Is Acid Reflux Dangerous?, Symptoms & More

Acid reflux occurs when stomach acid flows back into the esophagus, the tube that connects the throat to the stomach. Normally, a ring-like muscle called the Lower Oesophageal Sphincter (LES) prevents the backflow of acid.

However, when the LES weakens or relaxes abnormally, acid can escape, leading to the symptoms of acid reflux.

Acid Reflux Common Symptoms:

  • Heartburn: A burning sensation in the chest or throat.
  • Regurgitation: Sour or bitter-tasting acid backs up into the throat.
  • Chest Pain: Discomfort or pain in the chest, sometimes mistaken for a heart attack.
  • Difficulty Swallowing: A feeling of a lump in the throat or difficulty swallowing.

Potential Risks of Untreated Acid Reflux:

While occasional acid reflux is normal, persistent and untreated symptoms can lead to more severe complications:

  • Esophagitis: Inflammation of the esophagus can occur due to prolonged exposure to stomach acid, leading to discomfort and potential damage.
  • Barrett’s Esophagus: Chronic acid reflux may result in changes to the lining of the esophagus, increasing the risk of developing Barrett’s esophagus—a condition associated with an increased risk of esophageal cancer.
  • Esophageal Stricture: Scar tissue can form in the esophagus, narrowing its diameter and causing difficulty swallowing.
  • Respiratory Issues: Aspiration of stomach acid into the lungs can lead to respiratory problems, including asthma, chronic cough, or pneumonia.
  • Dental Problems: Acid regurgitation can erode tooth enamel, leading to dental issues such as cavities.


We have discussed all the dangers that are associated with acid reflux. By understanding the nature of acid reflux, making lifestyle changes, and seeking appropriate medical guidance, individuals can effectively manage this digestive disorder and safeguard their overall health.
