Premenstrual syndrome (PMS) refers to the complex of physical and emotional symptoms that may occur from one to two weeks, or just a few days, before menstruation. These symptoms usually disappear when your menstrual bleeding starts or within a day or two of the start of your period. If your symptoms last longer than this, speak to your doctor about other possible causes of these symptoms. Do you suffer from PMS? Try this quiz.

The cause of premenstrual syndrome is not known. Theories such as hormonal imbalance or various vitamin deficiencies have been suggested, but not proven.

Treatment of PMS is targeted at the specific symptoms and may include:

• Relaxation techniques (such as yoga orrelaxation tapes).
• Dietary changes (e.g. reduction in salt, caffeine, alcohol).
• Medications to increase fluid loss (diuretics).
• Medications to reduce pain (analgesics).
• Birth control pills (oral contraceptives).
• Vitamin and mineral supplements.

Many women are occasionally or regularly affected by premenstrual symptoms. If your symptoms interfere with your normal life, either socially or at work, discuss treatment options with your family doctor.
