If there are no obvious symptoms of abdominal pain after menstruation, blood pressure is usually not affected. If an increase in blood pressure is detected during menstruation, it is usually due to an abnormality in the blood pressure itself, the most common being essential hypertension. An occasional increase in blood pressure may be related to a woman’s mood or activity. Repeated monitoring of blood pressure is needed to see if it remains at a high level, and if it returns to normal after a review, it is a physiologic change and does not require special treatment. If there is severe pain in the lower abdomen during menstruation, even causing pallor and profuse sweating, it will affect the blood pressure and lead to an increase in blood pressure. Under the stimulation of pain will affect the diastolic spasm of blood vessels, which will reflexively stimulate the blood pressure to increase, after the pain is relieved, the blood pressure will return to normal.
