With all these normal daily activities that would trigger regurgitation, the esophagus seems to be highly exposed to reflux?
Actually the esophagus has many defenses against acid reflux and its consequences. Anatomical barriers in the form of muscles inside and outside(diaphragmatic) the wall of the esophagus enforce its lower sphincter to prevent reflux. Acid clearance from the lumen of the esophagus is mechanically assisted by gravity and its propulsive movement towards the stomach. Acid is chemically antagonized by saliva and the esophageal gland secretion.
The third mechanism against reflux is tissue resistance. It includes the bicarbonate content of the glandular secretions on the surface of the esophagus; the tight junctions between cells lining its lumen and the normal blood flow in the wall of the esophagus.
These defenses would be efficient only in cases of mild infrequent reflux.
What is acid reflux relief?
In medically oriented terms, antonyms of the word relief include pain, distress or damage. That links its meaning to both subjective and objective aspects. Subjective, denoting sensations experienced by the sufferer such as pain and objective, meaning physical findings detected by specialists which are either functional distress or organic damage. Actually relief is related to control measures and it quantitatively signifies removal of an unpleasant existence or reduction of its magnitude. The definition of relief, therefore encompasses alleviation of pain, relaxation of distress and healing of damage. Acid reflux on the other hand has two sides; the subjective side (symptoms) which reflects the symptom of heartburn and the objective side (signs) that reflects the functional and/or organic signs of esophageal changes. Acid reflux relief is therefore a broad term that covers all the measures used to control symptoms and signs of acid reflux disease. Normally, the lower esophageal sphincter remains closed except during swallowing. This prevents the passage of food and acid from the stomach into the esophagus. If the lower esophageal sphincter becomes weakened or relaxed, stomach acid may back up into the esophagus. Frequent acid reflux can irritate and inflame the lining of the esophagus, causing symptoms and signs of acid reflux. A better understanding of relief would thus entail knowledge of some aspects of normal structure and function, so that changes in the disease and its control could be easily considered. Actually acid reflux relief involves both preventive and curative measures, and in addition to treatment; orientation with the causes, symptoms and complications of acid reflux are essential for proper management. Acid reflux relief includes: dietary changes,lifestyle modifications, specific medications and surgical operations.Basic knowledge of the underlying causes and progression of acid reflux and answering frequently asked questions about its relief; add to the depth of understanding.
