That's why simply changing sides may not solve the problem for everyone.

However, it can be a useful part of a broader approach.

The Timing of Your Last Meal Matters

One of the simplest strategies for reducing nighttime reflux is to avoid going to bed immediately after eating.

When you eat a large meal and then lie down soon afterward, your stomach is still relatively full.

There is less time for digestion to occur before gravity stops helping keep stomach contents down.

For people who experience nighttime reflux, allowing several hours between a substantial meal and bedtime may help.

The exact timing that works best can vary between individuals.

If you regularly experience reflux at night, paying attention to the relationship between dinner and bedtime can be surprisingly useful.

Try Elevating the Upper Body

Changing sleeping position isn't the only option.

For people with frequent nighttime GERD symptoms, elevating the upper portion of the body can sometimes help.

This is different from simply adding several pillows under your head.

Using a properly designed wedge or raising the head of the bed can create a gradual incline from the torso upward.

The goal is to use gravity to make it more difficult for stomach contents to travel into the esophagus.

However, comfort matters.

A sleeping arrangement that causes neck, back, or hip pain isn't necessarily a good solution.

What About Sleeping on Your Back?

Sleeping on the back can be comfortable for many people, but it may not be ideal for someone with significant nighttime reflux.

When lying flat, stomach contents can potentially move toward the esophagus more easily than when the upper body is elevated.

Some people therefore notice more reflux symptoms when sleeping completely flat.

Again, this varies considerably.

There isn't one sleeping position that is universally perfect for every person.

Should You Stop Sleeping on Your Right Side?

Not necessarily.

If you're healthy, comfortable, and sleeping well, there is no need to become frightened because you prefer the right side.

The strongest practical reason to experiment with left-side sleeping is if you experience reflux symptoms, particularly at night.

You can try sleeping on your left side for several nights and observe whether you notice a difference.

Pay attention to:

How often you wake up.

Whether you experience heartburn.

Whether you taste acid or food in your mouth.

Whether you experience coughing or throat irritation at night.

Whether your sleep feels more comfortable.
