Can Constipation Cause a Fever? When to Go to Urgent Care

A young women sits on the edge of her bed. She clutches her abdomen and leans forward as if in pain.

Constipation is when a person passes less than three bowel movements a week or has difficult or hard bowel movements. Dehydration is a typical culprit of constipation, but it can also result from insufficient fiber, physical inactivity, a side effect of certain medications, or something a little more problematic, especially when accompanied by a fever.

If you’re wondering, “Can constipation cause a fever,” you’ll be happy to know that while the two can happen at the same time, constipation does not cause a fever.

Constipation and fever: What to know

If you’re experiencing symptoms of constipation and have a fever over 101 degrees Fahrenheit, it’s time to check in with your doctor or visit your local urgent care center. These two symptoms together usually mean there’s a severe underlying medical issue, like diverticulitis or appendicitis.


Diverticula are small, bulging pouches that can form along the colon. Many people can have them without symptoms, but sometimes bacteria can get trapped inside these pouches and lead to infection and inflammation. In addition to fever, diverticulitis can cause severe or sudden pain on the left side of your abdomen as well as nausea and vomiting. Pain can be mild at first and increase over time. Diverticulitis requires treatment with a course of antibiotics, so if you have constipation as well as unexplained fever, go to your primary care doctor or visit your local urgent care as soon as possible.


Appendicitis is an inflammation of the appendix, a pouch on the colon that has no known purpose. It begins with pain near the belly button and then moves to the right side. Appendicitis is often accompanied by nausea, vomiting, poor appetite, fever, and chills as well.
