If possible post in details medical history of your mom,I shall revert with answers after seeing it,you should continue Shri Maha Mrityunjay japa and it will surely help your mom.While seeing your post I can say that her HB is lower and blood urea is higher due to kidney mal functions,go ahead and meet good eurologist he may advise dialysis,do it and after couple of week her kidney may start function normal again.I underline that you must consult specialist and act on his advises.
