Last week diagnoised with overactive thyroid possibly, graves disease. Dr told me today that my liver function mildly abnormal. Do you think related?

Liver and thyroid. Patients with graves hyperthyroidism often have mild elevations in liver enzymes. The elevated alk phos may actually be from bone due to rapid turnover. Mild alt elevation could be from increased liver metabolism, blood flow, maybe some hypoxia, but is usually not indicative of damage. Get the thyroid treated, and all this should normalize.
