You mention that your mother has been hospitalized more than once for
treatment of diveticulitis. I am assuming that she did not require any
surgical procedures such as drainage
or temporary colostomy
I know that we use a combination of drugs given intravenously while
in hospital to get the infection under control. If she also had a rupture
or perforation with abscess
then they may do drainage procedure.
If the infection is real bad , even after they take out that portion of
the large bowel , they may do a temporary colostomy. After 3-6 months
when all the infection is cleared , they can re-attach the bowel.
I don't think that was the case in your mother.
After any severe illness and after antibiotics , the appetite will be lost for
sometime. She needs to have good nourishment to build her immune system
working again. I suggest that you give her Probiotics which help to build up
good bacteria. A good yogurt without fruit (Flavor is O.K.) few times a day
would be helpful. Also, a good Super B-Complex Vitamin with C daily is good.
These will improve her appetite. If she is experiencing any diarrhea
in the stools , she needs to have stool tested for C.Difficile toxins which can
happen after antibiotic therapy.
She will improve with time and there is also the age factor that determines
the length of time for recovery.
I wish her the very best.
