Ulcerative colitis is a chronic inflammatory bowel disease affecting the colon and rectum. It causes continuous inflammation of the innermost lining, leading to bloody diarrhoea and abdominal discomfort.
Ulcerative colitis affects approximately 5 million people worldwide. Unlike Crohn's disease, it is limited to the colon and rectum and involves only the mucosal lining.
The disease typically starts in the rectum and extends proximally in a continuous pattern. Severity ranges from mild proctitis to extensive pancolitis.
Modern treatment goals have shifted from symptom control to mucosal healing, which is associated with better long-term outcomes and reduced colorectal cancer risk.
People with Ulcerative Colitis often experience the following symptoms.
The hallmark symptom — frequent loose stools mixed with blood and mucus.
An intense, often urgent need to defecate, sometimes with incontinence.
The feeling of incomplete evacuation, leading to frequent and straining bathroom visits.
Joint pain, skin lesions, eye inflammation, and liver conditions (primary sclerosing cholangitis).
Certain factors may increase your likelihood of developing Ulcerative Colitis.
Common approaches to managing ulcerative colitis. Always consult a healthcare provider for personalized treatment.
First-line treatment for mild-moderate disease. Mesalazine is effective both orally and rectally.
Anti-TNF, anti-integrin, and JAK inhibitors for moderate-severe disease not responding to conventional therapy.
For acute flare induction. Not suitable for maintenance due to long-term side effects.
Surgical removal of the colon cures the disease and is considered for refractory cases or dysplasia.
Colonoscopy showing continuous mucosal inflammation starting from the rectum. Biopsies confirm diagnosis. Faecal calprotectin monitors inflammation. Stool cultures exclude infection.
Seek emergency care if you experience severe bloody diarrhoea (6+ times daily), high fever, rapid heartbeat, or abdominal distension — these may indicate toxic megacolon.
Steps that may help reduce the risk of developing or worsening ulcerative colitis.
Medication adherence is critical
Regular colonoscopy surveillance
Avoid NSAIDs (may trigger flares)
Stress management
If left untreated or poorly managed, ulcerative colitis may lead to:
Colectomy (colon removal) is technically curative. Medical therapy aims for sustained remission without surgery.
Toxic megacolon is a life-threatening complication. With proper management, most patients have a normal lifespan.
Stress does not cause UC but can trigger flares in established disease.
