Low Blood Pressure


Low blood pressure (hypotension) occurs when a person’s blood pressure is much lower than normal, i.e., the other body parts like the heart and brain do not get sufficient blood. Healthy blood pressure is chiefly between 90/60 mmHg and 120/80 mmHg.


Some signs and symptoms of low blood pressure may involve:

  • Blurry vision
  • Confusion
  • Feeling dizzy, lightheaded, or fainting 
  • Nausea or vomiting
  • Sleepiness
  • Weakness


In a healthy person, lower than normal blood pressure does not cause symptoms and often does not need treatment. Otherwise, treatment depends on the cause and the symptoms.

When one has symptoms due to a dip in blood pressure, it is recommended to sit or lie down immediately and raise the feet above heart level.

Overbearing hypotension caused by shock is considered to be a medical emergency. One may be given:

  • Blood through a needle (IV)
  • Medications to increase blood pressure and improve heart strength
  • Other drugs, such as antibiotics

Treatments for low blood pressure after standing up too swiftly involve:

  • If already under medication, one may need to change the dosage or switch to a different drug. 
  • Taking more fluids to treat dehydration.
  • Wearing compression stockings can help keep blood from collecting in the legs and keeping more blood in the upper body.

Additional treatments involve increasing salt in the diet. In severe circumstances, medications may be prescribed.

Fact Sheet

Tips: A range of 120/80 mmHg should be the benchmark in assessing blood pressure levels. It is always good to buy a portable machine that tests blood pressure which gives an accurate blood pressure reading to understand when and how pressure fluctuates. 

PGC Resolution: Providing evidence-based recommendations, information, and treatment of hypotension. Recommending the target blood pressure to be achieved for control.
