A person has high blood pressure when the systolic pressure reading is 140 or above and the diastolic pressure is 90 or above, according to WebMD. Both numbers need not be over the limit, as one or the other indicates high blood pressure.
In adults, a normal blood pressure reading is less than 120/80 millimeters of mercury, states the American Heart Association. This measurement records systolic blood pressure, the force of blood on the arteries when the heart pumps blood, and diastolic blood pressure, the force of blood when the hea
High blood pressure in an individual is generally asymptomatic, states the American Heart Association. Some individuals experience dizziness, blood spots in the eyes, and facial flushing, or red, hot skin of the face. Symptoms of hypertensive crisis, or a blood pressure of 180/110 or higher, include
Restricting consumption of alcohol and sodium, choosing healthy foods, exercising regularly and managing weight are all ways to lower blood pressure. Making these lifestyle changes can help people reduce blood pressure without having to take prescription medications, as stated by Mayo Clinic.
When reading blood pressure numbers, the top number, known as the diastolic number, measures the pressure in millimeters of mercury inside the arteries when the heart muscle contracts, and the bottom, or diastolic, number measures the pressure within the arteries between heartbeats, according to the
In adults 20 years of age and older, normal blood pressure numbers are below 120 mm Hg (systolic) and below 80 mm Hg (diastolic), according to the American Heart Association. Blood pressure is typically expressed as a ratio with the upper number on top.
There are guidelines for an optimal blood pressure, but no "perfect" blood pressure, according to Cleveland Clinic. Generally, optimal blood pressure is less than120 mmHg systolic over less than 80 mmHg diastolic, but these numbers may vary from individual to individual depending on factors such as
Blood pressure is caused by the force of the blood as it pushes against artery walls, according to WebMD. This pressure is measured during the active and resting phases of every heartbeat.
According to Mayo Clinic, primary hypertension, or high blood pressure, has no identifiable causes and develops over time. Medical conditions such as chronic kidney disease, thyroid disease, sleep apnea, congenital blood defects and adrenal gland tumors are causes of secondary high blood pressure. O
The majority of those afflicted by high blood pressure, which is also called hypertension, experience no symptoms at all, even when blood pressure reaches dangerous levels. Those who do experience symptoms may have chest pain, fatigue, confusion, irregular heartbeat, difficulty breathing, dizzy spel
