wedge pillow for acid reflux

Acid reflux, a condition where stomach acid flows back into the esophagus, can be a distressing experience for many. The burning sensation, discomfort, and potential damage to the esophagus have led many to seek effective solutions. One such remedy that has garnered attention is the use of a wedge pillow. In this article, we’ll delve into how a wedge pillow can alleviate the symptoms of acid reflux and give you the quality of sleep you desire.

What is Acid Reflux

Before we dive into the benefits of a wedge pillow, it’s essential to understand acid reflux. The esophagogastric junction (EGJ) acts as a valve allowing swallowed materials to enter the stomach and preventing acid reflux. When the muscles of the EGJ weaken or stiffen, it can result in irregular opening and closing patterns, leading to acid reflux and other esophageal disorder1.

The Role of a Wedge Pillow

A wedge pillow is designed to elevate the upper body, ensuring that the head and torso are raised above the waist. This incline can provide several benefits:

  1. Gravity Assistance: By elevating the upper body, gravity helps keep the stomach acid down, reducing the chances of it flowing back into the esophagus.
  2. Reduced Pressure: The incline can reduce the pressure on the EGJ, allowing it to function more effectively and prevent acid from escaping the stomach1.
  3. Improved Sleep: For many, acid reflux symptoms worsen at night. Using a wedge pillow can lead to a more restful sleep by minimizing nighttime reflux episodes.

Acid Reflux Research

A study titled “Pressure — area loop based phenotypic classification and mechanics of esophagogastric junction physiology” highlighted the importance of understanding the physics behind the opening and closing cycle of the EGJ. By gaining insights into its function, researchers can identify conditions that cause its degradation1. While this study doesn’t directly address wedge pillows, understanding the mechanics of the EGJ can help in appreciating the benefits of using such pillows.

Another study, “Comparing the Performance of Statistical Adjustment Methods By Recovering the Experimental Benchmark from the REFLUX Trial,” emphasized the significance of comparative effectiveness research based on observational studies2. Such research can provide insights into the benefits of various treatments, including the use of wedge pillows.

Perseverance is Key

While the benefits of using a wedge pillow are evident, it’s essential to note that sleeping on an incline can take some getting used to. It might feel unusual at first, and some might find it challenging to find a comfortable position. However, research has shown that perseverance is crucial. As with any change, the body needs time to adjust. Given the numerous benefits, it’s worth pushing through the initial discomfort (if any).

Choosing the Right Wedge Pillow

When selecting a wedge pillow, it’s crucial to consider its construction and materials:

  1. Memory Foam Layer: Wedge pillows are not made entirely of memory foam. If they are, then a very  hard memory foam is used, which is very uncomfortable. Instead, they often have a top layer of memory foam. The thickness of this memory foam layer significantly affects comfort and sleep quality. Generally, the more memory foam, the better. It conforms to the body, providing support and comfort.
  2. CertiPUR-US Certification: Ensure that the foam used in the wedge pillow is certified by CertiPUR-US. This certification guarantees that the foam is made without harmful chemicals and meets specific standards for performance, emissions, and durability.
  3. OEKO-Tex Certified Cover: The cover of the pillow should be certified by OEKO-Tex, ensuring it’s free from harmful substances and safe for use.

Beware of Marketing Tactics: Some wedge pillows do not contain any memory foam. Instead, they might use marketing terms like “therapeutic foam” or other fancy names. If it isn’t explicitly called memory foam, it isn’t memory foam. Pillows without memory foam tend to be harder and less comfortable.



Acid reflux can be a debilitating condition, but solutions like the wedge pillow offer hope. However, it’s essential to choose the right pillow to ensure maximum benefits. Look for pillows with a thick layer of memory foam, CertiPUR-US certification, and an OEKO-Tex certified cover. Avoid falling for marketing gimmicks and ensure you’re getting genuine memory foam for the best comfort.

Note: Always consult with a healthcare professional before making any changes to your sleeping habits or trying new treatments.
