what was wrong with meredith grey in season 5 when she stayed utama from the hospital?

she gave her dad part o fher liver because he needed a transplant atau he would die. she did it for lexie. & because he was sober for like a bulan he didnt qualify for u.n.o.s.
because part of her liver was cut out and telah diberi to her dad, she needed bedrest (for a monthish) so while ellen was pregnant, meredith was stuck in a katil regrowing her liver.

But it was season 6, though
