I often see clients who come with stress related issues.   I share the view along with Gabor Mate, that there is a very strong link between stress and disease.    Gabor worked in palliative care as an MD. and formed his viewed over a 20 year period.   By using simple hypnotherapy techniques to reduce stress, clients can see reduced susceptibility to disease.    I enjoyed his book immensely and have also included one of his talks to give you a flavour of how he formed his opinions.
