What is typically monitored in addition to lithium levels for patients taking lithium?

Monitoring thyroid function in patients taking lithium is essential due to the risk of lithium-induced thyroid dysfunction. Lithium has a well-documented association with hypothyroidism, which can manifest as fatigue, weight gain, and various other symptoms that may overlap with mood disorders. Because lithium affects the thyroid gland, it’s important to routinely check thyroid hormone levels, particularly TSH (thyroid-stimulating hormone), to ensure that the thyroid remains functioning properly while the patient is on lithium therapy.

This proactive monitoring can help in early detection of any thyroid-related issues, allowing for timely intervention, such as adjusting lithium dosage or considering thyroid hormone replacement therapy if necessary. Regular thyroid function tests are a standard part of the management plan for patients on long-term lithium treatment, highlighting the importance of integrated care in psychiatry.
