Crohnie1023, I agree with you, so many doctors are so quick to slap an IBS label on any type of gastro symptoms. I've heard that some doctors don't feel IBS is even a real thing, that everyone with significant gastro symptoms has something else "real" going on (things like IBD, food allergies, celiac, bacteria or parasite, etc). That theory definitely has some merit - certainly from the stories of every undiagnosed person I've read on the forum, most of them sound like much more than "just IBS" to me, but most of them have been told by at least one doctor that they've got IBS. That's so frustrating especially when it's clearly not IBS! It's a lazy catch-all "diagnosis" that most people just should not accept.
I seem to recall that you're diagnosed but your son is still undiagnosed, correct? Are his doctors trying to slap the IBS label on him and give him the brush-off, or are they still fighting to find the reason behind your son's symptoms? I'm just wondering if your son's struggles are the reason behind this IBS vent - if so, I'm sorry to hear it, I am undiagnosed myself and I know how frustrating it is to be given the IBS label.
