Health question regarding colon.

I have a female friend (about 45) who has had her gallbladder removed and also has had about 8 inches of her colon removed due to diverticulitis. She now told me that she has been diagnosed with "colon spasm" and she would like to know what she can do to revert her health problems with natural medicine. Would colonics be a good idea? How about the liver flush? Fasting? I would like to get advice as to what she can do to reverse her diseases given her aforementioned conditions. Thank you so very much. Tweet
