Symptoms of High Blood Pressure (HBP-Hypertension) | Causes and Rsk Factors & Complications
Some
people suffer from high blood pressure
(hypertension - High blood pressure) for years without feeling any offer. High blood pressure and uncensored increases the risk of
serious health problems, attack and stroke.
It
determines blood pressure according to the amount of blood pumped by the heart and by the resistance level of blood flow to the arteries.
Whenever the heart to pump more blood, and whenever the
arteries narrower, the blood pressure is more elevated.
Develops
high blood pressure often over many years, and in the end it appears when
almost all people.
Fortunately, the discovery of the disease is very easy.
After the discovery of high pressure, it is possible to
control it with the help of doctors.
Symptoms of high blood pressure
Symptoms of high blood pressure in most
people who suffer from it do not show, as well as the command in the cases
where the blood pressure values recorded so high that formed a threat.
When a section of the
show patients, in the early stages of the disease, mild headaches, dizziness,
or bleeding from the nose is more than a habit. But these signs and symptoms
usually appear when the disease reaches a more advanced stage, to some extent
constituted a threat to life.
The causes and risk factors for high blood pressure
There are two types
of hypertension:
- Hyper initial blood pressure
(Main): 90% - 95% of cases in adults, it is not possible to define its
cause. It tends this type of disease, to gradually evolve, over many
years.
- Hyper secondary blood: When the 5%
- 10% remaining, generated this kind as a result of another disease
pressure. Where usually it appears suddenly and cause higher blood
pressure than that which is caused by "excessive initial blood
pressure."
Several diseases and
drugs is one of the most important of reasons
hypertension secondary, including:
- Kidney disease
- Tumors of the adrenal gland
- Certain congenital heart defects
- Certain medications such as pills
to prevent pregnancy
, drugs against colds
, medications to relieve congestion
- Pain relievers without the need of
a prescription and a number of drugs that need a prescription
- Kalecoqaian drugs and amphetamine (stimulant nervous - Amphetamine).
Several factors
increase the risk of hypertension, some of which can not be controlled.
Risk factors include:
- Age: increasing the risk of
infection with age. At the beginning of middle age, the disease is more
common among men. The women
Vimln to the incidence of the disease in the post - ( the age of
"despair" - Menopause)
- Family history: hypertension tends to move genetically.
Other additional risk factors can be controlled:
- Overweight or obesity: Whenever a
person is the highest weight, was in need of more blood in order to be
able to deliver oxygen and nutrients to different tissues of the body. The
higher the flow of the blood vessels larger amount of blood, the pressure
on the artery walls is greater.
- Lack of physical activity: the
pace of work of the heart in people who do not engage in physical activity
is higher than among those who practice it. The faster the work of the
heart, the heart needs to work harder at each contraction, which increases
the pressure on the arteries. In addition, the lack of physical activity
increases the risk of obesity.
- Smoking: Smoking tobacco leads to
raise the blood pressure of an immediate and temporary. In addition, the
chemicals found in tobacco may damage the walls of arteries. As a result,
the arteries may become narrower, leading to high blood pressure.
- Feed many salt (sodium): The
existence of a very large amount of table salt (sodium) in the diet may
lead to fluid retention in the body, which causes high blood pressure.
- Low potassium feed: Potassium
helps to balance sodium levels in cells. When it is not consumption or
storage, a sufficient amount of potassium, it could lead to the
accumulation of a very large amount of sodium in the blood.
- Low vitamin feed "d": It
is not clear whether the nutrition that lack of vitamin "d" can
cause hypertension, or not. Researchers believe that vitamin "d"
can affect the enzyme produced by the kidneys and affect blood pressure.
There is a need for additional research in this area in order to be
possible to determine how vitamin "d" on blood pressure.
- Alcohol: Drinking alcohol may
cause the secretion of hormones lead to high blood pressure and increased
heart rate.
- Tension: high levels of stress
lead to a temporary rise, but dramatically. Attempts to relax by eating
too much, smoking tobacco or drinking alcohol, may lead to the complexity
of blood pressure problems.
- Chronic diseases: some chronic diseases (including cholesterol high, diabetes , insomnia , kidney disease) may lead to increased risk of hypertension.
Sometimes pregnancy
is a factor in high blood pressure.
Hyper diffuse blood,
basically, pressure among adults, but children also may be susceptible to infection, in some cases.
It develops
hypertension in some children as a result of kidney problems or heart failure.
But a growing number of children are exposed to infection hypertension as a
result of bad lifestyle habits, such as improper and unhealthy nutrition and
lack of physical activity
Complications
of high blood pressure
Excessive blood
pressure on the artery walls, it may cause damage to the blood vessels and
other members of the body. Whenever the blood pressure is high and more
whenever remained high without treatment for a long time more, the damage is
greater.
Not to treat high
blood pressure may lead to:
- Damage to blood vessels
- Aneurysm (dilation localised to
the walls of blood vessels)
- Cardiac arrest
- Blockage or rupture of blood
vessels in the brain
- Weakness and narrowing of blood
vessels in the kidneys
- Intensify, laceration or narrowing
of blood vessels in the eyes
- Problems with memory or
understanding
