What classifiys as a low blood pressure?

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.

it depends on the situation.  if someone has a slow GI bleed, they can be asymptomatic and have hemoglobins as low as 5 or 6.  However if someone is acutely bleeding, a drop from 14 to 10 may cause dizziness and hypotension.  The biggest factor is if their heart rate is elevated, their blood pressure drops and they feel weak and/or dizzy.

Low levels could indicate anemia.\nhttp://www.lymphomation.org/CBC-blood-counts.htm\n\nHCT - Hematocrit  (he-MAH-to-crit)\nRef.  Range 38.5 - 49.0%\nPercent of  your blood that is occupied by red blood cells. Good indicator of anemia.\n\nHGB - Hemoglobin  (HE-muh-glow-bin)\nRef.  Range 13.2 - 16.9\nHemoglobin is a protein used by red blood cells to distribute oxygen to other tissues and cells in the body.  Low levels indicate anemia.\n\nRBC - Red blood cells (erythrocytes - eh-REETH-ro-site)\nRef.  Range 4.20 - 5.70\nCells that deliver oxygen throughout the body and make blood look red. A low RBC can indicate anemia, which can lead to fatigue.\n\nRDW - Red Cell Distribution Width\nRef.  Range 11.0 - 15.0\nMeasures the range of sizes of red blood cells in a blood sample. RDW results are often used together with MCV results to determine possible cause of anemia when anemia is indicated by other test results.\n\nMPV - Mean Platelet Volume\nRef.  Range 7.5 - 11.5\nMeasures the average volume (size) of your platelets. Higher-than-normal MPV is associated with an increased risk of heart attacks and stroke.\n\n"Anemia"\nhttp://kidshealth.org/parent/medical/heart/anemia.html\n\n"Anemia, one of the more common blood disorders, occurs when the number of healthy red blood cells decreases in the body."

The top number (systolic) is the maximum pressure in the artery (when the heart beats). The bottom number (diastolic) is the lowest pressure in the artery (when the heart is at rest). "Too low" is determined by if it affects the person. Low blood pressure can mean dizziness or fainting. If that's not a problem, then it's not too low. The main problem with blood pressure is when it gets too high, because then it affects the arteries, which can lead to other problems. As long as he's feeling well, that's excellent blood pressure for someone his age.

You have a symptom, only a doctor could tell you the correct diagnosis.\n\nThat could be a lot of things, like a stroke, stress, low pressure.

Personally for me, when my blood pressure is high....its hard for me to sleep, anxiety keeps me up, and sleep is horible. but when my blood pressure is low, usually I feel better and get a better nights sleep.

I also suffer from low blood pressue - lower than yrs actually.\n\nDo u have any sypmtoms of low blood pressure: dizziness, constant tiredness?  If not, then yr current blodd pressure should be fine.\n\nNormal is 120/80.  If u had to choose, low blood pressure wud be better to have than high blood pressure, which brings with it damage to coronary arteries, other arteries and subsequent heart disease.\n\nIf u do have symptoms of low blood pressue(mentioned above) u should visit yr doctor.  There are medicines u can take, but simply adding a LITTLE salt to yr diet will help.\n\nSalt helps u retain fluid, thus increasing blood volume and thereby increasing blood pressure.\n\nExcercise also helps increase blood pressure, and keeps yr arteries and heart in good shape!\n\nIf u decide to donate blood, inform the nurse/doctor present that u have low BP.

possibly circulation shutting down? lack of oxygen, lack of blood pressure? Depends what has failed.

Ya...it can be cured...low blood pressure i am not really sure...but concentrate on the medicine given by the doc...it shd work...

headache, weakness, fainting\n\nThe numbers for low BP differ between people but generally speaking BP numbers below 100/55 and pulse below 55 or so.\nIf you have low BP, drink lots of Gatorade to make sure you have enough electrolytes for proper heart function.\n\nhttp://www.nlm.nih.gov/medlineplus/ency/article/003083.htm

dizziness or lightheadedness when rising from lying to sitting position or when standing...not just like "ooh i stood up too fast" but even when doing normal activities. also feeling cold in the limbs, fingers, toes can indicate low blood pressure and/or poor circulation. weak pulse can also be an indicator because there is not enough blood to cause a strong heavy beat in the usual pulse points like the wrist or neck.

Blood 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).\n\nIn medicine, a person's pulse is the throbbing of their arteries as an effect of the heart beat. It can be felt at the neck, at the wrist and other places.\nPressure waves move through the blood vessels, which are pliable; it is not caused by the forward movement of the blood. When the heart contracts, blood is ejected into the aorta and the aorta stretches. At this point the wave of distention (pulse wave) is most pronounced, but relatively slow-moving (3 to 5 m/s). As it travels towards the peripheral blood vessels, it gradually diminishes and becomes faster. In the large arterial branches, its velocity is 7 to 10 m/s; in the small arteries, it is 15 to 35 m/s. The pressure pulse is transmitted 15 or more times more rapidly than the blood flow.\nThe term pulse is also used, although incorrectly, to denote the frequency of the heart beat, usually measured in beats per minute. In most people, the pulse is an accurate measure of heart rate.

People that faint in the face of danger, are suffering from a suddenly and significant drop in blood pressure.\n\nFainting is actually a valuable self protective response.When blood pressure drops this way, there is a chance the brain won't get enough blood, because it's at the highest point of the body. That's no good - your brain needs a steady supply of the oxygen the blood carries. So when your body can't get enough blood to your brain because of low blood pressure, it protects you by bringing your brain down to the blood. In other words, the purpose of a faint is to ensure a blood supply to the brain by bringing your head down to the ground, so your heart doesn't have to overcome gravity.

Have your blood pressure checked.

There are many things that determine your blood pressure, or the pressure of your blood within your arteries.  Here are a couple:\n\n* The ease of your blood passing through your arteries (or conversely the restrictions of your blood passing through...)\n* The permeability of your capilaries\n* The make-up of your blood (usually the amount of salts)\n* Your Heart and how hard it is beating\n* The amount of blood you currently have (If you lose a lot of blood, you will have low blood pressure - not what you want though)\n* Certain drugs can have other types of effects.\n\nJ
