I am at a complete loss

My sister is in the hospital again. They are putting in a feeding tube. it will attach to the small intestine and bypass the stomach. This should be temporary (hopefully). She hasn't been well since her stone removal surgery last month. She went in perfectly healthy and came out sick and on a picc line. I feel so horrible for her. She has been through so much and it doesn't look like she is going to be getting relief anytime soon. I wish there was a cure for this condition.
