Problems

Problems or diseases with the thyroid range from underactivity or overactivity of the thyroid gland (hypothyroidism or hyperthyroidism, respectively), nodules or lumps in the gland, inflammation of the gland (thyroiditis), and cancers of the thyroid gland. The cause of these conditions varies depending on the exact type of thyroid problem that is present.

Just as the causes of thyroid problems vary, the symptoms and signs of thyroid problems vary widely according to the exact type of thyroid disease. Associated symptoms and signs of thyroid problems can include enlargement of the thyroid gland (goiter), the presence of lumps or nodules within the thyroid gland, weight gain or loss, menstrual irregularities, skin and hair changes, constipation, muscle weakness, racing heart or slow heart rate, and changes in energy or mood.
