How to Prevent Heartburn

Prilosec (omeprazole) may cause cancer, with some studies finding an association between this proton pump inhibitor (PPI) and an increased risk ofgastric (stomach) cancer.

PPIs are among the most commonly prescribed drugs in the United States.The emerging evidence from a number of studies implicates these medications when used over the long term to treat digestive disorders.

This article explains research to date on the link between PPIs and cancer, as well as alternatives to treatment with omeprazole.

PPIs like omeprazole, rabeprazole, lansoprazole, and esomeprazole are used to treathelicobacter pylori(H. pylori)infection,acid reflux, andgastroesophageal reflux disease (GERD).

When digesting food, the stomach uses gastric acid to break food down. During this process, cells in the stomach called G cells produce a hormone called gastrin, which signals to other cells to pump acid. PPIs stop acid from being produced.

Some studies have suggested that gastric-acid suppression from PPIs leads to:

This in turn may play a role in the development of cancer in the gastrointestinal system.

A 2019 study found that even whenH. pyloriinfection was eradicated, the long-term use of PPIs was still associated with a twofold increased risk for gastric cancer.

Other Risks From PPIsProlonged use of PPIs has been linked to:ReducedB12 levelsIncreased risk of pneumoniaIncreased risk ofhip fracturesIncreased risk of dementiaIncreased risk of heart attackIncreased risk ofchronic kidney disease

Side Effects of PPIs

PPIs like Prilosec and Prevacid (lansoprazole) are available over the counter without a prescription. But long term use can be problematic, even at the lower doses.

The U.S. Food and Drug Administration (FDA) says over-the-counter (OTC) PPIs should only be taken for the 14-day course up to three times a year.

In some cases, other medications (like an H2 blocker) may be appropriate.However, some people may still experience difficult symptoms after coming off PPIs and may need to go back on them at a higher dosage.

Stopping PPIs Abruptly Could Cause Rebound EffectsIf you have been taking PPIs for at least a few weeks, you should not stop taking the medication suddenly. Doing so may cause a rebound effect with stomach acid.People who take PPIs should discuss treatment options or changes with their healthcare provider.

If you have been taking PPIs for at least a few weeks, you should not stop taking the medication suddenly. Doing so may cause a rebound effect with stomach acid.People who take PPIs should discuss treatment options or changes with their healthcare provider.

Although PPIs are commonly prescribed in the U.S., there are alternative options available. These can include lifestyle modifications, alternative therapies, and other medications.

Other Medications

There are other medications that can be used instead of PPIs in the treatment of conditions like acid reflux.

H2 blockers are medications that lower the production ofhydrochloric acidin the stomach. They are absorbed quickly and the resulting acid suppression lasts for several hours after the medications have been taken. H2 blockers can also work to counter the effect of acid on the esophagus that causes heartburn.

H2 blockers include:

Lifestyle Changes

Lifestyle changes that may help include:

Alternative Therapy

Some alternative therapies that may be helpful as an alternative for PPIs include:

Herbal remedies that may be helpful include:

There are a number of steps that may help you to avoid acid reflux or GERD, and that could limit the need for omeprazole and other PPI medications.

Some ways to prevent acid reflux or GERD in the first place include:

Some medicines can relax the esophageal sphincter, causing reflux. Others can irritate the esophagus. Always speak with your healthcare provider before discontinuing or changing any medications.

Summary

PPIs like omeprazole are used to treat GERD and acid reflux, but they may cause elevated gastrin levels in the stomach. This may play a role in the development of gastric cancer.

Long-term use of PPIs may cause certain health risks, but other medications and lifestyle changes may help manage these conditions. Prevention strategies like stopping smoking and changes in diet may help manage GERD to avoid the need for medication.
