What is Gastro-Oesophageal Reflux?

The word reflux means to flow back or return; ‘gastro’ is a term related to the stomach; and ‘oesophageal’ relates to the oesophagus (food pipe). Following this, the term ‘gastro-oesophageal reflux’ is where stomach contents (comprising food and stomach acid) flow back into the oesophagus. This can commonly be seen with babies who posset following a feed, although it can be so much more than that. Gastro-oesophageal reflux can range in severity from being an occasional nuisance, to being severe and debilitating; it can also improve or worsen for a variety of reasons, with a child having good or bad days or weeks.

There can be a lot of confusion about gastro-oesophageal reflux, because the term is often used to describe the single event, the condition and the disease (Orenstein, 1992). The act of refluxing is the single event; it is a normal process that virtually everyone does at times. When a child refluxes more frequently, doctors may diagnose it as gastro-oesophageal reflux, the condition (GOR). When a child has complications as a result of their reflux, doctors may diagnose it as gastro-oesophageal reflux, the disease (i.e. gastro-oesophageal reflux disease/GORD).

It is important to remember not all vomiting or irritability is indicative of reflux, and families should seek a medical opinion to find the cause of their baby or child’s signs/symptoms.

RISA Inc supports families of babies and children who have been diagnosed with either gastro-oesophageal reflux or gastro-oesophageal reflux disease (families who do not have a diagnosis are encouraged to talk to their child’s doctor or child health nurse).

While awareness of reflux seems to be growing, many families still face community perceptions of reflux being a common or even trivial complaint that babies ‘get over’. While in most cases this is true, children can experience a wide range of symptoms, some quite severe, resulting in complications and occasionally surgery. Signs and symptoms of reflux, such as refusal to feed or prolonged bouts of screaming can be stressful and overwhelming.

Even when a baby or child is suffering from relatively uncomplicated reflux, families often need reassurance, and enjoy talking to someone who understands. For the families whose baby or child suffers complications as a result of their reflux, it is even more important that they can talk to other parents, and have the support and reassurance they need to get through this stressful experience.
