Is brain gut interaction a theory or an established fact? I have read that it is not known whether the dysfunction is in the brain, the gut or in the interaction.
Also, he seems to be saying that the "vicious cycle" can start at any point (stress, infection, sibo, nerve damage, other causes (?)) and once started, the cycle will complete, i.e. all other symptoms will come about. Is this a correct interpretation?
Cheers.
