Disease/Condition Glossary

Blood pressure is the measurement of the heart's force to pump blood to all parts of the body. Hypotension (low blood pressure) is a condition in which the blood flows through the blood vessels at lower than normal pressures. Low blood pressure symptoms include dizziness, tiredness, lightheadedness, loss of consciousness, nausea, depression, blurry vision, or clammy (wet or sweaty) skin. Systolic pressure is the pressure when the heart pumps blood out. On the other hand, diastolic pressure is the pressure when your heart is at the resting stage between heartbeats. If your blood pressure is 90/60 mm of Hg, it means the systolic pressure is 90 mm of Hg, and diastolic pressure is 60 mm of Hg. Normal blood pressure lies in between 90/60 mm of Hg and 120/80 mm of Hg. If the blood pressure is 90/60 mmHg or lower, it is considered low blood pressure.
