Description
Mark your calendars for World Thyroid Day – May 25, a day dedicated to the unsung hero of your body — the thyroid gland. This special day brings attention to thyroid diseases like hypothyroidism, hyperthyroidism, and everything in between. And guess what? We’re going to unpack everything for you in an easy, friendly, and engaging way!
History
The thyroid was first noted by ancient Greeks, but it wasn’t really understood until centuries later in medical literature.
By the 17th century, anatomists clearly identified the gland, although its purpose was still a mystery to most.
In 1811, iodine was discovered by a French chemist named Bernard Courtois — a major breakthrough for thyroid research.
This little mineral would go on to become a superhero in the fight against thyroid diseases.
By the early 20th century, doctors discovered that iodine deficiency caused goiter, a swelling of the thyroid gland.
Adding iodine to salt soon became a global public health movement, drastically reducing goiter rates around the world.
In 1923, the American Thyroid Association was born, gathering brilliant minds to advance research, treatment, and education.
The ATA remains a cornerstone of thyroid research and plays a key role in supporting World Thyroid Day – May 25.
