Heart burn, chest pain, indigestion, or stomach acid coming up.
Our lower esophagus may dislike acid, but the back of our throat and even more our air passages, dislike it intensely.
Laryngopharyngeal reflux causes quite marked swelling in the throat.
Acid reflux and asthma are both common, and so will coexist frequently just by chance. There is however, more to it than that...
2/3rds of people with asthma have also symptoms of acid reflux, and nearly
the same proportion have a hiatal hernia.
The esophageal acid contact time*ˢᵉᵉ ᵇᵉˡᵒʷ is increased in 80% of people with asthma.
Of people with both conditions, more than half have erosions or ulceration in their esophagus.
Acid reflux into our air passages causes quite marked increase in asthma,
but it infrequently reaches the throat, let alone tipping into the air
However acid reflux can affect breathing even if only in the lower esophagus (but markedly more the higher it gets.)
If you have bad asthma, or are subject to any sort of attacks waking you from sleep, a test for acid reflux is worth considering. Attending to this problem may help your asthma.
Another intriguing possibility for relating chronic cough to stomach disorders via vitamin B12, has just recently been reported - see reference ⁸ below.
