This field of medical hypnosis is so powerful!
I was referred a 12 year old girl with years of Fecal Retention Syndrome.
After having batteries of medical testing procedures, biofeedback and working with a psychologist she was told it was a "habit". The parents were besides themselves and finally gave me a call.
After the induction of hypnosis, we regressed to the first time of the bowel incident. She was 2 years old and standing behind the "big chair". Her daddy was in front of the chair. She felt her bowels starting to move and pushed them up. It felt "funny". They started to come down and she pushed them back up. It was a "funny" feeling. It felt different. She liked the "funny" feeling.
We had a talk with the little girl and then did some future pacing. The "habit" was gone.
Upon follow up, the habit is still gone and this little girl is very happy about it.
