High Blood Pressure Causes

In 90 to 95 percent of case of hypertension, the cause is unknown. In fact, you can have hypertension during years without the knowledge. This is why it is “the quiet killer” - it crawls upwards on you. When the cause is unknown, you have what is called essential or primary hypertension. The factors which can lead to hypertension in 5-10 remaining percent of cases, which are known as a secondary hypertension, include:

• Anomaly of kidney
• A structural anomaly of the aorta (large blood vessel on the basis of the heart) existing since the birth
  

These problems can usually be corrected. For example, the doctors can repair a narrowed artery which provides blood to a kidney. The majority of these problems can be eliminated by a careful history, a physical examination and some tests. The special tests are sometimes necessary, but you should not usually remain in the hospital.

How hypertension develop does?

Your heart pumps blood by the arteries of the body. The large arteries which leave your cone of heart in smaller arteries called small arteries. The small arteries then fray in smaller ships called the capillaries, which provide the oxygen and of food to all bodies of your body. Blood returns then in your heart by the veins. Certain impulses of nerve make dilate your arteries (become larger) or contract (become smaller). If these ships large are opened, blood can cross easily. If they are narrow, it is more difficult than blood the cross-piece, and the pressure inside them of the increases. Then hypertension can occur. When this occurs, your heart becomes tended and the blood vessels can become damaged. Change in the ships which provide blood to your kidneys and the brain can cause these bodies to be affected.

Your heart, brain and kidneys can handle the pressure increased for a long time. This is why you can not live during years without aucuns symptoms or bad effect. But that does not mean that it does not wound you. Hypertension is a factor of important risk for the race, the heart attack, the cardiac arrest and the failure of kidney. Complications of HBP That hypertension does make with your body? Hypertension is added to the workload of your heart and arteries. Your heart must pump harder, and the arteries carry the blood which moves under a greater pressure. If hypertension continues for a long time, your heart and arteries can not function as they would have. Other bodies of body can also be affected. There is greater risk of race, of congestive cardiac arrest, failure of kidney and heart attack. When hypertension exists with cholesterol of blood or the diabetes of obesity, of nicotinism, high, the risk of heart attack or race increases several times.

What would you say hypotension?

In some limit, more your reading of blood pressure is lower, the best. In the majority of the people, the blood pressure is not so low until it produces of the symptoms, such as the distraction or fainding. In certain states of the disease, it is possible so that the blood pressure is so low. The examples include:

• Certain nerve or disorders endocrines
  
• Rest prolonged of bed
• Reductions in the volume of blood due to the serious bleeding (hemorrhage) or dehydration

The blood pressure less than 120/80 millimeter hectogramme is generally considered ideal. Levels higher than this increase your risk for the cardiovascular disease. If you have hypotension exceptionally, make it evaluate.
