Resumo

Objectives: To evaluate the effects of olive oil and flaxseed oil compared with mineral oil for the treatment of constipation in patients undergoing hemodialysis. Methods: A 4-week, double-blind, randomized, and controlled trial was conducted. Fifty constipated patients (29% male, 51 +/- 12 years) diagnosed by the Rome III criteria were randomly assigned to receive mineral oil (control group; n 5 17), olive oil (n = 16), or flaxseed oil (n = 17). The initial oil dose was 4 mL/day, and adjustments during the follow-up could be made as needed. The impact of the intervention was assessed by the Rome III criteria scores. Results: The most frequent symptoms of constipation evaluated by the Roma III criteria at baseline were comparable among the groups and included ``incomplete evacuation{''} (92%), ``lumpy or hard stools,{''} (72%) and ``anorectal obstruction'' (70%). The Rome III score improved significantly in patients receiving mineral oil (10.5 +/- 5.0 to 4.1 +/- 4.0; P < .01), olive oil (10.3 +/- 4.2 to 3.2 +/- 3.8; P = .01), and flaxseed oil (9.6 +/- 4.2 to 6.0 +/- 5.1; P < .01), with no significant group-by-time interaction (P = .15). The scores of 5 from 6 constipation symptoms reduced similarly in the mineral oil and olive oil groups, whereas only the frequency of evacuation and the consistency of stools improved in the flaxseed oil group. Conclusions: We demonstrated that the daily use of olive oil or flaxseed oil was as effective as mineral oil in the treatment of constipation in patients undergoing hemodialysis.
