laryngopharyngeal reflux  Gastroesophageal reflux disease

laryngopharyngeal reflux  Gastroesophageal reflux disease (GERD) in children is a common physiological occurrence. Accurate epidemiological studies on the incidence and prevalence of GERD are lacking. Vandenplas and Sacre-Smits estimated that the incidence of reflux in all infants is around 18%. In some conditions, such as tracheoesophageal fistula, neurological impairment, or oral motor dysphagia, the incidence is thought to be as high as 70% . Infants are predisposed to reflux due to a shorter intra-abdominal esophagus and an immature lower esophageal sphincter. Older children have an increased risk of nocturnal reflux due to a reduced rate of swallowing. In addition, esophageal acid neutralization by the alkaline saliva is less at night in children than in adults. Up to 50% of normal infants have regurgitation, which in the majority of cases, spontaneously resolves by the age of 2 years. Reflux predominantly occurs during the postprandial period and typically presents as regurgitation or vomiting . (Burton DM,  et al ,2010)

These symptoms, however, tend to resolve after the first year of life . Persistent reflux may, however, give rise to complications. Pediatric laryngopharyngeal reflux (PLPR) is thought to be implicated in the development of various respiratory and otolaryngological conditions, including refractory asthma, recurrent bronchitis, laryngomalacia, and subglottic stenosis (SGS) . Recent studies, linking reflux with otitis media, have fueled a new theory for the pathogenesis of this common childhood disease . (Rozmanic V,et al ,2011)

so if you have persistent upper respiratory symptoms not responding to treatment

you should first consider  GERD as extra oesophageal reflux may lead or reach upper respiratory lead to laryngopharyngeal reflux .

and when you receive treatment for gerd you will get improved as the main cause of your symptoms is the extraoesophageal acid reflux reaching the upper respiratory and the main target of our treatment is to stop the cause

when to change your life style or to improve diet to act against gerd it will decrease the extra-esophageal symptoms or respiratory symptoms
