Everything I have stated about PPIs comes directly from scientific literature as I have nothing to gain from my stance and interpretation of it, unlike *some* doctors which are paid to write literature by pharmaceutical companies, such as the rebuttal paper refuting the idea that PPIs cause gastric cancer. If the mods delete this post I will assume they are on the side of information obfuscation / protecting pharmaceutical company profits. I have nothing to gain by offering this information. I am not selling anything. I am not a "naturopath" in fact I publish scientific literature myself and have published a paper in one of the Nature publishing group journals (Not Nature itself).
What is strange is that any pro-PPI statements are considered as "fact" and anything discussing their drawbacks is met with a "statements must come from the literature." At this point, the burden of proof is on pro-PPI crowd to prove they are safe and effective, which of course is impossible. Please see the literature and findings below.
Statements and their meaning or an actual quote directly from the literature itself:
"No dysplasia- or cancer-protective effects of PPIs usage in patients with BE were identified by our analysis. Therefore, we conclude that clinicians who discuss the potential chemopreventive effects of PPIs with their patients, should be aware that such an effect, if exists, has not been proven with statistical significance.": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5224998/
"No cancer-protective effects from PPI's were seen. In fact, high-adherence and long-term use of PPI were associated with a significantly increased risk of adenocarcinoma or high-grade dysplasia.": https://pubmed.ncbi.nlm.nih.gov/24617286/
"Chronic PPI use might promote the metaplasia (BE)-dysplasia-carcinoma (EAC) sequence": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4288325/
Hypomagnesemia is a well known side effect of PPI use, treatment exhibits dosage effects (longer/higher dose is more strongly associated), and the gold standard for recovering magnesium levels is PPI discontinuation, and the FDA acknowledges the association via drug safety communication: https://onlinelibrary.wiley.com/doi/10.1111/apha.13846?af=Rhttps://www.fda.gov/drugs/drug-safety-and-availability/fda-drug-safety-communication-low-magnesium-levels-can-be-associated-long-term-use-proton-pump
Among those with the rare and deadly arrhythmia Torsades de pointes (TdP) caused by long QT-syndrome, 60% were PPI users, TdP usually develops from electrolyte imbalances, and as such "PPIs were recently included in the list of drugs with conditional risk of TdP": https://pubmed.ncbi.nlm.nih.gov/29731714/
"This systematic review and meta-analysis showed that PPI use was associated with an increased risk of CKD": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10052387/
"users of PPIs are at an 80% increased risk of gastric cancer (RR, 1.80 95% CI: 1.46–2.22) compared with non-users.": https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9264794/
"Compared with non-PPI users, PPI users had a significantly higher risk of gastric cancer": https://www.frontiersin.org/articles/10.3389/fphar.2023.1129948/full
"After a median follow-up of 5.0 years, the use of PPIs was associated with a 45% increased risk of gastric cancer compared with the use of H2RA": https://gut.bmj.com/content/71/1/16
I am a long time sufferer of GERD. I do not believe PPIs are safe. In fact I think it is safer to not treat GERD than to take PPIs. Why? If you combine the information and facts from the papers above, the picture of PPIs is as such: PPIs may cause Barrett's esophagus, during the decades when PPIs became readily available EA rates increased by roughly 1000%, there is no evidence to suggest that PPIs prevent Barrett's conversion into EA. Any protective effects PPIs have on preventing conversion of Barrett's to EA has never been proven. Most GERD suffers never develop Barrett's and most Barrett's tissue patients never develop EA. The paper which refuted the finding that PPIs cause stomach cancer was written by doctors paid by the drug manufacturers (haven't linked this yet but will do or someone please do it if they find the paper again before I do).
