What Is Blood Pressure? A Cardiologist from Rajkot Explains
You have probably heard the term BP many times — at a doctor's clinic, at home, or in a health camp. But what does it actually mean? Dr. Nikhila Pachani, Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, explains it in simple words.
BP Is the Force of Blood in Your Arteries
Every time your heart beats, it pumps blood through a network of blood vessels called arteries. Blood pressure (BP) is the force that blood puts on the walls of these arteries as it moves through the body. It tells us how hard the heart is working to keep blood flowing to every organ — including the brain, kidneys, and the heart itself.
Understanding the Two Numbers
A BP reading always has two numbers, and both matter.
- Systolic pressure (upper number): This is the pressure in your arteries when your heart pumps (contracts). It is the higher of the two values.
- Diastolic pressure (lower number): This is the pressure when your heart relaxes between beats. It is the lower value.
For example, a reading of 120/80 mmHg means a systolic of 120 and a diastolic of 80. "mmHg" stands for millimetres of mercury — the unit used to measure blood pressure.
What Is a Normal BP Reading?
According to Dr. Pachani:
| Category | Reading |
|---|---|
| Normal | Less than 120/80 mmHg |
| High (Hypertension) | 140/90 mmHg or above |
If your BP stays above 140/90 mmHg consistently, it is called hypertension — or high blood pressure. The tricky part is that hypertension often has no obvious symptoms. Many people feel completely fine while their BP is quietly causing damage to their heart, brain, and kidneys over time. That is why doctors sometimes call it a silent condition.
Why Regular BP Checks Matter
Getting your blood pressure checked regularly is one of the simplest and most important steps you can take for your health. A quick, non-invasive check at a clinic or pharmacy can tell you whether you are in a safe range — or whether you need to act early before any harm is done.
Lifestyle choices like a balanced diet, regular physical activity, reducing salt intake, and managing stress all play a role in keeping BP under control.
