Hello, I have had slowly increasing mild elevations of liver enzymes over the last 9 months when they were initially discovered.I had taken venlafaxine 300mg and mirtazapine for 20 years for severe OCD. The previous 5 years I have had chronic fatigue syndrome which has been incapacitating for the last two years in particular with symptoms of ibs symptoms, extreme fatigue, mental fog and back pain.Depression and OCD has worsened also.Since the elevation of the liver enzymes I have changed medication to fluoxetine as venlafaxine was believed to be the cause of this but mental health is worse and no improvement in liver tests I am a 40 year old woman with pcos.My current alt levels are around 70, ggt 180,alp 134 and have had slow steady increases. Ultrasound showed only slight fatty changes.Do you think my worsening exhaustion could be partly related to liver?Should I have any further investigations for this before change in meds? Thank you.
