Objectives: Some proportion of Korean patients with irritable bowel syndrome may have lactose intolerance as the prevalence of lactose intolerance in Korea is very high. This study was undertaken to determine the prevalence of lactose intolerance in Korean adults with the irritable bowel syndrome and the relationship between lactose intolerance and history of milk intolerance. Methods: 50 patients with the irritable bowel syndrome were tested for lactose intolerance by measurement of breath hydrogen excretion after ingestion of 50g of lactose. Results: 33 of the 50 patients (66%) had lactose intolerance. Twenty of 33 subjects with a history of milk intolerance had positive lactose hydrogen breath test, and thirteen of 17 subjects without it had also positive result. Therefore, there was no significant relationship between lactose intolerance and history of milk intolerance (p>0.05). Conclusion: Korean adults with irritable bowel syndrome need to be screened by lactose hydrogen breath test.
