The Effect of Progesterone on Blood Vessels

Lowering Blood Pressure

Progesterone is a hormone found mainly in females. It can lower blood pressure because it relaxes the constriction of blood vessels. The more open blood vessels are due to progesterone counteracting angiotensin II, which is the natural substance in the body that constricts blood vessels. This direct effect on blood vessels explains the reduction in blood pressure that is usually associated with pregnancy. During pregnancy the body produces more progesterone, so the blood vessels are more open, allowing blood to flow smoothly with no buildup of pressure.

Menopause and Blood Pressure

After women go through menopause, progesterone levels are drastically reduced in the body. This explains why high blood pressure is more common in postmenopausal women. An increase in blood pressure also relates to heart health in women of a certain age since higher blood pressure is linked to heart conditions and strokes. Keeping progesterone levels up might lower the risk of these illnesses. There are several prescription drugs on the market used as angiotensin II blockers. These can keep natural progesterone levels up as well.

Blood Pressure in Both Genders

Progesterone is also found in men as well as women. It is secreted by a gland as well as and in the ovaries, which is the reason women normally have more of it in the body versus men. Not only does progesterone open blood vessels, it also blocks calcium from muscle cells in both sexes. This also aids in reducing blood pressure.
