It is one of the most underrated disorder and very often people do not realize they are suffering from it.

While high blood pressure is the much talked about and most aware condition, low blood pressure is its non-glamorous cousin. Also known as hypotension, it is a condition where the blood pressure in your arteries is abnormally low.

Naturally low blood pressure is unlikely to cause any symptoms and is normally nothing to worry about. However, if your blood pressure drops too low, it can restrict the amount of blood flowing to your brain and other vital organs, which can cause fainting or dizziness and lightheadedness.

What is low blood pressure?

The heart pumps a constant supply of blood around the body through arteries, veins and capillaries. Blood pressure is a measure of the force of the blood on the walls of the arteries as the blood flows through them. It is measured in millimeters of mercury (mmHg) and recorded as two measurements:

Systolic pressure: The pressure when your heart beats and squeezes blood into your arteries.

Diastolic pressure: The pressure when your heart rests between beats.

For example, if your systolic blood pressure is 120 mmHg and your diastolic blood pressure is 80 mmHg, your blood pressure is 120 over 80, which is commonly written as 120/80. People with a blood pressure reading of around 90/60 or less are usually regarded as having low blood pressure.

You can have blood pressure variations for many reasons, including the time of day, age, temperature, any medication you may be on, an injury, or some illness.

Causes of low blood pressure

Throughout the day, your blood pressure can vary by between 30 to 40 mmHg (both systolic and diastolic) depending on what you are doing.

  • The time of day: Your blood pressure falls overnight so will be low towards the end of the day.
  • Your age: Your blood pressure usually increases as you get older, but a drop in blood pressure from movement or eating is more common with age.
  • How stressed or relaxed you are: You have lower blood pressure when you are relaxed.
  • How much exercise you do: Initially, exercise will raise your blood pressure, but if you are healthy and exercise regularly, your blood pressure will be low when you are resting.
  • Temperature: Warm temperature may cause your blood pressure to fall.
  • If you have recently eaten: Blood will be used for digesting food in your stomach, so the blood pressure elsewhere in your body will fall.
  • Dehydration (due to sweating and/or diarrhea).
  • Medications (for high BP or other treatments).
  • Severe infection.
  • Heart attack.
  • Heart failure.
  • Pregnancy.
  • Fainting.
  • Diabetics.
  • Septic shock.
