Mediterranean diet, alkaline water may be as effective as PPIs for laryngopharyngeal reflux

Alkaline water is water that's less acidic than regular tap water. This means it is rich in alkalizing compounds, including calcium, silica, potassium, magnesium, and bicarbonate.https://www.precisionnutrition.com/alkaline-water-legit-or-hoax


Seeing little relief with PPIs for patients, study author looked to dietary treatment for LPR

Treatment of laryngopharyngeal reflux (LPR) with alkaline water and the Mediterranean diet may be as effective as treatment with proton-pump inhibitors (PPIs), according to research published online in JAMA Otolaryngology–Head & Neck Surgery in September. Like gastroesophageal reflux disease, a similar condition, LPR occurs when acidic gastric juices in the stomach back up into the esophagus, but in LPR, the gastric juices reach the throat, resulting in symptoms such as hoarseness, sore throat, cough, and excessive mucous. 

In the study, researchers conducted a retrospective medical c­hart review comparing the change in Reflux Symptom Index (RSI) in two groups of patients, those treated between 2010 and 2012 with PPIs and standard reflux precautions and those treated between 2013 and 2015 with a plant-based Mediterranean diet and alkaline water that had a pH of at least 8. The team found that 54.1% of patients in the PPI group achieved a clinically meaningful reduction of at least 6 points, but 62.5% in the dietary group achieved similar results. Furthermore, those in the dietary group achieved a greater reduction in RSI: 39.8% compared with 27.2% in the PPI group.

"It's pretty clear that this data suggests that we, as health care professionals, need to start getting patients educated so they understand how important a role diet plays," said study lead author Craig H. Zalvan, MD, FACS, chief of otolaryngology and medical director at The Institute for Voice and Swallowing Disorders at Phelps Hospital in Sleepy Hollow, NY.

Zalvan said he thought to study dietary treatment for LPR after seeing that a sizable number of patients don't get much relief with PPIs.

"The standard of care for LPR has always been PPIs, and many of my patients got better with them, but a bunch didn't. At most it helps about 50% of patients," Zalvan said. "I looked at chronic diseases like heart disease, diabetes, and stroke, and their successful treatment with a plant-based diet, so I thought there's got to be a better way to treat LPR with diet [as well] and not have people constantly taking pills."

Zalvan added that the idea to incorporate alkaline water into treatment stemmed from prior research conducted by Jaime Koufman, MD, at the Voice Institute of New York in New York City, which suggests that alkaline water may benefit patients with reflux because it deactivates pepsin and acts as an acid buffer.

Zalvan said that as medication experts and readily accessible members of the health care team, pharmacists can help boost the signal about treatment options for LPR.

"Pharmacists can reinforce that PPIs are meant to be short-term medications for an acute problem, and that in order to get off them, diet will play a major part," Zalvan said. "If patients come to me and I say they should try diet, and then they go to the pharmacy and the pharmacist says they should try diet, patients are more likely to try diet."
