G.K. Chesterton described a scenario like this:
“There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, “I don’t see the use of this; let us clear it away.” To which the more intelligent type of reformer will do well to answer: “If you don’t see the use of it, I certainly won’t let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it.”
In other words, beware of tearing down structures until you fully understand their benefit.
Chesterton’s Fence can also be thought of as the Precautionary Principle. Not following this principle led to scientific practices like frontal lobotomies or removing the entire large intestine because doctors didn’t understand the benefits of these structures or the consequences of removing them.
A narrow range of focus, i.e., this organ is causing a problem, or we don’t know why it’s here, led to drastic action that resulted in unforeseen, disastrous consequences.
I believe that such is the case with our stomach acid.
The stomach is essentially a lined bag filled with acid. Stomach pH is from 1.5 to 3.5, acidic enough to burn a hole in your shoe. However, the mucus layer of the stomach protects it from being destroyed by the acid. The acid in the stomach helps dissolve and digest the food chewed up by the teeth and swallowed.
Stomach pH is needed for breaking down proteins. Stomach acid also plays a role in absorbing minerals such as calcium, zinc, manganese, magnesium, copper, phosphorus and iron. It activates intrinsic factor, which is needed for B12 absorption in the small intestine.
Stomach acid regulates the rate of gastric emptying, preventing acid reflux.
Fast-forward to a condition called gastric esophageal reflux disease, or GERD. GERD affects about 20% of Western countries, characterized by high esophageal pH and reflux of the stomach acid and stomach contents into the esophagus. While the stomach is designed to handle a shallow pH environment, the esophagus is not. A doorway called the lower esophageal sphincter, or LES, keeps stomach contents where they should be–in the stomach.
In GERD, the tone of the LES is weak, resulting in a backflow of stomach contents. This can damage the esophagus, causing heartburn, pain, bad breath, coughing and even problems like ear pain, sore throat, and mucus in the throat. Silent reflux occurs when these symptoms occur without burning.
The symptoms occur from the stomach’s acidic contents irritating the more delicate tissues of the esophagus. So, rather than treat the root problem, i.e., the reflux, drugs like proton pump inhibitors (PPIs), H2 blockers, and buffers like Tums are recommended to reduce the stomach’s acidity.
Essentially, with GERD, we are tearing down Chesterton’s Fence to pave a road without taking even a moment to consider why the fence might be there in the first place.
About 12% of people are prescribed PPIs. They are given for GERD, gastritis, and IBS symptoms like bloating and stomach pain. Most of my patients are prescribed them for virtually any stomach complaint. PPIs, it seems, are the hammers wielded by many GPs, and so every digestive concern must look like a nail. Most people are put on them inevitably, without a plan to end the use and address the root cause of symptoms, which in most GERD cases are low LES tone.
PPIs raise stomach pH, disrupting stomach function. This causes issues with mineral absorption and protein digestion. Their use results in B12, vitamin C, calcium, iron, and magnesium deficiencies. Many of these deficiencies, like magnesium deficiency, can’t be tested and therefore might show up sub-clinically in tight muscles, headaches, painful periods, disrupted sleep and anxiety, and constipation. Therefore they fly under the radar of most primary care doctors.
No one connects someone’s heartburn medication with their recent onset of muscle tightness and anxiety.
Many of my patients report difficulties digesting meat and feeling bloated and tired after eating, particularly when consuming a protein-rich meal. They conclude that the meat isn’t good for them. The problem, however, is not meat but that stomach acid that is too diluted to break down the protein in their meal, leading to gas and bloating as the larger protein fragments enter the small intestine.
Many digestive problems result from this malabsorption and deficiency in stomach acid, not too much. Zinc is required for stomach acid production, and one of the best sources of zinc is red meat (zinc is notoriously lacking from plant foods). I have recently been prescribing lots of digestive enzymes and zinc to work my patients’ digestive gears.
Therefore, beware of tearing down a fence without understanding why it’s there. Stomach acid is essential for digesting our food, and regulating blood sugar and building muscle mass through protein digestion.
It is necessary for mineral absorption and B12 digestion. Our stomachs were designed to contain an extremely low pH. They evolved over millennia to do this. Stomach acid is low for a reason. It’s highly unlikely that our bodies made a mistake when it comes to stomach acid.
Therefore, beware of messing with it.
Consider that our bodies know what they’re doing. Consider the importance of finding and treating the actual root cause, not one factor that, if mitigated, can suppress symptoms while causing a host of other problems.
Don’t block your stomach acid.
As Hippocrates said, “All disease begins in the gut.”
It is the boundary between us and the outside world, the border where our body carefully navigates what can come in and nourish us and what should stay outside of us: our fence. Beware of tearing it down.
