Do I Have Ulcerative Colitis—What if Your Gut Has Been Trying to Tell You?

Ulcerative colitis (UC) is a type of inflammatory bowel disease (IBD) that causes long-lasting inflammation and ulcers in the inner lining of your large intestine (colon) and rectum. It can develop at any age but often strikes between 15 and 30 years. If you’ve been experiencing digestive upsets that just don’t seem to go away, your gut may indeed be sending you warning signs.

Common Signs and Symptoms

Not every stomach ache means ulcerative colitis. Still, watch for symptoms that last more than a few weeks or get steadily worse. Key warning signs include:

• Persistent diarrhea
• Blood or pus in your stool
• Urgency or inability to hold bowel movements
• Abdominal cramps and pain, often on the lower left side
• Frequent gas and bloating
• Unexplained weight loss
• Ongoing fatigue or low energy

You might also notice symptoms outside your gut:

• Joint pain or swelling (arthritis)
• Mouth sores
• Skin rashes or red bumps (erythema nodosum)
• Eye inflammation (iritis or uveitis)

These extraintestinal signs occur in up to 30% of people with UC and reflect how inflammation can affect your entire body.

When to Worry

Some UC symptoms overlap with less serious conditions like irritable bowel syndrome (IBS) or an intestinal infection. Yet certain red-flag signs require prompt medical attention:

• Heavy rectal bleeding
• High fever (over 100.4°F)
• Severe, constant abdominal pain
• Signs of dehydration (dizziness, dark urine)
• Rapid weight loss (more than 5% of body weight in a month)

If you experience any of these, seek medical care right away.

How Ulcerative Colitis Is Diagnosed

Diagnosing UC involves ruling out infections, other IBD (like Crohn’s disease), and non-inflammatory causes. Your doctor may recommend:

1. Blood tests
   • Look for anemia (low red blood cells) and markers of inflammation (C-reactive protein, ESR).
2. Stool studies
   • Rule out infections (bacteria, parasites) and detect blood.
3. Colonoscopy with biopsy
   • A flexible camera examines your colon lining; tissue samples confirm inflammation type and extent.
4. Imaging (CT or MRI)
   • Sometimes used to assess severe disease or complications outside the colon.

According to the American College of Gastroenterology (Rubin et al., 2019), a clear diagnosis is key to starting the right treatment and avoiding complications.

Understanding Severity and Extent

UC severity guides treatment choices:

• Mild
  • <4 bowel movements per day
  • Minimal bleeding
  • Normal energy levels
• Moderate
  • 4–6 bowel movements per day
  • Noticeable bleeding and systemic signs (fever, anemia)
• Severe
  • ≥6 bloody bowel movements per day
  • High fever, rapid heart rate, significant anemia, dehydration

The extent refers to how much of your colon is affected:

• Proctitis (rectum only)
• Left-sided colitis (up to splenic flexure)
• Pancolitis (entire colon)

Your care plan will depend on both how severe and how extensive your disease is.

Treatment Options

Goal: achieve and maintain remission, improve quality of life, and avoid surgery.

1. 5-Aminosalicylic acids (5-ASAs)
   • First-line for mild to moderate UC (sulfasalazine, mesalamine).
   • Reduces inflammation in the colon lining.
2. Corticosteroids
   • For short-term control of moderate to severe flares.
   • Not for long-term use due to side effects.
3. Immunomodulators
   • Azathioprine, 6-mercaptopurine: maintain remission when 5-ASAs aren’t enough.
4. Biologics
   • TNF inhibitors (infliximab), integrin receptor antagonists (vedolizumab), IL-12/23 inhibitors (ustekinumab).
   • Reserved for moderate to severe disease or steroid-dependent cases.
5. Small-molecule drugs
   • JAK inhibitors (tofacitinib) for certain adults with moderate to severe UC.
6. Nutritional support
   • No single “UC diet,” but well-balanced meals, hydration, and small frequent feedings help.
7. Surgery
   • Colectomy (removal of the colon) can be curative.
   • Considered when medical therapy fails or complications occur (toxic megacolon, severe bleeding).

Living with Ulcerative Colitis

• Track your symptoms, diet, and medication side effects.
• Manage stress through exercise, mindfulness, or counseling—stress can worsen flares.
• Stay up to date on vaccines (flu, pneumonia) since some treatments affect your immune system.
• Join a support group or online community; sharing experiences can help you cope.

Differentiating UC from Other Conditions

• Irritable Bowel Syndrome (IBS): pain improves after bowel movements, no bleeding or inflammation.
• Crohn’s Disease: can affect any part of the digestive tract, deeper “skip lesions,” and fistulas.
• Infections: usually shorter duration, often linked to contaminated food or travel.
• Celiac Disease: triggered by gluten, diagnosed by blood tests and intestinal biopsy.

Self-Assessment and Next Steps

If you’ve had ongoing digestive pain, frequent trips to the bathroom, or any red-flag symptoms, you deserve clarity. Consider a free, online symptom check for to gather more information about what you’re experiencing.

When to Speak to a Doctor

Only a healthcare professional can confirm ulcerative colitis or rule out other serious issues. Reach out if you:

• See blood in your stool repeatedly
• Can’t keep food or fluids down
• Feel dizzy, faint, or unusually weak
• Have unintentional weight loss

Always treat potential life-threatening or serious concerns as urgent. Prompt medical evaluation saves lives.

Take your gut’s signals seriously—early diagnosis and proper treatment make a big difference in managing ulcerative colitis. If you suspect UC or any other serious condition, speak to a doctor without delay.
