G'day there. Welcome to the UC club.
Ok well, my advice is this, cuz I used to think as you do and it landed me in hospital. The body is intended to heal itself, the problem with UC is that the body can't heal itself faster then our immune system is damaging it. Thats why the meds are required.
Medication is pretty much a nescessity for UC, as diet (in nearly all cases) can not be used to get you back in remission as diet does not directly affect the UC, only the extent of the symptoms you experience.
You will probably find that things like soft drink, coffee, deep fried foods and red meat are all good triggers. At least they are for me, especially soft drinks!
Do not self medicate. It takes a very long time and a lot of trial and error to work out if the symptoms you are experiencing are from the medication, something you ate, a bug you've picked up or a flare of the UC itself. Especially with the medications, stopping it for a few days and then starting again usually exacibates the symptoms for me for about
3 to 14 days.
With regarad to medications, it can take a great deal of time and effort from you and your GI to find the best combination for you. Read on the net about
all the standard meds and understand how they all work. I don't "like" medication, but if I have to take it, I want to know what the hell its doing to me.
And my final bit of advice. NEVER, EVER let the UC get too far out of control. Thats the mistake I made and I have suffered nearly 2 years for that mistake. The longer you let UC go, the further out of control it gets, the harder it is to reign it back in.
Oh, and if you don't trust your GI - find another one.
This is just my take, but if you want to live the best quality of life you can, my advice is to do a lot of research on the net and understand what UC is and what its doing to you.
All the best
Disclaimer: This is not a "you have to do this", its just my view on UC and the lessons I've learnt the very hard way over the past few years. I was 16 when diagnosed initially and 27 now, so I've been at it a while hehe.
