High Diastolic Blood Pressure: What Does it Mean?

High diastolic blood pressure or diastolic hypertension just means a blood pressure measurement of 90 and above when the heart is in relaxing mode for just a quarter of a second.

There are two numbers to blood pressure readings one is the systolic blood pressure when the heart is on a banging beat pushing blood around the body and the second is the diastolic, which this article is about.

Since I discovered I had hypertension all those years back (about) I have been gathering information on the silent killer from all sources and most from my doctor, so I can keep one-step a head of its deadly effects. I have even taken a break from using some of the best budget 3D printers that I was accustomed to in my art hobby as most of my time is now spent on researching HBP.

When I got more acquainted with my condition I asked my doctor what he was listening to when he took my blood pressure? He said he was listening to 2 sounds the heart makes when beating and when relaxed. Being ignorant I said I thought I had High BP?

He said yes you have, but it is broken up into two numbers in my case both were high the systolic some where between 160/180 top number, and the diastolic bottom one between 90/100.

He said the device he uses is called a sphygmomanometer, which he inflates around the arm, to a degree it feels like the blood vessels are about to burst.

After required inflation he slowly releases air until he picks up the distinct sounds between systolic and diastolic. As I mentioned above it’s always high up the blood pressure chart for me.

Diastolic number can change a lot during the day because of:

  • Level of exercise
  • Posture
  • Nicotine use
  • Amount of stress you are exposed to

To avoid high diastolic blood pressure take a closer look at your diet, overall health, family history of HBP, heart diseases and lifestyle. Understanding all these factors can go a long way in bringing blood pressure down to normal readings.

Pre-programmed route of blood around the body

As the blood vessels travel from the heart they gradually decrease in size and branch off to the liver, kidneys and lungs and so on. In normal diastolic pressure there is enough pressure to send blood to all parts of the body, which works out just fine.

But for someone suffering from diastolic hypertension it’s a bad thing as the small vessels that supply blood to the vital organs are affected the most by such high pressure of blood.

Elevated diastolic pressure can cause hardening arteries and eventually become less elastic and scarred and are prone to break a lot easier and get blocked.

As a person gets older the arteries go through this gradual deterioration process, but if diastolic hypertension is thrown into the mix, the process speed up at a greater rate.

Maintaining normal blood pressure is vital for someone wanting to reduce the risk of blood vessel and organ damage, stroke or heart attack. Here are some of the high blood pressure numbers to look out for in diastolic mode.

  • Someone with a diastolic blood pressure of 81 to 89 has a health condition known as pre-hypertension.
  • About 2% of patients with elevated blood pressure don’t seek help to reduce blood pressure until the symptoms are severe.
  • At this stage the disease is called malignant hypertension, diastolic blood pressure at 140 and above at times.


The main symptoms are:

  • Nausea
  • Light-headedness
  • Frequent headaches

When it gets to this stage it is important to see your doctor, so he can assess your blood pressure readings. This article is for information purposes only; always consult your doctor regarding blood pressure issues.
