Thyroid disorders, affecting over 200 million people globally19, remain a critical public health challenge. As we mark World Thyroid Day 2025 on May 25th, this article explores the day’s history. It examines global and regional trends. The article also looks at Nepal’s evolving thyroid landscape. Additionally, it provides actionable steps for prevention and management.
History of World Thyroid Day
World Thyroid Day (WTD) was established in 2008 by the European Thyroid Association (ETA)115. It aims to spotlight thyroid health. It also combats misinformation. The date commemorates the ETA’s founding anniversary (May 25, 1965)39. By 2010, global endocrine societies started endorsing WTD. This included the American Thyroid Association and Asian Oceanic Thyroid Association. Their endorsement transformed it into a worldwide movement1518.
Yearly Themes have addressed pressing issues:
- 2018: Lifestyle and diet changes for thyroid management1.
- 2019: Early detection and treatment1.
- 2021: Iodine’s role in maternal and child health1.
- 2023: “Thyroid Health: Nurturing Well-being”1.
- 2025: “Thyroid Health: Know It, Check It, Conquer It”4, emphasizing proactive screening and personalized care.
Global and Regional Thyroid Health Trends
Global Burden
- Prevalence: Thyroid diseases are the second-most common endocrine disorder after diabetes, impacting 10% of adults globally114.
- Cancer: Thyroid cancer accounts for 3.1% of global cancer cases, with higher incidence in Asia (72.6%)11.
- Iodine Deficiency: Over 1 billion people live in iodine-deficient regions, increasing risks of goiter, hypothyroidism, and developmental delays68.

Types of THYROID Disorders
Thyroid diseases encompass a spectrum of conditions affecting the thyroid gland, each with unique diagnostic approaches, treatments, and visibility. Early detection and management are paramount for optimal health outcomes. The most prevalent thyroid disorders include hypothyroidism, hyperthyroidism, goiter/iodine deficiency disorders, Hashimoto’s thyroiditis, and thyroid cancer.
Hypothyroidism: Characterized by insufficient thyroid hormone production, hypothyroidism can manifest at any age. Congenital hypothyroidism, particularly common in India (affecting approximately 1 in 2640 newborns), necessitates prompt diagnosis and treatment to avert potential brain damage. Delayed diagnosis is often attributed to limited awareness and inadequate screening programs.
Hyperthyroidism: This condition arises from an overactive thyroid gland, leading to accelerated metabolism. Symptoms of hyperthyroidism may include weight loss, hand tremors, and a rapid or irregular heartbeat.
Goiter/Iodine Deficiency Disorders: A goiter refers to an enlarged thyroid gland, which may or may not be associated with altered thyroid function. Research in India has established a strong correlation between iodine deficiency and endemic goiter, particularly in Himalayan regions. Iodine deficiency can lead to hypothyroidism in newborns, prompting the Indian government to implement a salt iodization program. This initiative has effectively reduced the incidence of congenital hypothyroidism in Uttar Pradesh.
Hashimoto’s Thyroiditis: Also known as Hashimoto’s disease, this autoimmune disorder involves the body’s immune cells attacking the thyroid gland. An Indian study revealed that among girls with goiter, 7.5% had juvenile autoimmune thyroiditis, encompassing Hashimoto’s thyroiditis.
Thyroid Cancer: Thyroid cancer involves the development of malignant cells within the thyroid gland tissues. While thyroid nodules are common, they are not always cancerous. Several types of thyroid cancer exist, and the risk of developing thyroid cancer can be influenced by factors such as age, gender, and radiation exposure.
Prevention and Management Strategies
Key Prevention Methods
- Iodized Salt: Ensure consumption of adequately iodized salt (15–40 ppm)8.
- Regular Screenings: Annual TSH tests for high-risk groups (women, seniors, diabetics)47.
- Dietary Balance: Incorporate selenium (nuts, eggs) and zinc (legumes, meat) to support thyroid function17.
- Stress Management: Chronic stress exacerbates autoimmune thyroid conditions17.
- Avoid Processed Foods: Limit goitrogens (soy, cruciferous vegetables) in excess17.
Managing Thyroid Disorders
- Hypothyroidism: Levothyroxine replacement therapy with regular dose adjustments517.
- Hyperthyroidism: Antithyroid drugs, radioiodine, or surgery57.
- Thyroid Cancer: Surgery followed by radioiodine ablation or targeted therapy11.

Frequently Asked Questions
Q1: What are common thyroid symptoms?
A: Fatigue, weight fluctuations, mood swings, and neck swelling. Hypothyroidism often causes weight gain and cold intolerance, while hyperthyroidism leads to weight loss and palpitations59.
Q2: How does iodine deficiency affect Nepal?
A: Despite iodized salt success, remote areas still face deficiency, linked to goiter and developmental delays816.
Q3: Is thyroid cancer treatable?
A: Yes. Nepal’s new oncology centers and HPV vaccines aim to improve outcomes711.
Q4: Can lifestyle changes help?
A: Absolutely. Stress reduction, balanced diets, and avoiding smoking reduce risks117.
Conclusion
The focus of World Thyroid Day 2025 is on addressing thyroid health in Nepal. Rising disorders coexist with iodine excess challenges. By leveraging policy reforms, community screening, and global partnerships, Nepal can turn the tide. **nowItCheckItConquerIt – Schedule your TSH test today and share this resource to amplify awareness!
