Topic Overview

What is premenstrual syndrome (PMS)?

Most women have tender breasts, bloating, and muscle aches a few days before they start their menstrual periods. These are normal premenstrual symptoms. But when they disrupt your daily life, they are called premenstrual syndrome (PMS). PMS can affect your body, your mood, and how you act in the days leading up to your menstrual period.

Some women first get PMS in their teens or 20s. Others don't get it until their 30s. The symptoms may get worse in your late 30s and 40s, as you approach perimenopause.
