Intramural fibroids form within the muscular walls of the uterus and are the most common type. Due to their location, they can expand and stretch the uterus, leading to symptoms such as prolonged heavy menstrual bleeding lasting more than 10 days, irregular bleeding between cycles, and discomfort in the pelvic or lower back areas.

Subserosal fibroids develop on the exterior surface of the uterus, extending into the pelvic or abdominal cavity. They may be attached to the uterus or connected via a slender stalk known as a peduncle. Women with subserosal fibroids often experience complications affecting nearby organs, including the bladder, rectum, or intestines.

Submucosal fibroids project into the inner lining of the uterus, called the endometrium. These fibroids can occur individually or in clusters and are often associated with heavy menstrual bleeding, anemia, dizziness, and fainting. Additional symptoms may include bleeding between periods, large blood clots, and pelvic or back pain. If they significantly invade the uterine cavity, they can be removed through the vagina using a hysteroscope by your OBGYN.

Pedunculated fibroids are a subtype of subserosal or submucosal fibroids that develop on a stalk, or peduncle, extending outside the uterine walls. These fibroids can cause sharp, stabbing pains if they twist on their stalk, disrupting their blood flow. Treatment may involve laparoscopic surgery (using a camera from outside the body) or hysteroscopic surgery (from within the uterus), depending on their location.
