Symptoms, Treatments, and Differences of Crohn's and Ulcerative Colitis

Updated on October 23, 2019

Angela was diagnosed with ulcerative colitis17. At 20, she had a colectomy, where they removed her colon.


Is IBS an IBD? What's the Difference?

An IBD stands for inflammatory bowel disease, whereas IBS stands for irritable bowel syndrome. There are only two IBDs, ulcerative colitis, and Crohn's disease. The fundamental difference between IBD and IBS is that Crohn's and ulcerative colitis usually result in ulcerations, whereas IBS does not.

One reason IBD is confused with IBS is that irritable bowel is often called spastic colitis, as well as colitis. Coincidentally, both IBDs can be referred to as just colitis since that merely means inflammation of the colon. Often at the earlier phases of an IBD, a doctor may misdiagnose as irritable bowel syndrome. One of the most significant predictors that it might be something else is if you see blood in your stool. Keep in mind hemorrhoids can also cause blood in the stool. Hemorrhoids are often caused by frequent bowel movements, which is characteristic of both IBDs and IBS. Therefore, do not assume you have something more severe at the presence of blood, instead seek medical attention to rule out hemorrhoids.

Does Stress Cause Inflammatory Bowel Disease?

Contrary to popular belief, emotional stress is not a cause for Inflammatory Bowel Diseases. On the other hand, stress can trigger a flare-up, the same way in which all diseases can flare during a time of stress. Many myths are surrounding IBD's as well.

Due to the similarities of the diseases, they are often confused in both diagnosis and symptoms. The main difference is ulcerative colitis affects the colon, whereas Crohn's can target any part of your digestive system from the mouth to the anus, which does not mean that Crohn's is a more severe disease. Someone with Crohn's may have a more mild case than someone with ulcerative colitis; it depends on the severity of the symptoms in the individual.

Unlike Crohn's disease, there is a "cure" for ulcerative colitis. I use quotes because I have been "cured" of ulcerative colitis. Unfortunately, there are lifelong ramifications to being cured since the only real cure is a full removal of your large intestine, which should not be a decision to be taken lightly, as I have met numerous people who have regretted their decision. Without my colon, I had five to eight bowel movements for the first five years after, and now have three to five bowel movements a day. Diarrhea is experienced differently without a colon. Also, there were many complications that I experienced afterward, such as blockage, abscesses, and pulmonary embolism as a result of surgery. There are other complications, as well. Yet, I am personally glad to be cured as I had nearly lost my life prior.

Both IBDs have inherited diseases. Twenty percent of people with UC have one other close relative with another IBD disorder, either Crohn's or UC itself. Since the diseases are so closely related, a person with ulcerative colitis may have a relative who has Crohn's. Both run on both sides of my family. At the current time, there has not been a gene identified as the IBD carrier; therefore, there is not a test to see if you will get the disease.

Not only can Crohn's affect a more significant portion of the digestive tract, but it also affects more layers of the colon wall. Ulcerative colitis only inflames the innermost lining, whereas Crohn's affects several layers of the intestinal wall.


How is Ulcerative Colitis and Crohn's Diagnosed?

The first step in diagnosing is to rule out more common ailments. Stool tests are performed to eliminate possible infectious diseases as the cause. They may also do a CT scan on the abdomen.

Once all other possibilities are ruled out, your gastroenterologist may choose one of two procedures- sigmoidoscopy or colonoscopy. These are both relatively painless, dependent on the degree of the disease. The first is sigmoidoscopy, where they check only the rectum and lower colon area. The second is a test of the entire colon called a colonoscopy, which allows the physician to take biopsies of the colon lining. The patient is awake during this procedure, but due to the nature of the medications, there is an amnesic effect. Therefore, you will not remember much of the test.

They may also do an endoscopy, which is a tube you swallow, that shows the upper portion of the digestive system, which is more significant in diagnosing Crohn's.


Many of the symptoms are very similar. They include, but not limited to:

  • abdominal pain and cramping
  • bloating
  • blood in the stool
  • loss of appetite
  • mucus in the stool
  • persistent diarrhea
  • ulceration in the digestive tract

There are also some common non-digestive related symptoms, such as delayed growth in younger children, eye irritations, fever, weight loss, and more severe PMS symptoms. Nausea is more commonly associated with Crohn's, although it is present in more severe cases of UC.

Some of the more unusual symptoms I have experienced, even now after having been cured is getting eye inflammation called episcleritis, as well as joint pain. These can be related to ulcerative colitis.

Are There Treatments for IBDs?

The most common treatment is medication. As stated earlier, UC is theoretically curable. Having gone through the surgery, non-electively, I would not encourage anyone to do it electively unless their symptoms are severe. I am 16 years post-op. Although my digestive system functions normally, there are still things that are atypical about my digestion. In the first few years, my symptoms seemed very similar to a mild case of the disease.

The cure included removing my entire colon except for my rectum, which allowed me to be able to have my ilium reconnected to my rectum so that I could use the bathroom without the use of an ostomy. Due to the severity of the disease and the newness of the surgery at the time, they were unable to do the full surgery in one step. So I did have a six month period where I had an ostomy. In place of a colon, they form a pouch from the bottom portion of your ileum. It is incredible how effective this structure is, but it takes years for it to adjust. During the adjusting time, things are not always easy. The reason it is not encouraged for Crohn's patients is that even if the colon is the only affected area, chances of them getting sick in a different section of the digestive tract is very likely.

Feel free to ask any questions or contact me if you want to talk to someone who has been there. If you think you have the disease, definitely contact your doctor. For the first five years post-op, I ran a website where I had contact with hundreds of people who had the disease. I can tell you very much what it like first-hand, as well as what others experienced. Medically speaking, I'm not qualified; therefore, you must contact a nurse or doctor. I am here for emotional support, not medical advice. I have found that there are amazing nurses (and doctors) out there; find one that is a good fit for you.

      People will take Ulcerative colitis and Chrons as IBS because IBS and IBD have the same symptoms,but these are IBD.IBS is a syndrome, not a disease, it does not lead to colon cancer, and it does not cause bleeding. Ulcerative colitis, however, is a disease, can put patients at risk for colon cancer, and bleeding is a common symptom.

      Wow, this is incredible information. I have friends who suffer from UC and one who suffers from Crohn's, I always though their symptoms were similar. but never knew the difference. You have been generous in sharing your experiences and knowledge with others. I know Crohn's sufferers feel very alone, as do my friends with UC. Congratulations on your nomination!

      Trish, I hope your cases isn't very severe. It's hard to live with. I think the statistic is 20 percent of people who have the disease will have a relative who has the disease. So you are with the majority who don't have other family members who have the disease. Part of the reason they believe it is familial is because there are certain races who have higher prevalence, whereas area where they grew up or lived do not play a large factor. Basically, like many diseases, it can be dormant in several generations, then one person has the gene, but also has the triggers. Many diseases are like that, for instance type one diabetes, rheumatoid arthritis. Just because you have the gene, doesn't mean you will have it, but as you pass it down the generation, they are more likely to have it. Another reason they believe it is hereditary, is because there is a high correlation between identical twins. Which means chances of it being genetic are more likely rather than environmental. That being said, I'm quite certain environment plays a large role in that! My theory anyway.

      I was originally diagnosed with Crohns and later with UC. I haven't inherited it, though. No-one else in my family has it.
