Understanding premenstrual syndrome (PMS)

Published 05/22/2020, by ,

PMS is an often unpleasant moment that precedes menstruation and affects about 75% of women of childbearing age.

This period corresponds to the 4th week of the menstrual cycle and is characterised by the accumulation of mild but distressing physical and psychological symptoms.

During this time of the month, those who are affected are more likely to suffer from headaches, breast pain, bloating, and acne, for example. Some also notice an effect on their mood and tend to feel more irritable.

Premenstrual syndrome is a known but unpredictable phenomenon that depends on each person and can be felt more or less intensely from one month to the next.


PMS seems to be closely related to hormonal fluctuations. The estrogen/progesterone ratio at this time of the cycle would act as a signal at the target tissues, causing any of these various symptoms.
