Hi,
No matter how many opinions the answer is always the same, IBS is undertermind, unknown and unseen therefore untreatable and uncurable. This is why those with IBS have different symptoms and will struggle to the end. Celiac's, chrons and gluten intolerance are all known diseases and treatable, they are not IBS. I have been poked, proded, metered, and breathalised along with every sample known taken and all I got was IBS and SIBO, methane producing. Unlike a lot of people I didn't seek just help. I actively participated in seeking a treatment and answers to which my gasto team are appreciative. I know exactly what I'm dealing with and all the permiables that go with IBS. I will continue to look for an answer, as one day someone may define what IBS is. Once it is known then what can be done will be a lot clearer as treating a known cause is possible, treating an unknown cause is not possible, it is just guess work with the fingers crossed.
Cheers
