What people ask
Do Wegovy, Ozempic, Zepbound and Mounjaro cause constipation?
Constipation is a recognized side effect of GLP-1 medicines. An expert review puts it at 4% to 12% in trials, and up to 25% or 35% in some trials of people with obesity. Tell your clinician if it is severe or does not ease.
What helps GLP-1 constipation?
The review advises more water, more fiber and more movement, and says a clinician may suggest a stool softener. NIDDK lists whole grains, beans, fruit, vegetables and nuts as fiber sources. Ask your clinician before adding any product.
How much fiber do you need on a GLP-1?
NIDDK says adults should get 22 to 34 grams of fiber a day, depending on age and sex. Harvard notes most Americans get about 15 grams a day. NIDDK also says to add fiber a little at a time and to drink more liquid as it goes up.
How long does GLP-1 constipation last?
The review says it can start in the first 16 weeks, most often in the first 28 days, and may last longer than other gut effects. One study it cites found a median of 47 days in people with obesity. Everyone differs.
Why can fullness make constipation worse?
The review notes that feeling full after a dose can lead people to drink less water, which may make constipation more likely. Sipping fluids through the day helps. NHS guidance is 6 to 8 cups or glasses of fluid a day.
