SUMMARY

The discussion centers on the interplay between mental and physical factors in controlling the gag reflex, particularly in the context of consuming unpleasant substances like vegetable smoothies. Participants highlight that while reflexes, including the gag reflex, originate from spinal cord responses, they can be influenced by conscious effort and repeated exposure. Personal experiences illustrate that psychological factors, such as past trauma from medical procedures like gastroscopy, can exacerbate the gag reflex, making it difficult to manage during dental treatments. The consensus is that overcoming the gag reflex requires practice and conscious intervention.

PREREQUISITES
  • Understanding of the human nervous system, particularly reflex arcs
  • Familiarity with psychological conditioning and its effects on physical responses
  • Knowledge of common medical procedures that may trigger gag reflexes, such as gastroscopy
  • Awareness of techniques for managing anxiety during medical treatments
NEXT STEPS
  • Research techniques for desensitization to reduce gag reflex sensitivity
  • Explore cognitive behavioral therapy (CBT) methods for managing anxiety related to medical procedures
  • Learn about the anatomy of the gag reflex and its neurological pathways
  • Investigate mindfulness practices to enhance control over involuntary reflexes
USEFUL FOR

This discussion is beneficial for medical professionals, psychologists, and individuals who experience heightened gag reflexes during medical or dental procedures, as well as those interested in the psychological aspects of physical reflexes.

I was trying to drink a vegetable smoothie, which I really don't like, and I vomited twice in the process. My friend drinks it without issue. What's the difference here?

My conscious mind really wants to drink the smoothie, but a few gulps in I feel an uncontrollable gagging.

I'm curious how much this is mental vs. physical, or whether it's completely intertwined.

Most reflexes can be overcome with practice, including the gag reflex though as I don't have a problem with mine I've never had to get over it. Reflexes aren't "mental" in the sense that they (by definition) do not involve the brain itself. They are a product of a stimulus to the spinal cord initiating a motor response back at the same time as sensory information is sent to the brain. Overcoming them requires repition with conscious action to preemt and stop the reflex.
 
I don’t suppose this is really a biological issue, I can only talk of my personal experience. Some years ago, because of acid reflux problems, I had the deeply unpleasant experience of undergoing a gastroscopy. The moment that thing touched my throat, it said, ‘I don’t know what that is, but get it the **** out of here’. The consultant kept telling me to just relax in increasingly impatient tones, but by the time it was over and I walked out, I looked as though I had been throttled. I trace my over-active gag reflex to that experience. Though everyone tells me that it is purely psychological, I find it impossible to fight. Now when I go for dental treatment, as soon as they start sticking various implements deep towards the back of my mouth, the urge to gag is over-powering and the more I fight it, the more the sense of panic grows. I did warn my dentist that I would be one of his more troublesome patients, and he takes it all very well, but it really is quite unpleasant for me.
