Studies have shown that IBS and GERD (gastroesophageal reflux disease) commonly coexist together in patients more often than what had previously been believed.
A study, which was published in the August 2008 edition of Digestive Diseases and Sciences, investigated the relationship between both IBS & GERD.Below is some information on the actual study:
The General Practice Research Database was used to identify patients with a first diagnosis of GERD (n = 6,421) or IBS (n = 2,932). Patients were followed up for 12 months after diagnosis to investigate the incidence of IBS among GERD patients and GERD among IBS patients.
The relative risk (RR) of developing IBS was 3.5 (95% CI: 2.3-5.4) in the GERD cohort compared with the comparison cohort [Note: a relative risk of 1.0 would mean no difference. The RR of developing IBS for these GERD patients was 250% greater than normally expected.] The RR of developing GERD was 2.8 (95% CI: 1.7-4.9) in the IBS cohort compared with the comparison cohort.
Once someone is first diagnosed with IBS or GERD, their risk of developing the other condition significantly increases.
