I want a colostomy, where do I start?

do you mean a colonoscopy? they can see what exactly is going on in your colon via camera but it can be dangerous and painful i had this problem when i was little and my gi doctor said i would die of colitis and im still alive i wouldnt go to extremes just yet have an upper gi done and also cut more fiber out of your diet this will help you have a little more control with movements
