Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition that affects as many as 60 million Americans . And you can probably imagine, as a gut health doctor, I see patients with GERD on an almost daily basis. This condition is often dismissed as simple heartburn or shrugged off as mild digestive discomfort, but the truth is that GERD can cause a fair amount of pain and if left untreated, serious damage to the esophagus.
Plus, there’s a big problem in the way many people get treated for GERD. I’m not a person who enjoys criticizing others — and believe wholeheartedly that conventional and holistic medicine should find ways to work together — but in the case of GERD I can say with full confidence that if you’ve been seeing a conventional medicine doctor for acid reflux, there’s a good chance they’ve been leading you down the wrong path. In fact, there’s a good chance they’ll suggest a treatment plan that can end up doing more harm down the line.
So, let’s dive into the REAL cause of acid reflux and heartburn your doctor probably never told you — and what we can do to address it naturally.
What is GERD… and Why Does Conventional Medicine Get It So Wrong?
Acid reflux is often described as an “overproduction” of stomach acid, which causes it to backflow into the esophagus and cause a burning sensation in the neck and chest (thus, why it’s commonly referred to as “heartburn”) that can be extremely uncomfortable. If you’ve read any mainstream online health websites or seen your doctor for acid reflux, they’ll most likely describe it in this way. But here’s the thing:
In most cases, acid reflux is caused by an UNDERPRODUCTION of acid.
Yes, really! That wasn’t a typo. It’s caused by the exact opposite thing that most people think. So, how is this possible? Here’s what’s really happening with acid reflux. Essentially, your stomach acid is trying to break down the foods you eat. And that’s no easy feat! It takes a lot of acid to break down all that food, especially protein, which needs a specific enzyme called pepsinogen. But pepsinogen is not in the active form needed to break down protein when it is secreted. Pepsinogen gets converted to its active form, pepsin, ONLY in the presence of stomach acid (with a pH 1.5 – 2 required for activation) . Pepsin is the enzyme that breaks down protein into amino acids, which are then absorbed and utilized by your body as the building blocks for neurotransmitters, tissues, and more.
When your stomach lining is healthy, it can produce adequate amounts of stomach acid. When it detects food, it starts producing hydrochloric acid and gastric juices that begin breaking down the food before it empties into your small intestine. However, if stomach acid production is lowered by a combination of factors, including stress, imbalances in the gut microbiome, and OTC antacids (like H2 blockers or PPI’s), then the stomach fills up with gastric juice without enough acid in its best attempt to break down the food. When this happens, the pH in the stomach isn’t low enough to break down food you’ve eaten (especially protein) quickly and efficiently enough. So even though the pH of the stomach isn’t low enough to break down protein and other foods efficiently, it is still low enough to feel acidic when the contents back up as the stomach fills up, which causes the sensation of heartburn.
To summarize, acid reflux is most often caused by low stomach acid .
And here’s the interesting thing. Oftentimes, heartburn is just one of the many symptoms caused by the reflux of gastric juices into the esophagus. Acid reflux can also cause:
Whenever I see a patient for any reason, I look out for the symptoms above, which can be other signs that low stomach acid and acid reflux are issues that need to be addressed.
Aside from the typical symptoms above, what are the other signs and symptoms of low stomach acid?
Feeling like food sits in your stomach for hours
Avoiding red meat because it feels like a brick in your stomach
Gas and bloating IMMEDIATELY following a meal
Burping frequently right after eating
Undigested food found in the stool
Hair loss or brittle fingernails
You might be wondering: If LOW stomach acid is the problem, then why do antacid medications work so well for heartburn? Well, these medications can reduce that excess stomach acid that flows into the esophagus, but they don’t address the underlying cause of the problem , which is still too little stomach acid.
This is a common problem in conventional medicine, which is designed to pair a symptom to a pill and then call it a day, without considering the future consequences for the individual. Functional medicine, the type of holistic healthcare I have been practicing for over a decade, is all about focusing on the root cause of an issue. When you attack something at the source, you often eliminate the need for pills altogether. And in the case of acid reflux, avoiding medication is particularly important.
Why? Because the most prescribed medication for heartburn worldwide — called proton pump inhibitors (or PPIs) — can have some nasty and unexpected side effects.
The Surprising Truth About PPIs [What Big Pharma Doesn’t Want You to Know]
PPIs are one of the most prescribed drugs in the world, accounting for over 2.4 billion dollars a year in pharmaceutical revenue, and are also available over the counter. You’ll probably recognize them by their brand names, like Nexium (“the purple pill”) and Protonix (prescription options) and Prevacid and Prilosec (available over the counter). Now, I won’t knock the efficacy of these drugs in acute situations — they can work incredibly well to reduce the symptoms of heartburn and are very necessary for treating a stomach ulcer. Unfortunately, many doctors write prescriptions for an antacid drug for a patient, put six to twelve months of refills on it, and then completely forget about it. When the person calls in to renew the prescription (because after months of taking it, they are dependent on it), their doctor often renews it automatically. It becomes a reflex for both patient and doctor, and before you know it, a decade has passed. Or, a person will start taking over-the-counter options occasionally and this will turn from a few times a year to a few times a month and then to pretty much daily.
This is problematic because over the past decade or so, a shocking amount of research has revealed the side effects connected to chronic PPI use. Side effects like:
[Potential Side Effects of PPIs]
6. Increased risk of C. diff , which is a dangerous infection that could result in hospitalization or emergency surgery to remove part of the colon.
