What causes dysmenorrhea accompanied by nausea and vomiting?

　　In fact, dysmenorrhea refers not only to abdominal pain occurring during menstruation and the days immediately before and after it, but also encompasses both primary and secondary forms. Primary dysmenorrhea is caused by unhealthy dietary and lifestyle habits, whereas secondary dysmenorrhea results from various gynecological disorders. So, why does nausea and vomiting sometimes accompany dysmenorrhea?

　　Why Does Nausea and Vomiting Occur with Dysmenorrhea?

　　Nausea and vomiting are common symptoms associated with dysmenorrhea. During menstruation, the endometrium sheds, creating fresh wounds within the uterine cavity. Bacteria may then enter these sites, leading to inflammation of the genital tract, increased menstrual blood volume, or prolonged menstrual duration—all of which can exacerbate dysmenorrhea. Dysmenorrhea is defined as spasmodic lower abdominal pain and systemic discomfort occurring before, during, or shortly after menstruation, significantly impairing daily functioning. It is classified into primary and secondary types. Primary dysmenorrhea is diagnosed when comprehensive gynecological clinical examinations reveal no obvious abnormalities in the pelvic organs.

　　Secondary dysmenorrhea arises from identifiable pathological conditions affecting the reproductive organs—such as endometriosis, pelvic inflammatory disease, or tumors. Although many women experience irritability before or during menstruation, it is advisable to maintain a positive mood throughout the menstrual period to prevent complications such as delayed menstruation, dysmenorrhea, or amenorrhea—and to avoid emotional fluctuations or overexcitement when dealing with stressful situations.

　　In daily life, maintain regular eating habits: avoid spicy and stimulating foods, refrain from binge eating, and ensure adequate sleep—avoiding late-night activities. We hope this information proves helpful to you.
