Hi Christian. I'm sorry that you've been diagnosed so young, but you sound like you have a good head on your shoulders (and you're restoring my faith in young people and their writing skills
).
Is your GI at a large hospital, one associated with a medical school? If not, you should see if you can go to one--they have much more experience there. The fact that your GI says that UC is diagnosed at 30-65 and didn't prescribe you a 5ASA (it works as an anti-inflammatory) worries me. UC, and Crohn's, are young people's diseases--most people are diagnosed in their late teens, 20's and 30's. Also, ask your GI about
going on a 5ASA. You shouldn't just be on Prednisone--it's a short-term solution; you should be taking rectal meds, Rowasa or Canasa, to decrease the inflammation in the beginning and need to be on an oral maintenance med as well, like Asacol or Lialda (which are all a part of the 5ASA drug category).
You've received good advice so far--don't stay on Prednisone too long, keep a food diary as diets vary from person to person. I wouldn't jump to iron infusions just yet. Like you, I had to get blood transfusions at the very beginning (I believe my hemoglobin level was around 4). After two blood transfusions and 3 months of oral iron supplementation, my hemoglobin went up to 11.
You and your parents should definitely talk with your guidance counselor. Let him/her know that you have a medical condition, you may have to miss school for illness or drs appointments, you may need to use the bathroom a lot, etc. Take a look at this website: http://www.nhlbi.nih.gov/health/public/lung/asthma/guidfam.pdf.
Also, take a look at ccfa.org. They have a ton of information and list of support groups.
