What is low blood pressure?

Many people worry about low blood pressure (hypotension) but probably don’t need to. Some people have a blood pressure level that is lower than normal. In general, this may be good news – because the lower your blood pressure is, the lower your risk of stroke or heart disease. However, in a few cases, having low blood pressure can cause problems, so you might need to speak to your doctor or nurse.

Types of low blood pressure: causes, signs & symptoms

There are several types of low blood pressure. Each is linked to a different cause and leads to different signs and symptoms. The four main types of low blood pressure are:

  • Chronic asymptomatic hypotension
  • Orthostatic hypotension
  • Neurally mediated hypotension
  • Severe hypotension linked to shock

Most doctors will only consider chronically low blood pressure as dangerous if it causes noticeable signs and symptoms, such as:

  • Fainting (syncope)
  • Fatigue
  • Depression
  • Dehydration and unusual thirst
  • Dehydration can sometimes cause blood pressure to drop.
  • Lack of concentration
  • Rapid, shallow breathing
  • Blurred vision
  • Cold, clammy, pale skin
  • Nausea
  • Dizziness or lightheadedness

Is low blood pressure dangerous?

Usually, having low blood pressure is not a cause for concern. However, sometimes your blood pressure can drop to a point where you may feel faint or dizzy. If you find that your blood pressure is suddenly much lower than usual, there may be a reason for this. Speak to your doctor or nurse.
