Thyroid Dysfunction as a Neglected Driver of Comorbidity in the Era of Non Communicable Diseases

Thyroid dysfunction represents one of the most common endocrine disorders globally, yet its broader implications for non communicable diseases (NCDs) remain insufficiently recognized within health care systems and international health policy frameworks. Despite a high preva-lence of both overt and subclinical thyroid disorders, their contribution to the onset, progres-sion, and complexity of major NCDs—including cardiovascular disease, metabolic disorders, cognitive decline, and reduced quality of life—has been systematically underprioritized. As the global burden of NCDs continues to rise, particularly in aging populations, addressing this oversight is becoming increasingly urgent.Emerging evidence demonstrates that thyroid dysfunction interacts with multiple physiological pathways central to NCD risk. Even mild deviations in thyroid hormone levels are associated with increased incidence of hypertension, dyslipidemia, atrial fibrillation, heart failure, insulin resistance, and bone fragility. Subclinical hypothyroidism has been linked to accelerated ath-erosclerosis and impaired cardiac function, while subclinical hyperthyroidism significantly in-creases the risk of arrhythmias, fractures, and dementia. These relationships are especially concerning because they often occur in individuals whose thyroid abnormalities remain undi-agnosed or untreated. Yet, current NCD prevention strategies rarely include systematic screening for thyroid dysfunction, despite the potential for early intervention to mitigate disease progression and reduce long term health care costs.At the policy level, thyroid disorders are notably absent from most global NCD action plans—even within the World Health Organization’s current frameworks—despite fulfilling core criteria for inclusion: high prevalence, substantial morbidity, availability of cost effective diagnostics, and effective treatments. This gap reflects a longstanding fragmentation between endocrine health and broader public health priorities. Consequently, clinical guidelines also vary widely between countries, and many health care providers lack standardized approaches for integrat-ing thyroid assessment into routine NCD risk evaluation.Furthermore, the comorbidity burden associated with thyroid dysfunction is amplified by de-mographic trends. Aging populations, increased exposure to environmental disruptors, and rising obesity rates all contribute to higher susceptibility to thyroid disease and its complica-tions. These intersecting trends underscore the need for a reoriented global strategy that rec-ognizes thyroid dysfunction not merely as an isolated endocrine disorder but as a significant modifier of NCD trajectories across the life course.This abstract argues for the urgent integration of thyroid dysfunction into national and interna-tional NCD policy agendas. Strengthening awareness among clinicians, improving population-level screening strategies, and adopting harmonized clinical guidelines could substantially reduce the hidden burden of thyroid-related comorbidities. A renewed focus from organizations such as WHO, combined with interdisciplinary collaboration between endocrinology, cardiolo-gy, geriatrics, and public health, is essential for addressing this overlooked dimension of NCD management. By elevating thyroid dysfunction within global health priorities, health systems may achieve earlier detection, more targeted treatment, and improved long-term outcomes for millions of individuals at risk.The proposal will cover the following topics, but not be exclusively limited to those:Cardiovascular disease as risk factors of comorbidities from thyroid dysfunction, Metabolic disorders as risk factors of comorbidities from thyroid dysfunction, Cognitive decline, and risk factors of comorbidities from thyroid dysfunctionReduced quality of life, and risk factors of comorbidities from thyroid dysfunctionReduced bone health, and risk factors of comorbidities from thyroid dysfunctionReduced Quality of life, and risk factors of comorbidities from thyroid dysfunctionRisk of thyroid dysfunction on comorbidities in patients with multinodular thyroid glandsRisk of thyroid dysfunction on comorbidities during pregnancyRisk of thyroid dysfunction on comorbidities during influence of thyroid endocrine disrupting chemicalsRisk of thyroid dysfunction on comorbidities during influence of other environmental influences such as e.g. thyroid, selenium and iron.The case of risk of thyroid dysfunction on comorbidities during influence of autoimmunity in other organs Topic editors: Ulla Feldt-Rasmussen, Grigoris Effraimidis, Marianne Klose Source: https://www.frontiersin.org/research-topics/78593/thyroid-dysfunction-as-a-neglected-driver-of-comorbidity-in-the-era-of-non-communicable-diseases
