After reading this article / video, you will understand the differences and similarities between the symptoms of Ulcerative Colitis and Crohn’s Disease.

Abdominal pain, cramping, bloating, mouth sores, joint pain, blood in the stool, and more can all be symptoms of inflammatory bowel disease (IBD). Ulcerative Colitis (U.C.) and Crohn’s are two different types of IBD.

However, the symptoms between U.C. and Crohn’s are slightly different, so we are going to clear up any confusion about the differences in this article.

In this article, we are going to be discussing some of the major differences as well as similarities between the symptoms of Ulcerative Colitis vs Crohn’s Disease.

If you haven’t read my previous article about the differences in Ulcerative Colitis and Crohn’s Disease, make sure you check that out here.

If you have recently been diagnosed with either Ulcerative Colitis or Crohn’s, or you are considering that you might be suffering from Inflammatory Bowel Disease (IBD), in which Ulcerative Colitis and Crohn’s are the top 2 “types” of IBD, then this article will help you know what the common symptoms are between the two different types of IBD.

By knowing this, you will be better able to determine if you or a loved one might be suffering from either of these two conditions.

BOTH: Symptoms of Ulcerative Colitis vs Crohn’s Disease

Let’s first go over which symptoms Ulcerative Colitis and Crohn’s Disease share.

Here are the most common symptoms:

  • Diarrhea / Urgency (feeling like you need to use the bathroom very quickly)
  • Constipation
  • Abdominal pain
  • Cramping
  • Blood in stool
  • Weight loss (due to reduced appetite and reduced ability to absorb nutrients)
  • Fever
  • Fatigue
  • Night sweats
  • Joint pain

Side Notes for Symptoms of Both Ulcerative Colitis and Crohn’s Disease

  • While it can be hard to absorb nutrients in general, usually fats and oils are the most difficult to absorb for IBD. This is because, while carbs and proteins get absorbed high up in the small intestine, fats need to latch onto bile acids and get absorbed in the colon. If you have colon inflammation, this can make it harder to absorb fats.

  • Fatigue is a very common symptom that comes with Ulcerative Colitis and Crohn’s Disease. Many people with IBD are unaware in the beginning how likely it is for them to feel very fatigued on a daily basis. I have another article that addresses fatigue for IBD here that you can check out to learn how to help lower the fatigue.
  • The night sweats can be partially due to bacteria and inflammation, and it can also be due to the anxiety that tends to come with U.C. and Crohn’s.
  • Joint pain can occur with both Crohn’s and U.C., however it is more common with Crohn’s. Both of these conditions tend to cause whole-body inflammation (which is picked up on blood tests as high CRP and ESR, among others). However, as we learned in the previous article, Crohn’s tends to be more of a “whole-body” condition, whereas Ulcerative Colitis usually stays localized to the colon.
  • Keep in mind that you do not have to have all of these symptoms. These are just “potential symptoms” and are the most common ones.

Symptoms of Crohn’s Disease

Now let’s move over to symptoms that are particular to Crohn’s Disease.

Here are the most common ones:

  • Inflammation can appear anywhere in the GI tract (from mouth to rectum)
  • Mouth / Gum / Lip sores
  • Healthy areas in between inflamed spots (“Skip lesions”)
  • More likely to develop fissures (tears) or narrowings (strictures)

Side Notes for Symptoms of Crohn’s Disease

  • Unlike U.C., Crohn’s disease is more likely to become a full gastrointestinal condition, where you can develop esophagus damage, small intestinal issues, and mouth sores.
  • “Skip lesions” in the colon (healthy tissue separated by damaged tissue separated by healthy tissue) is one of the main “signature” findings for Crohn’s during a colonoscopy. U.C. tends to have more continuous damage of the colon.
  • Fissures and strictures can be very problematic if they develop for Crohn’s. For example, a stricture (narrowing) occurs because of continuous damage and healing that leads to scar tissue build up. This can make it very difficult for food to pass through and can even lead to excessive vomiting and nausea.

Symptoms of Ulcerative Colitis

Lastly, let’s list the most common symptoms that are specific to Ulcerative Colitis:

  • Worse rectal bleeding
  • Symptoms are localized to just the colon / rectum
  • No healthy areas between inflamed regions
  • More formation of “ulcers”

Side Notes for Symptoms of Ulcerative Colitis

  • Because of the formation of ulcers, Ulcerative Colitis tends to have worse rectal bleeding. This can mean running to the bathroom 10-20+ times per day due primarily to bleeding.
  • A colonoscopy for U.C. should find more continuous colon damage (not skip lesions like in Crohn’s) and the damage should primarily be in the inner layer of the colon only (compared to all the layers in Crohn’s)
