What Does the Diastolic Blood Pressure Number Mean? The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen.
Over the years, research has found that both numbers are equally important in monitoring heart health. However, most studies show a greater risk of stroke and heart disease related to higher systolic pressures compared with elevated diastolic pressures.
High diastolic pressure is linked to a higher risk of disease involving the large artery called the aorta that carries blood and oxygen from the heart to distant body parts. People with an elevated diastolic reading are more prone to develop an abdominal aortic aneurysm (ballooning in the lining of the aorta).
It reflects the amount of pressure inside the arteries as the heart contracts. The bottom (second) number, diastolic pressure, is always lower since it reflects the pressure inside the arteries during the resting phase between heartbeats. As it turns out, both systolic and diastolic blood pressure are important.
Answer: If you don't have other health issues that increase your risk of cardiovascular problems, the situation you describe — isolated diastolic hypertension — isn't dangerous now. But it's not normal, either. People with elevated diastolic blood pressure often develop elevated systolic blood pressure over time.
Follow the 20 tips below to help lower your overall blood pressure, including diastolic blood pressure.
Treating and preventing high blood pressure starts with making lifestyle adjustments, such as getting regular exercise and eating a nutrient-rich diet. Drinking water and staying properly hydrated can also help maintain healthy blood pressure. In general, it's recommended to drink eight 8-ounce cups of water a day.
Normal Blood Pressure By Age
Becoming more active can lower both your top and bottom blood pressure numbers. How much lower isn't entirely clear, but studies show reductions from 4 to 12 mm Hg diastolic and 3 to 6 mm Hg systolic. Regular exercise also helps you maintain a healthy weight — another important way to control blood pressure.
Even if you're being treated for high blood pressure, your blood pressure will still rise after exercising. Walking, taking the stairs, and even lifting or moving large items can all cause your blood pressure to increase.
The factors discussed are heart rate, arterial pressure, coronary perfusion pressure, the pericardium, and the mechanical interplay between ventricles. The influence of heart rate, arterial pressure, and coronary perfusion pressure can be considered as minor provided they remain within their normal physiological range.
Diet changes can quickly lower blood pressure in many cases. A study in the journal Hypertension reported that people following the Dietary Approaches to Stop Hypertension (DASH) diet lowered their blood pressure by 1–4 millimeters of mercury (mm Hg) in 1 week.
Despite modest effect on dietary sodium restriction, no added salt diet significantly decreased systolic and diastolic BP and so it should be advised to every hypertensive patient.
Angiotensin converting enzyme inhibitors and angiotensin receptor blockers have been shown to be effective in improvement of measures of diastolic function and are recommended as first-line agents in the control of hypertension in patients with diastolic heart failure.
In healthy subjects, exercise training can enhance diastolic function and exercise capacity and prevent deterioration of diastolic function in the course of aging.
There is no cure for diastolic heart dysfunction, but the symptoms can be managed.
Studies have shown that dehydration can cause an increase in blood pressure, and a study conducted in rats recurrent dehydration can worsen hypertension. When you're dehydrated, your blood has a higher concentration of sodium, and in response, the brain sends signals to the pituitary gland to secrete vasopressin.
Water drinking also acutely raises blood pressure in older normal subjects. The pressor effect of oral water is an important yet unrecognized confounding factor in clinical studies of pressor agents and antihypertensive medications.
Over time, a lack of sleep could cause swings in hormones, leading to high blood pressure and other risk factors for heart disease.
Lemon drink contains traces of several minerals that may be beneficial in lowering blood pressure. Calcium and potassium both can lower blood pressure in those suffering from hypertension. A study suggests that lemon water can help bring the number to the normal range immediately.
