Assignment task: Explain the underlying pathophysiology that results in one (1) of the abnormal assessment findings in the context of the health challenge. (250 words) Pathophysiology of Heartburn Heartburn occurs when stomach acid moves up into the oesophagus due to an incompetent LES. The oesophagus is not equipped to handle the acidic environment, leading to irritation and a burning sensation. Normally, the LES remains closed except when swallowing, but in people with GORD, this barrier weakens, allowing acid to escape. This chronic exposure of the oesophageal lining to acid can cause inflammation and damage, leading to the characteristic burning discomfort of heartburn. Persistent reflux can eventually cause complications, such as oesophagitis, ulcers, or strictures in the oesophagus. Need Online Assistance?
