Ulcerative Colitis is one of two major inflammatory bowel diseases, along with Crohn’s Disease, and according to the Center for Disease Control and Prevention (aka the CDC), about 3 million adults in America report having one or the other. Ulcerative Colitis is a chronic disease that is associated with a multitude of abdominal symptoms. While it is often times a life-long disease, there are ways to better manage it. Which is why patient education on what Ulcerative Colitis and inflammatory bowel disease is, its causes, symptoms, and treatment/management is so important.
What is Ulcerative Colitis?
To fully understand what Ulcerative Colitis is, we must first talk about Inflammatory Bowel Disease (aka IBD). IBD is pretty much what the name entails. Inflammation of the gastrointestinal (aka GI) tract that is chronic and can actually lead to internal GI damage if not managed and treated appropriately. IBD is broken into two major conditions primarily depending on the location of the inflammation; Crohn’s Disease and Ulcerative Colitis.
Now that we know what IBD is, we can take a closer look at what Ulcerative Colitis is. The most distinctive difference between Crohn’s Disease and Ulcerative Colitis like previously stated is the location. With Ulcerative Colitis, the inflammation can be found in the large intestine and/or the rectum. On the other hand, Crohn’s Disease can be anywhere in the GI tract. Starting from the mouth and ending at the anus.
Causes
According the CDC, the exact cause of IBD and therefore Ulcerative Colitis is actually, “unknown, but IBD is the result of a weakened immune system.” Likely causes of a weakened immune system can be contributed to environmental triggers like bacterial or viral infections. But there may also be a genetic connection, as “someone with a family history of IBD is more likely to develop this inappropriate immune response.”
Symptoms
Symptoms of Ulcerative Colitis (aka UC) can be divided into two sections: those of IBD, and those more specific to UC. Let’s take a look at IBD symptoms as defined by the CDC first:
- Persistent diarrhea
- Abdominal pain
- Rectal bleeding and bloody stools
- Weight loss
- Fatigue
Now that we know common IBD symptoms, we can take a deeper dive into Ulcerative Colitis specific symptoms. As mentioned, with UC, the location affected is the large intestine/colon and the rectum. However, unlike the patches we see with Crohn’s Disease, Ulcerative Colitis typically damages large, continuous areas of the GI tract. It also only penetrates the innermost lining of the colon rather than the deep penetration seen in Crohn’s Disease. With UC, it tends to work its way up the GI tract, starting at the rectum and working its way up to the large intestine/colon. See the image below provided by the American Gastroenterological Association.
Labs and Imaging
To diagnose Irritable Bowel Disease, but more specifically Ulcerative Colitis, there are multiple labs and imaging studies that can be done. To start with there are blood tests and stool samples that can be collected. With blood tests, we are looking for internal bleeding in the GI tract, indicated by anemia in labs. We are also looking for signs of inflammation that can be seen with high white blood cell (aka WBC) counts and other inflammatory markers. With stool tests, we are looking for other possible causes for the patients symptoms, like bacterial or viral infection or parasites.
As far as imaging goes, we can visualize the lining of the GI tract with a colonoscopy, a thin flexible tube with a camera attached to the end that is inserted in the anus and goes up the GI tract. We can also visualize the abdominal cavity through X-Rays with contrast dye, MRI’s (aka Magnetic Resonance Imaging), and CT (aka Computed Tomography) scans. We are specifically looking for the consistent but superficial inflammation all throughout the GI tract.
Treatment – Medications
Like previously mentioned, there is no cure for Irritable Bowel Disease or Ulcerative Colitis but there are options to help manage the inflammation and ease the symptoms. As far as medications go, there are 5 major choices according to the Americal Gastroenterological Association.
Aminosalicylates
These drugs help, “control inflammation, especially in those who are newly diagnosed with mild symptoms.”
Corticosteriods
These drugs also help control inflammation but only for short term use. They, “are often given in large doses when the disease is at its worst, then lowered as symptoms get under control. They are given to people with moderate to severe symptoms.”
Immunosuppressants
These drugs take a while to begin seeing therapeutic effects so they are often paired with aminosalicylates or corticosterroids. They work by blocking, “the immune reaction that leads to inflammation, lessening swelling in the gastrointestinal (GI) tract.”
Biologic and Biosilimar Treatments
These drugs, “are used in people with moderate to severe ulcerative colitis who do not respond to other treatments.” They are administered via injection or infusion rather than the previously mentioned treatments that are administered in the pill form.
Treatment – Non-Pharmaceuticals
In severe enough cases, parts of the GI tract are so damaged to the point where they cannot be repaired or saved. In these situations, surgical removal is the only answer. Patients may be left with resectioned intestines and possibly even an ostomy where part of the intestine or ileum is brough through the abdominal wall and an exterior bag is placed to collect the waste product, aka stool.
Patient Education
Patient education and cooperation is key in treating and managing Ulcerative Colitis. By teaching the patient about the disease, they have a better chance of understanding and managing it more independently. While we may not know the exact cause of the disease, we do know about ways to decrease inflammation and help manage the symptoms.
First off, smoking cessation is important as it worsens symptoms and can cause flare-ups. Recommend that your patients stay up to date with their vaccines as having IBD put them at a greater risk for developing infection. Having IBD can also cause bone weakening, so being aware of this and having regular bone density tests are important. Some patients with Irritable Bowel Disease needs more routine testing and additional screening for colorectal cancer and cervical cancer. It is important to remember that these patients are going to have a difficult time eating and digesting food which could put them at a higher risk for anxiety, for example when they need to run to the bathroom at unpredicted times, or depression. Because of this, talking about mental health with these patients along with physical health is vital.
If Left Untreated…
If left untreated, Ulcerative Colitis can cause even more severe symptoms as the inflammation increases. It can penetrate deeper into the walls of the GI tract and result in something called toxic megacolon which requires surgery and can be deadly. It can also lead to a mirad of other health concerns, some of them previously mentioned, such as pain, fatigue, infection, osteoporosis, colorectal cancer, cervical cancer, as well as mental health issues. Because of this, it is so important to educate our patients on recognition, treatment, and preventative management.
