Do you struggle to burp? You may be one of a not-so-small community of people with a condition known as retrograde cricopharyngeus dysfunction (R-CPD), also known as "no burp syndrome."

The condition was first described in 1987, although before 2019, only three individual case studies had ever been reported. It was only in 2019 that the condition received its official name, courtesy of Dr. Robert Bastian from the Bastian Voice Institute.
