ACID REFLUX – HOW DOES IT HAPPEN?
Acid reflux occurs when stomach contents flow back into the esophagus, causing heartburn, throat burning and discomfort.
The stomach has two important “doors”:
🔹 Cardiac sphincter – helps prevent acid from flowing upward.
🔹 Pyloric sphincter – controls the flow of stomach contents downward.
When these muscles don't work properly, pressure can push stomach acid back up into the esophagus, causing acid reflux.
