Clinically, women’s menstrual nausea is common in the following cases: 1. It is a normal physiological condition. Because during menstruation, women’s body hormone level will have obvious changes, such as estrogen, progesterone, thyroid hormone and metanephrine, etc., the content of these hormones have certain fluctuations, because the amount of these hormone fluctuations will indirectly act on the human digestive system, resulting in women’s menstrual nausea and even vomiting, anorexia and a series of digestive reactions. 2. The reason for this is that some women may experience nausea or even vomiting and anorexia during menstruation. Because some women in the menstrual period, due to emotional reactions, such as anxiety, depression, and even tension, etc., will also act on the gastrointestinal autonomic nerve through the nerve reflex, resulting in nausea, vomiting and a series of adverse reactions.
