Chronic aspiration is when a child repeatedly breathes in any food/drink, saliva, or undigested stomach contents that come back up the esophagus. These materials are known as foreign bodies, and the continual inhalation can cause several chronic (recurring) respiratory issues. It differs from acute (sudden) foreign body aspiration that can occur at irregular intervals.
If left untreated, chronic aspiration can be life threatening. It can also lead to:
Sleep apnea (temporarily stop breathing while sleeping)
Persistent wheezing or cough (lasting more than three weeks)
What are the causes of Pediatric Chronic Aspiration?
Several conditions can cause chronic aspiration, including:
Dysphagia – This disorder makes swallowing painful or impossible due to the muscles of the pharynx or esophagus not functioning properly.
Gastroesophageal reflux disease (GERD) – This digestive condition causes partially digested food or stomach acids to flow back into the esophagus (tube that connects the throat with the stomach).
Neurological disorders – Conditions like cerebral palsy can affect body movement, posture and muscle coordination, which can lead to a greater chance of aspiration.
Structural abnormalities – Anatomical irregularities can lead to a higher risk of aspiration. These include:
