PMS

In the luteal phase of the menstrual cycle, many women suffer from premenstrual syndrome, when the falling level of oestrogen and high levels of progesterone lead to certain physiological and psychological changes. About one week before menstruation, women may experience tender breasts, weight gain, headaches, muscle and joint pain and loss of appetite, or an increase in appetite. The most common mental symptoms of PMS are depression, anxiety, mood swings, poor sleep and nervousness.
