Laryngeal reflux is defined as the reflux of gastric contents into the larynx and pharynx. Large amounts of data suggest an increasing prevalence of laryngeal symptoms in patients with gastroesophageal reflux disease. However, laryngeal reflux is a multifactorial syndrome and gastroesophageal reflux disease is not the only cause related to its pathogenesis.

Diet and lifestyle modifications are effective interventions for gastroesophageal reflux disease, although there is little robust published data. Diet and behavioural modifications are also found to be very effective in the management of laryngopharyngeal reflux, according to a treatment approach used in a UK district general hospital.
