Heartburn is often described as acidity and is commonly treated with antacids. However, gastro-oesophageal reflux disease (GERD) is more complex than occasional heartburn and should not be treated as simply a problem of excess stomach acid.
GERD occurs when stomach contents repeatedly flow back into the oesophagus because the body’s normal anti-reflux barrier is not functioning effectively. This can lead to symptoms such as a burning sensation in the chest, commonly known as heartburn.
Importantly, heartburn is a symptom rather than a diagnosis. People experiencing reflux can have different underlying conditions and may not show the same physical changes in the oesophagus.
Some people with GERD develop visible inflammation or injury to the oesophagus. Others can experience persistent reflux-related symptoms even when examinations do not show obvious damage.
A burning sensation can also be linked to increased sensitivity of the oesophagus or other digestive disorders. This means that experiencing heartburn does not automatically establish GERD, and the absence of visible inflammation does not necessarily mean that symptoms are insignificant.
Understanding this distinction can help people avoid assuming that every episode of heartburn is simply “acidity”. Occasional symptoms may have different causes, while frequent or persistent reflux symptoms may require medical assessment.
Doctors can evaluate symptoms and, when necessary, use appropriate tests to determine whether reflux, oesophageal sensitivity or another condition may be responsible. The distinction is important because treatment depends on the underlying cause rather than the symptom alone.
