There is currently no cure for Irritable Bowel Syndrome (I.B.S.) and it is not actually an illness, just a set of symptoms that doctors are unable to define in any other way. The pain is caused when the muscles from the throat to the stomach get out of sync. When working properly they automatically propel food down towards the stomach, rather like a Mexican Wave, which is why you can still eat and drink if you are hanging upside down.
Although as previously stated there is no cure, the relaxation techniques that are taught can sometimes work so well that it feels like a cure. You will need a minimum of three sessions and a maximum of nine.
