Causes Of Hypertension In Children
1. Primary hypertension
Primary hypertension means that the hypertension does not seem to be caused by some other underlyng medical condition. Many doctors think that the incidence of childhood or adolescent hypertension has been rising along with the obesity epidemic. The majority of teens and children over age 6 with hypertension have a family history of hypertension and/or are overweight.
2. Secondary hypertension
Secondary hypertension is caused by a known underlying medical condition. Of these, about
- 80 percent of children have some kind of kidney disease or blood vessel abnormalities
- 5 percent have an endocrinological disorder
- 2 to 5 percent have heart disease
Hypertension in infants with hypertension almost always has a secondary cause. In addition, premature infants have a higher incidence of hypertension.
Among kids with hypertension, especially those who are very young, secondary hypertension is more common than primary hypertension. But among children who are older than 6 to 8 years old, the ratio of primary to secondary hypertension is approaching 50/50.
Pearls And Other Issues
Isolated systolic hypertension is common in the elderly population. SBP has a better prediction for the risk of cardiovascular disease as compared to DBP. Hence, treatment of isolated systolic hypertension is beneficial to reduce all-cause mortality and cardiovascular risk, and stroke. The optimal SBP remained unclear, but an SBP goal of less than 140 mmHg and keeping DBP at 70 mmHg or higher are considered appropriate in most patient populations.

How Can You Manage Your High Blood Pressure
Treatment of high blood pressure often starts with lifestyle changes, including decreasing salt in your diet, losing weight if necessary, stopping smoking, cutting down on alcohol use, and regular exercise.
In addition to lifestyle changes, medications are often used to lower blood pressure. There are several types of medications that treat high blood pressure with each type of medication having benefits and risks that should be carefully weighed by you and your health care provider. Most people take more than one medication in order to bring their blood pressure down to their treatment goal.
Your blood pressure medication should begin to work within days. However, because high blood pressure is a long-lasting medical condition that often has little or no symptoms, remembering to take your medications can be a challenge. Combination medicines, long-acting or once-a-day medications, may be used to decrease the burden of taking numerous medications and help ensure medications regularly. Once started, the medication should be used until your doctor tells you to stop.
Controlling your blood pressure should be part of a healthy living plan and lifelong task. The damage that high blood pressure causes your internal organs does not cause any symptoms until serious damage has been done.

Do You Have High Blood Pressure
Your doctor can easily measure blood pressure. A blood pressure reading includes two numbers, one written on top of the other.
The top number is called your systolic blood pressure. This number represents the force of blood through your blood vessels during your heartbeat.
- 119 or below is the normal systolic blood pressure.
- 120-129 is elevated.
- 130-139 and greater is Stage 1 high blood pressure.
- 140 and higher is Stage 2 high blood pressure.
- 180 or above is hypertensive crisis. Call 911 immediately.
The bottom number is called your diastolic blood pressure. This number represents the force of blood through your blood vessels in between heartbeats, while your heart is resting.
- 79 or below is normaldiastolic blood pressure.
- 79 or below, combined with 120-129 systolic is elevated.
- 80- 89 is Stage 1 high blood pressure
- 90 and greater is Stage 2 high blood pressure.
Blood pressure changes throughout the day, depending on your activities. Blood pressure changes over time, as well. Systolic blood pressure tends to rise as you get older. Diastolic blood pressure may decrease as you get older.
If either of your blood pressure readings is consistently above normal, then take action right away. Work with your doctor to develop a plan to treat high blood pressure before damage to your organs occurs.
Here Is Information About One Of The Most Dangerous And Sneakiest Health Conditions: Blood Pressure
What is blood pressure?
Blood pressure is a measure of how hard your blood pushes against your arteries as it moves through your body. High blood pressure occurs when your blood pressure, the force of your blood against the walls of your blood vessels, is consistently too high. High blood pressure is harmful because it makes the heart work harder and less efficiently.
Why blood pressure matters
High blood pressure can cause significant damage to your eyes, kidneys, brain and blood vessels. Left untreated, it can lead to kidney failure or vision loss. High blood pressure also can affect your ability to think, remember and learn. There’s even a type of dementia vascular dementia caused by high blood pressure.
High blood pressure is one of the most dangerous health conditions because of how sneaky it can be. You can have high blood pressure for years without experiencing any symptoms. Even without symptoms, damage to your heart can still occur. Fortunately, high blood pressure can be easily detected. And once you know you have high blood pressure, you can work with your health care provider to control it.
How is blood pressure measured?
Blood pressure is traditionally measured using an inflatable cuff around your arm. The cuff is inflated, and the cuff gently tightens on your arm. The air in the cuff is slowly released and a small gauge measures your blood pressure.
Your blood pressure is recorded as two numbers:

