How common is (GERD)?
The population based studies have reported that one-third of western population experience the symptoms of GERD at least once a month, with 4-7% of the population experiencing daily symptoms.

Most patients with mild symptoms carry out self-medication, while those with more severe and persistent symptoms seek out medical attention.
