Both hypothyroidism and hyperthyroidism are prevalent forms of thyroid disease that impact millions of individuals throughout the world.
Hypothyroidism refers to an underactive thyroid gland (that does not produce enough thyroid hormone), this can be caused by autoimmune thyroid disease, thyroid cancer treatment, certain medicines, a malfunctioning pituitary gland, or the excessive intake of certain foods.
Hyperthyroidism is a condition where the thyroid gland produces more thyroid hormones than is needed by the body, an overactive thyroid gland. This can be caused by a condition called Grave’s disease (an autoimmune disorder), an enlarged thyroid gland (goitre), or thyroiditis (temporary inflammation of the thyroid gland).
