Getting your blood pressure checked is nothing new. But do you understand it all?
What Exactly Is Blood Pressure?
Blood pressure’s the force of your blood pushing against the walls of your arteries. High blood pressure, or hypertension, is a common disease when that pressure of the blood flowing through the blood vessels is too high.
If your blood pressure gets too high, it can cause serious damage to your blood vessel walls, which can cause scarring, plaque buildup, narrowing of the arteries and blockage, which causes your heart to work harder. All of this can lead to heart attacks, strokes, and heart failure.
There are 2 main types of high blood pressure:
- Primary high blood pressure is the most common type and it tends to develop as you age.
- Secondary high blood pressure is caused by another medical condition or use of certain medicines and it usually goes away when this issue is treated.
Risk Factors for High Blood Pressure
- Age – Men usually develop it around age 45 and women after age 65.
- Race – High blood pressure and serious complications are more common for African Americans.
- Family history – It tends to run in families.
- Certain chronic conditions – Kidney disease, diabetes, and sleep apnea can raise your blood pressure.
- Being overweight
- Not being physically active
- Tobacco use
- Too much salt
- Too much alcohol
- Too little potassium
- Too little vitamin D
If you have some of these other risk factors, your doctor may set your blood pressure target lower.
Signs & Symptoms of High Blood Pressure
- Severe headaches
- Feeling tired
- Chest pain
- Feeling flushed in your face
- Difficulty breathing
- Pounding in your head or chest
- Irregular heartbeat
- No symptoms – Hypertension is often called the silent killer, because it often shows no early symptoms.
What Are the Numbers?
- Systolic is the pressure in your arteries when your heart contracts, the top number.
- Diastolic is when your heart rests, the bottom number.
What Are They Doing?
When a nurse takes your blood pressure, you might wonder what they’re doing. These are the steps they’re following:
- They wrap the blood pressure cuff around your arm.
- They place a stethoscope under the cuff at the crease of your elbow (where the major blood vessel of the upper arm is.)
- They inflate the cuff until it stops the flow of blood.
- They slowly loosens the cuff’s valve to let the blood start to flow again and listen for sounds in the blood vessel.
- Then, the first tapping noise they hear, they’ll note as the systolic number, the maximum pressure when the heart contracts.
- The taps fade, and they note the pressure at the last tap as your diastolic number, the minimum pressure while your heart’s at rest.
- Along with your numbers, they note which arm they took your blood pressure on and how you were positioned, like sitting with your feet flat.

It’s also normal for your blood pressure to change when you sleep, wake up, are active, and are excited or nervous.
