Developed bile gastritis after gallbladder surgery over 7 months ago. Will it happen always now or can the body still adjust in future?

Body can adjust. The body can still adjust, but it is also quite possible that the two are unrelated, even though the timing is related. The analogy is some event on earth happening at the same time as a falling star. While the timing is together, there is no cause and effect relationship. Hope this helps!
