What Is The Cause Of Low Blood Pressure
Hypotension is defined as "low blood pressure". Blood pressure is measured as two numbers and expressed as systolic blood pressure (sbp) / diastolic blood pressure (dbp). The sbp is the pressure that is generated when the heart squeezes. Dbp occurs when the heart relaxes. 120/70 is considered normal in adults. Less than 100/60 (of either number) can ...Read more
? : I'm not clear about your question - you required 2 blood transfusions? Blood loss will cause both low blood pressure and may require blood transfusions. Are you bleeding? Alternatively, nearly any chronic disease will cause anemia and, if you're ill and not eating and drinking properly, can also result in low blood pressure, especially if infection is present. ...Read more
Mostly Genetics: The most common cause is called essential hypertension- 90% is of this type. This type is mostly from genetics. Some people are born with an inherent sensitivity to salt. So there is an environmental (diet, stress) component in some. Other causes include a narrowing of the arteries supplying the kidneys called renal artery stenosis. Other causes are hormonal, obesity/metabolic , or certain meds. ...Read more

Several: The inherently elevated Insulin levels of Insulin resistance may promote a reactive hypoglycemia following a high carb snack or meal, particularly if devoid of significant protein. Otherwise, treatment with Insulin and oral medication like sulfonylurea receptor agents are known for causing hypoglycemia also by increasing Insulin levels. ...Read more
It depends upon....: The blood counts to which you are referring. If you mean anemia, the overwhelmingly most common reason for a low rbc count in the us is fe deficiency, in part because of our typically fe poor diet, and exacerbated by a monthly blood loss in women. Fe deficiency, however, is due tof an underlying primary problem to be discovered and corrected. For low WBC count, viral suppression is most common. ...Read more
Not directly related: The blood level of sodium is often high in the face of dehydration and this may or may not correspond with a change in blood pressure. If one is volume depleted, the blood pressure may be low. However, some may have severe weakness of their heart muscle and the blood pressure and the sodium may both be low. It is important to correlate the medical issues involved to interpret these levels. ...Read more
Not many: Not many and not that important. Most common reason would be aortic insufficiency (leaky aortic valve). Other than that, there are artifacts (errors) taking the blood pressure in someone with rigid arteries that will make diastolic BP artificially low. True diastolic low BP (not related to leaky valve) requires NO treatment ...Read more
Blood pressure is a measurement of the force placed on the blood vessels and is comprised of the "systolic" pressure (the top number on a blood pressure meter) which is the peak pressure when the heart is pumping, and the "diastolic" pressure (the bottom number on a blood pressure meter) which is the pressure during the resting phase ...Read more
Abnormal blood pressure is a symptom in which a person's blood pressure is much higher or much lower than it should be for his age and body size. If either the systolic (upper number) pressure or the diastolic (lower number) pressure is not in the normal range, then the ...Read more
