A diastolic blood pressure (DBP) of somewhere between 60 and 90 mm Hg is good in older people. Causes of low DBP include bed rest, dehydration, loss of water, alcohol use, hormone deficiencies, allergic reactions, nutritional deficiencies, and prolonged standing leading to blood pooling in the legs. A decrease in your diastolic blood pressure (DBP) probably represents age-related stiffening of the arteries. Blood vessels get stiff and narrow with age. They do not recoil as they should when the blood column tries to pass through. Therefore, blood pressure shows a low reading on the diastolic scale. This means the heart has to pump blood against increased resistance. The difference between your systolic blood pressure and DBP therefore increases. Other causes of low DBP are as follows.
Which is more important, systolic or diastolic blood pressure?In practice, systolic blood pressure should be regarded as more important than diastolic blood pressure (DBP). In general, there is a high correlation between systolic blood pressure and heart health. However, both systolic blood pressure and DBP are important risk factors for heart disease.
According to a recent study, having DBP or systolic blood pressure that’s too high is a health risk but for different reasons.
Research favored high systolic readings as the most predictive of a harmful cardiovascular outcome. As a result, these readings were given more weight in cardiology guidelines and in estimating risk. SLIDESHOWLow Blood Pressure (Hypotension): Symptoms, Signs, Causes See Slideshow10 Possible signs and symptoms of low diastolic blood pressure (DBP)A diastolic blood pressure (DBP) of somewhere between 60 and 90 mm Hg is good in older people. Once your blood pressure reading plummets to below 60 mm Hg, you may faint. Many older people with low DBP get tired or dizzy and have frequent falls. Obviously, none of that is good news for people who are older and who may have brittle bones and poor healing. 10 Common signs and symptoms of low DBP may include
Studies have reported that very low DBP is associated with an increased risk of heart disease. Importantly, a study found that low DBP was associated with an increased likelihood of coronary heart disease events and mortality. Studies have explained that if individuals have DBP that is too low, there might not be enough blood flow to the heart muscle itself. This could lead to heart attacks or weakening of the heart muscle. Should I be treated for low diastolic blood pressure (DBP)?Most people with low diastolic blood pressure (DBP) do not display any signs and symptoms and, hence, do not require any treatments. However, symptomatic people
Health NewsMedically Reviewed on 10/5/2022 References Medscape Medical Reference PACE-CME What is a dangerously low diastolic blood pressure?A 2016 study that lasted more than 3 decades and involved more than 11,000 people found that a diastolic blood pressure below 60 mm Hg is dangerous. People with this level are 50 percent more likely to have heart damage. This is compared with those who have a low diastolic pressure level between 80 and 89 mm Hg.
Why would the bottom number of blood pressure be low?Cause of Low Diastolic Blood Pressure
Pregnancy and heart conditions, such as low heart rate, heart valve disorders, and heart failure, can lead to low diastolic blood pressure. Aging is another risk factor, as well.
Is 50 diastolic too low?A diastolic blood pressure reading of 50 mm Hg is too low. Once your diastolic number goes below 60 mm Hg, it can make you dizzy or lightheaded and consistently low diastolic blood pressure can lead to heart disease. Yes, a diastolic blood pressure reading of 50 mm Hg is too low.
What is the best bottom number for blood pressure?A normal blood pressure is at or under 120 systolic over 80 diastolic. If your blood pressure reading is at or under 120 over 80, you have healthy blood pressure and you can keep doing what you're doing.
