Stress can lead to persistent hypertension, although no longer in doubt by many scientists. To display a hypertension alone does not matter the size of the stress to which it is exposed, but also the way it treats.

Birth control pills and pregnancy.

Oral contraceptives increase blood pressure in a portion of women, especially those with increased body weight. These women, except that they must regularly check their blood pressure, you should try other methods of contraception after discussion with their doctor and family planning centers.  http://joel-marion.blogspot.com/2014/05/joel-marion-advice-it-is-much-better.html



Normally, blood pressure falls in the first three months of pregnancy, even in women who are hypertensive. It can grow later but for the last few months of pregnancy.

The hypertension that occurs during pregnancy is a serious problem for the mother and fetus and needs proper monitoring and drug therapy, especially in the weeks before the birth. Postpartum usually the pressure returns to normal. In severe cases the pregnant develops toxemia of pregnancy, a very dangerous situation for her life. http://www.bubblews.com/news/3437723-salad-is-one-of-the-healthiest-foods-for-weight-lossshould however be understood that hypertension is not a contraindication for women who want to have a child.

Other factors.

Other factors or conditions that may be associated with increased blood pressure is decreased physical activity, alcohol abuse, diabetes, thyroid disorders, smoking etc.

The measurement of blood pressure
The blood pressure measurement is described by two numbers. The first corresponds to the systolic pressure and the second diastolic. Both pressures measured in mm of mercury. Blood pressure is measured with a device called a sphygmomanometer (blood pressure cuff). This device consists of a cuff, an elastic "bubble" and a pressure gauge (gauge pressure).  http://joelmarionreview.tumblr.com/post/86300531243/salad-is-one-of-the-healthiest-foods-for-weight-loss
Systolic pressure
Adapting the cuff to the arm 2-3 inches above the elbow and inflating the balloon so that the manometer reading ascend and to interrupt the flow of blood in the artery of the arm. Place the stethoscope under the cuff, on the bus, at the height of the elbow deflate slowly - slowly the balloon and we hear the first sound produced in the artery as the blood begins to flow again. The pressure reading on the pressure gauge falls. Note the value in the first chime sounds. Is the sound generated by the dilatation of the artery and is perceived when the pressure in the cuff will be slightly less than the pressure in the artery. This measurement corresponds to the systolic blood pressure.

The diastolic pressure
The more you deflate the cuff, so the indicator on the pressure gauge continues to fall. We hold the evidence which stop sounding chimes in with stethoscope. This corresponds to the diastolic pressure represents the pressure of the artery located in relaxation between the contractions of the heart. In some cases, especially in the elderly, the chimes can be heard up to scratch. The doctor will explain to us and will help us to calculate correctly.
