Is gerd caused by low stomach acid or high stomach acid? i don't eat spicy/fried foods, no caffeine/nicotine, no cold drinks but still i'm suffering from 2 months with gerd. someone said les not close with low stomach acid and leads to gerd. guide me?

GERD is triggered when ANY STOMACH ACID is pushed back into the swallow tube by the normal squeezing/mixing action of the stomach. The lower the acid value the less likely it will irritate when it backwashes. The LES is a fold in the tube, not a valve. Its weakness can be a normal variant or aggravated by some foods & chemicals like caffeine & nicotine which keep it loose.
