Low Blood Pressure (Hypotension)

Overview of Low Blood Pressure (Hypotension)

Low Blood Pressure also known as Hypotension, is a reading of blood pressure under 90/60 mm/Hg. It frequently has no symptoms in People. When symptoms do appear, they are typically unpleasant or disruptive, including dizziness, fainting, and more. Early detection and treatment of hypotension are crucial since it can be deadly in some circumstances.

What is Low Blood Pressure (Hypotension)?

When your blood pressure is substantially lower than you would expect, you have hypotension, or low blood pressure. It can occur as a standalone disorder or as a sign of a variety of other conditions. Although it might not produce symptoms, if it develops, it could need to be treated by a doctor.

Low Blood Pressure (Hypotension) has two definitions:

  • Absolute hypotension: Your blood pressure is lower than 90/60 mmHg at rest (millimeters of mercury).
  • Orthostatic hypotension: Within three minutes of getting up from a sitting position, your blood pressure starts to fall. Your systolic (top) pressure must drop by at least 20 mmHg, and your diastolic (bottom) pressure must drop by at least 10 mmHg. Another name for it is Postural hypotension, it occurs when a person's posture shifts.

Two figures, top and bottom, both expressed in mm/Hg, are used to measure blood pressure.

  • Systolic (top number): Your systolic pressure is the pressure on your arteries each time your heart beats. A healthcare professional* squeezes your arm while inflating a cuff to measure your systolic pressure. They also listen to your pulse at a location below the cuff at the same time. When the pressure in the cuff is greater than the pressure generated by your heart's pumping, your systolic pressure is reached.
  • Diastolic (bottom number): That number is how much pressure your arteries are under between heartbeats. While deflating the cuff, the medical professional will continue to check your pulse to determine your diastolic pressure. As the cuff deflates, your diastolic pressure is the point at which they can once more hear your heartbeat.

Many modern medical devices can automatically measure your blood pressure, thanks to technological advances. The conventional stethoscope method of measuring blood pressure is no longer advised; these gadgets should be used instead.

Symptoms of Low Blood Pressure

Some patients with low blood pressure show no signs of the condition. In this, people with low blood pressure are safe.

However, showing only one or two signs could indicate a problem. the following: low blood pressure can lead to:

  • dizziness
  • fainting
  • inability to concentrate
  • blurred or distorted vision
  • nausea
  • fatigue

Some individuals may only experience low blood pressure symptoms when standing. Orthostatic hypotension is what is meant by this. Normally, this is not dangerous unless a person's blood pressure suddenly drops due to postural shifts, which could result in fainting.

Low blood pressure can result in shock in more severe circumstances. A dangerous medical emergency known as a shock is brought on by decreased blood flow throughout the body. This can result in damage to organs at the cellular level.

The symptoms of shock include the following:

  • rapid or shallow breathing
  • clammy skin
  • confusion or disorientation
  • rapid heartbeat
  • weak pulse
  • A person experiencing symptoms of shock needs urgent medical attention.
