Can Thyroid Problems Cause Anxiety?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 20th, 2026.
Yes, thyroid problems can cause anxiety and panic-like symptoms. Both hyperthyroidism (overactive thyroid) and hypothyroidism (underactive thyroid) can trigger anxiety disorders. Hyperthyroidism affects approximately 1.2% of the US population and commonly causes rapid heart rate, nervousness, and panic attacks due to excess thyroid hormone production. Hypothyroidism, affecting about 5% of Americans, can cause anxiety through hormonal imbalances and metabolic changes. Studies show that up to 60% of people with hyperthyroidism experience anxiety symptoms. The thyroid gland regulates metabolism, heart rate, and nervous system function, so disruptions create physical sensations that mimic or trigger anxiety disorders.
