Definition Of High Blood pressure

Today i tell definition of high blood pressure. High blood pressure is normal diseases its treatment can easily in few day.  The myth of symptoms and signs of high blood pressure
There's a common misconception that people with high blood pressure, also called HBP or hypertension, will experience symptoms such as nervousness, sweating, difficulty sleeping or facial flushing. The truth is that HBP is largely a symptomless condition. If you ignore your blood pressure because you think symptoms will alert you to the problem, you are taking a dangerous chance with your life. Everybody needs to know their blood pressure numbers, and everyone needs to prevent high blood pressure from developing.

The myth of symptomatic headaches:

The best evidence indicates that high blood pressure does not cause headaches except perhaps in the case of hypertensive crisis (systolic/top number higher than 180 OR diastolic/bottom number higher than 110).
In the early 1900s, it was assumed that headaches were more common among people with high blood pressure. However, research into the subject doesn't support this view. According to one study, people with high blood pressure seem to have significantly fewer headaches than the general population.

In a study published in the journal Neurology, people with higher systolic blood pressure (the top number in blood pressure readings) were up to 40 percent less likely to have headaches compared to those with healthier blood pressure readings. The researchers also looked at another measurement called the pulse pressure, which is the change in blood pressure when the heart contracts. Pulse pressure is calculated by subtracting the bottom number (diastolic reading) from the top number (systolic reading). Those with higher pulse pressure had up to 50 percent fewer headaches. The researchers think that the higher the pulse pressure, the stiffer the blood vessels. The stiffer the blood vessel, the less likely the nerve endings are working properly. If the nerve endings aren't functioning correctly, the less likely a person will feel pain.

Therefore, headaches or the lack of headaches are not reliable indicators of your blood pressure. Instead, work with your doctor and know your numbers.

The myth of symptomatic nosebleeds

Except with hypertensive crisis, nosebleeds are not a reliable indicator for HBP. In one study, 17 percent of people treated for high blood pressure emergencies at the hospital had nosebleeds. However, 83 percent reported no such symptom. Although it's also been noted that some people in the early stages of high blood pressure may have more nosebleeds than usual, there are other possible explanations. If your nosebleeds are frequent (more than once a week) or if they are heavy or hard to stop, you should talk to your healthcare professional.

Keep in mind that nosebleeds can be caused by a variety of factors, with the most common one being dry air. The lining of the nose contains many tiny blood vessels that can bleed easily. In a hot climate like the desert Southwest or with heated indoor air, the nasal membranes can dry out and make the nose more susceptible to bleeding. Other causes include vigorously blowing your nose; medical conditions like allergies, colds, sinusitis or a deviated septum; and side effects from some anticoagulant drugs like warfarin (Coumadin®) or aspirin.

Other inconclusively related symptoms

You should not try to evaluate your symptoms in an attempt to self-diagnose high blood pressure. Diagnosis should only be made by a healthcare professional. A variety of symptoms may be indirectly related to HBP but are not always caused by HBP, such as:

Blood spots in the eyes
Yes, blood spots in the eyes, or subconjunctival hemorrhage, are more common in people with diabetes or high blood pressure, but neither condition causes the blood spots. Floaters in the eyes are not related to high blood pressure. However, an ophthalmologist may be able to detect damage to the optic nerve caused by untreated HBP.
Facial flushing
Facial flushing occurs when blood vessels in the face dilate. The red, burning face can occur unpredictably or in response to certain triggers such as sun exposure, cold weather, spicy foods, wind, hot drinks and skin-care products. Facial flushing can also occur with emotional stress, exposure to heat or hot water, alcohol consumption and exercise, all of which can raise blood pressure temporarily. While facial flushing may occur while your blood pressure is higher than usual, HBP is not the cause of facial flushing.
Dizziness
Although it is not caused by HBP, dizziness can be a side effect of some high blood pressure medications. Nonetheless, dizziness should not be ignored, especially if you notice a sudden onset. Sudden dizziness, loss of balance or coordination and trouble walking are all warning signs of a stroke. HBP is one of the leading risk factors for stroke.
The Symptoms of Hypertensive Crisis

As mentioned above, only when blood pressure readings soar to dangerously high levels (systolic of 180 or higher OR diastolic of 110 or higher) may obvious symptoms occur. Blood pressure this high is known as hypertensive crisis, and emergency medical treatment is needed.

