What does acid reflux feel like?

Know the symptoms of this common condition including heartburn, regurgitation and irritation

Acid reflux overview

Acid reflux is estimated to affect up to 20 percent of Americans. It is when stomach acid reaches the food pipe or esophagus through the lower esophageal sphincter (LES). The LES is a ring of muscle at the end of the esophagus and is normally closed. It opens to allow food through into the stomach and then closes. If the LES muscle is weak or opens frequently it can cause stomach contents to back up into the esophagus.

Frequent acid reflux greater than twice a week, for which you have to take antacids on a daily basis, acid reflux that affects your life or has damaged the lining of the esophagus can indicate gastroesophageal reflux disease (GERD). This should be treated to avoid complications so it is important to consult your doctor.

Acid reflux symptoms

Symptoms will vary between individuals and depending on the frequency and extent of reflux. Symptoms can be mild or severe and include:

  • Heartburn - This is the most common symptom. The esophagus becomes irritated after stomach contents reach it, unlike the stomach the esophagus is not adapted to be in contact with gastric acid. This causes a burning sensation usually in the center of the chest under the breastbone but this can radiate. The sensation can be unpleasant to painful but the severity of this feeling does not necessarily mean lasting injury to the esophagus.
  • Sour taste in the mouth - This is caused by regurgitation when the stomach acid reaches the mouth. The taste can also be bitter and create a burning sensation. Long term dental problems such as erosion of the teeth and gum disease can arise with repeated exposure to stomach acid. Bad breath is also another symptom. 
  • Indigestion - This is a feeling of discomfort in the upper middle part of the stomach. You may feel bloated, full and nauseous. You may vomit or burp.
  • Sore throat - Stomach acid irritates the throat making swallowing problematic, causing a hoarse voice or an uncomfortable sensation that there is a lump in the throat. This may cause a dry cough. 
  • Asthma symptoms - Reflux can make asthma worse in children and adults if the stomach acid is able to irritate the airways. 
  • Reflux is often made worse by having a large meal that is rich in fat or spicy and bending down or lying down soon after eating. 

GERD complications

If GERD is not treated it can lead to serious complications through lasting damage to the esophagus:

  • Esophagitis - This is when the lining of the esophagus is inflamed. Irritation, bleeding and ulceration can occur. Esophagitis increases cancer risk.
  • Strictures - Scar tissues can lead to narrowing of the esophagus making it difficult to swallow food.
  • Barrett’s esophagus - The lining of the esophagus can undergo pre-cancerous changes or metaplasia. This makes the risk of developing cancers higher. 

Is it reflux or something else?

The symptoms of acid reflux and heart attacks are largely overlapping so can warrant a visit to the emergency department. You may suspect something more sinister than acid reflux if:

  • The ‘heartburn’ is worse than usual or different in nature
  • You have severe chest pain
  • You have a squeezing, tightening or crushing feeling in the chest
  • Other additional symptoms may indicate a heart attack such as:
  • Shortness of breath
  • Pain radiating to the left arm, shoulder, neck, jaw or back
  • Dizziness
  • Sweating
  • Nausea

Other conditions to be ruled out are pneumonia, chest wall pain or a pulmonary embolus. Another gastrointestinal cause may also be possible - some additional symptoms such as bloody or dark stools or black vomit may indicate that you have an ulcer that has bled such as a peptic ulcer. In this case call 911. 

Summary

Acid reflux is a common condition and the most common symptom is heartburn which is usually just an uncomfortable sensation. If acid reflux is frequent and affects your daily life there is a chance that you may have GERD. You should consult your doctor and get treated to avoid complications. Emergency conditions such as a heart attack may mimic acid reflux so it is important to get medical help if you suspect something is off.
