[Hypertension and hormonal contraceptives].

After several years the intake of hormonal contraceptives causes a slight increase of the arterial blood pressure in the non-hypertensive region in all women. The incidence rate of real hypertensions is 1.8 to 3 times as high as users, compared with the non-users. The cause of the increase of blood pressure is not exactly known. The estrogen-induced changes of the renin-angiotensin-aldosterone-system are most probable. Conclusions for the first prescription, the frequency of controls of blood pressure and the behaviour in the appearance of a hypertensive reaction are reported. It is particularly warned of antihypertensive therapy and permanent intake of the "pill".