High Blood Pressure

High blood pressure is also know as hypertension. High blood pressure, or hypertension, rarely has noticeable symptoms. But if untreated, it increases your risk of serious problems such as heart attacks and strokes.More than one in four adults in the UK have high blood pressure, although many won't realise it.

High Blood Pressure:

The only way to find out if your blood pressure is high is to have your blood pressure checked.
Blood pressure is recorded with two numbers. The systolic pressure (higher number) is the force at which your heart pumps blood around your body.
The diastolic pressure (lower number) is the resistance to the blood flow in the blood vessels. They're both measured in millimetres of mercury (mmHg).
As a general guide:
high blood pressure is considered to be 140/90mmHg or higher
ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg
low blood pressure is considered to be 90/60mmHg or lower
A blood pressure reading between 120/80mmHg and 140/90mmHg could mean you're at risk of developing high blood pressure if you don't take steps to keep your blood pressure under control.

Risks of high blood pressure

If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes.
Persistent high blood pressure can increase your risk of a number of serious and potentially life-threatening conditions, such as:
heart disease
heart attacks
strokes
heart failure
peripheral arterial disease
aortic aneurysms
kidney disease
vascular dementia
If you have high blood pressure, reducing it even a small amount can help lower your risk of these conditions.
Check your blood pressure

The only way of knowing whether you have high blood pressure is to have a blood pressure test.
All adults over 40 are advised to have their blood pressure checked at least every five years. Getting this done is easy and could save your life.
You can get your blood pressure tested at a number of places, including:
at your GP surgery
at some pharmacies
as part of your NHS Health Check
in some workplaces
You can get your blood pressure checked at your GP practice

Causes of high blood pressure

It's not always clear what causes high blood pressure, but certain things can increase your risk.
You're at an increased risk of high blood pressure if you:
are over the age of 65
are overweight or obese
are of African or Caribbean descent
have a relative with high blood pressure
eat too much salt and don't eat enough fruit and vegetables
don't do enough exercise
drink too much alcohol or coffee (or other caffeine-based drinks)
smoke
don't get much sleep or have disturbed sleep
Making healthy lifestyle changes can help reduce your chances of getting high blood pressure and help lower your blood pressure if it's already high.
Read more about the causes of high blood pressure.
Reduce your blood pressure

The following lifestyle changes can help prevent and lower high blood pressure:
reduce the amount of salt you eat and have a generally healthy diet
cut back on alcohol if you drink too much
lose weight if you're overweight
exercise regularly
cut down on caffeine
stop smoking
try to get at least six hours of sleep a night
Some people with high blood pressure may also need to take one or more medicines to stop their blood pressure getting too high.

Medicines for high blood pressure

If you're diagnosed with high blood pressure, your doctor may recommend taking one or more medicines to keep it under control.
These usually need to be taken once a day.
Common blood pressure medications include:
ACE inhibitors – such as enalapril, lisinopril, perindopril and ramipril
angiotensin-2 receptor blockers (ARBs) – such as candesartan, irbesartan, losartan, valsartan and olmesartan
calcium channel blockers – such as amlodipine, felodipine and nifedipine or diltiazem and verapamil.
diuretics – such as indapamide and bendroflumethiazide
beta-blockers – such as atenolol and bisoprolol
alpha-blockers – such as doxazosin
renin inhibitors – such as aliskiren
other diuretics – such as amiloride and spironolactone
The medication recommended for you will depend on things like how high your blood pressure is and your age.
