The Claim

Chronic stress may contribute to the development and progression of autoimmune thyroid diseases, such as Hashimoto’s thyroiditis and Graves' disease, through modulation of neuro-immune-endocrine pathways including the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS), leading to altered cortisol levels and immune cell activity, which may trigger autoimmunity against thyroid proteins like thyroperoxidase (TPO) and thyroglobulin (Tg).

In plain English

Long-term stress might mess with your body’s stress and immune systems in a way that could lead to thyroid problems like Hashimoto’s or Graves’ disease, possibly by causing the immune system to attack the thyroid by mistake.

See the scientific wording

Chronic stress may contribute to the development and progression of autoimmune thyroid diseases (AITDs), including Hashimoto’s thyroiditis and Graves' disease, by modulating neuro-immune-endocrine pathways such as the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS), which alter cortisol levels and immune cell activity, suggesting stress-related physiological changes could play a role in triggering autoimmunity against thyroid proteins like thyroperoxidase (TPO) and thyroglobulin (Tg).

  1. Study: Understanding Thyroid Autoimmunity: A Mini Review on the Role of Stress and Immune Activation

    The study looks at how long-term stress affects the body's immune system and thyroid, and it finds that stress can trigger the immune system to attack the thyroid, which supports the idea that stress plays a role in thyroid autoimmune diseases.
