Hi,
IBS is not a disease, it is a convenient label given when no other diagnosis fits. I would think it is not the IBS they seek to treat but in fact your symptoms they are trying to manage for you. At least they are trying to help, many of us get left in the too hard bin and are eventually left to our own devices.
There are some dietary restrictions for SBS and I would think that liquified food might help the absorption. The best plan is to do your own research and see what might work for you. My Gastro specialists is still treating me for IBS despite it now involving ANS and they have run out of options. I was pleased to be told I was one of his few clients that got off my butt and tried anything and everything I could to help my situation. Essentially that is what it comes down to, self help in conjunction with the experts. I often ask about various different treatments and remedies to get the Doc's opinion on. Sometimes we are at odds but I usually try anything that sounds like it is a possibility and report back my findings. It gives the Doc a better understanding of what I'm trying, sometimes it is news to him sometimes I get a rye smile. But at the end of the day I can't just sit and wait for a cure that isn't coming anytime soon.
Cheers
