Mr. Dai, 74, experienced swallowing difficulty and reflux because his lower esophageal sphincter did not relax sufficiently during swallowing, causing food to accumulate in his esophagus.
Recently, I often experience heartburn and a burning sensation in my throat, especially when I am tired or stressed. Is stress a cause of gastroesophageal reflux disease? (Mai Thanh An, 37, Hanoi)
