While I disagree with your assertions, if you are the type of person who prefers to live the rest of your life with, say, Crohn's, and be able to still push hard and perform well at the gym, by all means do that. If you're willing to set a side of period of a couple months to heal your body, research more.
It's actually interesting how many people I meet at the gym that from the outside appear very fit and healthy, only to find out they're actually pretty ill, from IBS and other gut issues, thyroid problems, etc. The gym is actually masking many diseases for people because physically they appear healthy.
