Chronic gastrointestinal symptoms in hemodialysis patients

Gastrointestinal disorders occur frequently in dialysis patients. Few data are available on the prevalence of symptoms originating from the gastrointestinal tract in this group of patients. Our aim was to obtain data on the prevalence of chronic gastrointestinal symptoms in patients undergoing hemodialysis.

All 109 patients of our dialysis unit were given a questionnaire to complete which was previously validated and designed to measure the occurrence of gastrointestinal, and some general symptoms during the preceding year. 105 subjects responded (96% response rate).

79% of dialysis patients had at least one of the following chronic gastrointestinal symptoms: Esophageal symptoms were reported in 21% abdominal pain in 28% and dyspeptic symptoms in 48%. The irritable bowel syndrome was diagnosed in 12 patients (11%), 40% had chronic constipation and 24% had chronic diarrhoea. Colonic pain was described in 20% of patients. Frequent general symptoms (such as weakness, headaches, insomnia and fatigue) were described in up to 51%, and patients were severely bothered by symptoms in up to 33% of cases.

Although patients on hemodialysis generally report a good quality of life, the prevalence of gastrointestinal symptoms and of general symptoms is high and many dialysis patients consider these symptoms to cause major impairment of daily life.
