Characteristics and Causes of PMS Nausea

PMS is a mental and physical disorder that occurs 3 to 10 days before menstruation and disappears when menstruation begins.

Nausea is one of the symptoms that can be seen in the physical disorder, and it may be accompanied by other symptoms such as headache, dizziness, stiff shoulders, and diarrhea .

The cause of PMS is not clearly elucidated, but it is said to be due to the effects of female hormones and fluctuations.

After ovulation and before menstruation, progesterone is secreted during the luteal phase. Progesterone is one of the female sex hormones, and it is believed that progesterone affects premenstrual nausea.

Progesterone has the effect of suppressing gastrointestinal motility, causing bloating, gas, constipation, and nausea.
