Acid reflux is intimately common and widely experienced affecting a large number of people globally. But to identify the causes of acid reflux, we must first comprehend what it is.

The condition of acid reflux occurs when the lower esophageal sphincter (LES)–the muscle at the junction of the esophagus and stomach–loses its tightness, causing the stomach’s acid to flow back up into the esophagus. This reflux of stomach acid agitates and damages the lining of the esophagus and can result in a burning discomfort known as 'heartburn.'

So, if you are inquiring about the causes of acid reflux, remember that the primary cause is the abnormal functioning of the LES. But this condition can be aggravated by numerous additional factors.

Further causes are certain diet and beverages. Consuming hard-to-digest foods, fatty get more info or greasy meals, spicy foods, chocolate, caffeine, and alcohol can bring about an episode of acid reflux. Smoking is another key causal factor as it can hamper the operation of the LES.

Further potential triggers can encompass certain medications, like aspirin or some muscle relaxants. Stress can also impact the incidence of acid reflux, whilst not a direct cause, high levels of stress may stimulate behaviors that can trigger acid reflux.

In summary, the primary culprit behind acid reflux is an ill-functioning LES. However, many other factors can increase the severity and frequency of this condition. Being aware of these causes can significantly improve your ability to prevent and manage this potentially distressing condition.
