Constipation is a common digestive disorder that affects many people and can significantly impact quality of life. Natural remedies such as flaxseed and psyllium offer promising solutions. In this blog post, we highlight two significant studies that have examined the effectiveness of these remedies.

Abstract:
This prospective randomized controlled trial aimed to evaluate the effects of flaxseed supplementation on functional constipation and quality of life in adult men and women in China. 90 subjects with functional constipation diagnosed according to the Rome IV criteria were included. The subjects were randomly divided into two groups: one group received 50 g/day of flaxseed meal with meals (n=60), the other group received 15 ml/day of lactulose solution on an empty stomach (n=30) for 4 weeks.
Methods and study design:
The primary outcomes included Wexner constipation scores, stool consistency according to the Bristol Stool Form Scale, and bowel habits (frequency of bowel movements per week, time spent defecating). The secondary endpoint was change in patient's rating of quality of life for constipation.
Results of the study:
After 4 weeks, both groups showed significant improvements in bowel habits:
- Wexner constipation score: The mean score decreased from 14 to 6.5 in the flaxseed group and from 15 to 9 in the lactulose group (p<0.001 for both groups).
- Stool frequency: The mean stool frequency per week increased significantly (from 2 to 7 in the flaxseed group and from 2 to 6 in the lactulose group, p<0.001 for both groups).
- Quality of life: The quality of life score decreased significantly (-1.34 for flaxseed and -0.66 for lactulose; p<0.001 for both groups).
Conclusions:
Flaxseed flour is slightly more effective than lactulose in increasing stool frequency and improves the quality of life of individuals with chronic functional constipation in the Chinese population.
Study 2: The superiority of psyllium over sodium docusate in the treatment of chronic constipation
Title: Psyllium is superior to docusate sodium for treatment of chronic constipation

Journal: Alimentary Pharmacology & Therapeutics
Date: 1998
DOI: 10.1046/j.1365-2036.1998.00336.x
Abstract:
This multicenter, randomized, double-blind, parallel design study included 170 subjects with chronic idiopathic constipation. Participants underwent a 2-week baseline phase (placebo), followed by a 2-week treatment phase. During the treatment phase, psyllium (5.1 g bd) plus docusate placebo with sodium docusate (100 mg bd) plus psyllium placebo. Stools were collected and evaluated.
Methods and study design:
The subjects were randomly divided into two groups: one group received 5.1 g of psyllium twice daily (n=85), the other group received 100 mg of sodium docusate twice daily (n=85) for a period of 2 weeks. The study phase included a 2-week baseline phase (placebo) and a 2-week treatment phase.
results of the study
- Stool water content: Psyllium increased stool water content significantly more than sodium docusate (psyllium 2.33% vs. docusate 0.01%, P = 0.007).
- Total stool output: Psyllium increased total stool output (psyllium 359.9 g/week vs. docusate 271.9 g/week; P = 0.005).
- Stool frequency: Psyllium resulted in higher stool frequency (3.5 bowel movements/week) compared to sodium docusate (2.9 bowel movements/week) at treatment week 2 (P = 0.02).
Conclusions:
Psyllium is superior to sodium docusate in softening stool by increasing stool water content and demonstrates greater overall laxative efficacy in subjects with chronic idiopathic constipation.
