Cheeky you can do some research on line to get the information you are seeking.
This site really does not allow us to give medical information.
Or ask your own doctor or his nurse as they can fill you in much better than we are allowed to here.
I am sure that your mom is sick, based on what you have reported previously about her drinking. Some of it can be from her drinking, some from her poor diet (not eating just drinking) and some from a compromised immune system from the not eating and the drinking.
Best to get complete and accurate information from your own doctor.
