Treatment for Constipation Lasting 1 Week

Initial Approach

The American Gastroenterological Association recommends increasing fluid intake, particularly for those with low fluid consumption, to help manage constipation 1, 4
Increasing dietary fiber is recommended if the patient has adequate fluid intake and physical activity, as suggested by the National Comprehensive Cancer Network 5, 4
Exercise is also recommended, if appropriate for the patient's condition, to help alleviate constipation symptoms 5, 4
Polyethylene glycol (PEG) is recommended as first-line pharmacological treatment, with a dose of 17g mixed in 8 ounces of water once daily, due to its proven efficacy in increasing bowel movements and providing global symptom relief 1, 2, 3
PEG provides global relief of symptoms in a significant proportion of patients 5

If PEG is unavailable or ineffective, fiber supplements such as psyllium can be used, with a recommendation to take with 8-10 ounces of fluid 3, 6
Stimulant laxatives like bisacodyl can be used, with a goal of one non-forced bowel movement every 1-2 days, and are a good option for occasional use or rescue therapy 5, 4, 6
Osmotic laxatives such as magnesium citrate can be used if above options fail, with a dose of 8 oz daily, but magnesium products should be avoided in patients with renal insufficiency 6

If constipation persists despite above measures, it is essential to rule out impaction and obstruction, and consider glycerine suppository with or without mineral oil retention enema, or bisacodyl suppository 5, 4
Tap water enema until clear can be used for impaction 5, 4

The American Gastroenterological Association recommends avoiding excessive use of stimulant laxatives, as they should not be used for more than one week without medical supervision, and avoiding magnesium-based products in patients with renal insufficiency due to risk of hypermagnesemia 6
Ensuring adequate hydration when using fiber supplements is crucial to prevent worsening of constipation, as recommended by the American Gastroenterological Association 1, 2, 6
A treatment algorithm is suggested, starting with PEG 17g daily, adding a stimulant laxative if insufficient response, and considering suppositories or enemas if still inadequate response 1, 2, 3, 5, 4, 6
