I have really bad GERD, allergies and COPD. I have found that when my GERD is bad, my allergies are worse causing SOB & asthma. As well, the bloating from GERD compresses the lungs, making it difficult to breathe. As the stomach acid travels into the esophagus, irritates the airways, it causes the airways to restrict causing asthma/SOB.

MY COPD worsened considerably post-covid, but so did my GERD from the harsh medications which altered my gut biome. My SOB episodes now are mostly related to GERD and something I've eaten.

A relatively easy and harm-free fix is to take a good probiotic and alter your diet by avoiding trigger foods, eat smaller meals, and avoid processed and sugary foods.

I never associated my SOB with my gut, but knowing there is a relation and how to make it better has been a game changer for me! Best of luck!
