What can cause low blood volume?

What can cause 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

My OB told me I had low blood volume what does this mean?

My OB told me I had low blood volume what does this mean?

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

Can you still have low blood volume if blood pressure is normal?

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

Is there correlation between low blood volume and anemia? Can you clarify?

Is there correlation between low blood volume and anemia? Can you clarify?

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

When i had bacteremia, the blood cultures also showed my blood volume was low. Did the infection itself affect the volume? Confused

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?

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

Could 6 tubes of blood draw over 3 weeks quickly worsen anemia symptoms of a severely anemic person (half the blood volume, half the rbc)?

Could 6 tubes of blood draw over 3 weeks quickly worsen anemia symptoms of a severely anemic person (half the blood volume, half the rbc)?

No: An adult has roughly a gallon of blood flowing through their veins (and arteries and, to a small extent, the lymphatic system). They would have to be very large tubes. I would have to assume that they are drawing blood because someone is trying to identify a cause of illness and that illness is also making the person anemic. ...Read more

My body temp ranges from 95-97.7 lately; feel feverish when v low. 21, v ill with pots-like symps since flu in feb (tilt-table test end of july). Can normal hospitals do blood volume tests?

Need to re-evaluate: Low body temperature can occur with low vit d3. Check 25-oh vit d3 levels not 1, 12 vit d3. Propanolol and bisprolol can lower BP too much and cause poor circulation. Alternate approach to pots is drinking electrolyte rich water, eating 6 equal meals, and avoiding high carb meals. Will power training by kelly mcgonigal very helpful. Exercises done lying down like the core program helps too. ...Read more

I am on fludrocortisone to retain more water and blood volume for low blood pressure, does this mean it takes longer to dehydrate due to more volume?

I am on fludrocortisone to retain more water and blood volume for low blood pressure, does this mean it takes longer to dehydrate due to more volume?

No.: Fludrocortisone is taken to retain salt AND water and to prevent you from having symptoms related to lack of blood volume.. Salt and water make up a good part of your blood volume. When your blood volume is low you are dehydrated. It should now take you longer to show symptoms of dehydration than before you took the med. ...Read more
