Many people with Crohn’s disease complain about pain in their backs, or around their kidney regions. While it’s difficult to pinpoint the exact cause of pain due to individual circumstances, there are a number of common reasons that Crohn’s sufferers experience pain. Most of them are directly related to complications in the kidneys that are caused by the Crohn’s condition.

The following are some of the kidney-related disorders that often stem from Crohn’s. These disorders may be the cause of any back and kidney pain that you are experiencing.

Kidney Stones

Kidney stones are a health problem often encountered by people who suffer from Crohn’s. The condition is caused by malabsorption in the gut, in particular the malabsorption of fat, which then binds to calcium, leaving oxalate (a type of salt) free to be absorbed and deposited into the kidney. In the kidney, that fat-calcium compound then turns to stone. Crohn’s sufferers also often get kidney stones due to dehydration. Kidney stones are a leading cause of pain in people with Crohn’s.

Uric Acid Stones

Uric acid stones are kidney stones that are made of pure uric acid. Crohn’s sufferers frequently get these types of stones because they have extremely concentrated urine that gets absorbed into the injured colon. These kidney stones often do not pass right away, which can lead to severe pain.


This condition is an anatomical complication that stems directly from Crohn’s disease and other irritable bowel diseases. In hydronephrosis, the ureters (the tubes connecting the kidney to the bladder) are obstructed. This problem typically occurs with the right kidney because it is the one closest to the lower part of the small intestine (the most common site of Crohn’s disease). Hydronephrosis causes tremendous pain in many people who experience the condition.

These are some of the most common links between Crohn’s disease and kidney pain. If you experience any pain, it’s essential that you speak with a Crohn’s Doctor to determine the exact cause. Along with a medical professional, you can begin to manage your lifestyle so that healing comes and pain disappears.
