Anticoncepcionais orais e pressão arterial: pesquisa epidemiológica de hipertensão arterial no Rio Grande do Sul

Effects of different hormonal contraceptives in women's blood pressure values

“…Previous studies already indicated that the presence of exogenous estrogen in the body, contained in CHCs, stimulated the RAAS and caused increased systolic and diastolic pressures due to water and sodium retention, especially in hypertensive women (4) . Four articles included in this study (12)(13)(14)(15) , two being reviews (12)(13) , indicated as result the significant increase in blood pressure by use of CHC, both in hypertensive (13) and normotensive (12,(14)(15) women.…”

“…Due to the presence of estrogen and progesterone receptors in all constituent layers of the blood vessels, the effects of female sex hormones contained in contraceptives on the cardiovascular system has been subject of scientific interest (3) . Older studies have showed that the use of contraceptive pills potentialized the increase in systolic blood pressure (SBP) in groups of women who usually presented higher pressure levels (4) . Recent studies also highlight that combined hormonal contraceptives (CHC), for containing ethinylestradiol (EE), always change the blood pressure (BP), even at low doses.…”

Pattern of Fasting Blood Sugar, Blood Pressure and Body Mass Index among Combined Oral Contraceptive (COC) Pills Users in Chencha, Southern Ethiopia: a cross-sectional study

“…Contrary to the present study, a follow-up study conducted in Minnesota, (24) reported that pill-users had a decrease in SBP and DBP after the 3rd, 6th, and12th month of follow-up. Earlier studies have shown the relationship between use of the contraceptive pill and raise of blood pressure [25]. Recent research also highlighted that, estrogen containing hormonal contraceptives always changes the blood pressure by increasing hepatic production of angiotensinogen, which in turn causes the renin-angiotensin-aldosterone system to elevate the blood pressure [26,27].…”
