Toddler's Fatigue Hid Ulcerative Colitis Battle
17 Jul
Summary
- A 3-year-old boy's fatigue and weight loss masked ulcerative colitis.
- His condition worsened over Christmas 2025, requiring hospitalization.
- After months of treatment, he entered remission in June 2026.

A young family from the U.K. endured months of worry before their 3-year-old son was diagnosed with ulcerative colitis. Initial symptoms of exhaustion and weight loss escalated into severe stomach pain and frequent bathroom needs, significantly disrupting his childhood.
The illness became particularly acute during the Christmas 2025 holiday season. The boy experienced a severe flare-up, leading to dehydration and readmission to the hospital shortly after Christmas Day.
Urgent endoscopy and colonoscopy procedures in January 2026 confirmed the diagnosis of ulcerative colitis, a condition rarely seen in such young children. This brought a mix of relief and fear for his parents.
Treatment began with prednisone, followed by sulfasalazine, azathioprine, and infliximab infusions. By June 2026, the child's fecal calprotectin levels normalized, indicating remission and allowing him to regain his energy and childhood spirit. His mother now shares their story to help others recognize warning signs.
