What is premenstrual syndrome (PMS)?

Premenstrual syndrome (PMS) is a group of symptoms related to the menstrual cycle. PMS symptoms occur in the week or two weeks before your period (menstruation or monthly bleeding). The symptoms usually go away after your period starts. PMS may interfere with your normal activities at home, school, or work. Menopause, when monthly periods stop, brings an end to PMS.
The causes of PMS are not yet clear. Some women may be more sensitive than others to changing hormone levels during the menstrual cycle. Stress does not seem to cause PMS, but may make it worse. PMS can affect menstruating women of any age.
PMS often includes both physical and emotional symptoms. Diagnosis of PMS is usually based on your symptoms, when they occur, and how much they affect your life.

What are the symptoms of PMS?

PMS often includes both physical and emotional symptoms. Common symptoms are:
breast swelling and tenderness
fatigue and trouble sleeping
upset stomach, bloating, constipation or diarrhea
headache
appetite changes or food cravings
joint or muscle pain
tension, irritability, mood swings, or crying spells
anxiety or depression
trouble concentrating or remembering.
Symptoms vary from one woman to another. If you think you have PMS, try keeping track of your symptoms for several menstrual cycles. You can use a calendar to note which symptoms you are having on which days of your cycle, and how bad the symptoms are. If you seek medical care for your PMS, having this kind of record is helpful.

How common is PMS?

Estimates of the percentage of women affected by PMS vary widely. According to the American College of Obstetricians and Gynecologists, up to 40 percent of menstruating women report some symptoms of PMS. Most of these women have symptoms that are fairly mild and do not need treatment. Some women (perhaps five to ten percent of menstruating women) have a more severe form of PMS.
