During the circulation of blood, the blood pressure drops slowly as it moves away from the heart through arteries, and toward the heart through veins.
Diastolic blood pressure varies depending on the activity, surrounding temperature, diet-taken, state-of-mind (emotional), physical posture and medication used.
What is diastolic blood pressure?
Diastolic blood pressure is minimum pressure in the arteries, which generates near the beginning of the cardiac cycle when the ventricles are filling with blood. That is the heart is relaxing; the pressure number is lower than systolic.
As said before blood pressure reading is representing by two numbers one over the other, for example, 110 over 70 in millimeters of mercury (mmHg). The bottom number is diastolic blood pressure reading, and it is the minimum pressure in the arteries when the heart is at rest.
Importance of Diastolic Blood Pressure
Heart pump’s blood into your blood vessels, enough diastolic BP is requiring to maintain blood flow to all parts of your body. Blood vessels away from the heart, are branched as smaller tubes, one may go to brain and other to kidneys. Diastolic pressure maintains blood flow to all branches to provide oxygen and nutrients for every body cell and removes waste.
Diastolic blood-pressure readings are specifically important in the monitoring of the blood pressure in younger individuals.
High and low diastolic blood pressure
If the diastolic number is low, your body cells unable to get required oxygen and nutrients. This may even lead to cell death. If a number of less than 60 mmHg are, considering as a low diastolic number called hypotension.
If the diastolic number is high, your blood vessels are becoming harder (start losing elasticity) and scars. This may cause blood vessel blockage or rupture; this leads to organ damage or even failure. A number more than 90 mmHg are considering as high diastolic BP called hypertension.
