Stress suppresses TSH, [5] and alterations in thyroid hormone levels may arise in psychiatric illness. In major depressive disorder, an NTIS-like phenotype may be observed, with reduced T3 and increased rT3. T4 may be elevated, and TSH is usually normal, although TSH's normal circadian rhythm may be disrupted. [2]
The most common type of hyperthyroidism, Graves' disease, may additionally cause eye problems (Graves' ophthalmopathy) and skin changes of the legs (pretibial myxedema). [6] Thyroid disease may also cause muscle weakness in the form of thyrotoxic myopathy, but this is constant rather than episodic. [5]
