Acid reflux occurs when stomach acid travels back into a person’s esophagus, and frequent acid reflux can lead to gastroesophageal reflux disease (GERD). Cannabidiol (CBD) may help calm the soft muscle tissue within the gastrointestinal tract, although more research is necessary before scientists can confirm this.

When acid regularly travels back up into a person’s esophagus, the tube that connects the throat to the stomach, it can lead to GERD.

The most common cause of acid reflux is the digestion of acidic food, such as

  • chocolate
  • coffee
  • citrus fruits
  • spicy foods
  • peppermint

Specific medications can also result in acid reflux as a side effect.

CBD may have some positive effects on acid reflux, and this article will look at the current evidence in more detail.

Although they share close links, acid reflux and GERD are different. Acid reflux is the return of stomach acid into the esophagus. During acid reflux, a person may also experience heartburn. This usually occurs after eating a large meal or spicy and acidic foods. Drinking alcohol can also cause acid reflux.

Acid reflux can also occur sporadically, and dietary changes may help ease its symptoms.

However, if a person experiences these symptoms twice or more in a week, this can be a sign of GERD. Symptoms can include:

  • heartburn
  • acid reflux
  • difficulty swallowing
  • chest pain

An individual may also notice worsened symptoms when they lie down.

If a person suspects they may have GERD, they should speak with a doctor or healthcare professional. Prescription medications can help ease symptoms.

CBD is one of the many compounds of the Cannabis sativa (C. sativa) plant. According to a 2017 report by the World Health Organization (WHO), it does not create dependency in those using it.

Below are some helpful terms relating to CBD.

CBDA compound within the C. sativa plant that does not create the “high” sensation that individuals commonly associate with cannabis use.
Tetrahydrocannabinol (THC)A compound in the C. sativa plant. It is the psychoactive compound that creates a high sensation from cannabis use.
Full spectrumA full-spectrum product will contain all of the natural compounds in the cannabis plant, including THC. However, THC levels must be no more than 0.3% to comply with Food and Drug Administration (FDA) regulation on full-spectrum CBD products.
Broad spectrumBroad-spectrum products contain natural compounds of the cannabis plant. However, while manufacturers remove all or most of the THC in broad-spectrum CBD, it may still be present in trace amounts.
CBD isolateThis is the purest form of CBD and should contain 0% THC.
CannabinoidsThe compounds within the cannabis plant, of which there are over 120. CBD is the second richest compound in the plant after THC.
TerpenesAnother compound of the C. sativa plant, terpenes typically give plants their specific aromas. Some terpenes, such as limonene, may have specific health benefits.
Certificate of analysis (COA)Reputable manufacturers of CBD products should ensure a COA is available for inspection. These certificates provide information on the third-party testing that independent labs conduct on a particular product. Sometimes, products will have a scannable smartphone code that directs people to the COA online.

A 2017 review states a person’s endocannabinoid system, which reacts to CBD, has antisecretory effects on gastric acid. It also helps anti-inflammatory properties within the digestive system and could therefore relieve symptoms of GERD.

However, scientists need to conduct further studies on the effects of CBD on GERD to confirm these findings.

CBD can work with a person’s cannabinoid receptors, specifically within their gastrointestinal tract. One of the potential effects of CBD is calming the soft muscle tissue. This helps regulate muscle contraction and provide pain relief for heartburn.

In a 2018 report, the WHO found CBD does not have toxic effects on humans and concluded that it may complement the treatment of various medical conditions. Again, experts need to carry out further research to support this theory.

Here are some common questions and answers relating to CBD for GERD and acid reflux.

Are there other treatments for GERD besides CBD?

According to a 2018 report, the initial step for a person wanting to reduce symptoms of GERD is typically dietary modifications. However, the authors noted that studies looking at lifestyle and dietary changes for this condition are not robust.

They add that elevating the head is suitable for managing GERD, as it minimizes acid reflux in a person with GERD when lying down. It also recommends minimizing alcohol consumption, smoking, nighttime snacks, fatty meals, and large dinners.

Can CBD make acid reflux worse?

Although there are minimal studies on CBD’s effects on acid reflux, researchers believe it is not toxic to humans.

However, future investigations will help support this.

What should a person look for when choosing CBD for acid reflux?

Whether a person chooses CBD in capsule, oil, or spray form is a personal preference. They may also consider their budget, delivery times, and manufacturer authenticity. However, if an individual uses CBD to counter the effects of acid reflux, they should consider avoiding CBD featuring mint or citrus fruit flavors. This is because these flavorings are acidic and may exacerbate acid reflux symptoms.

Acid reflux occurs when a person’s stomach acid travels up the esophagus, typically following spicy or acidic foods or alcohol. If acid reflux occurs twice a week or more, this could indicate GERD. In these cases, a person can consider speaking with a doctor or healthcare professional.

Researchers believe CBD works with a person’s gastrointestinal receptors to ease the symptoms of acid reflux. It does this by helping control muscle contractions. It also helps anti-inflammatory properties within the digestive system and could therefore relieve symptoms of GERD. However, further studies are necessary to confirm this.
