Thanks for posting this. Hopefully people are getting the idea that acid could be the culprit. Might not be everyone's issue but it was mine. I'd start there since it's the least invasive. In addition to buffering acid, calcium tightens the LES. If you don't have a lot of calcium in your diet, have heartburn and shortness of breath, it could point to a weakened LES as evidenced by @merpreb 's video and calcium might be of benefit to you.

If your shortness of breath is caused by acid reflux you want to address that quickly. Some people have silent reflux (I used to) without heartburn. It was found during a scope of my esophagus. Long term reflux can damage the esophageal lining and in rare cases leads to Barrett's esophagus which is not good.

I know it seems too simple that mineral deficiencies can cause some of this but as someone who's lived the nightmare... went to a bunch of docs who couldn't help me, to sleeping propped up on pillows from heartburn, from unexplained weight loss despite eating (you could see my bones), hair fall, anxiety, insomnia, silent reflux and constant sore throat, violent spells of vomiting, episodes of not being able to swallow, depression and the list goes on...every one of those things resolved or improved greatly with a change in diet and minerals...mainly magnesium for me, but small amounts of calcium and most recently potassium (be careful with this mineral if you supplement--food is best) and controlling my acidity levels...again with diet, stress management, sleep and adequate amounts of water.

Our world conditions us that docs, prescriptions and surgery are the answer to everything and while it is the answer for some, don't underestimate the power of the body to heal itself if given what it needs.

Be determined to find an answer. I'm in my early 50's. I lost years of my life dealing with that stuff. Time I can't get back.
