From a baby to a child to a teenager to an adult my symptoms improved. I believe my tolerance increased as I got older. I do still 100% have the condition just the symptoms are slightly lesser than as a child. This is possibly partly down to awareness/better food decisions.
I will have this condition for life. It is an inconvenience, but it does not rule my life, I still do all the things I want to, I am a fit, active and healthy person. Wether later in life I will experience bowel problems due to my symptoms over the years, only time will tell.
