Good luck with the infliximab Macca!
In response to earlier posts about diet and UC... UC manifests itself in too many different ways to say that there is one definitive bit of dietary advice. I tried lots of different diets / cut out lots of different foods and looking back, none of it made any difference.
My UC history:
2007-2010 - initial diagnosis, 3 hospital stays lasting 2 weeks+ each time, high doses of prednisolone, constant flaring. Tried lots of different diets and nothing worked. Ended up on azathioprine for 6 months but hated it. Mesalazine makes me worse.
2010-2018 - I went cold turkey on meds in 2010 and was pretty much flare free for most of the year. Lots of mild flares but nothing requiring and medication or hospitalisation.
2018-2020 - Each winter in 18/19 I had weird flares with fever, fatigue and urgency lasting 2-3 months. I got diagnosed with a parasitic infection called cryptosporidium in December 2019, spent a month in hospital and had my colon removed January 5th 2020.
I'm 5 months post surgery after having my colon removed and an ileostomy created due to uncontrollable UC and it genuinely has been one of the best decisions of my life. Its not until i removed the offending organ that I realised how much it affected me!
Life with a 'bag's is nowhere near as bad as in thought it would be. If you've already had UC / Crohns for a long time, you're pretty au fait with poo anyway so that side of things is easy. I do everything I did pre surgery and feel better doing it. Never having to worry about urgency and finding the nearest loo is liberating. Also no meds ever again.
It's been a blessing during corona quarantine. We've done a few longish drives for exercise in remote places. All public toilets have been closed and that would have been an instant no prior to surgery. Now I can just get on with life.
