Normal blood pressure for women is the same as for everyone else. However, women experience physiological changes that may cause the blood pressure to increase or decrease.
According to highbloodpressureinfo.org, the normal range for blood pressure for everyone is 120/80 mmHg or lower. For women, this may vary depending on menstruation and pregnancy.
Blood pressure in women may increase or decrease during pregnancy. Post-menopausal women may have a blood pressure increase of up to 5 mmHg due to the reduced levels of the hormones estrogen and progesterone. Highbloodpressureinfo.org indicates studies have been inconclusive about whether or not blood pressure increases during the menstrual cycle.
Lifestyle such as diet, stress, consumption of drugs and exercise can affect blood pressure. Additionally, family history or genetics, is another factor that determines blood pressure.
