What causes nausea and vomiting during dysmenorrhea?

Possible causes of dysmenorrhea in women include inadequate warmth preservation and poor hygiene. In some cases, dysmenorrhea is accompanied by vomiting—what accounts for this phenomenon?

Why does dysmenorrhea cause vomiting?

Dysmenorrhea-associated vomiting may result from pain-induced neural reflexes that stimulate gastrointestinal motility, leading to nausea and vomiting. Symptomatic treatment is usually sufficient in such cases. Hormonal imbalances can also cause both dysmenorrhea and vomiting. Disruption of endocrine function—such as abnormal secretion of estrogen or vaginal flora—may lead to menstrual irregularities, gynecological disorders, and menstrual blood abnormalities, all contributing to painful menstruation.

Severe dysmenorrhea may trigger neurogenic spasms, potentially impairing the function of the pituitary gland and hypothalamus, ultimately resulting in nausea and vomiting. Various gynecological conditions can cause dysmenorrhea with accompanying vomiting—for example, endometriosis. In this condition, persistently elevated estrogen levels promote endometrial proliferation and swelling. Subsequent progesterone stimulation may induce bleeding, irritating local tissues and causing both pain and vomiting.

When experiencing dysmenorrhea with vomiting, prioritize keeping warm and avoid consuming raw, cold, or spicy foods. Over-the-counter ibuprofen may be used for pain relief; once pain is controlled, vomiting typically subsides. Effectively managing dysmenorrhea is crucial: patients should ensure adequate rest and sleep, avoid staying up late, and engage in regular, moderate physical activity. As overall physical health improves, dysmenorrhea often gradually resolves. Yimu Capsules (Leonurus heterophyllus-based herbal preparation) have demonstrated notable efficacy in alleviating dysmenorrhea symptoms. We hope this article has been helpful.
