3. Symptoms

Early Symptoms vs. Advanced-Stage Symptoms

• Early Symptoms:
  • Abdominal pain and cramping
  • Frequent, small-volume bloody stools
  • Urgency and tenesmus (the sensation of incomplete evacuation)
• Advanced-Stage Symptoms:
  • Severe, persistent diarrhea
  • Significant rectal bleeding
  • Weight loss, fatigue, and malnutrition
  • Systemic symptoms such as fever in cases of severe flare-ups

Common vs. Rare Symptoms

• Common Symptoms: Include diarrhea, rectal bleeding, abdominal pain, and urgency.
• Rare Symptoms: Some patients may experience extraintestinal manifestations like joint pain, skin lesions (e.g., erythema nodosum), and eye inflammation (uveitis).

How Symptoms Progress Over Time

• Intermittent Flares: UC is characterized by periods of remission interspersed with flare-ups. Early symptoms can gradually worsen during a flare, with potential long-term complications developing if inflammation is not controlled.

4. Causes

Biological and Environmental Causes

• Biological Causes: Although the exact cause remains unclear, ulcerative colitis is believed to result from an inappropriate immune response to intestinal microbiota in genetically susceptible individuals.
• Environmental Influences: Diet, stress, and exposure to certain pathogens have been implicated in triggering disease flares.

Genetic and Hereditary Factors

• Genetic Predisposition: Family history is a known risk factor, with several susceptibility genes identified (e.g., variants in the IL-23 receptor gene).
• Hereditary Factors: Genetic studies suggest a complex inheritance pattern that influences disease onset and severity.

Known Triggers or Exposure Risks

• Triggers: Antibiotic use, diet high in fat and low in fiber, smoking (paradoxically, smoking appears protective in UC but harmful in Crohn’s disease), and stress can trigger flares.
• Exposure Risks: Changes in gut microbiota and exposure to environmental toxins may also contribute.

5. Risk Factors

Who Is Most at Risk?

• Age: UC can develop at any age but commonly presents in young adults between 15 and 35 years.
• Gender: Both genders are affected, although some studies suggest slight differences in incidence and severity.
• Lifestyle: Diet, stress, and use of certain medications may influence risk.

Environmental, Occupational, and Genetic Factors

• Environmental: Urban living and industrialized diets are associated with higher UC rates.
• Occupational: There is no specific occupational risk; however, lifestyle factors linked to occupation (e.g., stress) may play a role.
• Genetic: A positive family history increases the likelihood of developing the condition.

Impact of Pre-Existing Conditions

• Comorbidities: Patients with other autoimmune conditions may have an increased risk, and the presence of primary sclerosing cholangitis is a known risk factor for more severe disease.

6. Complications

What Complications Can Arise from Ulcerative Colitis Treatment?

• Surgical Complications: Long-term treatment may lead to surgery, which carries risks such as infection, bleeding, or pouchitis following an ileal pouch-anal anastomosis.
