in Germany have developed an implantable device that they claim can reduce
blood pressure by sending electrical signals to the brain. The study published
in the IOP's Publishing's Journal of Neural Engineering reports that the device
could offer hope to people worldwide who do not respond to existing medical
treatment for high blood
Blood Pressure Symptoms and Causes
blood pressure or hypertension
is a silent killer
disease because it rarely shows any signs and symptoms. You will be taking a
great risk if you wait for the symptoms to alert you to the problem because it
may be years before you realize that you have high blood pressure. Meanwhile,
the disease silently damages your heart, blood vessels, kidneys and other
So, health care
providers ask you to check your blood pressure regularly and 'know the
numbers'. You can then prevent from developing high blood pressure. You know
you have high blood pressure if your systolic pressure (top reading) is 140 or
more and your diastolic pressure (the lower number) is 90 or more.
Signs and Symptoms You May Show
You may have headaches
if the systolic
pressure (upper reading) is more than 180 and your diastolic pressure (lower
reading) is 110 or more. Even then scientists believe that those with high
blood pressure get fewer headaches as compared with those who don't have the
disorder. This is how they explain it - higher the pulse pressure (obtained by
subtracting lower reading from the higher reading), stiffer the blood vessels,
and consequently, less functional the nerve endings. So, you will feel the pain
Sometimes you may get nosebleeds
but it is not
indicative of high blood pressure. Nosebleeds can have other reasons as well
such as dry weather, picking the nose, deviated septum, allergies and other

a great risk factor for stroke. Get medical attention quickly.

Causes High Blood Pressure?
What causes high blood
pressure is not known. However, it occurs due to:
Narrowing of arteries by plaques •
Greater than normal volume of blood •
Faster or more forceful heart beat
or obese, sedentary
lifestyle, no exercise, smoking
, long term stress, age, family history of high BP, and
certain medical conditions can cause high blood pressure.
blood pressure cannot be cured. You can prevent it by making lifestyle changes.
In addition your doctor may prescribe blood pressure medications such as
beta-blockers, ACE inhibitors, calcium channel blockers or other drugs. Do not
attempt to treat your high BP yourself. Always consult a doctor.
don't work for some people. This is when the new implantable device can be a
"As the device will require
surgery, it is not intended to be the first port of call for treatment and will
come into play when patients, for whatever reasons, are resistant to
medication. Nevertheless, the long-term goal is to provide
'treatment-on-demand' for the patient, whereby the implantable device uses an
intelligent circuit to record the activity of the patient, for instance when
they are doing exercise, and adjust the blood pressure accordingly," says Dr.
Dennis Plachta, the lead author of the study.
Wait, don't get too
excited as yet. The researchers are yet to test it on larger animals. "We will
now look to develop the implantable device further and investigate whether it
interferes with existing medication, and ultimately test it on larger animals
such as pigs and sheep," they said.
Till the device is available for
human use, opt for the following lifestyle changes to prevent or reduce your
high blood pressure:
1. Lose inches from your tummy
and shed excess weight.
3. Eat healthy.
4. Avoid high sodium foods, viz.
processed foods, fast foods, carbonated drinks, etc. Consume less salt.
5. Avoid alcohol binging.
6. Quit smoking and avoid tobacco
8. Cut back on caffeine
Monitor your blood pressure
closely and don't miss your doctor's appointment.
