Conducting assessments of cardiac and thyroid status before initiating lithium therapy is crucial due to lithium's potential side effects on these systems. Lithium can affect thyroid hormone levels, potentially leading to hypothyroidism, which is a known complication for individuals receiving this medication. Monitoring thyroid function tests, such as TSH (Thyroid Stimulating Hormone), helps to ensure that any alterations in thyroid health can be identified early and treated accordingly.

Additionally, lithium can have effects on the cardiovascular system, particularly in patients with pre-existing heart conditions. Evaluating cardiac status through an ECG and assessing for any history of arrhythmias or other cardiac issues is essential to mitigate risks associated with lithium therapy.

In summary, prior assessments of cardiac and thyroid health are integral components of safely initiating lithium therapy, helping to prevent adverse effects related to these systems.
