The answer to that question is very complicated because there are a lot of variables involved.
I think that a lot of people can be in remission from flare ups with their IBS for years.
Flare ups can still occur if there is stress or if one eats the wrong foods again or the body decides it’s going to be allergic to something different then what was already on your food allergy list.
Other factors like hormone imbalance can sometimes bring on flare ups as well.
The point is to learn to enjoy where you are at in the moment that you have it. Whether it’s a good day or a bad day. Even if the flare ups are bad it will still help to see it as a blessing to make it through the day.
On my bad days I forgive myself for not being able to do everything and just know that I it alright.
Because it is alright to rest and recoup.
