Is a low diastolic blood pressure reading dangerous?

It depends...What is the systolic reading?  Do you have negative symptoms like dizzyness?  Joggers, athletes...people who do arobic exercise may indeed have lower BPs compared to standard and this is good.  The "mean" blood pressure" is the systolic and diastolic added together and divided by two.  BP of 120/80 has a MBP of 100.  The average acceptable MBP is 100, however the healthy normal for some may well be lower.  The best way to answer your question has much to do with your own medical history and the incclusion of possible negative symptoms.

the above is mostly correct. Ideal BP would be 115/75 according to JNC 7 guidelines.  Systolic below 80-90 or diastolic below 60 or so would indicate low BP. However everyone is different and some people have BP's of 90/60 and are very healthy-low is verified by lower than normal BP with symptoms of hypotension Such as Lightheaded, dizzy, loss of consciousness 'rapid heart rate in attempt to counteract the low BP, volume depilated either dehydration or loss of Blood, etc.\n\nBP's stated above are in mmHg (millimeters of mercury) the common  standard in U.S.

No.  It is high.  \n\nYour top number should be 120 or less.  Anything between 120 and 140 is "borderline" high.  Yours is above that, so you are high.  Your bottom number should preferably be 80 or below.  Up to 90 is borderline.  Again, you are above that.\n\nBut one test doesn't prove anything.  People vary from day to day and from time to time within a day.  Several readings are necessary before your doctor can make any diagnosis or recommend any treatment.  \n\nIt is also important to get your blood pressure taken by a professional.  Don't rely on the machines you find in drug stores and supermarkets.  If your reading of 148/96 did not come from a doctor or nurse's blood pressure meter, then it is time to get an accurate reading before you start to worry too much.\n\nGood luck.  Hi blood pressure  is a funny thing.  It doesn't hurt, so it is easy to ignore or even forget about entirely.  But it can *kill* you just the same.  On the other hand, treating it is usually fairly easy, assuming you get to it before it does any damage to your heart, your eyes, or your kidneys.  So don't wait around.  See a doctor.  Good luck!!

because these are the only two measurements done with a routine manual blood pressure reading.  now if on a blood pressure monitoring machine, there is a mean or average blood pressure.  however, the basics are the top number or systolic and bottom number or diastolic.  the systolic is the heart when working or contracting; the diastolic is the heart at rest.  a high diastolic is more significant due to the fact that a hi diastolic creates more pressure in the arteries to move the blood to vital organs.

My honest feeling is the BP readings taken are not correct. Such high and low changes are next to impossible. You need to tak him to a cardiologist for evaluating the position and treating him. Blood Pressure - high or low - is termed as silent killer. Please see the doctor without delay. \n\nNow a short note from Wikipedia about BP for your inforamtion -\n\nBlood pressure is the pressure exerted by the blood at right angles to the walls of the blood vessels. Unless indicated otherwise, blood pressure refers to systemic arterial blood pressure, i.e., the pressure in the large arteries delivering blood to body parts other than the lungs, such as the brachial artery (in the arm). The pressure of the blood in other vessels is lower than the arterial pressure. Blood pressure values are universally stated in millimetres of mercury (mmHg). The systolic pressure is defined as the peak pressure in the arteries during the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle). The mean arterial pressure and pulse pressure are other important quantities.\n\nTypical values for a resting, healthy adult human are approximately 120 mmHg systolic and 80 mmHg diastolic (written as 120/80 mmHg), with large individual variations. These measures of blood pressure are not static, but undergo natural variations from one heartbeat to another or throughout the day (in a circadian rhythm); they also change in response to stress, nutritional factors, drugs, or disease-

Low BP lower BP than the ideal 80/120.Low BP is common in athletes to some extent.What you say seems to be state of moody or depresion state.This may not be due to low BP.If you suspect low BP better check up with a doctor and take his advise.Becuse low BP is dangerous as high BP.\nIf you are just moody only ,develop friendship,cultivate habots of reading listening to music or atart a hobby.You may not require an anti depressant if you do these simple things

Anything below 60 is considered low.\nChronic low blood pressure can lead to life threatening Deep Vein Thrombosis(Blood Clots).

