If your blood pressure remains high for a long period of time, you run the risk of damaging your blood vessels. Your stroke risk rises significantly, too. And because your heart is working harder to push blood through your system, that very valuable muscle can become overworked and grow thicker. An enlarged heart causes further complications, including heart failure. Medications and special implantable pumps can help boost heart function. But if you can manage your blood pressure before it gets too high and puts your heart at risk, you may be able to avoid a lot of complications down the road.
Sodium is a key part of how the body controls blood pressure levels. The kidneys help balance fluid and sodium levels in the body. They use sodium and potassium to remove excess fluid from the blood. The body gets rid of this excess fluid as urine. When sodium levels in the blood are high, blood vessels retain more fluid. This increases blood pressure against the blood vessel walls.
Your blood pressure is said to be “high” when either your systolic blood pressure is 140 or above, or your diastolic blood pressure is 90 or above, or both. So if your blood pressure is found to be 142/88 (systolic = 142, diastolic = 88), you are diagnosed as having high blood pressure, according to current definitions. The same would be true if your blood pressure was found to be 135/92, or 152/95. In each case, either the systolic is high, or the diastolic is high, or both. Any of these findings result in a diagnosis of high blood pressure.
The cuff is placed around the upper arm and inflated with an air pump to a pressure that blocks the flow of blood in the main artery that travels through the arm. The arm is held at the side of the body at the level of the heart, and the pressure of the cuff is gradually released. As the pressure decreases, a health practitioner listens with a stethoscope over the artery at the front of the elbow or an electronic machine senses the pulsation. The pressure at which the practitioner (or machine) first hears a pulsation from the artery is the systolic pressure (the top number). As the cuff pressure decreases further, the pressure at which the pulsation finally stops is the diastolic pressure (the bottom number).

Blood pressure fluctuates throughout the day, so measuring it in the morning might yield a different number than, say, the afternoon. Conditions like stress and lack of sleep can also fluctuate blood pressure. Visiting your doctor might feel nerve-wracking, which can elevate your blood pressure and create a condition called white coat hypertension.
If you’re feeling overwhelmed about how to make changes to your diet or if you’re trying to lose weight, you may want to consider working with a registered dietitian-nutritionist (RDN). Some people work with an RDN if they have a health condition like type 2 diabetes. In fact, high blood pressure is a risk factor for type 2 diabetes. This is partly because they share similar modifiable risk factors, like being overweight or obese, following an unhealthy diet, and having a lack of physical activity.
What is a normal blood pressure? Blood pressure is essential to life because it forces the blood around the body, delivering all the nutrients it needs. Here, we explain how to take your blood pressure, what the readings mean, and what counts as low, high, and normal. The article also offers some tips on how to maintain healthy blood pressure.

The JAMA study was an extensive chart review of over 38,000 patients at low risk for heart disease who had stage two hypertension (blood pressure between 149/90 and 159/99) and were treated with blood pressure medications. Over an average follow-up time of almost six years, they found no reduction in the risk of cardiovascular disease events or risk of death with medication use. They did, however, find an increased risk for low blood pressure, fainting, and acute kidney injury among those treated with medications.

