High blood pressure can be caused by unhealthy way of life.

High blood pressure needs serious attention in order to prevent more severe health problems.

High blood pressure has three stages

Important for the origin of the disease is the lifestyle associated with overeating, obesity, sedentary life, excessive smoking, drinking lots of coffee and tea, alcohol abuse, consumption of salty foods.
Part of the reason may be attributed to heredity: the presence of a parent with high blood pressure, for example, increased by 30 percent risk of a child to turn into adulthood, high blood pressure.

Significant role in high blood pressure play kidneys. In the circulation disorder of the kidneys to form substances that have a vasoconstrictor effect, which contributes more to the greater contraction of the arteries and higher blood pressure increase.

In the development of hypertension can identify three stages:

I stage – blood pressure is erratic increased. Hypertension is temporary, functional nature, in which blood pressure may rise for a while, then returned to normal. Gradually the intervals with normal blood pressure decrease and begin the second phase of hypertension.
Stage II – blood pressure is persistently elevated, although showing some fluctuations, it tends to be higher than normal.
Stage III – high blood pressure led to less severe or more severe complications of the heart, blood vessels in the brain, kidneys and other organs. Run an intensive process of their sclerosis.

Symptoms

In the first stage of the disease patients complain most often of dizziness, tinnitus, pulsating vessels, heavy head, insomnia, and rapid fatigue.

Increased blood pressure can sometimes begin unnoticed and open accidentally. The headache is usually localized in the neck, scalp and forehead, but sometimes / often in women / nature of a migraine. Patients are often nervous, irritable.

Second Stage. In this phase of the disease the main symptoms – headaches, dizziness, tinnitus becomes permanent and permanent nature.

Third stage. Over time, if not properly applied treatment, symptoms worsen and cardiac symptoms occur: easy fatigability, tachycardia, palpitations, shortness of breath / sometimes in the form of a night attack and cardiac asthma / heart failure with constant shortness of breath, swelling, angina, more severe cases of myocardial infarction. Increased blood pressure effects on blood vessels of the brain develop severe atherosclerotic changes are driven by memory loss and changes in, in severe cases can lead to the most dangerous complication brain: cerebral hemorrhage / stroke or stroke /.

When high blood pressure runs hidden, it can happen for the first time with complications of myocardial infarction or stroke.

Essential hypertension may affect later and kidneys.
