Subserosal fibroids are non-cancerous growths that develop on the outer surface of the uterus. These fibroids grow outward into the pelvic area and may cause symptoms like pelvic pain, bloating, frequent urination, and pressure on nearby organs. Unlike other fibroid types, they usually do not cause heavy menstrual bleeding but can lead to discomfort as they increase in size. Treatment options vary based on symptoms and may include minimally invasive procedures or other medical approaches.
