World Thyroid Day is marked on 25 May.  The day is dedicated to raising awareness about the disease, its study and treatment.

Thyroid disease is a group of disorders that affects the thyroid gland. The decision to celebrate World Thyroid Day on 25 May was taken in 2007 in Germany's Leipzig.


This year, the key message of the day is "Thyroid and Communication".

What is its significance?

The thyroid gland produces triiodothyronine (T3) and thyroxine (T4), which play a big role in controlling the body's metabolism.

 If the gland produces either too much or too little of the hormones, it can lead to difficulties in sleep, digestion, blood pressure and much more.

The day assumes special significance amid the ongoing COVID-19 pandemic.

Thyroid-related illnesses are on the rise and awareness about it is important as the it impacts an individual’s mood and body functions on a day-to-day basis. 


This day offers members from thyroid associations around the world an opportunity to highlight issues related to the medical condition. 

These groups also work to provide the public with information related to treatment of thyroid diseases, as well as the ways to prevent it through appropriate iodine nutrition.
