Low Blood Pressure
If 1000 people had their readings measured then we might expect to find a spread of readings. These might range from as high as 200 / 120 down to 80 / 50 with most people clustering around a level of around 130 / 85. Most of these people would have no symptoms of any kind – no matter what their reading actually was. Even those with obviously low numbers would be free of any symptoms usually. The answer to whether it is normal or abnormal to have a low reading depends on what your own typical or average BP level is.
If, for the whole of your life, you’ve always had readings of around 90 / 50 – then without doubt you have “low blood pressure” but there is truly nothing wrong with you or with your reading. You should be pleased that your risk of stroke or heart attack will be much less than many others. You are not likely to experience any symptoms from your “low BP.” Putting it simply – your level is normal for you and needs no investigation or treatment. This kind of “normal low BP” will not cause you any symptoms and will need no treatment. It’s just part of you and how your system works.
If your BP is usually around 130 / 80 and suddenly or gradually drops to a level around 90 / 50 then it’s very likely that you will become aware of symptoms related to this change. As in the above example you have “low blood pressure” but in this instance it is not normal for you to have readings this low. You may need to see your doctor for tests because it’s quite likely that some other disease or perhaps a medication has caused your reading to drop. Someone who develops low numbers like this will often experience symptoms such as those listed below.
The symptoms of an abnormally low BP level can include: Feeling light headed, feeling dizzy, being tired or feeling fatigue on exertion, fainting, transient blurring of vision, or transient confusion. All these low blood pressure symptoms will resolve if the blood pressure returns to normal. The followings are among the many possible causes of low blood pressure when it is abnormally low: Medications for anxiety, medications for blood pressure, heart medications, diuretics or “water tablets” and some anti-depressant medications. Other medication related causes are painkillers and alcohol – particularly if these twos are mixed Non medication causes of include dehydration, heart disease and heart valve disease, recent heart attack, changes in heart rhythm, bacterial infection in the system, kidney diseases, diabetes mellitus and hemorrhage or bleeding.
