High blood pressure (HBP), also known as hypertension, has been coined the “silent” killer because there aren’t any significant symptoms.

And that often leads to serious health concerns for millions of people.

However, there are some signs to watch for that may indicate you have high blood pressure. Please note that the below symptoms can also be due to other health issues. To determine your blood pressure, it’s important to have it checked regularly.

Here are 9 Signs of High Blood Pressure to Look For:

1. Severe headaches
Headaches can be a sign of HBP. As blood pressure rises, pain can occur leading to severe headaches or migraines. If you aren’t experiencing headaches very often then this may not be an indicator of HBP. However, if you have frequent bad headaches, you should get your blood pressure checked.

2. Difficulty breathing
If you are having difficulty breathing most of the time or easy tasks are causing shortness of breath, this could be a sign of HBP. Specifically, you may have a condition called intracranial hypertension.

3. Nausea
When blood pressure increases, the heart pumps out less blood. This lack of oxygenated blood can cause nausea and possibly vomiting.

4. Impaired vision
High blood pressure can cause inflammation of the optic nerve which can cause blurred or temporary loss of vision.

5. Fatigue
Due to insufficient blood flow from high blood pressure, a person can experience fatigue or tiredness. So if someone is often experiencing exhaustion without an apparent reason, they should check their blood pressure.

6. Dizziness/brain fog
A lack of oxygen to the brain can indirectly cause someone to feel dizzy or like they are in a brain fog. Dizziness can also be a side effect of certain blood pressure medications.

7. Nose bleeds
HBP can harm the tiny blood vessels in your nose causing nosebleeds. If you are having frequent nosebleeds, you should see if you have hypertension.

8. Swollen feet/legs
HBP can impair kidney function leading to fluid retention and causing the legs and/or feet to swell.

9. Bluish colored skin
Cyanosis, or a bluish color to the skin, is because of a lack of oxygen in the blood. This can be the result of high blood pressure.

The best way to know if you have high blood pressure is to have regular physical exams.

For those that have been diagnosed with hypertension, there are devices you can buy that will conveniently measure it at home. Many grocery and drug stores have machines available to measure your blood pressure as well.

You can find some of the more popular at-home blood pressure monitors on Amazon too.
