Having high blood pressure (hypertension) for a year means sustained force on your artery walls, silently damaging blood vessels and vital organs, significantly raising your risk for severe, long-term problems like heart attack, stroke, heart failure, chronic kidney disease, vision loss, and cognitive decline, as the heart works harder and arteries narrow and stiffen. The longer it's uncontrolled, the greater the damage, so early management with lifestyle changes or medication is crucial.
Without treatment, high blood pressure can lead to disability, a poor quality of life, or even a deadly heart attack or stroke. Blood pressure is measured in millimeters of mercury (mm Hg). In general, hypertension is a blood pressure reading of 130/80 mm Hg or higher.
Most people with high blood pressure have no symptoms, even if blood pressure readings reach dangerously high levels. You can have high blood pressure for years without any symptoms. A few people with high blood pressure may have: Headaches.
Twenty percent of patients with hypertension are resistant. Resistant hypertension may have no symptoms at all for months or years, but then can cause heart attack, stroke, and vision and kidney damage.
Yes, extremely high blood pressure (a hypertensive crisis, 180/120 mmHg or higher) can cause nausea and vomiting, often alongside severe headaches, confusion, vision changes, or shortness of breath, signaling a medical emergency like a stroke or hypertensive encephalopathy. While routine high blood pressure usually has no symptoms, these signs mean immediate medical attention (calling 911 or emergency services) is needed.
In hypertensive emergency, call 911 if your blood pressure is higher than 180/120 mm Hg and you are experiencing symptoms that may include:
On the other hand, the life expectancy of someone with controlled high blood pressure can often be well into retirement age. With that being said, research³ does show that although you can live a long life, it may be five to seven years shorter than those without high blood pressure.
When left untreated, hypertension can lead to coronary heart disease, heart failure, stroke, kidney failure, and other problems such as memory loss. More information about memory loss can be found on the next page.
Even mild forms of high blood pressure can damage kidneys over several years.
"Stroke level" blood pressure is a hypertensive crisis, defined as a reading of 180/120 mmHg or higher, which is a medical emergency requiring immediate help (call 911 or emergency services) as it significantly increases the risk of a stroke, heart attack, or other life-threatening conditions, especially if accompanied by symptoms like severe headache, shortness of breath, or vision changes.
Some people can go years without even knowing they have hypertension. But untreated high blood pressure is dangerous to your health. Although you may not always feel the symptoms of hypertension, some people notice headache, chest pressure or shortness of breath.
Heart conditions, such as hypertension or a history of heart attacks, may disqualify someone from roles that require heavy lifting, intense physical activity, or high-stress environments.
Too much salt in the diet. Drinking too much alcohol (more than 1 to 2 drinks per day) Older age. Family history of high blood pressure (heredity)
6 Silent Symptoms of High Blood Pressure
The high blood pressure danger zone, known as a hypertensive crisis, starts at readings above 180/120 mm Hg, requiring immediate medical attention (call 911) if accompanied by symptoms like chest pain, shortness of breath, severe headache, numbness, vision changes, or difficulty speaking, as this can signal organ damage and lead to stroke or heart attack; otherwise, see a doctor urgently. Readings in Stage 2 hypertension (140/90 mm Hg or higher) are also serious and need treatment.
There is no cure for high blood pressure. But treatment can lower blood pressure that is too high. If it is mild, high blood pressure may sometimes be brought under control by making changes to a healthier lifestyle.
If your kidneys aren't working properly, you may notice one or more of the following signs:
In other words, once blood pressure rises above normal, subtle but harmful brain changes can occur rather quickly—perhaps within a year or two. And those changes may be hard to reverse, even if blood pressure is nudged back into the normal range with treatment.
a blood test that checks how well your kidneys are filtering your blood, called GFR, which stands for glomerular filtration rate. a urine test to check for albumin. Albumin is a protein that can pass into the urine when the kidneys are damaged.
If left untreated, a blood pressure of 180/120 or higher results in an 80% chance of death within one year, with an average survival rate of ten months. Any blood pressure reading in this category is considered serious, and should be evaluated by a health care provider.
During episodes of acute anxiety or panic attacks, it's not uncommon for systolic blood pressure to increase by 20 to 30 mmHg or more. These spikes are typically temporary, but they highlight the significant impact that our emotional states can have on physical health.
Without symptoms, people with high blood pressure may go years without knowing they have the condition until perhaps they've experienced a major health event, thus why it's called the silent killer.
High blood pressure (hypertension) is a major risk factor for cardiovascular disease. Severely high blood pressure, known as a hypertensive emergency, can be life-threatening. Low blood pressure (hypotension) can cause dizziness, fainting and fall-related injuries.
For those who have hypertension, regular physical activity can bring blood pressure down to safer levels. Some examples of aerobic exercise that can help lower blood pressure include walking, jogging, cycling, swimming and dancing. Another helpful type of exercise is high-intensity interval training.
