What causes nausea and vomiting during menstruation?

　　Nausea and vomiting during early pregnancy are normal physiological responses to pregnancy and are relatively common. Some women may experience regular menstrual periods, confirm they are not pregnant, and have not consumed spoiled food, yet still suffer from nausea and vomiting during menstruation. So, what causes nausea and vomiting during menstruation?

　What Causes Nausea and Vomiting During Menstruation?

　　Nausea and vomiting during menstruation may result from premenstrual tension syndrome, gastrointestinal dysfunction, or emotional stress. Some women begin experiencing nausea and vomiting approximately one week before menstruation; symptoms typically peak just before and during menstruation and usually subside within three to four days after the period ends. This condition is known as premenstrual tension syndrome (PMS), primarily caused by neuroendocrine imbalances occurring during the menstrual cycle. During menstruation, estrogen secretion increases in women, which can adversely affect gastrointestinal function and potentially lead to gastrointestinal dysfunction. Consequently, symptoms such as abdominal distension, pain, a sensation of greasiness, nausea, and vomiting may occur. Additionally, women’s physical resistance tends to decline during menstruation, and their emotions often become more sensitive. Excessive stress at this time may cause heightened emotional tension, resulting in gastrointestinal discomfort—including nausea and vomiting.

　　During menstruation, avoid overexertion; ensure adequate rest, refrain from staying up late, and take precautions against colds. Try to relax, maintain a positive mood, listen to music to divert attention, and thereby alleviate nausea and vomiting.

　　Avoid consuming excessively greasy foods; instead, opt for light, easily digestible meals such as plain congee. We hope this information proves helpful to you.
