What is premenstrual syndrome?

Premenstrual syndrome is a kind of physiological and psychological discomfort symptoms that women experience before their menstrual period. Generally, this situation is often caused by mental or medical diseases. We will introduce it below.

Mental factors. Some women themselves are prone to mood swings, prominent mental symptoms, and often feel nervous and anxious. These negative emotions can aggravate the original symptoms.

Nowadays, many women are under great pressure in work, life, and social life, so it is easy to cause premenstrual syndrome. Therefore, they should pay attention to properly release stress in life.

Imbalance in the ratio of estrogen to progesterone. Some people believe that premenstrual syndrome is caused by relatively high estrogen levels and relatively insufficient progesterone levels in women before menstruation; it may also be caused by abnormal tissue sensitivity to progesterone.

Vitamin B6 deficiency. Vitamin B6 can promote the elimination of excess estrogen in the body and moderate emotions and behaviors. A lack of vitamin B6 may cause premenstrual syndrome.

Endorphin theory. This theory holds that since changes in endorphin levels can affect mental and neurological factors, intravenous administration of endorphins can increase prolactin concentrations. The endorphin inhibitor naloxone can change the secretion of luteinizing hormone after acting on the endorphin receptors, and β-endorphin changes with the menstrual cycle. Therefore, it is proposed that premenstrual tension syndrome is caused by changes in endorphin concentrations during the luteal phase.
