Alternatives to PPIs and H2 Blockers

Gastroesophageal reflux disease (GERD) is estimated to affect 10-20% of the Western world and up to 30 million people in the United States alone.1 Sixty percent of adults experience the symptoms and the impact of GERD over a period of 12 months, whereas 20% to 30% of individuals have weekly symptoms.1 The most popular treatments, stomach acid reducers, are a booming business. Both H2 blockers and proton pump inhibitors (PPIs) are used widely, with the latter currently being taken by an estimated 15.3 million Americans.2

But is this really the best way to treat GERD? Taking an over-the-counter acid blocker for occasional heartburn symptoms may not be a big issue, but in practice, many patients with chronic reflux are prescribed acid blockers indefinitely. Research suggests that this long-term approach may have significant drawbacks.

A 2017 meta-analysis of 7,703 patients found that the use of gastric acid suppressants was associated with a significantly increased risk of recurrent C. difficile infection (CDI).3 Risk factors for recurrent CDI include older age, concomitant antibiotic use, and comorbid conditions. Up to 50% of patients with CDI are using concomitant gastric acid suppressants.3

A 2017 study in the British Medical Journal Open suggested a substantially increased risk of death among long-term proton pump inhibitor (PPI) users, including those without gastrointestinal conditions.4 Since then, some observational studies have described an association between PPI use and the risk of the development of chronic kidney disease and its progression to end-stage renal disease.5 A meta-review also suggested a correlation between PPI usage with an increased risk of dementia,6 as did a cohort study in JAMA Neurology.7 However, data on the association between gastric acid suppression and dementia are conflicting.8,9 A study investigating the effects of PPIs on cognitive decline in a study of middle-aged and elderly twins in Denmark found no association.9

Given these risks, is there a better way to treat the increasingly common issue of GERD?

She is also a fellow & guest faculty for the Arizona Center for Integrative Medicine.

Lifestyle modifications that have been studied for GERD include weight loss, head-of-bed elevation, and avoidance of tobacco, alcohol, and late-night meals.10 Another modification that has been suggested is avoiding foods that can aggravate reflux symptoms—e.g., caffeine, coffee, chocolate, spicy foods, highly acidic foods (oranges, tomatoes), and fatty foods. Recently, a prospective cohort study also found that smoking cessation significantly improved GERD symptoms in patients with normal body mass index and severe symptoms.10

Clinical studies have also suggested a relationship between GERD and anxiety, as well as depression.11 A 2017 cohort study of Australian men observed a strong independent association between GERD, anxiety, and depression, partly mediated by poor sleep quality.11

Clinicians looking for insight into how to treat gastrointestinal conditions safely by addressing the underlying cause and prioritizing lifestyle treatments can attend IFM’s GI Advanced Practice Module (APM). Clinicians will come away with tools and strategies to help prevent GERD, address problems with the microbiome, and improve overall gastrointestinal function.

Understanding the Mind-Body Connection Can Help GI Patients

Given the strong mind-body/brain-gut connection, it is clear that when the normal integrity of the GI tract is compromised, distant systemic complaints can result, even in the absence of overt GI symptoms. Integrative approaches may be helpful for reducing symptoms and reestablishing a healthy gut and a healthy mind.

The Gut-Brain Axis & Systems Biology

The gut-brain axis is the bidirectional communication between the gut and the brain, which occurs through multiple pathways that include hormonal, neural, and immune mediators. Interestingly, the signals along this axis can originate in the gut, the brain, or both, with the objective of maintaining normal gut function and appropriate behavior.
