I wish there was a direct yes or no type of answer for you on this.....heck I wish there was one for myself that way we would know what to prepare ourselves for.
Unfortunately there is no answer that could satisfy your specific question beyond this:
How crohn's affects patients is different from person to person. There is no one-size-fits-all and thus there is no real way to tell when or if it will get better. Some people are born with it and live a life with few or no symptoms. Others develop it as adults and within the first few weeks of having it get unexplained complications that put them in the hospital for surgeries to remove all or part of the digestive tract. Some people have a hard time getting it under control with medication and/or diet and exercise. Others successfully get it under control the first time around. remission can be weeks, months or years at a time.
I think it is more important to focus on understanding your own body and how your Crohn's is affecting you overall. It will help you to make choices that are in your best interest for encouraging remission.
And you have a better chance of a life without flaring/complications and a chance at remission and living a life where you may not even notice you have Crohn's if you follow your treatment plan, practice a healthy lifestyle of proper foods and exercise, reduce the amount of stress in your life and keep your follow-up appointments.
