Hello, ckouchis28, 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 bag. 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 or blood 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.
