Causes of constipation after colonoscopy.
During the preparation for your colonoscopy, your colon needs to be emptied. This “emptying” process may cause a 1-2 days delay in your first bowel movement.
But a” delayed bowel movement” is different from constipation. With delayed bowel movement, you can’t poop because of not enough colon contents to poop after colonoscopy.
But with Constipation, you can’t poop after colonoscopy because your stool is hard, or you have a problem
With your colon motility.
A delay in your Bowel movement after colonoscopy for one or two days is common and is considered normal. this is because your colon needs to refill itself with fecal material again after colon prep.
But prolonged constipation with hard stool randy occurs, and it affects less than 2% of people undergoing colonoscopy (ref).
constipation after colonoscopy can be due to:
(1) Lack of activity or Exercise.
Staying in bed or not being active during the first day or few days after colonoscopy is a common cause of getting constipation after colonoscopy (ref).
Surgeons usually advise their patients to move after operations especially if the operation is in the abdomen this is because physical activity emulates the motility of your colon
(2) Not drinking enough fluids.
The colon preparation process may be exhausting for you. Many people fail to obtain enough amounts of fluid before and after colonoscopy.
Not drinking enough water leads to the hardening of your stool (constipation) after colonoscopy.
You can drink water or any type of fluids including hot beverages, fruit juice, or any other fluids that you can tolerate.
(3) Not enough fiber in the diet.
Faulty diet habits after colonoscopy can also lead to constipation. Eating foods that lack fibers such as high fat, fried, or fast food can negatively affect your Bowel movement after colonoscopy (ref).
Lack of fiber-rich foods such as fruits, vegetables, whole grain is one of the main reasons why people get constipated.
(4) Ignoring the urge to poop
Sometimes you (subconsciously) ignore the urge to poop because of:
- Being tired or dizzy after sedation during colonoscopy.
- Problems in your colon and rectum such as fissures or masses causing painful bowel movements.
Ignoring the urge to poop after colonoscopy will make your colon absorb more water. And as a result, your poop becomes harder to pass and you’ll get constipated after colonoscopy(ref).
(5) Not eating “enough”.
Not only the type of food but also the amount of food you eat can contribute to post co locos copy constipation. Being bloated or having stomach pain after colonoscopy is common. And this may prevent you from eating at all or eating enough amounts after colonoscopy.
As a result, you won’t be able to “refill “your empty colon after colonoscopy.
So eating the right type and the right amount of food is critical to prevent constipation post colonoscopy.
There is no need for “overeating”, just eat the average amounts you can tolerate.
(6) Irritable bowel syndrome.
You can experience constipation after colonoscopy if you’re already an IBS sufferer.
This is more common with the constipation-predominant or the mixed type of IBS.
Also, taking medications for IBS-diarrhea after colonoscopy (such as Immodium) can cause constipation.
(7) Having anal or rectal problems or procedures.
Anal or rectal pain can lead to constipation (ref). Any pre-existing and or rectal problems such as anal fissure, rectal masses, or inflamed hemorrhoids will contribute to constipation after colonoscopy. Also, the colonoscopy procedure itself can aggravate pain from your existing condition.
Anal or rectal pain can occur due to some procedures done during the colonoscopy such as:
- Taking a biopsy from the anus or rectum.
- A hemorrhoid operation by colonoscopy.
- Removal of a mass or polyp from the anorectum.
(8) Being a female or older in age

- Being female increases your odds of getting post colonoscopy constipation (ref).
- Also, older ages (especially if you’re more than 60) are a risk factor for getting constipation.
- Other factors such as
- Diabetes Mellitus
- Thyroid gland diseases.
