World Thyroid Awareness Day, observed on May 25, 2025, highlights the importance of thyroid health and aims to raise global awareness about thyroid disorders, affecting millions of people across all age groups. The thyroid is a small gland in the neck. It plays a critical role in regulating metabolism, energy levels, heart rate, and overall bodily functions. In 2025, the focus is on early detection, awareness, and the importance of timely treatment, with healthcare professionals urging people not to ignore persistent signs that may point to thyroid imbalances. By recognising the impact of thyroid health on daily life, World Thyroid Awareness Day 2025 encourages proactive healthcare and informed conversations around this often-overlooked gland. Thyroid disorders typically fall into two main categories: hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid). A simple blood test (TSH, T3, T4) can determine if your thyroid is functioning properly. Early detection and treatment can significantly improve quality of life.
