Overview
Chronic constipation treatment includes both behavioral and pharmacological interventions. Behavioral management mostly consists of life style and dietary modification, while pharmacological interventions are mostly based on laxatives. Increasing physical activity is postulated to improve constipation and colonic transit time in patients with constipation. The most important behavioral treatment for constipation is biofeedback, consisting of teaching the patients how to use their abdominal and pelvic muscles during defecation. Probiotics are live microorganism spores that are given orally to improve the gastrointestinal tract function. Recently, use of probiotics in food industry is growing. Bifidobacterium and Lactobacillus are most studied organisms as probiotics.
Medical Therapy
- General principles of medical therapy in patients with chronic constipation are as following:[1]

Chronic constipation management
- Chronic constipation treatment includes both behavioral and pharmacological interventions.
- Behavioral management mostly consists of life style and dietary modification, while pharmacological interventions are mostly based on laxatives.
Lifestyle modification
- Increasing physical activity is postulated to improve constipation and colonic transit time in patients with constipation.[2]
- Moderate physical exercise as much as 32 min per day have shown significant improvement of quality of life but no significant decrease in laxative need for treatment.[3]
- Moderate to vigorous training (20-60 min, 3-5 times per week) revealed significant improvement in constipation symptoms in patients with irritable bowel syndrome (IBS).[4]
Dietary interventions
- Fiber supplementation is the main primary therapeutic intervention for every patients with constipation.
- The polysaccharide fibers are the agents that increase the weight of stool and and improve the stool consistency by absorbing and retaining water.[5]
- The most common used bulking organic polysaccharide in Canada is Psyllium.
- Psyllium and lactulose is found to significantly decrease colonic transit and improve stool consistency.[6][7]
Biofeedback treatment
- The most important behavioral treatment for constipation is biofeedback, consisting of teaching the patients how to use their abdominal and pelvic muscles during defecation.
- During the biofeedback, patients receive feedback on their abdominal and pelvic floor muscle contractions recording by means of surface electromyography (EMG).
- Based on the biofeedback, patients are taught how to increase intra-abdominal pressure and also relax their pelvic floor muscles to have a coordinated evacuation.[1]
- Regarding the outcomes, the biofeedback behavioral therapy is the choice treatment for functional defecation disorder.[8]
Pharmacological intervention
