Premenstrual syndrome (PMS) refers to a combination of physical and emotional symptoms that some women may experience in the days or weeks before menstruation. It is important to note that not all women experience PMS and that the symptoms and their severity can vary from woman to woman.
The exact causes of premenstrual syndrome are not yet fully understood. One reason could be that the women affected are hypersensitive to the normal hormonal fluctuations during the menstrual cycle.
The syndrome can include disorders such as headaches, skin problems, a slight feeling of tightness in the breasts, abdominal discomfort as well as mood swings, irritability, nervous tension, moodiness, tiredness and sleeping problems.
