Premenstrual syndrome (PMS) occur in the 1 to 2 weeks before a woman's period.
The cause of PMS is unknown. Some symptoms may be worsened by a high-salt diet, alcohol, or caffeine. The underlying mechanism is believed to involve changes in hormone levels. Reducing salt, caffeine, and stress along with increasing exercise is typically all that is recommended in those with mild symptoms.
Calcium and vitamin D supplementation may be useful in some. Anti-inflammatory drugs such as naproxen may help with physical symptoms. In those with more significant symptoms birth control pills or the diuretic spironolactone may be useful.
