Yes, increasing Thyronorm to 62.5 mcg is a reasonable and cautious step for TSH 5.6. In a 72-year-old with liver disease and hypertension, the TSH target should be more relaxed — around 4–6 µIU/mL is acceptable; aggressive over-correction risks atrial fibrillation and bone loss in the elderly. The incremental increase from 50 to 62.5 mcg is appropriate. Note that liver disease can affect T4 metabolism, which may explain the fluctuating TSH responses.

Yes

Yes thyronorm 62.5 is appropriate given that there was a good compliance with thyronorm 50 .
