Low blood pressure (Low BP) – Hypotension

Hypotension or Low blood pressure or Low BP is a condition which is very common amongst the Indian populace. Very common symptoms of low BP are fainting & dizziness. However in severe cases it can also become life-threatening.

What is Low Blood Pressure (Low BP)?

Blood pressure is a measurement of the pressure in your arteries during the active and resting phases of each heartbeat. Here’s what the numbers mean:

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

Diastolic pressure: The second (bottom) number in a blood pressure reading, this refers to the amount of pressure in your arteries when your heart is at rest between beats.

As per current guidelines, normal blood pressure as equal to or lower than 120/80 mmHg — 115/75 mmHg is considered even better by experts.

Blood pressure varies from individual to individual, however one can get an accurate BP reading at any given time. It might vary in a very short span of time for instance it might vary from one heartbeat to another and is dependent on positioning of body, breathing rhythm, level of stress, physical conditions, medications, food, drinks, even the time of the day.

If a blood pressure top reading  is 90 mm Hg or less (systolic blood pressure) or the bottom reading is 60mm Hg or less (diastolic blood pressure), then it is considered as low blood pressure (Low BP) condition.