It's not really bad, actually the normal range is:\n100/60 - 140/90, so it's just your bottom number (dyastolic) that's high on this reading and I imagine if you were to check it again it would probablly go down. You would tend to be more concerned if during a 2 week period it stayed at this level most of the time.

yes honey thats fine... if thats normal for you.. im female and 21 and mine is like 98/59  some of us just run a lil lower than others.. nothing to worry about... my mom is 52 and hers is really low too...  just make sure especially as u get older when u go to the dr if your blood pressure is alot higher than that.. but still considered in the normal range.... tell your dr that your normal is 109/61...\n\nnothing to worry about!

could be several things\n\nhigh blood pressure-when your blood pressure gets to high-your body's autoimmune response is to try and shut itself down for protection. this means causing severe dizziness,faintness,complete loss of consciousness, chest pain,numbness,and blurry vision\n\nlow blood sugar-when the body's blood sugar gets too low-one can have feelings of extreme weakness or fatigue,dizziness,passing out,breaking out into sweats,confusion or disorientation.\n\npanic/anxiety attack. symptoms of these are:\n\n-overwhelming feeling of panic ( like you are going to die)\n-chest pain/tightness\n-dizziness or faintness\n-confusion or disorientation\n-blurry vision\n-heart palpitations\n\nany one of these situations can require immediate medical attention. but first try these things\n\n-lie down in a dark,quiet,and comfortable room\n-place a cold washcloth on your forehead\n-take slow,deep breaths and try to focus on relaxing\n-have someone get you something cold to drink or get it yourself before lying down. take small,frequent sips\n\nrest for about 20-30 mins. if you are still having the same symptoms have someone take you to the emergency room. if there is nobody available to drive you-call 911 and have an ambulance come get you. since you are having vision problems-it is not safe for you to drive.

Yes, this is a good blood pressure.  normal range is between 100/60 and 120/80 approximately.  The top number is the pressure when the heart is squeezed during a beat and all the blood is in the vessels.  The bottom number is the pressure when the heart is relaxed during a beat and blood fills the heart, so less is in the vessels.

i am a nurse practitioner. something that could be going on is that this BP reading is TOO LOW for this person. they need to see a healthcare professional and be thoroughly evaluated. They will ask questions about normal BP readings for this person, risk for strokes, risk for clogged arteries, and even evaluate for something as simple as excess fluid in the ear. Only someone seeing this person in real life can help well.

With that blood pressure, I wouldn't worry at all.\n\nOnly once it goes toward 90 for the lower value, you might want to watch out. Not sure about a good indicator for the higher value, probably about 150/160 or so..\nSmoking surely doesn't really help in general, as such also for the blood pressure. So if you wanna do something good for your health, quit smoking...\nIf stress is a factor, I would have a good recommendation from my own experience.

Was this a "self test" or one supervised by a doctor or cardiologist?  If it's a self test I would advise you to see a doctor before getting on a treadmill again.  In fact, see a doctor anyway.  That's a very high blood pressure.  An increase in diastolic blood pressure of more than 10 mmHg (optimal is <120) during or after exercise represents an unstable form of hypertension, and may be associated with coronary artery disease.  At 236 you could be classified as well above third stage hypertension.  Really, see a doctor.

According to the site listed in sources:\n\n\nHow does a blood pressure gauge (sphygmomanometer) work? What exactly is blood pressure?\n &#92; \n     \nYour heart is an amazing pump. It works reliably for decades, and it safely pumps blood -- one of the trickiest liquids around. In the same way, your blood vessels are pipes. They take the output from the pump and distribute it throughout the body. A blood pressure gauge is simply a way to measure the performance of the pump and the pipes. \nThere are two numbers in a blood pressure reading: systolic and diastolic. For example, a typical reading might be 120/80. When the doctor puts the cuff around your arm and pumps it up, what he/she is doing is cutting off the blood flow with the pressure exerted by the cuff. As the pressure in the cuff is released, blood starts flowing again and the doctor can hear the flow in the stethoscope. The number at which blood starts flowing (120) is the measure of the maximum output pressure of the heart (systolic reading). The doctor continues releasing the pressure on the cuff and listens until there is no sound. That number (80) indicates the pressure in the system when the heart is relaxed (diastolic reading). \n\nIf the numbers are too high, it means that the heart is having to work too hard because of restrictions in the pipes. Certain hormones, like adrenaline (which is released when you are under stress) cause certain blood vessels to constrict, and this raises your blood pressure -- if you are under constant stress, your blood pressure goes up, and it means that your heart has to work too hard. Other things that can increase the blood pressure include deposits in the pipes and a loss of elasticity as the blood vessels age. \n\nHigh blood pressure can cause the heart to fail (from working too hard), or it can cause kidney failure (from too much pressure).
