Menstrual cramps and the urge to vomit are related to the rise in the level of prostaglandins, which cause excessive contractions of the uterus and can lead to menstrual cramps. If prostaglandins enter the body’s blood circulation, they can also cause contraction and spasm of the smooth muscles of the gastrointestinal tract, resulting in nausea and vomiting. So once a patient with dysmenorrhea has painful periods and wants to vomit, he or she must pay attention to rest, keep warm, don’t get cold or chilled, and drink more warm water or ginger sugar water, which is helpful for relieving dysmenorrhea. In addition, if the symptoms of dysmenorrhea are more serious, you need to take oral pain medication, such as Fenbid or Yuanhu painkiller tablets, etc. If necessary, go to the hospital for examination to clarify the diagnosis and the next treatment plan, etc.
