Low blood pressure is a condition in which pressure of blood flowing through arteries and veins is so low that it causes symptoms. The condition may deprive organs and tissues of much needed oxygen and nutrients. Organs and tissues may be damaged by low blood pressure.

Blood pressure is defined by two numbers, for example 120/80. The top number is the systolic pressure and corresponds to the pressure in the arteries as the heart muscle contracts. The lower number is the diastolic pressure that corresponds to the pressure in the arteries when the heart muscle is relaxed between beats.

A normal blood pressure is defined as 120/80. Ideally, systolic blood pressure in healthy adults is 90 to 120 millimeters of mercury (mm Hg). Diastolic pressure ideally falls between 60 to 80 mm Hg.