When you really think about the mechanism of action of PPIs, these side effects make sense. The stomach has evolved over millennia to create the perfect environment with the right amount of stomach acid needed to digest our food, and now we’re giving people medications to reduce that acid? Common sense says disrupting the natural state of the stomach will undoubtedly disrupt our gut health. What we didn’t know when these medications first came to market was that there are potential long-term consequences of these medications. The stomach doesn’t live in isolation — it’s the upstream part of the digestive tract, so anything that alters the environment in the stomach is going to have downstream effects in the small and large intestines.
“And as we know, our guts are the foundation of our overall health, so what happens in the gut, doesn’t stay in the gut — it will affect your entire body.”
For example, I had a 37-year-old male patient, let’s call him Max, who came to my office with gut health issues. About 6 months prior, he had been put on a PPI by a gastroenterologist for acid reflux issues, but had since developed diarrhea, bloating, gas, and fatigue. About 3 to 4 months in, he came in to see me about these ongoing symptoms. He wanted to get off the PPI, but was worried the acid reflux would come back, even while experiencing all of these side-effects. I explained to him these medications have a multitude of potential side effects, so we ran some tests and he came back with a positive SIBO breath test. We tapered him off the PPI, treated the SIBO, and worked on lifestyle and dietary approaches to prevent acid reflux WITHOUT medications. That’s what I’m going to discuss next.
How to Treat Acid Reflux Without PPIs
It’s clear that PPIs are drugs that should be avoided whenever possible. The good news is that just like depression isn’t a deficiency of an SSRIs, reflux is not a deficiency of an antacid medication. PPIs have their place in medicine, but they should only ever be taken for 2 to 4 weeks at a time (and if longer, only under the supervision of a physician with an endpoint to the treatment). Common practice among doctors and gastroenterologists is to put people on them indefinitely, without discussing nutrition or diet at all. In fact, most doctors and gastroenterologists I’ve spoken to don’t believe diet has anything to do with the health of the gut.
These are some of the natural options I suggested to Max and that I suggest to any patient with symptoms of acid reflux.
7 Ways to Reduce Reflux Naturally
1. Eat Early
Finish eating dinner at least 3 to 4 hours before bed. This gives you enough time to digest and for food to leave the stomach before you lay down.
2. Take a After-Dinner Walk
Research has shown that taking a walk after you eat may be able to reduce acid reflux. This is likely because it encourages digestion and keeps you upright.
3. Chew Gum After Big Meals
You won’t find me recommending gum very often, but chewing gum can promote gastric emptying. If you’re struggling with reflux — or trying to come off antacid medications — you might consider it as an occasional strategy for relief. Similarly, to walking, chewing gum for 30-minutes after a meal can help promote acid production and proper digestion.
4. Avoid Trigger Foods
Foods like tomato sauce, acidic juices, alcohol, chocolate, mint, cream-based dishes, and anything fried can be major triggers of acid reflux. If you’re trying to get your symptoms under control, it’s a good idea to eat trigger foods only in moderation. One key strategy I have recommended to patients is if they want to splurge with one trigger food, don’t combine another trigger food in the same meal. For example, if you really want to have pasta with tomato sauce, then don’t follow it with a chocolate pudding for dessert. Consider the effects of food-combining on exacerbating your symptoms.
5. Steer Clear Of Smoking (this causes reflux)
Smoking can contribute to reflux in more ways than one. First, it affects the lower esophageal sphincter (LES), the muscle that contracts automatically after food passes through the esophagus into the stomach, to keep food from refluxing back into the esophagus. Smoking lowers your LES pressure, which can make you more likely to have backflow of acid into the esophagus. The simple fact that smoking makes you cough more and have labored breathing can also be triggers for reflux. Lastly, smoking is just plain bad for you, because it has been linked to an increased risk for cancer, so don’t just quit for your acid reflux, quit to improve your general health as well.
6. Reach For Drug-free Options
Natural remedies such as deglycyrrhizinated licorice have been shown to reduce symptoms of reflux by promoting proper stomach acid production. Other commonly used options include slippery elm, which has a long history of being used by American Indians for a plethora of GI issues, and marshmallow root, which has traditionally been used to treat reflux and heartburn. Zinc carnosine is another option worth exploring, especially if you suffer from symptoms of low stomach acid. Why? Because zinc is needed to produce stomach acid and we sometimes don’t get adequate zinc in our diets.
7. Reboot Your Gut
I designed the Happy Gut ® Reboot 28-Day Cleanse to be a full gut health reboot. I’ve heard from dozens of patients that this program, which is designed for healing leaky gut and digestive issues, resolves their reflux completely within a week or two. For example, this is what one person shared about it:
“I had heard Dr. Pedre speak at a “Chef and the Doctor” event in NYC, and… I was surprised how much his recommended diet really helped me – within a week or two of following his cleanse, … my acid reflux disappeared – I used to have to take Tums every single night before bed and had to prop myself up on several pillows to sleep because of the acid – my acid reflux is now gone.”
Far too often in conventional medicine, we prescribe drugs without asking enough questions — questions about long-term safety, side effects, and whether there might be another way. Nowhere is this failure clearer than in the case of PPIs, which continue to be taken at alarmingly high rates. I hope that this blog has inspired you to think twice, do your research, and always look for the underlying cause of your health issue before you commit to a pill for life. And if you are currently taking a PPI, don’t stop it without speaking with your health practitioner or seeking the guidance of a functional medicine certified practitioner or naturopath.
