Clinical Information
  • A disorder characterized by a blood pressure that is below the normal expected for an individual in a given environment.
  • Abnormally low blood pressure that can result in inadequate blood flow to the brain and other vital organs. Common symptom is dizziness but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.
  • Abnormally low blood pressure.
  • Any blood pressure that is below the normal expected for an individual in a given environment.
  • Functions related to a fall in systolic or diastolic blood pressure below normal for the age.
  • You've probably heard that high blood pressure is a problem. So what about low blood pressure?blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Both are important. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure. Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of some event or medical condition. Some people may experience symptoms of low pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.
