The thyroid is a small gland responsible for producing hormones that play a crucial role in many of the body’s systems — from cells and tissues, to organs like the heart, brain, liver, and kidneys. Dysfunction occurs when the thyroid produces either too much or too little thyroid hormone. Either can disrupt healthy functioning of vital organs — leading to a wide range of symptoms. The good news? Once diagnosed and treated, it’s entirely possible to live a normal, healthy life.

5 reasons to check your thyroid

1) It's a small gland with a major impact

​The thyroid is a small, butterfly-shaped gland at base of the neck that produces thyroid hormones; these influence how all other cells, tissues, and organs function.

2) Thyroid dysfunction can have hundreds of possible symptoms

​Symptoms vary widely and diagnosis can be difficult, so keeping detailed records will be a significant help to your doctor.

3) It affects millions

It's estimated that over 30 million Americans have thyroid dysfunction, yet at least half of these cases are undiagnosed and, consequently, untreated.

4) ​Anyone can be affected by thyroid dysfunction

Although women are five times more likely to develop thyroid problems than men, it can happen to anyone. ​

5) Diagnosis is the key​

​Good news: With a proper diagnosis, thyroid dysfunction can be successfully treated so you can enjoy a healthy lifestyle.
