This is the third article of a four part series on acid reflux and GERD. Read the first article on the underlying cause, the second article on the myths of H. pylori and low stomach acid being the major causes and the final article on the myths of trigger foods and GERD diet that works without drugs.
The current strategies for treating GERD
Everyone agrees that stomach contents refluxing into the esophagus and beyond is the underlying cause of:
- GERD symptoms such as heartburn, cough, sore throat, etc.
- inflammation (esophagitis)
- laryngopharyngeal reflux (LPR)
- Barrett’s esophagus
- esophageal cancer
But, there are clear differences in how modern medicine deals with the problem.
1. Surgeons tighten the LES surgically (i.e. Stretta and Linx techniques have the same goal)
2. Pharma companies neutralize stomach acid (antacids) or block its release (H2 Blockers) or production (PPI drugs)
And, each of these approaches is flawed.
Surgery for GERD
Surgical procedures seek to improve the barrier between the esophagus and stomach by strengthening the lower esophageal sphincter. In the Nissen Fundoplication procedure for example, the surgeon pulls up the very top part of the stomach and tightly secures it around the esophagus with sutures effectively tightening the LES. Though this procedure does not treat the underlying cause of acid reflux, when performed right, it can minimize reflux. But a fundoplication involves invasive surgery which carries the risks of infection and complications. And the truth is, many people who have had the operation continue to have symptoms and must remain on acid reducing drugs. One of our readers, N. Baily’s experience (FTD – Heartburn 6th from the top) illustrates this point. Also, repeat operations may be needed because the surgical tightening can loosen up over time.
One significant problem with LES tightening procedures which I touched upon in my first article is the side effects including:
- stomach pain
- difficulty swallowing
- inability to belch or vomit
- bloating and flatulence- from trapped intragastic and intestinal gas [i]
I don’t recommend these approaches until all other avenues have been exhausted. Even then, it’s a stretch.
Acid Reducing Medicines
The second approach is based on the idea that most GERD symptoms and tissue damage are caused by stomach acid, as opposed to bile, enzymes or bacteria which may also be present. By the way, stomach acid itself isn’t the problem as long as it stays in the stomach. Regardless, there has been a virtual explosion in the development of medicines attacking stomach acid.
Remember from my second article, stomach acid is essential for health and digestion, but it becomes problematic when it escapes into the esophagus.
The least invasive medicines which temporarily neutralize stomach acid are antacids.
H2 antagonists limit the release of acid from parietal cells that line the stomach by blocking the production of histamine. H2 blockers are much more powerful than antacids and were actually the first ever blockbuster drugs.
More recently, even more powerful proton pump inhibitor (PPI) drugs were developed. PPIs literally shut down acid production in parietal cells inducing profound and sustained suppression of stomach acid. PPIs are now one of the most commonly prescribed drugs accounting for 95 million prescriptions in 2009 according to an FDA review. Most PPIs (and H2 blockers) are now available over the counter as well.
Though newer PPIs are very potent, they are still not able to fully control symptoms in almost 50% of the people who take them.[ii] This has led to renewed efforts to develop even stronger acid suppressing drugs. One recent journal article noted the shortcomings of these agents being “incomplete acid suppression in the majority of patients”.[iii] To overcome this “shortcoming”, doctors now routinely prescribe both PPI and H2 blocker drugs together in an attempt to completely shut down stomach acid 24/7.
I presented our own study findings at the Digestive Disease Week meeting in 2013 where gastroenterologists and other health professionals from around the world get together each year. One issue that even concerned many GI doctors (they set up a special session to discuss the problem) was the excessive use of high dose PPI drugs and the increasing practice of combining PPIs with H2 blocker drugs. I agree. There is reason for grave concern.
The dark side of acid suppression
We now know clearly that reducing stomach acid with PPI drugs:
- Does not address the root cause of GERD
- Does not provide adequate symptom relief for almost half the people being treated
- Diminishes vitamin B12 absorption (risk of anemia) and likely other vitamins
- Diminishes minerals absorption including calcium (risk of bone fractures), magnesium (risk of serious cardiovascular, neurological problems and also bone health) and iron (risk of anemia)
- Increases risk of bacterial overgrowth in the small intestine and stomach since stomach acid is part of our bacterial control system
- Decreases the diversity of gut microbiota
- Increases the risk of C diff and other GI infections likely because our acid barrier to outside pathogens is missing and our protective micribiota is impacted (see above two bullets)
- Increases the risk of pneumonia likely from reflux of gut microbes into the lungs
- Increases the risk of serious kidney disease
- Increases the risk of dementia
- Increases the risk of heart attacks
- Increases the risk of early death
Many of these issues are discussed in detail with supportive citations in Fast Tract Digestion Heartburn.
Drugs and surgery for GERD have become universal and standard treatments for GERD: however, they have several shortcomings:
- They don’t address the underlying cause of acid reflux
- They don’t fully address symptoms for many people
- They carry significant side effects and health risks
Stay tuned for the final article where I address dietary approaches to GERD. I will challenge this 2013 statement by the American Medical Association’s Continuing Medical Education (CME) program for doctors and gastroenterologists:
“Routine global elimination of food that can trigger reflux is not recommended in the treatment of GERD.”
