it sounds like u had a seven month flare... and why it stopped is hard to answer... problem is crohns could still be hurting you inside and you are not experiencing symptoms because i have seen others on here talking about
not having symptoms but the colonsocopies or other tests they have done show inflammation. i am not sure why u r not on meds and why u sufferred so long with symptoms seemingly untreated... but if it was a personal choice you may be a lucky one who is now in remission without any explanation. also i think hormones/reproductive issues (like maybe birth control pills) are linked to the whole crohns experience but this is something to discuss with a dr... do u have a regular gi that u see?
personally i have had two big flares in my life thus far- once 12 years ago i was sick and required a lot of medical attention for about
a year or 2. then this year i again began flaring. each flare meant a search for new meds and treatments to settle the disease. i was in remission for a long time on imuran and now i have added humira to the imuran with hopes of stopping this flare and going back into remission.
if u were not eating well and you were losing weight, and u were in pain, you should have been closely followed by your gi and meds etc should have been investigated. if crohns goes untreated u r at risk of other complications like scar tissue which can lead to blockages. your type of crohns doesn't seem mild if the eating/weight loss and pain were major issues for so long.
not sure if any of this helped but the bottom line is: crohns is chronic and incurable, there is no way to know what causes it to 'flare' or go into remission and most people need maintenance meds to keep them well and, even while in remission, i had regular blood work and med appts with my gi to ensure the crohns is still on track and behaving.
after 12 years of remission (all the while taking meds) i am back where i started but now instead of taking one med, i am taking two. i guess if this doesn't work, my next step is surgery to remove the scar tissue that is causing some trouble for me. for me that is my last resort so there is no way i will stop the meds if they make me well again.
good luck
