New Study Finds Long-Term Use of Acid Reflux Medication Linked to Increased Risk of Dementia
A recent study published in the journal Neurology has found a potential connection between the long-term use of proton pump inhibitors (PPIs) – a common prescription medication for acid reflux – and an increased risk of dementia. The study, which followed 5,712 participants over an average of 5.5 years, revealed that individuals who took PPIs for four-and-a-half years or more had a 33% higher risk of developing dementia compared to those who did not take the drugs.
However, it is important to note that the study only established an association and does not prove a direct causation between PPI use and dementia. The research also solely focused on prescription medications and did not consider over-the-counter acid reflux drugs.
Acid reflux occurs when stomach acid flows into the esophagus, causing symptoms such as heartburn and ulcers. PPIs work by reducing stomach acid production, but prolonged use has been linked to other health risks such as stroke, bone fractures, and chronic kidney disease.
The study’s participants, who were aged 45 and older and did not have dementia at the start of the study, were divided into groups based on their PPI use. Of the participants who took PPIs for more than 4.4 years, 58 people developed dementia, compared to 415 cases in the group that did not take the drugs. After adjusting for various factors, including age, sex, and pre-existing health conditions, the researchers found that individuals who took PPIs for more than 4.4 years had a 33% higher risk of dementia.
The authors of the study emphasize the need for further research to confirm these findings and explore the potential reasons for the association between long-term PPI use and dementia. In the meantime, individuals who are currently taking PPIs are advised to consult with their doctor before making any changes to their medication regimen. Abruptly stopping these drugs could result in worsened symptoms.
The study was supported by the National Institutes of Health, including the National Heart, Lung, and Blood Institute. While the findings are concerning, it is essential for individuals to consider these results alongside the benefits that PPIs provide in managing acid reflux symptoms. Further research is needed to provide a clearer understanding of the potential risks associated with long-term PPI use and to explore alternative treatment options for acid reflux.
