Why do I have nausea during this menstrual period? What is the reason?

Patient's question:

No

Doctor's answer:

With premenstrual tension syndrome, it is associated with an elevated ratio of endogenous estrogen/progesterone, leading to excessive estrogen in the body or relatively excessive estrogen, causing fluid and sodium retention in the body, resulting in symptoms such as edema and headaches. Additionally, people who are usually tense, irritable, or depressed are more prone to premenstrual tension syndrome.
