Dietary factors in the aetiology and treatment of constipation during pregnancy.

Abstract

Using a 7-day weighed-intake method, dietary factors implicated in the aetiology of constipation were examined by comparison between the nutrient intakes of nine women with constipation in the third trimester of pregnancy who had not altered their diets, and a matched group of nine women who had not suffered constipation at any time during pregnancy. No significant differences were found for intakes of major nutrients, including dietary fibre, between the constipated and non-constipated groups, indicating that inappropriate diets do not appear to be the primary cause of constipation during pregnancy. The nutrient intakes of 40 women with constipation in the third trimester of pregnancy were examined to assess dietary changes made in attempts to treat constipation. No difference in intakes of dietary fibre were found between those who claimed to have increase their intakes, and those who had not altered their diets. Both were well below the level of dietary fibre intake known to be successful in treating constipation.
