I suspect that you, like me, have experience ‘heartburn’ or uncomfortable regurgitation from time to time. Many years ago, my husband was diagnosed with another digestive problem – esophagitis, most often from acid damaging the lining of the esophagus. Luckily, it was temporary, although the healing was not immediate.
This came to mind recently when within one month, three different friends (no names shared here) mentioned GERD, sometimes referred to as acid reflux. One of them was clearly suffering. The conversations provided me the nudge to write about Proton Pump Inhibitors, often used to treat such discomfort.
It may not sound like a ‘sexy’ topic or one with much Pizzazz, but it’s helpful info for those (almost all of us) who occasionally or frequently suffer digestive problems. Consider your self-care ahead of time.
What is a PPI – or Proton Pump Inhibitor?
Proton Pump Inhibitor (PPI) is the term for a large class of medicines designed to decrease stomach acid production. Technically, they function by targeting and then hindering the stomach’s acid-producing proton pump.
These PPIs decrease stomach acid by blocking an enzyme called hydrogen-potassium ATPase or the “proton pump.” The inhibitors prevent the pump (in the stomach) from finalizing the chemical reaction to make the stomach acid. They don’t stop acid production totally. Good thing, since we need it for food digestion, nutrients and thus, energy.
Gastric acids serve vital purposes. They help us digest food by breaking it down. They also maintain health by killing harmful germs in our gut. [For some related situations when traveling visit: Montezuma’s Gut – Digestive Disorders at Home or Abroad.] Bottom line is that gastric acid is necessary.
However, too much stomach acid in the wrong place is a different matter. The same as too much water would be detrimental if in your lungs versus in your glass. Or too much fire in your house rather than at your stove. Gastric acids can irritate or even damage parts of our digestive system. The small intestine, (especially the duodenum portion) or our esophagus are quite susceptible. The discomfort spectrum runs the gamut from mild heartburn to producing duodenal ulcers.
What Conditions do PPIs Treat?
As mentioned above, Proton-Pump Inhibitors (PPIs) are used to treat conditions stemming from too much gastric acid. These commonly include:
Acute Heartburn. Generally Over-the-Counter (OTC), quick acting antacid products (such as Tums or Mylanta) are the first option or H2blockers like Pepcid or Tagamet
GERD (GastroEsophageal Reflex Disease). This chronic acid reflux is a bit harsher and longer standing than mild heartburn. Similarly, with GERD, stomach acid leaks into your esophagus, irritating it to the point of heartburn, but can escalate further, damaging the esophagus lining (as in the inflammation of esophagitis). As with other conditions, PPIs are used to reduce the acid and give the esophagus time to heal.
Duodenal Ulcer when the stomach acid damages part of the small intestine.
Peptic Ulcers occur from the same process, but when the acid damages the stomach’s protective inner lining. Some ulcers that result from a person taking too many NSAIDs (nonsteroidal anti-inflammatory drugs like Aspirin or Acetaminophen, aka Tylenol) can also be treated with PPIs.
Infection (from H. pylori bacteria) is often treated with a PPI so that it can help balance the pH of the stomach’s acid (lowering the acid) and allowing antibiotics to more easily kill the bacteria.
Rare Zollinger-Ellison Syndrome may also be treated with PPI to reduce its symptoms. In this condition, tumors release a hormone that promotes the production of extra gastric acid; the PPI helps reduce it.
What, When, How Long for PPI
The amount of PPI you take (capsules / tablets or powder in food) depends on the severity of your condition and the brand chosen. Usually prescribed to be taken 30 minutes before eating – it might be just before breakfast or breakfast and dinner. Some folks demonstrate relief with a dose every other day. Still, they are not the swiftest in extending relief. Both antacids offering quick relief, or the commonly prescribed H2blockers (a bit slower than antacids), generally act faster at relieving symptoms than PPIs.
My favorite first choices for mild and temporary situations are more self-help options. Activated charcoal, which does not reduce gastric acid or treat heartburn, often relieves symptoms of gas and indigestion. Papaya Enzyme (which I also keep in the house) is fairly quick and effective for mild heartburn or indigestion. They are both quick acting for mild cases. Activated Charcoal is not to be taken long term for more than a few days since (similar to PPIs) it can interfere with absorption of good nutrients.
PPIs tend to be slower acting than any of these products. Often, you’ll find it takes 24 hours or up to 4 days to obtain full relief. However, for chronic conditions, its effects last longer than those of the other therapies.
Recognizing PPI Names
Medicines in the Proton Pump Inhibitor class that treat symptoms noted above, can be found both as Over-the-Counter (OTC) or prescription drugs. It’s best to attempt a couple days of treatment outside the PPI category if symptoms are new for you. However, if it becomes apparent that this is becoming a chronic and frequently uncomfortable issue, then you may feel the need to graduate to PPIs – at least for a while.
