Causes of Hypertension

 

A blood pressure of 140/90 or higher is high blood pressure. Both numbers are important. If one or both numbers are usually high, you have high blood pressure. If you are being treated for high blood pressure, you still have high blood pressure, even if you repeated a position in the normal range.

Causes

Approximately 90% to 95% of cases of hypertension referred to the primary or essential hypertension have no known cause. Primary hypertension may be influenced by factors such as genetic predisposition, weight or the amount of salt. Research is underway to learn more about playing the role of genes in hypertension and to explore the relationship between factors such as hypertension and obesity, low birth weight, and low levels of nitric oxide. Nitric oxide is a molecule that affects the smooth muscle cells that line blood vessels. People with low nitrogen oxide have been found have high blood pressure, particularly African-Americans with lower levels of the molecule.

Family ties to PPH

Studies show that at least 15 to 20% of patients with primary pulmonary hypertension have an inherited form of the disease. We do not know if it is a sporadic genetic defect in these families.

Two types of hypertension are recognized. By far the most common is essential hypertension, sometimes called primary hypertension. This is hypertension in which there is no identifiable cause. Ninety percent of people with hypertension, essential hypertension. Although researchers have been unable to determine the precise causes just to increase several risk factors is undoubtedly a unique opportunity for the development of essential hypertension.

Changes in the arteries that can complicate the problem. Normally, the arteries are elastic and do not extend beyond the contract and in rhythm with the heart, they adjust the volume of blood and other conditions in the body, stretching or tightening, if necessary, reduce or maintain blood pressure. Several factors – stress, for example – as well as nutrition, genetics, lifestyle and aging, have an adverse effect on the arteries. They are less resilient and therefore less able to adapt to changes in the body, and they tend to take a cholesterol, arterial plaque, a deposit of fat deposits that clog pipes in your home, you can save your sink. CAUSE



For most people, (the causes of hypertension are not known), also known as hypertension. This type of high blood pressure is called primary or essential hypertension. For some people, the cause of hypertension is the result of another medical problem or medication. If the causes of hypertension are known, the condition is called secondary hypertension.

About 30% of cases of essential hypertension are attributable to genetic factors. For example, the United States, the incidence of hypertension is higher among African Americans than for whites or Asians. Even among those who have one or both parents with hypertension, high blood pressure is twice as common in the general population. In rare cases, certain unusual genetic disorders that cause the adrenal cortex hormones in hypertension.
