LES closes tighter when in supine position than upright (!? counter-intuitive)
There is a difference between inspiration and expiraton.

Unfortunately, the study was done on healthy volunteers. I am looking for similar studies that determine which activities, which sleeping position or what food (if exists) would tighten LES.

I seem to feel better when I breathe while closing my mouth tight.
Perhaps sleeping in a special position, (with legs crossed for example) would tighten LES? if a solution to my night-time reflux is that simple.

How odd - they are saying the pressure is higher (and the LES tighter?) when recumbant as opposed to upright, and when fasting. Yet lying down or fasting seem to be triggers for many of us. Are we making ourselves worse by trying to stay upright?!

What would be the case if a person with GERD was in upright position 24/7? i know it's unrealistic because you need sleep but in theory? my guess is that no acid would enter esophagus right even if LES is partly open?

What is the mucus you get in the throat when you have been eating? i get this even if i stand up and eat, it can't be any possibility it can get up all way up there standing...

Is the mucus the protective layer by the body itself to clear the acid damage?

interesting study...amazing les pressure goes way up when subject takes a big breath and holds it with epiglottis open!

(diaphragm remains tense)

pressure drops at extreme exhale

so all we gerd sufferers have to do is hold our breath with lungs full of air for a couple hours...no problem

sheesh

Well maybe it does say something for breathing exercises though, MT?

Not sure their "significant" differences in pressure are actually that strong - 14 mm/Hg compared with 18 mm/Hg is small really and I think the power of gravity is far stronger!

Interesting study though . . . .

mmm

i think the pressure differentials are higher than that...if im reading it right (no guarantee)

This does validate my belief that deep breathing type exercises - pranayam yoga, sudarshan kriya yoga - etc. help reduce the reflux. Of course these don't offer a cure - but might help some.

MT,

Yes, the "significant" figures they quote for respiration are more "significant" than the figures they found for postural changes!

I'm thinking a normal LES HAS to work when lying down. There's not as much need to hold the stomach contents in while we are sitting up except right after eating. So it makes sense to me that it is tighter in supine (lying down on your back). But those of us here without normal LES function, who know what happens?

yes.... the study applies to normal people only. it's a pity they didn't repeat the same measurement on GERD patients.
