Welcome Tw1nset but sorry you've had to join us too 
I've got bowel cancer.
What surgery are you having? The thing about bowel surgery is that your bowel still has to do its job even while it's recovering, so you have the double whammy of surgical recovery and also a bowel that's going a bit haywire. Though it sounds like you're already getting that experience!
I'm recovering at the mo from a relatively minor op, just to deal with some issues I had following previous surgery.
I'd add to the hospital packing list a small cushion/pillow to hold against your abdomen for support when you move, cough, sneeze etc. (If you suffer from hayfever, dose up on tablets because you do not want to be sneezing if you can avoid it
) also make sure you have knickers and pyjama trousers that won't rub on the incision. I wore nighties and pyjama trousers in hospital to give me a bit more coverage.
When I had my previous surgeries the hospital dietitian came to see me afterwards so that may already be lined up for afterwards.
I refused to drink the special drinks as I hated them. This time they agreed not to give me any!
Re nutrients I have found the same. I guess carbs are the easiest to extract so we can get those even when our bowels are working quite inefficiently, whereas all the more useful nutrients are more likely to pass through.
Halfbaked sorry you've been so unwell again. Are you on tax? Others have had nail problems on that especially. I think it is helped by using dark nail polish, but I don't know if it's too late by the time they're showing damage. I hope the reflexology helps :) I'm sure she's seen mankier feet! Mine have been really dry and cracked. The best foot cream I've found is Soap and Glory Heel Genius.
Fresta I'm really sorry about your MIL's diagnosis. Fingers crossed she won't need chemo 
Anna I hope you managed to have a lovely time with your family yesterday. I hope you get a scan appointment soon hopefully with reassuring results
and I hope you get some relief from the pain too
I hope everyone had a good Easter. Sending good wishes to all the posters who have gone quiet recently. I hope you're all getting on OK
