Proton pump inhibitors (PPIs) are commonly used medications to treat acid-related conditions, including gastro-esophageal reflux disease (GERD). Gastroenterology guidelines mention the importance of CYP2C19 in PPI metabolism and the influence of genetic variations on variable responses to PPIs, but do not currently recommend the genotyping of prior to prescribing PPIs. There are strong data to support the influence of genetic variations on the pharmacokinetics of PPIs and clinical outcomes. Existing pharmacogenetic guideline recommendations for dose increases focus on and erosive esophagitis indications, but PPIs are also the main therapy for treating GERD. Recent data suggest GERD patients being treated with a PPI may also benefit from genotype-guided dosing. We summarize the literature supporting this contention and highlight future directions for improved management of patients with GERD through precision medicine approaches.

Department of Internal and Family Medicine, Faculty of Medicine, The Hashemite University, Zarqa, Jordan.

Introduction: Common clinical problems are frequently seen in medical students. Gastroesophageal reflux disease (GERD) is increasingly seen in clinics and is taken seriously into consideration; from this point, we start discussing this disorder. The most important part is to find out the prevalence of GERD among medical students and determine the most dominant risk factors that affect the prognosis of the disease.

Background: As mental health awareness increases, healthcare professionals must understand the interplay between chronic gastrointestinal (GI) conditions and psychological well-being, particularly regarding healthcare utilization. This study uniquely aggregates various chronic GI disorders, such as inflammatory bowel disease, celiac disease, and eosinophilic esophagitis, to examine their impact on depression and anxiety.

Methods: Utilizing a retrospective observational design, we analyzed data from 34,876 patients admitted to HCA national hospitals from January 2016 to December 2022.
