Ulcerative colitis symptoms most commonly include bloody diarrhea, abdominal cramping, an urgent need to pass stool, and fatigue. This chronic inflammatory bowel disease affects the lining of the colon and rectum. Symptoms often come and go in flare-ups, ranging from mild to severe. Recognising the early signs helps you get timely treatment and avoid complications. In this guide, we explain the key ulcerative colitis symptoms, other warning signs, causes, complications, and how specialists diagnose and treat it. Read on to learn what to watch for and when to see a doctor.
What Is Ulcerative Colitis?
Ulcerative colitis is a chronic inflammatory bowel disease that causes inflammation and ulcers in the lining of the colon and rectum. It is a lifelong condition marked by flare-ups and periods of remission.
Unlike Crohn's disease, it affects only the large intestine. Symptoms depend on how much of the colon is involved.
Key features include:
- Continuous inflammation of the colon lining
- Affects rectum and large intestine only
- Alternates between flare-ups and remission
- Can begin at any age
- Ranges from mild to severe

1. Bloody or Mucus-Filled Diarrhea
Bloody diarrhea is the most common and telling sign of ulcerative colitis. The inflamed colon lining bleeds and produces excess mucus.
Stools may be loose, frequent, and mixed with blood or pus. This can happen many times a day during a flare.
You may notice:
- Blood or clots in the stool
- Mucus or pus with bowel movements
- Frequent, loose stools
- Diarrhea that disturbs sleep
- Persistent watery motions

2. Abdominal Pain and Cramping
Abdominal pain and cramping are common as inflammation irritates the colon. The discomfort is often felt on the left side or lower abdomen.
Cramps may ease slightly after a bowel movement. Pain often worsens during active flare-ups.
Typical patterns include:
- Lower or left-sided abdominal pain
- Cramping before bowel movements
- Bloating and gas
- Discomfort that flares and settles
- Tenderness in the belly
3. Bowel Urgency and Tenesmus
Many people feel a sudden, urgent need to pass stool. This urgency can be hard to control and disrupt daily life.
Tenesmus is the constant feeling of needing to empty the bowel, even when it is empty. It results from rectal inflammation.
Signs include:
- Sudden, uncontrollable urge to go
- Feeling of incomplete emptying
- Straining with little result
- Waking at night to pass stool
- Frequent trips to the toilet
Don't let bowel symptoms control your life—consult the specialists at Lux Hospitals.
4. Fatigue and Weight Loss
Ongoing inflammation and blood loss can leave you tired and weak. Poor nutrient absorption often leads to unintended weight loss.
Anemia from bleeding may worsen fatigue. Reduced appetite is common during flares.
Watch for:
- Persistent tiredness or weakness
- Unexplained weight loss
- Loss of appetite
- Pale skin from anemia
- Low energy despite rest
Other Signs to Watch For
Ulcerative colitis can affect areas beyond the gut. These extra-intestinal signs sometimes appear during flares.
Fever and dehydration may occur in severe cases. Some people share symptoms with related conditions.
Additional signs may include:
- Low-grade fever during flares
- Joint pain and swelling
- Skin rashes or sores
- Eye irritation or redness
- Mouth ulcers

What Causes Ulcerative Colitis?
The exact cause is unknown, but it involves an abnormal immune response. The immune system mistakenly attacks the colon lining.
Genetics and environmental triggers also play a role. It is not caused by diet alone, though food can affect symptoms.
Contributing factors include:
- Overactive immune response
- Family history of IBD
- Genetic predisposition
- Environmental and gut bacteria triggers
- Age (often under 30)
Possible Complications
When left untreated, ulcerative colitis can lead to serious complications. Long-standing inflammation raises the risk of colon changes.
Severe flares may need urgent hospital care. Regular monitoring helps prevent problems like colon cancer.
Complications can include:
- Severe bleeding and anemia
- Dehydration from diarrhea
- Toxic megacolon (rare, dangerous)
- Increased risk of colon polyps
- Higher long-term colon cancer risk

How Ulcerative Colitis Is Diagnosed
Diagnosis begins with a review of symptoms and medical history. Doctors then use tests to confirm inflammation and rule out other causes.
Colonoscopy is the key tool, allowing direct viewing and biopsy. Stool and blood tests support the diagnosis.
Common tests include:
- Colonoscopy with biopsy
- Stool tests for infection and inflammation
- Blood tests for anemia
- Imaging scans if needed
- Ruling out Crohn's disease
Treatment Options at Lux Hospitals
Treatment aims to control inflammation, ease symptoms, and maintain remission. Most people start with medication.
When medicines fail or complications arise, surgery may be advised. Surgical options like intestinal resections or an ileoanal reservoir surgery can offer lasting relief.
Approaches may include:
- Anti-inflammatory medicines
- Immune-suppressing drugs
- Biologic therapies
- Dietary and lifestyle support
- Surgery for severe or resistant cases
