Forty-eight percent of Americans suffer from heartburn at least once every month. Forty-eight percent! Some seek over-the-counter remedies, and others get medical advice from their doctors. Heartburn is caused by stomach acid in the esophagus. If we reduce stomach acid, we will have fewer heartburn symptoms, right? This circular logic has led to a class of medications called proton pump inhibitors (PPI), and one of them, Nexium, generates six billion dollars per year by itself!1

Proton Pump Inhibitors (PPI) Mechanism of Action

Proton Pump Inhibitors (PPI) irreversibly drastically limit acid production for days within our stomach. PPIs work by irreversibly binding to and blocking the hydrogen/potassium adenosine triphosphatase (H⁺/K⁺‑ATPase) enzyme system located on the secretory surface of gastric parietal cells. By shutting down this “proton pump,” which is the final step in the pathway of gastric acid secretion, PPIs drastically reduce the amount of hydrochloric acid released into the stomach lumen, leading to a sustained and significant decrease in gastric acidity. This enzymatic system, or proton pump, is directly responsible for the secretion of hydrogen ions into our gastric lumen, making stomach acid. PPIs take two to three days to reduce stomach acid production significantly. This mechanism is reversed two to three days after the medication is stopped. Proton pump inhibitors are stronger and last longer than H2 antagonist medications like Pepcid.2 3

Proton Pump Inhibitors (PPI) Side Effects

Short-term (less than two weeks) usage of PPIs is tolerated, and side effects include headache, nausea, vomiting, flatulence, burping, bloating, diarrhea, constipation, abdominal pain, worsening reflux, fatigue, brain fog, and dizziness. Rarely, allergic reactions, including rashes and anaphylaxis, may occur.4

On the other hand, long-term usage of PPIs has an increased risk of side effects, some severe, and they should only be used when all other options have been exhausted. After long-term use, proton pump inhibitors cause calcium deficiency, magnesium deficiency,5 iron deficiency (leading to anemia), zinc deficiency (leading to low levels of testosterone in men),6 B12 deficiency (from PPIS hindering production of your stomach’s intrinsic factor),7 vitamin C deficiency, Small Intestinal Bacterial Overgrowth (SIBO),8 increased risk of developing C. diff dysbiosis,9 accelerated skin aging,10 bone fractures,11 increased risk of community-acquired pneumonia,12 development of food allergies,13 chronic interstitial nephritis (leading to kidney failure), gastroparesis, upper gut dysbiosis, hindered mitochondrial health (supplementing with Ubiquinol might help prevent and relieve this side effect), increased risk of gastric cancer, developing or worsening dementia, developing or worsening Alzheimer’s Disease, developing or worsening cardiovascular disease, and even developing or worsening heart arrhythmia.14 15

The risk of SIBO increases when taking PPIs because opportunistic bacteria, which are usually reduced by stomach acid, survive and colonize our small intestine. The survival of excess microorganisms is the reason for the increased risk of community-acquired pneumonia and C. diff in people who take PPIs. Bone fractures and osteoporosis risk increase because the disruption of acid production interferes with bone mineralization. The increase in heart palpitations associated with PPI use is related to decreased magnesium levels within our body.

The following is a link to medications that interact with PPIs.

Fix Your Gut Recommendations

If I had to use a PPI, I would initially choose one of the first-developed PPIs, such as omeprazole or lansoprazole. There is a theory that some of the newer PPIs that are “active” forms of the originals (esomeprazole and dexlansoprazole) may have an increased side effect profile.16

If I had to use a PPI long-term for specific medical reasons (Zollinger-Ellison syndrome for example), I would take a digestive enzyme like Now Pancreatin with every meal. I would also take an excellent sublingual B12 supplement, take Epsom salt baths frequently, and supplement with magnesium. I would monitor my body’s storage levels of vitamin C, calcium, iron, and zinc and supplement when necessary. I would also take certain supplements and change my lifestyle to stave off osteoporosis, including getting proper sunlight exposure, following the Perfect Health Diet, and supplementing with vitamin K2, boron, calcium when needed. Finally, if you start to develop H. pylori dysbiosis symptoms like increased bloating and belching, I would follow my H. pylori protocol.

When someone attempts to stop long-term PPI use, rebound reflux occurs, sometimes quite severely. Slowly tapering off PPIs might be necessary to reduce rebound reflux symptoms. Discuss a tapering dosage schedule with your healthcare professional. A basic tapering plan would be taking a PPI every other day for a few weeks, then every third day for a few weeks, then every fourth day for a few weeks, then every fifth day for a few weeks, then stop. Taking digestive enzymes like Now Pancreatin with meals may help with the medication tapering period. Making your stomach acidic during meals using betaine HCL also helps improve digestion. Eating smaller meals and consuming less than ten ounces of water during meals might help. Most of your water consumption should be in between meals. Do not eat any food three hours before bed when possible. Going on a low-acid diet to prevent further esophageal inflammation can be helpful. Finally, using a supplement like Reflux Raft when rebound reflux is at its worst to get relief might also be useful.

PPIs are quite harmful medications when used long-term, and they are over-prescribed. Unlike Miralax and Reglan, both medications that I believe should seldom be used, if at all, PPIs are indicated in specific medical circumstances, including severe esophageal/gastric inflammation, esophageal/gastric perforations, esophageal/stomach surgery, or Zollinger-Ellison syndrome. Most doctors prescribe PPIs like they are candy if you are suffering from heartburn or GERD. You can easily get Prilosec over the counter at most pharmacies within the United States. PPIs are just a bandage for your GERD; therefore, they should be used only acutely.

If you are on PPIs and want to correct the deficiencies they cause, quit PPI medications, and/or try to “fix” your digestive issues, contact me for coaching, so hopefully, you will not have to be on them forever.
