Well... try not to worry. Worrying won't do a thing for Grace's Crohn's.. but it will make you sick in the end... and it will worry Grace more than it needs to.
I was diagnosed when I was 18 (i'm 40 now) but it started way earlier than that... i was going to the bathroom between 20 and 80 times a day... ridiculous.!!!
I only went to the doctor when I bled once... i got scared.
I immediately went on a boiled chicken and white rice diet... that's it... i ate nothing else and only drank water... for an entire year... no joke! i didn't stray for a minute.. no juices no milk, nothing... no ice cream no cake no chips..lol literally just water rice and boiled chicken...
It was the best thing I ever did!!! It must have given my intestine time to heal itself, because I have had only a mild case of Crohn's since then... Occasional bouts of stress, or poor eating (red sauces, milk etc..) will give me a day or two of diarrhea... but other than that... normal...
the meds did nothing for me... and since trying meds for 6 months when i was 18... i've never been on meds...
so stick to a very bland diet.. let her intestine heal itself... and hopefully she will only ever have a mild case of it when she grows up!
