The Impact of COVID-19 on Thyroid Health: Mechanisms, Disorders, and Long-Term Implications
The COVID-19 pandemic has brought numerous health challenges, one of which is the emerging concern regarding thyroid damage. Research has demonstrated that COVID-19 can significantly affect the thyroid gland through various mechanisms, leading to different thyroid disorders with potential long-term implications. The Mechanisms of Thyroid Damage COVID-19, caused by the SARS-CoV-2 virus, impacts multiple organs, including the thyroid gland. The virus employs the ACE2 receptor to infiltrate cells, and these receptors are abundantly found in the thyroid gland, even more than in the lungs. This high expression of ACE2 makes the thyroid particularly vulnerable to direct viral invasion and damage. Two primary mechanisms have been proposed for thyroid damage in COVID-19 patients: Direct Viral Effect: SARS-CoV-2 can directly infect thyroid cells, causing inflammation and thyroiditis. This direct cytopathic effect can disrupt normal thyroid function and structure. Indirect Immune-Mediated Effec...