When a direct cause for high blood pressure can be identified, the condition is described as secondary hypertension. Among the known causes of secondary hypertension, kidney disease ranks highest. Hypertension can also be triggered by tumors or other abnormalities that cause the adrenal glands (small glands that sit atop the kidneys) to secrete excess amounts of the hormones that elevate blood pressure. Birth control pills -- specifically those containing estrogen -- and pregnancy can boost blood pressure, as can medications that constrict blood vessels.
3. Implement strategies to lower inflammation. Several cross-sectional and longitudinal studies connect high blood pressure with chronic inflammation, a driving force for nearly every disease on the planet. Lowering inflammation starts with what you put on your fork. Focus on anti-inflammatory foods like wild-caught seafood (rich in omega-3 fatty acids), freshly ground flax and chia seeds, spices like turmeric, and plenty of colorful plant foods. Good sleep, stress management, exercise, and the right nutrients can also help lower inflammation.
Most people with high blood pressure are "salt sensitive," meaning that anything more than the minimal bodily need for salt is too much for them and increases their blood pressure. Other factors that can raise the risk of having essential hypertension include obesity; diabetes; stress; insufficient intake of potassium, calcium, and magnesium; lack of physical activity; and chronic alcohol consumption.
Hypertension is the most important preventable risk factor for premature death worldwide. It increases the risk of ischemic heart disease, strokes, peripheral vascular disease, and other cardiovascular diseases, including heart failure, aortic aneurysms, diffuse atherosclerosis, chronic kidney disease, atrial fibrillation, and pulmonary embolism. Hypertension is also a risk factor for cognitive impairment and dementia. Other complications include hypertensive retinopathy and hypertensive nephropathy.
Some of these drugs may decrease your body's supply of the mineral potassium. Symptoms such as weakness, leg cramps or being tired may result. Eating foods containing potassium may help prevent significant potassium loss. If your doctor recommends it, you could prevent potassium loss by taking a liquid or tablet that has potassium along with the diuretic. Diuretics such as amiloride (Midamar)*, spironolactone (Aldactone)* or triamterene (Dyrenium)* are called "potassium sparing" agents. They don't cause the body to lose potassium. They might be prescribed alone, but are usually used with another diuretic. Some of these combinations are Aldactazide*, Dyazide*, Maxzide* or Moduretic*.
Blood pressure is expressed by two measurements, the systolic and diastolic pressures, which are the maximum and minimum pressures, respectively. For most adults, normal blood pressure at rest is within the range of 100–130 millimeters mercury (mmHg) systolic and 60–80 mmHg diastolic. For most adults, high blood pressure is present if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg. Different numbers apply to children. Ambulatory blood pressure monitoring over a 24-hour period appears more accurate than office-based blood pressure measurement.
Cut down on salt. As you get older, the body and blood pressure become more sensitive to salt (sodium), so you may need to watch how much salt is in your diet. Most of the salt comes from processed foods (for example, soup and baked goods). A low-salt diet, such as the DASH diet, might help lower your blood pressure. Talk with your doctor about eating less salt.
Recurrent headaches: Headaches are fairly common among people with or without hypertension. Some people with hypertension notice changes or worsening of headaches when medications are skipped or when the blood pressure becomes higher than usual. Headaches associated with hypertension can be mild, moderate, or severe and can be of a throbbing nature.
Various expert groups have produced guidelines regarding how low the blood pressure target should be when a person is treated for hypertension. These groups recommend a target below the range 140–160 / 90–100 mmHg for the general population. Cochrane reviews recommend similar targets for subgroups such as people with diabetes and people with prior cardiovascular disease.
According to guidelines from the American Heart Association (AHA) and the American College of Cardiology (ACC), a reading below 120/80 mm Hg is classified as normal blood pressure. Those with a blood pressure reading anywhere from 120/80 up to 129/80 are classified within a category called elevated blood pressure. Hypertension is defined as a reading of 130/80 or higher.
Be proactive and follow all medical advice received about how to manage hypertension. It is crucial to continue on any prescriptions given to treat hypertension. It is very dangerous to stop taking a medication for hypertension just because the symptoms seem to have lessened. Have frequent medical checkups and stay in touch with the doctor if any new symptoms arise.

Electrocardiogram (ECG): This tests the heart's electrical activity. This test is more commonly used for patients at high risk of heart problems, such as hypertension and elevated cholesterol levels. The initial ECG is called a baseline. Subsequent ECGs may be compared with the baseline to reveal changes which may point to coronary artery disease or thickening of the heart wall.
Beta blockers decrease the effect of adrenaline on the cardiovascular system, slow the heart rate, and reduce stress on the heart and the arteries. Side effects include worsening shortness of breath if you have chronic obstructive pulmonary disease or asthma; sexual dysfunction; fatigue; depression; and worsening of symptoms if you have peripheral artery disease. Beta-blocker examples include:
