The Diaphragm and the Gatric Reflux

Updated: Mar 21, 2023


The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays an important role in breathing, as it contracts and flattens when we inhale, allowing the lungs to expand and fill with air. The diaphragm also helps to maintain the pressure gradient between the thoracic and abdominal cavities, which is important for proper digestive function.

The Gastroesophageal Reflux Disease (GERD) is a condition in which the lower esophageal sphincter (LES) - a ring of muscle at the bottom of the esophagus - does not function properly, allowing stomach contents to reflux back into the esophagus. This can cause symptoms such as heartburn, chest pain, regurgitation, and difficulty swallowing.

The diaphragm plays a role in preventing GERD by contributing to the pressure gradient that keeps the LES closed. When the diaphragm contracts during inhalation, it pulls the stomach downwards and helps to compress it, which increases the pressure in the stomach and the LES. This increased pressure helps to keep the LES closed and prevent reflux.

However, certain factors can weaken the diaphragm and contribute to GERD. For example, obesity, pregnancy, and smoking can all put pressure on the diaphragm and weaken its ability to compress the stomach. In addition, hiatal hernia - a condition in which the stomach protrudes through the diaphragm into the chest cavity - can also contribute to GERD by weakening the pressure gradient and allowing reflux to occur.

If you are experiencing symptoms of GERD, it is important to speak with a qualified healthcare professional for an accurate diagnosis and appropriate treatment.

How can osteopathy help Gastroesophageal Reflux Disease

As an osteopath, my approach to treating GERD (Gastroesophageal Reflux Disease) would be to address the underlying musculoskeletal imbalances that could be contributing to the condition. GERD occurs when the stomach contents, including acid, flow back into the esophagus, leading to heartburn, acid reflux, and other symptoms. One of the key factors that can contribute to GERD is a weakened or dysfunctional diaphragm.

As mentionned before, the diaphragm is a large, dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a crucial role in breathing, as it contracts and relaxes to help draw air into the lungs. However, it also has a close relationship with the stomach, as the esophagus passes through an opening in the diaphragm called the esophageal hiatus. If the diaphragm is weak or not functioning properly, it can allow stomach acid to escape into the esophagus, causing GERD symptoms.

To address this issue, the osteopath would start by conducting a thorough examination of the patient's posture, breathing patterns, and musculoskeletal system. This may involve palpation of the diaphragm to assess its tone, tension, and range of motion. I may also use techniques such as myofascial release, stretching, and breathing exercises to help release tension in the diaphragm and restore its proper function.

In addition to addressing the diaphragm, I would also look at other factors that could be contributing to the patient's GERD, such as dietary habits, stress levels, and medication use. By taking a holistic approach and addressing both the musculoskeletal and lifestyle factors that contribute to GERD, I believe that osteopathy can be an effective treatment option for patients with this condition.

The posture

When you sit at a desk for long periods of time, your posture can become slouched, which can lead to a lack of mobility in your spine. This lack of mobility can also affect the mobility of your diaphragm. If your diaphragm is not able to move freely, it can become tight and restricted, which can lead to breathing difficulties, such as shortness of breath.

Therefore, as an osteopath, it is important to assess and address any restrictions in the diaphragm mobility caused by a lack of mobility in the spine or prolonged sitting. Mobilization techniques can be used to help restore normal mobility to the diaphragm and improve breathing mechanics. Stretching and strengthening exercises can also be used to improve the flexibility and strength of the diaphragm and surrounding muscles. These interventions can help to alleviate symptoms of GERD and improve overall respiratory function.
