- Urinating less than 400 milliliters over 24 hours coupled with severe headaches, nosebleeds and chest pain are symptoms of severe hypertension.
- Malignant hypertension is having a blood pressure higher than 180/120mmHg. This is often a result of skipping doses.
- When you reach 40, get your blood pressure checked every 5 years at the least.
Hypertension is often symptomless. Many people have it for years without being aware of it. NHS reports that more than 25% of adults in the UK do not know that they have high blood pressure.
Hypertension occurs when there is a very high pressure of blood in your body. The extra strain on the blood vessels causes damage to the arteries and is a risk factor for stroke, heart attack and other cardiovascular diseases.
However, if malignant hypertension occurs- a dangerously sudden spike in blood pressure, symptoms manifest. A reduced urinary output of less than 400 milliliters within 24 hours results from malignant hypertension. If this comes with other symptoms including severe headaches, vision problems, chest pain, nosebleeds, blood in the urine, nausea and vomiting, this could signify a hypertensive crisis.
If you experience this whether you are hypertensive or not, best to see a doctor because this can also be a symptom of other health problems like kidney disease or dehydration.
NHS defines normal blood pressure to be between 90/60mmHg and 120/80mmHg, while high blood pressure is 140/90mmHg or higher. Malignant hypertension is beyond 180/120mmHg.
If you’re checking your own blood pressure and get a reading that high, Healthline advises people to wait a few minutes and then check again to make sure the first reading was accurate. If your second blood pressure reading is still 180 or above, don’t wait for it to come down on its own. Immediately call 911 or your local emergency services.
High blood pressure not controlled properly often results in malignant hypertension. It develops rapidly and is dangerous because it can lead to fluid in the lungs, brain swelling or bleeding and strokes. People who skip high blood pressure medications could be at risk for developing a hypertensive crisis.
The only way to know if you have hypertension is to get your blood pressure tested. NHS advises adults over 40 to have their blood pressure checked at least every five years. “Getting this done is easy and could save your life,” they said.
