Hi all, I am female aged 41 and I suffer with bipolar disorder for which I take lithium, a lifeline drug for me. I have regular blood tests as lithium levels need to be checked. Today I have been told that my alt levels have gone from 11 to 160 in five weeks time. My gp said I would have to stop lithium and have a repeat test followed by a scan. He would not discuss with me why my level would suddenly jump up like this. I have been on lithium for 10 years. Any thoughts from any one would be helpful , thank you.
