I'm on hormone replacement therapy, and my friend told me it could affect my blood pressure. Is that true?

According to the National Heart, Lung, and Blood Institute (NHLBI), blood pressure may rise in some women receiving estrogen therapy. However, a recent study found that there isn't a significant rise in blood pressure in most women undergoing HRT. To learn more about preventing, detecting, and treating hypertension, go to the NHLIBI's educational site for lowering blood pressure at www.nhlbi.nih.gov/hbp.
