Hypertension (high blood pressure)
High blood pressure is when the force of the blood in your arteries is higher than normal. Arteries are the blood vessels that move blood from your heart to the rest of your body.
Hypertension is a chronic condition in which the blood pressure is high most of or all the time. This can happen because of age, genetics, lifestyle, or other risk factors.
Constant high pressure in your arteries causes damage to them, and harms other blood vessels and organs especially the heart, the eyes, the kidneys and the brain. If it is not controlled, it can lead to many complications, like heart attack, stroke, or kidney disease.

Blood pressure measurements
Did you know?
- High blood pressure starts at 140/90 mm Hg or higher for either the top or bottom number
- If you are measuring your blood pressure at home, it is 135/85 or higher
About hypertension
-
Hypertension is also called high blood pressure.
-
It is a chronic condition where the force of blood against the arteries is too high (arteries are blood vessels that move blood from the heart to the rest of your body).
-
Most people with high blood pressure have no symptoms, even if their blood pressure is dangerously high. Because of this, hypertension is often called the “silent killer.”
-
The narrower or stiffer the arteries are, the higher blood pressure is.
-
Most people with high blood pressure have no symptoms, even if it is dangerously high.
-
You can have high blood pressure for many years and never feel any symptoms.
-
High blood pressure can be caused by normal narrowing of the arteries as you age, genetics (family history), lifestyle factors, and in some cases underlying medical conditions.
-
Lifestyle factors like diet, exercise, and smoking also affect your blood pressure.
-
It is more common in adults, but kids can have it too.
You are more likely to develop high blood pressure if:
-
You are older
-
You have a parent or sibling with high blood pressure (family history)
-
You have a lot of stress
-
You are obese or overweight
-
You are not physically active
-
You have a lot of salt in your diet
-
You use illegal drugs (like cocaine)
High blood pressure damages your blood vessels and organs.
If it is not controlled, it can lead to:
-
Heart attack
-
Heart failure
-
Stroke
-
Aneurysm (when a blood vessel weakens and bulges)
-
Kidney disease or failure
-
Vision loss
-
Sexual dysfunction
-
Angina (chest pain)

It's important to have your blood pressure checked periodically starting at age 18.
-
Get it checked every year if:
- You are at high risk
- You have diabetes
- You are 40 years old or over
- Your blood pressure is close to the hypertension level (130s/80s) or if one of the numbers is often high - over 140 for the top number, or over 90 for the bottom number
-
If you have hypertension (high blood pressure), your healthcare team will create a plan for you. This may include using an at-home blood pressure machine so that you can follow it more closely.
