Premenstrual syndrome, more commonly known as PMS, is a disorder that occurs a week or two before menstruation begins and is characterized by a wide range of symptoms, including bloating, breast tenderness, emotional changes, irritability, cramps, and fatigue. Some women with PMS experience just a few of these symptoms and find them quite mild and tolerable while others have several symptoms, each so intense as to be incapacitating. Most women's symptoms exist somewhere between the two extremes, producing a moderate level of discomfort and at least some disruption of daily activities.
Hormone imbalance is a common problem with PMS. While excessive estrogen and progesterone deficiency (or an imbalanced ratio between the two) are believed to be the key imbalance, there can also be other issues such as low thyroid. The liver also plays a key role in the management of PMS, as it is responsible for metabolizing hormones. Improving liver function with natural therapies often helps to lessen the symptoms of PMS.
