I have reflux and are taking ppi for it i'm waiting to see a specialist with it i've got a inflamed food gullet when i shout it burns more why ?

Reflux: reflux will get worst with shouting specially if you are shouting with any kind of anger stress and anger could increase the amount of acid in you stomach even if you are taking medicine manage your stress minimize shouting avoid spicy and greasy food most likely the specialist will schedule a scope to know more about your problem good luck

Several reasons: Without an actual examination, I cannot give specific medical advice on your particular health, but increasing abdominal pressure will, of course, increase the reflux if food is there. Shouting increases reflux. Alternatively, shouting stresses the voice box, and if it is already irritated from the reflux it will get more irritated by the shouting added to reflux.

Abdominal pressure: When you shout, cough or sneeze it increases the pressure in your abdomen and can push stomach acid up into your esophagus and cause more burning.
