Ulcerative Colitis
A chronic inflammatory disease of the colon characterized by periods of flares and remissions. FMT is being studied as a promising method to restore microbiome balance and reduce inflammation.
What is ulcerative colitis?
Ulcerative colitis is a chronic inflammatory bowel disease (IBD) that affects the mucosal lining of the colon.

About the condition
In ulcerative colitis, the immune system mistakenly attacks the cells of the intestinal lining, causing chronic inflammation. The disease usually begins in the rectum and can spread upward through the colon.
Symptoms
- Bloody diarrhea (the primary symptom)
- False urge to defecate (tenesmus)
- Abdominal pain, especially on the left side
- Weight loss, weakness, anemia
- Nighttime bowel movements
Causes and contributing factors
- Genetic predisposition
- Dysregulated immune response
- Gut microbiota imbalance
- Environmental factors
Standard treatment
Conventional therapy includes anti-inflammatory drugs and immunosuppressants, which are not always effective.
In 15–20% of patients, standard therapy is ineffective, and biologic medications lose their effect over time.
Why FMT for ulcerative colitis?
Microbiota imbalance plays a key role in inflammation. FMT can help restore a healthy microbiome.
Dysbiosis
Reduced microbiota diversity
Inflammation
Compromised intestinal barrier function
FMT transplantation
Introduction of healthy microbiota
Recovery
Reduced inflammation, remission
Mechanism of action
Healthy microbiota restores the balance of pro- and anti-inflammatory bacteria, strengthens the intestinal barrier, and modulates the immune response, reducing chronic inflammation.
Advantages of FMT
- Targets the cause, not just symptoms
- Potential for sustained remission
- Minimal side effects
- Alternative when standard therapy fails

Patient story
Experience of treating ulcerative colitis with FMT
"For seven years, I struggled with ulcerative colitis. Flares happened several times a year, and standard therapy was losing its effect. At Han's United, I was prescribed an intensive FMT course. After three months, symptoms decreased significantly. My quality of life changed dramatically — I can plan my life again without constantly thinking about where the nearest restroom is."
