Read on to learn more about chronic hypertension and its causes, diagnosis, and potential negative affects on the body.
Chronic Hypertension Symptoms
High blood pressure is called the “silent killer” because of its notorious lack of symptoms. According to the American Heart Association, when blood pressure is extremely elevated, it can cause headaches and nosebleeds, but this is not the norm. Even without causing symptoms, chronic high blood pressure is dangerous as it increases the risk of heart disease, stroke, and kidney disease. For this reason, you should never rely on a lack of symptoms or assume your blood pressure is normal.
What Causes Chronic Hypertension?
Chronic hypertension has many causes. While we don’t have control over some causes like aging, and genetics, many other risk factors are manageable. The following is a list of contributors to high blood pressure:
Aging, which causes stiffening of blood vessels over time Genetics Smoking Excess alcohol intake Poor diet Chronic stress Sedentary lifestyle Insufficient and poor quality sleep Drugs of abuse, like cocaine and methamphetamine Certain medications, like NSAIDs, corticosteroids, certain antidepressants, and hormonal contraception Medical problems like kidney disease, obstructive sleep apnea, and obesity Air and noise pollution
Diagnosis of Hypertension
Thankfully, the diagnosis of hypertension is straightforward. Blood pressure is simply measured using a blood pressure cuff. Healthcare providers measure blood pressure to screen for hypertension at your routine health exams. Hypertension is diagnosed when there has been more than one reading above 130/80 millimeters of mercury (mm Hg).
The reasons for this and other health disparities among racial and ethnic groups appear to be multifold, with a definite contribution of social determinants of health, such as access to health care.
Blood pressure measurement can be done manually with a sphygmomanometer (blood pressure cuff), or using an automated arm cuff. Automated blood pressure cuffs can be found at most pharmacies. You may also purchase your own automated cuff for measuring your blood pressure at home. This can be especially useful when blood pressure is borderline or when medications are started or adjusted.
Lifestyle
Once you have been diagnosed with elevated blood pressure it’s a good idea to consider lifestyle habits that you can modify to help bring your blood pressure down. The following changes can lower your blood pressure:
Consuming a healthy diet, with lots of fruits and vegetables and few processed foods, such as the DASH Diet or a Mediterranean Diet. This can lower your blood pressure by up to 11 points. Increasing physical activity with regular exercise can lower your blood pressure by up to four to eight points, depending on the type of exercise. Restricting salt, by avoiding things like processed foods, which are generally loaded with salt. Increasing potassium intake, ideally through the foods you eat. Many fruits and vegetables are high in potassium. Increasing potassium intake can lower blood pressure by five points. Limiting alcohol to one drink per day for women and two for men can lower blood pressure by up to four points. Quitting smoking significantly lowers the risk of heart disease and stroke and is a major recommendation for those with and without high blood pressure; however, the blood pressure-lowering effect is debated.
Blood Pressure Medication
While healthy lifestyle habits can make a big difference in blood pressure, many people need medications in addition to the healthy habits listed above. There are many different types of blood pressure lowering medications. Some of the most commonly used drug classes include:
Diuretics, like hydrochlorothiazide and chlorthalidoneACE-Inhibitors, like benazepril and lisinoprilAngiotensin receptor blockers (ARBs) like losartan and valsartanCalcium channel blockers like amlodipine and nifedipine
While any medication may have side effects, your healthcare provider can help find a medication that you tolerate well and is effective for you.
Summary
Chronic hypertension is a serious condition that may be overlooked without proper screening. It usually does not cause any symptoms but can lurk undetected and wreak havoc on your heart and other organs over time. Many risk factors for high blood pressure exist, and several are modifiable, meaning we can make healthy changes to lower risk. Diagnosis is easily performed with a blood pressure measurement, and there are many effective medications.
A Word From Verywell
If you have been diagnosed with high blood pressure, know that while it’s a serious condition, you do have control of getting your blood pressure controlled. Consider it a wake-up call to commit to the exercise program you have been meaning to get to or to make healthy changes to your diet. Small, consistent changes can have significant effects over time. And your healthcare team is there to work with you and get you on appropriate medication if needed.
