Constipation Management

First-Line Therapy

Fiber supplements, particularly psyllium, are recommended as first-line therapy for constipation due to their efficacy and safety profile, according to the American Gastroenterological Association 1
A dietary assessment should be conducted to determine current fiber intake before supplementation, as recommended by the American Gastroenterological Association 1
Patients should increase dietary fiber intake to approximately 30g/day, ensure adequate fluid intake, allow sufficient time for bowel movements, and use relaxation techniques to avoid straining, as recommended by the American College of Gastroenterology and the American Gastroenterological Association 2

Polyethylene glycol (PEG) is recommended with strong evidence for constipation management, according to the American Gastroenterological Association 1
PEG (17g/day) offers an efficacious and tolerable solution with a good safety profile, particularly for elderly patients, as recommended by the European Society for Medical Oncology 3
Polyethylene glycol (PEG) is safe during pregnancy and effective for constipation relief, but may cause maternal bloating, with a recommended dose of 17g daily mixed with 8 oz of liquid, as recommended by the European Society for Medical Oncology and the American Gastroenterological Association 3, 2

For pregnancy-related constipation, the American Gastroenterological Association recommends dietary fiber, bulk-forming agents like psyllium, and osmotic laxatives such as polyethylene glycol (PEG) or lactulose as the safest and most effective first-line treatments 2
Psyllium husk is safe during pregnancy due to minimal systemic absorption and improves stool viscosity and transit time, with a recommended daily dose of 6.8-10.8g with 8-10 oz fluid, as recommended by multiple sources 4, 1, 2
Lactulose is safe during pregnancy, but may cause maternal bloating, as recommended by the American Gastroenterological Association 2
Stimulant laxatives should generally be avoided during pregnancy due to conflicting safety data, but may be considered in the second and third trimesters for refractory cases only, as recommended by the American Gastroenterological Association 2, 5, 3
For elderly patients, liquid paraffin should be avoided in bed-bound patients due to the risk of aspiration, according to the European Society for Medical Oncology 3

Bulk laxatives such as psyllium are not recommended for opioid-induced constipation, as stated by the European Society for Medical Oncology 3
Osmotic or stimulant laxatives are generally preferred for opioid-induced constipation, according to the European Society for Medical Oncology 3

Evaluation should include detailed history of bowel movement frequency, consistency, pain, and bleeding, and patients should be aware of potential side effects such as flatulence, bloating, and abdominal discomfort, as recommended by multiple sources 4, 1, 2
The goal of treatment is to improve bowel movements, stool consistency, and reduce laxative use, as recommended by the American Gastroenterological Association and the American College of Gastroenterology 4, 6, 7, 8, 2
