Thyroid
Organ / systemThe small gland that sets your body's tempo — energy, weight, mood, and temperature.
What toxicants do here
Dioxins and PFAS disrupt the hormone signals the thyroid runs on; radiation can damage the gland directly.
Because the thyroid sets the tempo for so many systems, when it drifts the effects ripple into nearly every part of how you feel.
What targets it — tap to learn each one
Hypothyroidism is an Agent Orange presumptive; thyroid cancer can be radiation-presumptive; PFAS are linked to thyroid disease.
An under- or over-active thyroid worsens energy, weight, and mood and strains the heart. A simple thyroid panel (TSH and more) checks it.
Bring this to your clinician and your VSO — they decide what testing and care, if any, is right for you. For general, whole-person ways to support your body, see Whole health.
