Do you often encounter a burning sensation in your lower chest, especially after having your meal? This discomfort may be an indicator of a common gastrointestinal condition known as gastroesophageal reflux disease (GERD), better known as acid reflux.
Acid reflux is an extraordinarily widespread and regularly occurring ailment affecting countless individuals across the globe. But to identify the causes of acid reflux, we must first comprehend what it is.
The condition of acid reflux here occurs when the lower esophageal sphincter (LES)–the muscular valve where the esophagus joins the stomach–weakens or relaxes inappropriately, enabling stomach acid to flow back into the esophagus. This reflux of stomach acid irritates and injures the lining of the esophagus and can cause a fiery sensation known as 'heartburn.'
So, if you are questioning the causes of acid reflux, remember that the primary cause is the abnormal functioning of the LES. Though, there are also secondary sources that can exacerbate this problem.
Further causes are certain food and drink. Consuming hard-to-digest foods, fatty or greasy foods, spicy food, chocolate, caffeine, and alcoholic beverages could provoke acid reflux. Smoking is another critical contributor as it can hamper the operation of the LES.
Overeating or consuming excessive amounts at one time, especially before bedtime, can also cause acid reflux prominently. Moreover, obesity and pregnancy are also known to increase the risk of GERD.
Other potential causes can encompass certain medications, such as aspirin and specific 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, although the underlying cause of acid reflux is the dysfunction of the LES, there exist many secondary triggers that can exacerbate this issue. Being aware of these causes can significantly improve your ability to prevent and manage this potentially distressing condition.
