Acid reflux is one of the most common digestive condition that creates a burning sensation in the chest, often called heartburn. While many people associate acid reflux with symptoms like indigestion, sour taste in mouth and bloating, most are surprised to know that it can sometimes be linked with back pain also. This often results in an important question: Can indigestion cause backache.
The answer is yes – even though not directly in all cases. Knowing about the connection between acid reflux and back pain can assist in recognizing the core reason and make sure one gets proper treatment.
What Is Acid Reflux?
When the stomach acid flows back into the esophagus – a tube carrying food from mouth to stomach, then acid reflux occurs. The primary cause behind this is weakening of the lower esophageal sphincter, a ring of muscle acting like a valve. Sometimes this sphincter also relaxes at wrong time.
Some of the common symptoms of acid reflux are:
- Heartburn
- Indigestion
- Bloating
- Chest discomfort
- Difficult swallowing
- Sour or bitter taste in the mouth
- Vomiting
How acid reflux causes back pain?

Even if acid reflux mainly affects the digestive tract, the discomfort sometimes radiates to other parts of the body, which includes upper back and between the shoulder blades.
Referred pain
The nerves serving the esophagus and upper digestive system are connected to areas of the chest and back. When esophagus is irritated by stomach acid, the brain might start interpreting the pain as originating from back. This phenomenon is called referred pain. Often people referred this discomfort as:
- A mild ache between the shoulder blades
- Burning pain in the upper back
- Tightness around the chest and back
Muscles tension
Consistent acid reflux makes people to change their posture instinctively for reliving discomfort. Over time muscle tension and bad posture can result in pain in the neck, upper back and shoulders.
Hiatal Hernia
When part of the stomach pushes through the diaphragm into the chest cavity, hiatal hernia happens. This condition causes acid reflux and might also cause chest pain, along with upper abdominal pain and discomfort that radiates into the back.
When is back pain not because of acid reflux?
Not all back pain are related with indigestion is caused because of acid reflux. Other digestive conditions can also trigger pain that radiates to the back. Some of them are:
- Gallstones
- Pancreatitis
- Stomach ulcers
- Gastritis
In addition, the back pain can also result from musculoskeletal problems like poor posture, muscle strain or spinal issues. Therefore, it is vital not to think that acid reflux is always the cause.
Warning signs that requires medical attention
While heartburn occasionally is usually harmless, some symptoms needs timely medical evaluation. They are:
- Severe chest pain
- Sudden or intense upper back pain
- Issue in swallowing
- Unexplained weight loss
- Vomiting blood
- Black color or tarry stools
- Symptoms persisting in spite of treatment
As because heart related conditions can cause symptoms same as acid reflux, therefore any kind of severe chest or upper back pain must be assessed by a healthcare professional.
How to manage acid reflux and associated back pain?
Some lifestyle changes can substantially decrease acid reflux symptoms and the discomfort in association with that.
Helpful tips:
- Eat small but frequent meals
- Prevent spicy, acidic and fatty foods
