About low blood pressure

Low blood pressure (hypotension) refers to a blood pressure that’s lower than normal or lower than would be expected in a particular person. Blood pressure is a measurement of the force that your blood puts on the walls of your arteries as it’s pumped around the body. There is no set threshold for what’s considered too low as a low blood pressure reading for one person might be perfectly okay for that individual, but doctors may consider a reading below about 100/60 mmHg cause for concern if it’s having a negative impact on the body.

If blood pressure becomes lower than normal for you, blood flow to vital organs may cause fainting, blurred vision or fatigue.

Symptoms of low blood pressure

Low blood pressure is normally a good thing but it may need medical attention if not enough blood reaches the organs and causes symptoms such as dizziness and fainting.

The symptoms associated with low blood pressure usually develop over time. These include:

Dizziness or light-headedness Shortness of breath Fainting Cold hands and feet Feeling tired Feeling weak and shaky

Often these symptoms become apparent when a person stands suddenly – “postural” (or orthostatic) hypotension. Symptoms that arise after eating a big meal indicate “postprandial” hypotension.

Low blood pressure can affect anyone in certain situations, such as standing for long periods in a hot place or following a period of intense stress or emotion. However, it’s when low blood pressure regularly causes symptoms that there may be other factors like dehydration, pregnancy, internal bleeding etc. may be  involved.
