Oral contraceptives are known to have the potential to increase blood pressure in some individuals. This effect can largely be attributed to the estrogen component in many combination oral contraceptives, which can lead to sodium and fluid retention, ultimately resulting in an increase in blood volume and cardiovascular resistance.

Studies indicate that the use of oral contraceptives can raise blood pressure, particularly in women who may already have a predisposition to hypertension or are at higher risk for cardiovascular issues. The increase is often modest but can become more significant in women with risk factors such as obesity, a family history of hypertension, or existing cardiovascular disease.

While some individuals may not experience any changes in blood pressure, the general understanding is that there is a risk of elevation for the population using these contraceptives. Therefore, monitoring of blood pressure is often recommended for women who start taking oral contraceptives, especially if they have known risk factors for hypertension.
