Abstract

Background Gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) are common gastrointestinal disorders that can negatively affect quality of life and healthcare costs. The co-occurrence of these conditions can lead to more complex symptomatology and therapeutic challenges. Therefore, understanding the extent of overlap between GERD and IBS is paramount. This study aims to estimate the overlap between GERD and IBS in Saudi Arabia and its impact on quality of life. Methods Patients with GERD at primary care clinics at King Khalid University Hospital in Riyadh, Saudi Arabia, were the subjects of cross-sectional research. The patients were selected using a simple random sampling technique, and an electronic questionnaire was utilized to collect data. Symptoms of IBS were assessed based on Rome IV criteria, and quality of life was evaluated using the GERD quality of life tool. Results Of the 293 GERD patients, the prevalence of co-occurrence of IBS among GERD patients was 35.8%. The GERD health-related quality of life (GERD- HRQL) scores ranged from 0 to 50, with a median and interquartile range (IQR) of 14 (8.5-20). Those with GERD and IBS had a significantly higher GERD-HRQL score than the patients with GERD alone (11 vs. 9, p-value: 0.049). Furthermore, patients with GERD and IBS had a significantly higher GERD-HRQL score than the patients with IBS alone (15 vs. 11, p-value: 0.001). Of the total participants, 29.4% reported having abdominal pain in the last three months. The majority of the participants (55.6%) reported experiencing abdominal pain one to two times per week, while 22.2% reported experiencing it two to three days per month. Conclusion The high prevalence of IBS co-existence among GERD patients highlights the importance of considering both diseases in clinical practice to improve patient outcomes. The study also found that patients with both GERD and IBS had a significantly lower quality of life than those with GERD or IBS alone.
