Each time my mom's goes to the doctor's they try to draw her blood but can't all because she is dehydrated. I have tried everything to get her to drink different fluid but she only drinks small amounts. Now I am worried because she keeps getting UTI's plus she has a kidney stone which they have tried everything to remove it to no avail. So beside beets and spinach to build up her blood, what else can I use or do? It's heartbreaking.
