What Causes Low Blood Volume
Low Blood Volume: Low blood volume (lv) can be caused by lack of intake, or loss of fluids. If one has a hemorrhage and losses a great deal of blood, that causes lv. If a person has severe diarrhea, lv can be consequence as well. Likewise, if a person is denied water, lv is a result as well. Lv can be a serious situation if it severe and acute. In that case, seek medical attention as soon as possible. ...Read more
Male 22 angiotensin II was 8ng/l and aldosterone 161 pmol/l i urinate a lot and have pots. Could this cause low blood volume?
Can't answer: Normal values vary from lab to lab. This question is complex and can't be answered in a vacuum. ...Read more
If someone had low BP due to dysautonomia, would aldosterone be higher to increase blood volume? In turn could cause a lower than normal potassium?
Sure: In pregnancy, your blood volume increases quite a bit. If you do not drink enough water or if you are anemic your blood volume may not increase. We will need to see the entire blood count report to give you proper advice. I suggest that you either ask your doctor to explain in more detail or get your records and do a virtual consult with us. ...Read more
Yes, but...: Your body will compensate only so long. If the "blood volume is low" otherwise known as anemia, this should be investigated. The younger you are (infants excluded) the longer you can tolerate this but at low hematacrit levels you will begin to have symptoms. Have your doctor do a cbc. ...Read more
Correlation yes, yet: variable overtime. If we bleed, internally &/or externally, then blood volume drops-Short Term & up to ~1/3 volume can be compensated for via venous constriction short term, without RBC count change. However, low intravascular volume immediately begins recruiting extracellular water from tissues back into vascular space gradually ?ing volume & ?ing RBC count over next many hours. Complex relation. ...Read more
Fludrocortisone increases blood volume, alcohol causes dehydration. Does this mean they will work against each other? Thus florinef (fludrocortisone) less effective?
Strange question: Why are you taking fludrocortisone? Do you know its mechanism of action? Did your doctor tell you what it is used for? The only reason I have EVER prescribed this drug is for idiopathic orthostatic hypotension, which I have NEVER seen in a 24 year-old. If your doctor has prescribed Florinef, ask him why he prescribed it. You shouldn't be combining alcohol with ANY prescription medication. ...Read more
Could fludrocortisone cause reflex bradycardia if blood volume increases too much increasing central pressures?
Theoretically: It is possible that you could get reflex bradycardia from volume increase but the amount of volume required to trigger this reflex would not be achievable with florinef (fludrocortisone) alone. Bradycardia is a common response in dysautonomia which florinef (fludrocortisone) is used for in treatment. I suspect the reflex bradycardia is actually the physiologic response from dysautonomia not volume overload. ...Read moreSee 1 more doctor answer
When i had bacteremia, the blood cultures also showed my blood volume was low. Did the infection itself affect the volume? Confused
Quite confusing...: Blood culture tests provide no information on whether a patient's blood volume is high, low, or normal. When it happens, low blood volume is reflected in a patient's symptoms and the course of her illness. Her various blood test results (not the blood culture) can suggest that blood volume was recently lowered due to her symptoms, but there is not a simple "blood volume lab test". ...Read more
Recent blood test shows low indirect bilirubin (.08)+increased blood volume (99.7)+increased hematocrit (47.2)+high WBC (14,200). Huh?
Uncertain.: The WBC is definitely high, but the HCT and MCV are borderline, and thus of uncertain significance. If truly elevated, the HCT could point to a primary or secondary polycythemia, an increase in the number of red blood cells. But this could also reflect mild dehydration, and given the borderline degree could be nothing. The high WBC is real. If you have no symptoms I would just repeat in 1mo. ...Read more
