If he doesn't believe in allopathy then he is neither intelligent nor logical.
On his place, with such consistently bad DNA and ALT, I myself would start the treatment right away irrespective of Fibroscan, in order to reduce future chances of HCC.
you need to check his fibroscan, hbsag quantity in iu/ml and if not over 7kpa he can:
keep monitoring but he must change food quality, take vit d3 10.000iu daily, take vit E 800iu daily and exercise to clear fatty liver
start pegintf or tenofovir, much better tenofovir
I see his dma and alat still rising during 5years wich Is So long.i had a flare wich at max during one year and my hepato was very careful about tho and if I start a treatment or not.i did blood tests sometimes each 15days then each 3monthes in addition ultrasound biopsy and fibro scan to evaluate ththe damage to liver and start treatment in appropriate time.thanks god I passed without treatment and no damage but five years without fibroscan or biopsy and rising alat.i think treatment is needed immediately because his body is doing nothing towards this replication.......
