Diastolic blood pressure measures the pressure on artery walls when the heart is at rest. A sphygmomanometer measures blood pressure in mmHg. Normal blood pressure for adults is between 90-119/60-79 mmHg. High blood pressure can cause serious health problems, while low blood pressure can cause dizziness and fainting. Blood pressure should be checked regularly, especially for those taking medication.
Diastolic blood pressure measures the pressure exerted by the heart against the artery walls when the heart is at rest. Usually displayed in conjunction with systolic blood pressure, diastolic pressure marks the end of the cardiac cycle, when the heart fills with blood. Systolic blood pressure, on the other hand, marks the beginning of the cardiac cycle, when the heart contracts. The difference between systolic and diastolic blood pressure is called pulse pressure.
One of the tools used to read heart pressure is a sphygmomanometer. Written as a fraction, heart pressure is measured in millimeters of mercury (mmHg). Systolic blood pressure is represented by the highest and largest number, while diastolic blood pressure is the lowest and smallest number.
Blood pressure can change throughout the day, depending on temperature, exercise, narcotic use, and posture. It is recommended that an individual check their blood pressure several times throughout the day to get a more accurate assessment. You can check your blood pressure in a doctor’s office or at home. One disadvantage of going to the doctor is that an individual may feel nervous about the visit and thus inaccurately show higher blood pressure. This is called white coat hypertension.
For a healthy adult, 18 years of age and older, a normal systolic blood pressure of between 90 and 119 mmHg is considered. A normal diastolic blood pressure is between 60 and 79 mmHg. An individual whose systolic blood pressure is below 90 and diastolic blood pressure below 60 may suffer from hypotension. On the other hand, a systolic blood pressure above 140 and a diastolic blood pressure above 90 indicate hypertension. One of the ways an individual can lower their blood pressure is by losing weight, eating healthier, and exercising.
High blood pressure, called high blood pressure, can cause kidney disease, heart failure, blindness, heart attack and stroke. Low blood pressure, called hypotension, can cause dizziness, nausea, and fainting. Some of the causes of low blood pressure include dehydration, gland disorders, and infections.
For younger people, diastolic blood pressure is a good indicator of high blood pressure, as higher diastolic blood pressure increases the likelihood of having high blood pressure. Systolic blood pressure increases as people age and becomes a more important factor in determining hypertension. Older people with higher systolic blood pressure are more likely to suffer stroke, kidney disease and heart attack.
Adults over the age of 18 are advised to have their blood pressure checked once a year. An individual may not experience any symptoms of high blood pressure, which is why it is imperative to conduct control. Checking blood pressure for people who are taking high blood pressure medications can reveal whether their treatment is working.
