Low blood pressure may appear desirable, and also for many individuals, it causes no issues. But, for a lot of people, abnormally low blood pressure (hypotension) may lead to dizziness and fainting. In acute cases, low blood pressure may be life threatening.

A blood pressure reading lower than 90 millimeters of mercury (mm Hg) for the top number (systolic) or 60 millimeter Hg to your bottom number (diastolic) is normally regarded as low blood pressure.

The source of low blood pressure may vary from dehydration to severe medical or surgical ailments. It is essential to learn what's causing your low blood pressure so that it may be treated.

Symptoms of hypotension

For some people, low blood pressure signals an underlying problem, especially when it drops suddenly or is accompanied by signs and symptoms such as:

Blurred vision
Nausea
Fatigue
Lack of concentration
Dizziness or lightheadedness
Fainting (syncope)
Shock

Extreme hypotension can result in this life-threatening condition. Signs and symptoms include:

Rapid, shallow breathing
Weak and rapid pulse
Confusion, especially in older people
Cold, clammy, pale skin
Hypotension Causes

Blood pressure is a measurement of the pressure in your arteries during the active and resting phases of each heartbeat.

Diastolic pressure. he bottom number in a blood pressure reading refers to the amount of pressure in your arteries when your heart is at rest between beats.

Systolic pressure. The top number in a blood pressure reading is the amount of pressure your heart generates when pumping blood through your arteries to the rest of your body.

During the day, blood pressure fluctuates, based on body posture, breathing rhythm, and stress level, physical illness, medicines you take, what you drink and eat, and time of the day. Blood pressure is generally cheapest at night and climbs sharply on waking.

A sudden drop in blood pressure could be harmful. An alteration of just 20 millimeter Hg -- a fall out of 110 systolic to 90 millimeter Hg systolic, for example -- may lead to dizziness and fainting once the brain fails to get a sufficient supply of blood. And large plunges, like the ones due to uncontrolled bleeding, acute allergies or allergies, may be life threatening.
