I95: Hypotension

I95.9: Hypotension, unspecified

The heart pumps blood through the arteries to every part of the body. The pressure in the arteries must be enough for all the organs to get enough blood. On the other hand, if the blood pressure is too high, the heart, kidneys or other organs may get damaged. Under stress, our blood pressure naturally rises. During the night, our blood pressure usually falls.

The metric for blood pressure always consists of two figures. The first figure is the maximum pressure in the arteries. It occurs when the heart pumps blood out. The second value is the minimum pressure in the arteries. It occurs when the heart is filling up with blood again. A normal blood pressure can be around 120 over 80. Depending on age or pre-existing conditions, a normal blood pressure can also be slightly higher or lower.

Low blood pressure can make us feel dizzy, for example.
