What is LARS?

LARS, or Low Anterior Resection Syndrome, refers to bowel function changes following Low Anterior Resection Surgery for rectal cancer. Symptoms may include increased bowel frequency, urgency, clustering, and incontinence. Management often involves dietary changes, use of stool bulking medications, pelvic floor exercises, transanal irrigation, and support from healthcare professionals to improve quality of life for affected individuals.
