Sometimes one feels dizzy, light heade while getting up from the Bed in the morning.
You feel wobbly, there seems to be a pressure in your head.
Dizziness
If you walk, you find you are off-balance and your feet take to n a direction you do not intend..
This becomes better after some time and you are alright after you take bath in warm water.
Why?
Unless you have a History of other ailments relating to Blood Pressure, Brain, Vertigo, Ear or Spinal Cord problems, the explanation s this.
As you lie down flat , your heart need not pump as vigorously as it has to while standing,as it has no Gravity to act against, it pumpsblood at a slower pace and your blood vessels relax.
When you stand up, the Gravity pulls Blood from the heart.
Brain, as usual grabs more Blood, it tells your heart to pump harder, and your blood vessels to contract which helps increase the blood flow to your brain (there are pressure sensors that help determine this).
As this process is taking place, occasionally your will get dizzy as a result of decreased blood flow to your brain.
If the pressure sensors don’t work fast enough, and your brain doesn’t get enough blood flow, you can actually faint.
Most Medical Diagnostic tests are unnecessary and they are being done to fill the pockets of the Diagnostic Centers , a percentage of which goes to unscrupulous Doctors(not all Doctors).
Patients are best advised to seek detailed information from Doctors on Tests on the necessity and relevance of the tests before they take the tests.
They rate cars. They rate electronics. And now Consumer Reports is hoping its product-rating system will better inform consumers about why they should avoid some common heart-disease screening tests.
Blood pressure and cholesterol screenings are definitely helpful, the nonprofit group said in the report. But electrocardiograms and C-reactive protein testing are not a good idea for healthy people, it concluded.
“It’s worrisome that healthy people are getting tests they may not need because a prevention test that is not reliable can lead to a cascade of unnecessary, costly, and in some cases risky follow-up tests and treatment,” Dr. John Santa, director of the Consumer Reports Health Ratings Center, said in a statement about the report.
“It’s easier to understand the benefits than the risks,” he said in an interview Wednesday.
The magazine’s ratings are based on advice from the U.S. Preventive Services Task Force, a government-sponsored group of physicians without medical industry ties. The task force reviews and rates the scientific evidence behind some proposed procedures. (Task force recommendations on mammograms and prostate tests have been controversial the past few years.) Consumer Reports updated and added to the task force advice on cardiovascular screening tests.
Consumer Reports is also providing a heart-risk calculator on its Web site. People who type in their age, gender and cardiovascular risk profiles, such as hypertension or high cholesterol, can see their 10-year risk of having a heart attack, stroke or other cardiovascular event, and the suggested screenings.
Most healthy people, the magazine said, should only test for blood pressure, cholesterol and possibly blood glucose. But it was uncertain whether benefits outweigh risks in screening healthy people for C-reactive protein or clogged peripheral arteries. And it said risks almost certainly outweigh benefits in testing healthy people for clogged carotid arteries, abdominal aortic aneurysms and heart EKGs.
In the interview, Dr. Santa described one example of the cascade effect.
“Let’s say a nonspecific finding on an EKG that suggests you could have a problem,” he said. “The next thing you know, a CT scan is going to be suggested, so you’re going to be exposed to some significant radiation. And let’s say that the CT scan doesn’t completely exclude a problem. Well, now you’re talking about an angiogram that has a 1 or 2 percent significant side effect.
“And then of course, if you had an angiogram, let’s say you had a coronary artery that’s 50 percent blocked. Well, now wait a minute, we now know that blockage itself is not significant. There’s a lot more to having a heart problem. But it’s awful hard to look at that blockage and tell a cardiologist not to do something. But in fact all the evidence for angioplasty and heart surgery is that they help people who have chest pain, and the degree to which they help people with no symptoms at all is very, very limited, and it may not help at all. This cascade can happen quickly.”
Middle-aged women who take steps to lower their blood pressure could reduce their risk of having a stroke, heart attack, or developing heart failure, a new study shows.
Researchers say they found that high systolic pressure — the blood pressure when the heart contracts — is a significant risk factor for cardiovascular disease and its complications in middle-aged and older women.
Doctors say 36% of serious cardiovascular events such as heart attacks and strokes are preventable by lowering blood pressure in women, compared to only 24% in men.
For the study, investigators examined data on 9,357 adults in 11 countries in Europe, Asia, and South America for a median of 11 years. The researchers looked for absolute and relative risks of cardiovascular disease that were associated with systolic blood pressure.
They report that three major risk factors account for 85% of the modifiable risk for heart disease in men and women — high systolic (the top number) blood pressure, high cholesterol, and smoking. And high systolic pressure is the most important risk factor, according to the researchers.
“I was surprised by the study findings that highlight the missed opportunities for prevention of heart disease in older women,” researcher Jan A. Staessen, MD, PhD, of the University of Leuven in Belgium, says in a news release.
He says the research team found that a relatively small increase of 15 points in systolic blood pressure increased the risk of cardiovascular disease by 56% in women and 32% in men.
For the study, the researchers looked at ambulatory blood pressure, which involves measuring blood pressure at set intervals for 24 hours during a person’s daily routine and when asleep, and conventional blood pressure readings taken in doctors’ offices.
The researchers say ambulatory blood pressure readings have less potential for error and provide more accurate estimates of usual blood pressure and prognosis for cardiovascular disease.
The monitor used for ambulatory readings was a small, portable device programmed to take blood pressures at specific intervals. In the study, ambulatory readings were taken at intervals of 15 to 30 minutes during the daytime, and 30 to 45 minutes at night.
Nighttime readings are a better predictor of heart disease than daytime readings because the readings taken at night are more standardized, the researchers say. And blood pressure at night is less likely to be influenced by physical activity.
Quality of Life
“It is recognized that women live longer than men, but that older women usually report lower quality of life than men,” Staessen says. “By lowering systolic pressure by 15 [points] in hypertensive women, there would be an increased benefit in quality of life by prevention of cardiovascular disease.”
The researchers say that women and their doctors ought to become more aggressive in diagnosing and treating high systolic blood pressure.

People in a mad rush to lower blood sugar must be careful.Same applies to high BP as well as Low blood pressure is much more dangerous than high BP.I have also noticed people reducing salt intake in the belief that it would prevent high blood pressure.This is highly dangerous.You must manage salt only under Doctor’s supervision.
Intense treatment to lower blood sugar in patients with diabetes could prove nearly as harmful as allowing glucose levels to remain high, a study says. http://news.bbc.co.uk/2/hi/health/8481770.stm
