Its prevalence in the population is increasing every year and, according to the latest data, amounts to 6.8 million people worldwide. This pathological condition requires clinicians to be more vigilant about timely diagnostic and therapeutic tactics at the outpatient stage. The article demonstrates a clinical case of UC in a young patient with an atypically acute onset of the disease for his age. The described case draws attention to the role of external factors in the onset of the disease, the importance of timely diagnosis, a rational approach to treatment, and patient compliance with medical recommendations.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>ulcerative colitis, recurrent course, inflammatory bowel diseases, outpatient stageReferences</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>язвенный колит, рецидивирующее течение, воспалительные заболевания кишечника, амбулаторный этап</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