How Serious Is Your Hypertension
Doctors classify hypertension according to systolic pressure and diastolic pressure readings and the effects various levels can have on your health.
Hypertension, or high blood pressure, is a health condition that affects about one in three American adults. But not everyone who has hypertension has high blood pressure to the same degree. Doctors use four hypertension categories to help classify how likely your blood pressure level is to affect your health: prehypertension, stage 1, stage 2, and hypertensive crisis.
Normal Blood Pressure
Blood pressure is measured by taking two different measurements of the pressure within your arteries: systolic pressure and diastolic pressure. Systolic pressure, the first or top number of the blood pressure reading, is the highest level of pressure in your arteries, which occurs when your heart muscle contracts and forces a burst of blood into the aorta. Diastolic pressure, which is the bottom number, is the pressure that exists within your arteries between heart muscle contractions, which is when your heart is filling with blood.
If your blood pressure reading is less than 120/80 millimeters of mercury or mm Hg , you have normal blood pressure. This means that your systolic pressure is less than 120 mm/Hg and your diastolic reading is less than 80 mm/Hg.

How Common Is Hypertension In Children
Hypertension is becoming increasingly common in children and adolescents. A recent study that looked at 15,000 adolescents found that nearly one in five had hypertension. And theres reason to believe that hypertension is vastly underdiagnosed in children, since:
- it can be difficult to measure in infants and young children
- its sometimes challenging to identify
- its often thought of as not something that really affects kids
The rise in the number of children with primary hypertension in the United States is thought to correlate with the rise of obesity.

Stroke And Brain Problems
High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities. A stroke can also kill you.
Having high blood pressure, especially in midlife, is linked to having poorer cognitive function and dementia later in life. Learn more about the link between high blood pressure and dementia from the National Institutes of Healths Mind Your Risks®external icon campaign.
What Do Blood Pressure Readings Mean
Blood pressure is measure in millimeters of mercury and recorded as two numbers, systolic and diastolic. Systolic is the top number , which measure the pressure in the arteries when the heart beats, so when its muscles contract. Diastolic the bottom number , which measures the pressure in the arteries between heart beats, so when the muscles relax and refill with blood.
The blood pressure chart reflects the categories defined by the American Heart Association. A normal blood pressure is less than 120/80. If your blood pressure numbers are between 120/80 and 139/89, you have pre-hypertension, which means that you are likely to develop high blood pressure. If your blood pressure numbers are 140/90 or above, you have high blood pressure. For instance, if your systolic blood pressure is between 140 and 159, and your diastolic blood pressure is between 90 and 99, you have Stage 1 Hypertension. You have Stage 2 Hypertension if your systolic blood pressure is over 160 and you diastolic blood pressure is over 100. If your numbers are higher than that, you are in hypertensive crisis and need emergency care.

Risk Of Injury From Falls
If your blood pressure is low enough, the drop can cause symptoms such as fainting or dizziness.This causes a significant risk of falling since youre not conscious to stop the fall. Additionally, youre not aware of how badly youve injured yourself during a fainting spell. This can lead to serious injuries, such as head trauma from hitting your head.
How Does Pulse Pressure Work
Your blood pressure is measured using two numbers, the systolic pressure and the diastolic pressure. The systolic pressure is the top number, and its a measurement of how much pressure your arteries are under each time your heart beats. The diastolic pressure, which is the bottom number, is how much pressure your arteries are under between heartbeats.
These pressures are measured in millimeters of mercury . This is because the first sphygmomanometers used to measure blood pressure had mercury in them. Mercury isnt used anymore in these devices, which are also usually called blood pressure cuffs, but millimeters of mercury is still used.
To calculate your pulse pressure, all you have to do is subtract the bottom number from the top number.
- Example: If your blood pressure was 120/80 mmHg, that would be 120 – 80 = 40.

