PCV is the volume percentage of red blood cells in a mammals blood. When one's PCV is low, the cause is generally anemia.
If you have a low blood pressure, low hematocrit and hemoglobin, you need to have a blood transfusion.
Yes, low blood pressure may sometimes result in headache.
A lack of iron tends to result in low blood count.
Low iron in the blood causes Anemia.
my polys is low at what causes?
In dehydration, the volume of plasma in the blood decreases due to the loss of water, while the number of red blood cells remains relatively constant. This results in a higher concentration of red blood cells per unit volume of blood, leading to an increase in packed cell volume (PCV) or hematocrit. Essentially, dehydration causes the blood to become more viscous and concentrated, which elevates the PCV.
Bleeding A Lot Probably
No, it causes low blood pressure
what causes hyponatremia?
The most common low blood pressure symptoms is low sugar levels. Weight loss, headaches, dizziness and there are other symptoms that causes low blood pressure level.
high potassium causes arrhythmias and the arrhythmias that it causes can reduce blood pressure causing someone to collapse.
PCVAlso known as: Packed cell volume; haematocritRelated tests: Full blood countThis test is used to evaluate:anaemia (decrease of red blood cells),polycythaemia (increase in red blood cells),dehydration,blood transfusion decision, andthe effectiveness of those transfusions.The PCV is normally requested as a part of the full blood count (FBC). It is also repeated at regular intervals for many conditions, including: the diagnosis of anaemia,the treatment of anaemia,recovery from dehydration, andmonitoring of ongoing bleeding to check its severity.A decreased PCV indicates anaemia, such as that caused by iron deficiency. Further testing may be necessary to determine the exact cause of the anaemia. Other conditions that can result in a low PCV include vitamin or mineral deficiencies, recent bleeding, cirrhosis of the liver, and malignancies.The most common cause of increased PCV is dehydration, and with adequate fluid intake, the PCV returns to normal. However, it may reflect a condition called polycythaemia vera-that is, when a person has more than the normal number of red blood cells due to a problem with the bone marrow . More commonly polycythaemia is a compensation for inadequate lung function (the bone marrow manufacturers more red blood cells in order to carry enough oxygen throughout your body).Pregnancy usually causes a slightly decreased PCV due to extra fluid in the blood. Living at high altitudes causes an increased PCV - this is your body's response to the decreased oxygen available at these heights.
