Nausea after menstruation is considered a normal phenomenon. This is because the increased secretion of estrogen during menstruation can easily cause gastrointestinal discomfort, which can lead to nausea, vomiting, and in some cases, abdominal pain and bloating. Pelvic congestion during menstruation can easily cause abdominal pain, and if the pain is severe, it can also cause nausea and dry heaving, which do not need treatment, and can be recovered by themselves after menstruation is cleared. Nausea and dry heaving caused by severe dysmenorrhea need to take ibuprofen and other pain medication, and it is recommended to pay attention to abdominal warmth. If the spleen and stomach are weak, coupled with improper diet, eat indigestible food can also cause dry heaving, enteritis and other dry heaving, so dry heaving needs to be observed, if the vomiting is serious, you need to take morpholine, vitamin B6 and other drugs to regulate.