Does Normal Blood Pressure Change With Age
Just as our blood pressure readings change according to our posture, sleep time, and stress levels throughout the day, our blood pressure changes as we age. Despite the fluctuating or changing measurements, we should maintain a normal range. As we age, we can expect changes in our cardiovascular health, including our blood pressure and cholesterol levels. There are several factors that reflect our blood pressure levels over the years, including normal blood pressure for seniors.
What Does The Systolic Blood Pressure Number Mean
Hereâs how to understand your systolic blood pressure number:
- Normal: Below 120
- Stage 1 high blood pressure : 130-139
- Stage 2 hypertension: 140 or more
- Hypertensive crisis: 180 or more. Call 911.

Whats Considered Elevated Blood Pressure
Blood pressure numbers that are higher than 120/80 mm Hg are a warning sign. It means you need to pay attention to your blood pressure and focus on heart-healthy habits.
Although these numbers arent technically considered high blood pressure, youve moved out of the normal range. Elevated blood pressure may turn into high blood pressure, which puts you at an increased risk of heart disease and stroke.
Elevated blood pressure
When your systolic pressure is between 120 and 129mm Hgand your diastolic pressure is less than 80mm Hg, it means you have elevated blood pressure.
No medications are necessary for elevated blood pressure. But your doctor may talk with you about the importance of a healthy lifestyle, such as getting regular exercise, eating a balanced diet, and managing your weight.
You may receive a diagnosis of stage 1 hypertension if:
- your systolic blood pressure is between 130 and 139 mm Hg, or
- your diastolic blood pressure is between 80 and 89 mm Hg
However, the AHA notes that if you get only one reading this high, you may not truly have stage 1 hypertension. What determines the diagnosis of hypertension at any stage is the average of your blood pressure numbers over a period of time.
Your doctor can help you measure and track your blood pressure to confirm whether its too high.
Stage 1 hypertension
If your systolic blood pressure is 130 to 139 mm Hgor your diastolic blood pressure is 80 to 89 mm Hg, its considered stage 1 hypertension.
How Do I Choose A Blood Pressure Monitor
The first step in measuring your blood pressure at home is getting a blood pressure monitorone that is accurate, fitted, validated, and works for your lifestyle. These are some things you should consider:
Get an arm cuff Devices come in many styles these days, including ones that attach to your arm and ones that attach at your wrist. Wrist cuffs can be attractive because you dont need to roll up your sleeves to use them, but they tend to give inaccurate measurements. Go with an arm cuff instead.
Choose the right cuff size The wrong cuff size can lead to inaccurate blood pressure readings. Larger cuffs are better for larger arms, and smaller cuffs are better for smaller arms. Make sure you get a size that fits you.
Make sure the device is right for your age Devices are specific to age. Some are meant for older people, and some are meant for children. As an aside, some are even meant for women who are pregnant. Make sure to get one thats right for you.
Make sure the device is validated It may be tempting to just buy the cheapest device on the internet, but you may end up with a blood pressure device that isnt approved or validated for taking an accurate measurement. Make sure yours is validated.
Newer blood pressure devices with Bluetooth integration allow you to conveniently track your blood pressure measurements through an app. This feature makes it easy to share your records with your doctor , but it usually comes at a price.

Doctors: Beware Of Low Diastolic Blood Pressure When Treating Hypertension
- Low diastolic blood pressure linked to heart damage. â
- Physicians, be aware of not dropping the bottom blood pressure number. â
- Overtreated high blood pressure could be dangerous in certain patients. â
The researchers caution that their findings cannot prove that very low diastolic blood pressure a measure of pressure in arteries between heartbeats when the heart is resting and also the lower number in a blood pressure reading directly causes heart damage, only that there appears to be a statistically significant increase in heart damage risk among those with the lowest levels of diastolic blood pressure.
A summary of the findings was published Aug. 30 in the Journal of the American College of Cardiology and coincides with the release of a similar analysis at the European Society of Cardiology Meeting by physicians from HÃ´pital Bichat in Paris, France.
Released last fall, the SPRINT trial showed protective cardiovascular benefits to patients when physicians aggressively treated high blood pressure down to 120/80 millimeters of mercury, with a primary emphasis on keeping systolic pressure the top number, representing arterial pressure when the heart is pumping at no more than 120.
Researchers followed the participants for 21 years in a series of five visits, with the last check-in in 2013. Each visit included blood pressure measurement, and several included blood testing.

Heart Attack And Heart Disease
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:
- Chest pain, also called angina.
- Heart attack, which happens when the blood supply to your heart is blocked and heart muscle begins to die without enough oxygen. The longer the blood flow is blocked, the greater the damage to the heart.
- Heart failure, a condition that means your heart cant pump enough blood and oxygen to your other organs.
