Hi Fred / Rich I have elevated liver enzymes (e.g. ALT about 3 x max range) and ultrasound scan showed my liver is "moderately fatty". Blood testing has ruled out all the standard causes of this and I don't drink any alcohol. Also, my serum ferritin has been about 20% above max range for a while. Do you commonly see this in people with B12 deficiency ? I have a range of standard B12 deficiency symptoms. Many thanks !
