A 24-year-old patient started a new antidepressant 3 months ago which has helped her sleep. She has noticed, however, that none of her clothes fit anymore, and when she weighed herself she saw that she had gained 6 kg.

She has a background of Hashimoto’s thyroiditis, so her GP organises some TFTs:

TSH 3.9 mU/L² (0.4-4)

Free T4 21.3 pmol/L (9-24)
