Dr. Sarno himself suffered from recurring GERD aka heartburn. Here is what he said about it in his book
Healing Back Pain on page 45.
“Heartburn means that I’m angry about something and don’t know it. So I think about what might be causing the condition, and when I come up with the answer the heartburn disappears. It is remarkable how well buried their anger usually is. Generally for me it is something about which I am annoyed but have no idea how much it has angered me. Sometimes it is something so loaded emotionally, I don’t come up with the answer for a long time.”
Fifteen years later in his book
The Divided Mind at pages 125-26, Sarno reported going on a long trip with his wife and suffering from GERD the whole time. He wrote: “She and I both recognized this to be psychosomatic, and we tried to figure out what was making me unconsciously angry.” They came up with several possibilities: He disliked the inconvenience and discomfort of traveling; he did not like the places they were visiting; the trip was too long; he would rather be at home working on a book. But, as he put it, “We obviously didn’t hit on the right answer, because my symptoms continued unabated for the entire trip.” He continued:
“It wasn’t until we got home that I realized what had been going on. I had promised the long trip to my wife, who loves to travel. I was being a good guy. I was unconsciously furious for having to do something I really didn’t want to do. My psyche wouldn’t permit me to be consciously furious at my wife, and neither would my reasonable self—so to be absolutely sure the rage remained unconscious, the brain dished up the severe gastrointestinal symptoms. The rage, of course, was the reaction of that unconscious child-primitive—selfish, narcissistic, and totally unconcerned with the needs and desires of anyone else. Not very flattering.”
Sarno was referring to what Freud called the id. What Sarno said next was shocking:
“Earlier in this chapter I suggested that reasonable people might prefer to deal with the unconscious rage rather than the pain and discomfort of a psychosomatic symptom, if the brain’s decision maker would only give them the opportunity to choose. My gastroesophageal reflux episode prompts me to rethink my position. Rage at my wife would have been inappropriate and unfair—better to suffer gastroesophageal reflux.” (I added the italics.)
Draw your own conclusion. Mine is that Sarno was too in the thrall of Freud.
