Lots of support out there

I have been wandering round the net looking for help and support so I can get some ideas as to what to expect over the next few months. My brother in law who lives in Adelaide found a crohns & colitis support site in Australia that has been very good, Crohns Disease and Colitis Support Group Australia and from there I found a fantastic ostomy help site, Ostomates.org. A light-hearted site but with a lot of extremely helpful & friendly people who have been through what I am about to go through and so they can explain things from a different perspective to the medical profession. I have got a lot of questions for the nurse when I see her on Friday 27th, just seen the date and that is tomorrow.
One of my questions was about my weight. I have put on a lot of weight due to not doing much and the fact that I have been on steroids for 6 months. One side effect of them is weight gain, basically I can't stop eating. So, eat lots + stay at home = 16kg increase in weight. This is the gain since I was going to the gym last summer, I lost a lot of weight due to the illness in the autumn so I guess I have actually put on around 25kg in all. I need to lose at least 17kg to get back to some kind of healthy weight, not going to get this off before the op though cos I can't get out on my bike or on long walks till after the op, a sort of chicken and the egg dilemma. The question was about how does the stoma react to weight loss.The main problem seems to be that the stoma should not change much but as you get thinner the shape of your stomach changes, pretty obvious really I suppose, so you have to go careful that you don't get leaks.
That is it for now, I will get some more stuff down before my appointment with the nurse I expect, will definitely post the after the appointment.
