PMS Causes Bad Moods?

The response to mood swings during menstruation is due to hormones and changes in their levels. Progesterone rises in the ovulation phase around day 14 of the cycle. This hormone is responsible for thickening the endometrium, the internal and functional part of the uterus.

 

In the central nervous system is the hypothalamus, whose function is to regulate emotions. It has neuronal GABA receptors that are modulators and help to bind to its neurotransmitters. Progesterone is one of these modulators, and when it is elevated, it makes the work of the GABA receptors difficult.

 

In the last phase of the menstrual cycle, progesterone levels begin to decline, so GABA receptors are released and begin to inhibit neurons related to feelings and mood swings. This is the reason why some women have mood swings during the menstrual cycle.

 

There is also a decrease in the concentration of serotonin and norepinephrine -- other neurotransmitters favoring anger, depression, and sadness. Likewise, oxytocin lowers its concentrations causing low sexual desire.

 

As you can see, several neurological alterations cause these changes. Stay calm, this is a physiological response to the rise and fall of hormones, and it will be more bearable if you give yourself peace on those days.
