High blood pressure (or hypertension) makes the heart work harder than normal. This makes both the heart and arteries more prone to injury. High blood pressure raises the risk of having a heart attack, stroke, kidney failure, eye damage, heart failure and atherosclerosis (fatty buildups in the arteries).

Women may have an increased risk of developing high blood pressure if you are 20 pounds or more over a healthy weight (for your height and build), have a family history of high blood pressure, or have reached the age of menopause. More than 73 percent of women ages 65 to 74 have high blood pressure.

What's more, your risk of developing high blood pressure increases during pregnancy, especially in the last trimester. If not treated, high blood pressure during pregnancy can endanger you and your baby. On the other hand, if you're taking oral contraceptives, talk to your healthcare provider to evaluate the risks and benefits.