Some of the common brands have recognizable names (even if the generic names are totally undecipherable). They include the following, with OTC products noted, which can be obtained both by a prescription or OTC.
- AcipHex (Rabeprazole)
- Dexilant (Dexlansoprazole)
- Nexium (Esomeprazole) OTC
- Prevacid (Lansoprazole) OTC
- Prilosec (Omeprazole) OTC
- Protonix (Pantoprazole)
- Zegerid (Omeprazole) OTC. While not simply old-fashion sodium bicarbonate, it does contain such.
Possible Side Effects of PPI Usage
All drugs, whether OTC and seemingly innocuous or not, have potential side effects. While many people are prescribed PPIs without suffering annoying or dangerous outcomes, others may experience them either mildly for a short term or risk serious complications.
Short-Term
Any of these may come on suddenly or develop after a couple days. They are in alphabetical, not worsening order.
-
- Abdominal pain
- Constipation
- Diarrhea
- Dizziness
- Dry mouth
- Fever
- Gas
- Headaches
- Itching
- Light-headedness
- Rash
- Vomiting
Long-Term or Serious Effects
Kidney Disease. PPIs may increase chances of developing chronic kidney disease or cause a current illness to worsen and progress further. Look for signs of hands, feet or ankles swelling or experiencing less urgency to urinate.
Serious Nutritional Deficiency. Due to uptake of certain nutrients inhibited by the PPI, many muscle and nerve conditions can be severe. (See Next Section).
Various Allergic Reactions. Rash, hives, swelling or difficulty breathing can be seen. This can also include red, peeling or blistering skin.
Diarrhea or Colitis. Often triggered by “C. diff” (or Clostridioides difficile), this can stem from imbalance of gut bacteria when taking certain medications.
High Fever.
Dizziness or Confusion. (Due to decreased vitamin B12)
Numbness, tingling or pain in hands or feet. (In part due to decrease in B12)
Fractures. The FDA cautions that PPIs can increase the risk of bone fractures (especially of hip, spine or wrists). This is again in part due to the body’s inability to absorb enough of the bone-strengthening minerals, especially calcium.
Heartbeat irregular. Often accompanied by fatigue and shown with low magnesium levels.
Due to any of these potential serious problems, taking short-term antacids or a H2Blocker are often the preferred first choice of medical treatment for mild or transitory issues.
Addressing 4 Nutritional Deficiencies due to PPI Impact
Long term use of PPI therapy is discouraged. For those who depend on these drugs, nutritional support is essential to avoid any of the serious side-effects noted above. In general terms, these nutrients which we usually rely on from our foods are significantly impaired due to reduced gastric acids. Remember that the upside of gastric acid is that it helps break down our food and provides needed elements.
A few nutrients in particular are substantially affected due to their reliance on stomach acid for the body’s optimal and necessary absorption. Each of these needs to be supplemented if taking PPI drugs.
Calcium. This mineral affects muscle function, bone health and nerve transmission. PPIs can affect – and partially disrupt – all of these.
Vitamin B12 (especially important for vegetarians). When decreased stomach acids reduces B12 uptake it can lead to anemia or fatigue and neurological complications. B12 is essential for our DNA repair, neurological function, and Red Blood Cell production.
Iron. Element is crucial for oxygen transport and energy production; PPIs can lead to anemia.
Magnesium. Aside from muscle cramps or seizures and heart arrhythmias, long-term PPI use can affect bone health as well as other muscle and nerve functions.
FINAL THOUGHT
As is almost always the case, my own opinion is that it’s best to start treatment of any kind with the least invasive approach. In the case of indigestion, heartburn or stomach issues, there may be several steps before PPI therapy.
- Diet Changes.
- Papaya Enzyme for mild transitory heartburn or regurgitation. Activated charcoal for bloating, gas and general intestinal discomfort, but generally not used for more than a few days due to its absorption of good nutrients. Both work quickly.
- Antacids. Because they work locally in the stomach, they have fewer side-effects and work faster than #4 below. Examples are Mylanta, Rolaids, Tums, Alka-Seltzer.
- H2 Blockers (histamine blockers). They are absorbed in the bloodstream, so take longer to work than antacids, but tend to have longer relief.
- Proton-Pump Inhibitors.
Diet changes would include balancing food groups and avoiding food products that seem to trigger events for you. THAT in combination with ADDED hydration and extra movement without a doubt would be my first course of action for repeated but only occasional occurrences. While this may sound like a trite, obvious suggestion, it’s also the cheapest, and most healthy possible solution.

Man asks, “how do you know?”
Woman “Don’t ask me, just a gut feeling I guess.”
