It's easy to dismiss a stomach cramp or a bout of diarrhea as just one of those things. We all get them, right? But what if those aren't isolated incidents? What if they're persistent, severe, and frankly, alarming? If you're experiencing frequent, intense cramping and bloody diarrhea, it's time to pay attention. It could be a sign of ulcerative colitis (UC).
Ulcerative colitis is a chronic disease affecting the large intestine, or colon. While we don't yet know exactly what causes it or how to cure it, the good news is that getting a diagnosis sooner rather than later means you can start managing the symptoms and improving your quality of life. But first, you need to get tested.
What to Expect When You See Your Doctor
Your doctor will want to get a complete picture of your health. This means they'll ask about your medical history, and any family history of ulcerative colitis, Crohn's disease (both are types of inflammatory bowel disease, or IBD), or other autoimmune conditions could be really helpful information to share. It's also a smart move to bring a list of everything you're taking – prescription medications, over-the-counter remedies, supplements, even herbal teas. It all matters.
Then comes the physical exam. Your doctor will likely check your vital signs – blood pressure, heart rate, temperature. They might listen to your abdomen with a stethoscope, gently press on your belly to check for tenderness, and perhaps perform a digital rectal exam to look for any signs of bleeding.
The Diagnostic Toolkit: Tests to Pinpoint the Cause
To figure out if UC is the culprit, doctors have a range of tests at their disposal. It often takes a series of them to rule out other possibilities, which can feel like a lot, but it's all part of the process.
-
Blood and Stool Tests: These are often the first steps. A blood test can reveal anemia, a common symptom of UC where your body doesn't have enough healthy red blood cells to carry oxygen. It can also flag signs of infection, an increase in white blood cells (indicating inflammation), low albumin levels, and elevated C-reactive protein – all clues that your body is fighting something.
Stool tests are crucial too, primarily to rule out infections that can mimic UC symptoms.
-
Endoscopy: Looking Inside: This is where doctors get a direct look at your intestinal lining. The two main types are:
-
Sigmoidoscopy: This is a shorter procedure, usually taking 15-20 minutes. A flexible tube called a sigmoidoscope, equipped with a light and camera, is gently inserted into the rectum to examine the lower part of the colon. You might be given medication to help you relax. To ensure a clear view, you'll likely be asked to drink a laxative the night before.
-
Colonoscopy: This is a more comprehensive exam that looks at the entire colon. It's an outpatient procedure, typically lasting 30 minutes to an hour. Similar to a sigmoidoscopy, bowel preparation with a laxative the night before is essential. During the colonoscopy, a longer, flexible tube called a colonoscope is used. This procedure allows doctors to not only see inflammation and bleeding but also to take a biopsy (a small tissue sample) if needed. This is vital for determining the severity of UC and distinguishing it from Crohn's disease.
For both procedures, if you receive a sedative, you'll need someone to drive you home afterward.

X-ray and CT Scan: Sometimes, imaging tests like X-rays are used to rule out other serious issues, such as a perforated colon. A CT scan can be helpful in detecting complications of UC or identifying other conditions that might present with similar symptoms.
It's a journey, and these tests are the map. The sooner you start, the sooner you can understand what's happening and begin to feel better.
