What are Uterine Polyps?

Like fibroids, polyps are growths that develop around the uterine wall, but that’s where the similarities end. That’s because polyps are tied to your periods.

Over time, roundish growths (polyps) may develop as the uterine lining returns.  There are two types of polyps: pedunculated (attached to the uterine wall by a stalk) or sessile (attached by a large base). Most polyps range in size from a few millimeters to a few centimeters.

Pedunculated polyps are the most. And they may stick out of your uterus into the vagina. However, the polyps won’t be painful unless they protrude. Of course, polyps cause other symptoms, including irregular periods, spotting between menstrual periods, infertility and bleeding after menopause.
