Comprehensive Blood Tests
Given your health profile and the observations shared, the first step should be to undergo comprehensive blood tests.
These tests should include a complete thyroid panel (TSH, Free T4, Free T3, Reverse T3, and thyroid antibodies) to closely monitor your hypothyroidism.
Additionally, checking for vitamin D levels, B12, iron, and a complete blood count (CBC) could provide insights into your dry skin and depression symptoms.
Understanding these levels can help tailor your treatment more effectively.
