11 Furthermore, neurological impairments may predispose to the development of gastro-oesophageal reflux. Immaturity of the digestive system, hereditary factors and food sensitivities may also contribute to reflux in children. The former is responsible for approximately 50% of episodes of reflux in infants and children. 2 Abdominal straining (leading to increased intra-abdominal pressures) and delayed gastric emptying may exacerbate reflux. Transient relaxation of the sphincter is the major mechanism of reflux in infants, children and adults. Reflux occurs in children when intra-abdominal pressures exceed those across the lower oesophageal sphincter (LOS). 5 Likewise, GORD may exacerbate symptoms of asthma. Impaired salivation, for example due to Sjogren’s syndrome, anticholinergic medications or oral radiation therapy, may exacerbate the symptoms of GORD.
Some drugs (particularly anti-hypertensives, anti-angina medications, and NSAIDs). However, the evidence linking specific foods with GORD is lacking Eating large meals (especially late at night), or meals high in fat or chocolate. Predisposing factors with a higher risk of developing GORD include: 8-10 6,7Ī combination of genetic influences, lifestyle factors and dietary behaviour are thought to be involved in the development of GORD. 2 However, gastro-oesophageal reflux and gastro-oesophageal reflux disease are more common in infants than older children and adults due to both the immaturity of the oesophagus and stomach, as well as a higher fluid intake. This must be distinguished from physiological reflux – a benign and self-limiting condition common in infants during the first year of life. Gastro-oesophageal reflux disease can also present in infants and children. GORD is usually considered a disease of adults, with more than 50% of people with gastro-oesophageal reflux disease aged between 45 and 64. Furthermore, approximately 80% of the population will have experienced symptoms of heartburn at some point in their lives. 3 Similar high rates have also been demonstrated in Australia. Data from the United Kingdom and United States suggest that approximately 20% of the population will experience symptoms of heartburn and acid reflux at least once per week, and that these symptoms are a frequent reason for general practice appointments. 
Undiagnosed GERD can cause long-term complications that can lead to serious health problems so make an appointment today.Gastro-oesophageal reflux disease (GORD) is common in the Australian community. If you have several of the symptoms above, make an appointment with a gastroenterologist.
Ear ache - Ear aches and ear infections are not uncommon for GERD sufferers. Difficulty swallowing - A feeling of a lump in the throat that won’t go away could indicate inflammation of esophageal tissue and strictures. Bad breath - The acidity of reflux can cause bad breath. 
Excessive saliva - Extra saliva may be produced to wash acid from the esophagus. Nausea - Feeling queasy after a meal could also point to reflux. Chest pain - Heartburn or chest pain can be due to repeated acid reflux. Asthma - Wheezing and coughing can be caused by stomach acid reaching the lungs. In severe cases, acid reflux can cause choking. Bitter taste - A bitter or sour taste in your mouth after eating might be gastric acid from the stomach caused by GERD. Sore throat - GERD can also cause your throat to become sore after eating. Hoarse or husky voice - A deeper-sounding voice after a meal might mean that you are experiencing reflux of acid into the esophagus or throat. Here are some hidden symptoms of GERD that you might not recognize as being caused by reflux: However, a loose LES can allow gastric acid to backflow into the esophagus, and heartburn is only one of many symptoms. 
When functioning properly, the LES opens only to allow food and liquids to enter the stomach. GERD is caused by a weakness in the lower esophageal sphincter, the muscular valve that separates the stomach from the esophagus. Gastroesophageal reflux disease, or GERD, can have a variety of symptoms we do not typically associate with acid reflux. 10 GERD Symptoms Not Recognized by Most Acid Reflux Sufferers
