However, some women experience more severe premenstrual symptoms that can lead to huge hormonal imbalances in their bodies

However, if a female is suffering from any mental trauma, stress, pressure, or hormonal disbalance then this duration might increase or decrease.

As earlier mentioned, there are so many symptoms or signs that one’s period is likely to approach. The inclination in the level of the hormone starts again as soon as periods begin, because of that PMS fades off.

Many women experience not many affective effects of PMS, but for some women, it becomes a very severe syndrome which gives loads of irritation and unbearable pain sometimes that constrain them to do their regular activities. If someone is experiencing severe PMS symptoms then they should immediately consult their doctors as it could be a sign of premenstrual dysphoric disorder (PMDD).


Premenstrual syndrome is not a disease that can be cured, it is a syndrome that a majority of women possess. It is painful and problematic at the same time, but the only way to lessen its effect is to take proper care of yourself and to consume a healthy diet. For some women, PMS is a minor irritation. For others, it is downright debilitating. PMS goes away when a female has attained the phase of menopause, i.e she is no longer having her periods.

There are certain medicines as well which can surely reduce one’s pain from PMS. But, the best therapy suggested by the doctors is to keep your body and mind healthy.
