Thyroid & Anxiety: How Thyroid Affects Your Mood
Thyroid disorders commonly cause anxiety: hyperthyroidism speeds everything up, causing jitteriness, racing heart, and panic-like symptoms; hypothyroidism causes low mood and brain fog. Treating the thyroid often resolves or significantly improves anxiety.
Thyroid and mood
Thyroid hormone directly affects brain chemistry and nervous system function.
- Hyperthyroidism: anxiety, irritability, racing heart, tremor.
- Hypothyroidism: depression, brain fog, apathy.
- Treating thyroid often resolves mood symptoms.
- If anxiety persists after treatment, address it separately.
