How to sleep on a wedge pillow for acid reflux?

Acid reflux, often referred to as gastroesophageal reflux disease (GERD), is a condition wherein stomach acid frequently flows back into the esophagus. This backflow can irritate the lining of the esophagus, causing heartburn, regurgitation, and other discomforts.

One popular method for alleviating the symptoms of acid reflux, especially at night, is to use a wedge pillow. This specially designed pillow elevates the upper body, helping to prevent the flow of acid into the esophagus and facilitating better sleep. Sleeping with a wedge pillow can take a bit of getting used to, but with the right guidance, it becomes a comfortable and effective solution.

How do pillows for acid reflux and GERD work?

Pillows for acid reflux and GERD (Gastroesophageal Reflux Disease) are specially designed to help reduce the symptoms and discomfort associated with these conditions, particularly during sleep. Their mechanism of action is rooted in simple anatomy and gravity. Here’s how they work:

  1. Elevation:
    • When you’re lying flat, stomach acid can easily flow back into the esophagus, especially if the lower esophageal sphincter (LES) — a muscle that acts as a valve between the esophagus and stomach — is weak or relaxed.
    • Pillows for acid reflux and GERD elevate the head and upper body, creating a gentle incline. This position makes it more challenging for stomach acid to travel up the esophagus.
  2. Gravity Assistance:
    • By elevating the head and upper body, gravity helps in keeping stomach contents, including acid, from refluxing into the esophagus. The angle reduces the likelihood of acid moving up, especially while sleeping.
  3. Reduction in Esophageal Exposure:
    • Elevated positioning not only prevents new acid from entering the esophagus but also helps drain any acid already present back into the stomach quicker, reducing the duration of esophageal exposure to stomach acid.
  4. Prevention of Full Esophageal Relaxation:
    • Studies suggest that sleeping on an incline might prevent full relaxation of the LES, further reducing the chance of acid reflux.
  5. Pressure Redistribution:
    • Pillows designed for GERD may also help in redistributing pressure, ensuring there’s less pressure on the stomach. When there’s excessive abdominal pressure, it can push stomach contents into the esophagus.
  6. Enhanced Breathing:
    • The inclined position might also enhance breathing, which can be beneficial for individuals with conditions like sleep apnea, often linked with GERD.


  • Degree of Incline: The degree of elevation matters. Typically, an incline of 6 to 8 inches is recommended, though individual needs might vary.
  • Full-length Wedge Pillows: Some people prefer wedge pillows that support the entire torso instead of just the head and neck. This design can prevent sliding down the pillow and ensure a consistent angle throughout the night.
  • Alternative Solutions: Adjustable beds or mattress risers can achieve a similar effect, offering an inclined sleeping surface.

While pillows and elevation methods can provide symptomatic relief, they are just one part of a comprehensive approach to managing acid reflux and GERD. Lifestyle changes, dietary adjustments, and medications (as prescribed) also play critical roles in managing these conditions. It’s essential to consult with a healthcare professional to create an effective and personalized treatment plan.

A Detailed Guide on How to Sleep with a Wedge Pillow for Acid Reflux

  1. Choosing the Right Wedge Pillow:
    • Material: Opt for a high-density memory foam pillow, which offers both comfort and durability.
    • Incline: The elevation should be between 6 to 8 inches. A steeper incline might be uncomfortable, while a shallower one might not be as effective.
    • Size: Ensure the pillow is wide and long enough to support your upper body without causing you to slide off.
  2. Positioning the Pillow:
    • Place the wedge on top of your mattress with the higher end against the headboard or wall.
    • Ensure it’s centered so you don’t roll off during the night.
  3. Getting into Position:
    • Sit on the bed with your lower back pressed against the lower end of the wedge.
    • Gently lay back onto the pillow, letting your torso be elevated and your head rest comfortably at the top.
    • Your neck should be in line with your spine to prevent any strain.
  4. Leg Positioning:
    • You can keep your legs straight or bend them at the knees, whichever feels more comfortable.
    • If you need added support, consider placing a pillow under your knees.
  5. Combining with Other Pillows:
    • If the wedge pillow’s elevation isn’t enough for your neck, you can place a regular pillow on top of the wedge pillow for added height and support.
  6. Sleeping Position:
    • While the back (supine) position is the most common for those using wedge pillows, side sleeping can also be effective. If you’re a side sleeper, ensure your neck is aligned with your spine and not tilted.
  7. Additional Tips:
    • Start with short durations: If it’s your first time using a wedge pillow, consider taking naps or resting for short periods before sleeping an entire night on it. This helps your body adjust.
    • Protect your back: If you feel strain on your lower back, consider adjusting your position or using an additional pillow for support.
    • Wear loose-fitting pajamas to ensure unrestricted circulation.
    • Keep other acid reflux remedies in mind: Apart from the wedge pillow, maintain a diet that reduces acid reflux triggers, avoid eating right before bed, and consider medication if prescribed by a doctor.
  8. Maintenance:
    • Like any other pillow, keep your wedge pillow clean. Use a removable cover that can be easily washed. Ensure the pillow material is spot-cleaned as per manufacturer’s instructions.

Who should try an acid reflux pillow?

An acid reflux pillow, often referred to as a wedge pillow, is designed to alleviate the symptoms of acid reflux or gastroesophageal reflux disease (GERD). Here’s a list of individuals who might benefit from using an acid reflux pillow:

People with GERD or Chronic Acid Reflux:

These are the primary individuals who can benefit. Frequent heartburn, regurgitation, and an acidic taste in the mouth are common symptoms.

Occasional Acid Reflux Sufferers:

Even those who experience acid reflux occasionally, especially after certain meals or behaviors (like overeating or consuming spicy food), might find relief using a wedge pillow during nights when symptoms are worse.

Pregnant Women:

During pregnancy, many women experience acid reflux or heartburn due to the growing fetus putting pressure on the stomach. A wedge pillow can provide temporary relief, especially in the latter stages of pregnancy.

People with Sleep Apnea:

While a wedge pillow is not a primary treatment for sleep apnea, some individuals with this condition also have GERD. The elevated position can improve breathing and reduce acid reflux simultaneously.

Individuals with Hiatal Hernia:

A hiatal hernia occurs when a part of the stomach bulges through the diaphragm into the chest. This can cause acid to leak into the esophagus. Elevation during sleep might provide symptom relief for these individuals.

Post-Operative Patients:

After certain types of abdominal or chest surgeries, lying flat can be uncomfortable, and there might be a temporary increased risk of acid reflux. A wedge pillow can help during the recovery phase.

People with Chronic Cough or Asthma:

In some cases, a chronic cough or worsening asthma symptoms at night might be related to undiagnosed GERD. Elevating the head during sleep might provide relief, although it’s essential to address the primary condition with a healthcare professional.

Laryngopharyngeal Reflux (LPR) Sufferers:

LPR, often called silent reflux, is when stomach acid reaches the throat or larynx. Individuals might not experience traditional heartburn but can have symptoms like a chronic cough, sore throat, or hoarseness. A wedge pillow can be beneficial for them.

Individuals with Night-time Aspiration:

In severe cases of GERD, there’s a risk of aspirating, or breathing in, stomach contents into the lungs. This can lead to coughing, bronchitis, or pneumonia. Elevating the head and upper body during sleep can reduce this risk.

While many people can benefit from an acid reflux pillow, it’s essential to consult with a healthcare professional before making any changes to your treatment routine. The pillow is an adjunctive therapy and should be used in combination with other advised treatments and lifestyle modifications.
