Blood

Blood is a bodily fluid consisting of plasma, blood cells, and platelets that is circulated by the heart through the vertebrate vascular system, carrying oxygen and nutrients to and waste materials away from all body tissues. In many species, it also carries hormones and disease-fighting substances. In this category, you will find questions about the blood in your body, including blood types, blood diseases, and the function of blood.

Is it ok when having a nose bleed for blood clots to come out?

User Avatar
First, the fact that you are having nosebleeds may not be a very good indication to begin with. Nosebleeds are often caused due to damaged mucus membranes. The problem with having your mucus membranes damaged is that there is a possibility that you can develop nasal polyps. This is not a nice condition, as nasal polyps are growths inside your nose that can cause a lot of pain and, in the more severe cases, even change the shape of your face in that nasal area. The blood clots simply mean that your blood is drying within the nasal passage or even in the sinus cavity. I would like to know the answer to this question also. I had a very large blood clot that I pulled from my left nostril. Only one nostril was bleeding and stopped soon after. My kids have the same problem. I don't see any answers posted, but this must be fairly common if there are multiple posts. When your nose bleeds, the blood clotting is what eventually stops the bleeding. I am not a doctor, but it seems logical that you would see blood clots if you didn't allow the clot to stabilize and harden before blowing/picking your nose. your right the blood clots are just the blood stopping the flow it is ok to see them but if you do see them stop blowing or it wont clot and it will keep bleeding This can be caused by the blood congealing in your nasal carriageway and coming out in clots. But see your doctor if you are concerned.

What should a normal white cell blood count be?

User Avatar
White blood cell count (WBC). The number of white blood cells in a volume of blood. Normal range varies slightly between laboratories but is generally between 4,300 and 10,800 cells per cubic millimeter (cmm). This can also be referred to as the leukocyte count and can be expressed in international units as 4.3 - 10.8 x 109 cells per liter.

Can low hemoglobin cause muscle pain?

User Avatar
Yes, low hemoglobin can cause muscle pain. Hemoglobin is a protein and is attached to red blood cells. Its job is to carry oxygen to the body's tissues. Without oxygen the tissues (including muscle) experience ischemia which is painful. Ischemia is what causes the pain a person has when they have a heart attack, for instance. So if a person's red blood cells are not carrying oxygen (because their hemoglobin levels are low enough), they would have muscle pain.

What is the reason for low ESR in blood?

User Avatar
Broadly, causes of Low ESR is less production of red blood cell (RBC) . Indeed, the most common cause of less ESR is blood loss, but this usually doesn't cause any lasting symptoms unless a relatively impaired RBC.

What does a 314 white blood cell count mean?

User Avatar
It would be helpful to know what the units of measure are. In hematology, the reference range for a WBC is 4,500-11,000/mm3 ; however, the count is usually reported out in SI units ( for example, 4.5 x 109 /L) or Conventional Units (4.5 x 103/uL). So, on a lab report, a range of 4.5-11.0 is the normal range using these units of measure. If your report is using the standard units of measure, then a WBC of 314 is considered a "panic value". Extremely high. This could be due to several different processes, such as leukemias, severe infections (though this is still high even for a severe infection), and a handful of other conditions. Only your physician, taking all results and factors into consideration, can tell you where the problem lies.

Deficient blood supply to the myocardium?

User Avatar
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.

98 over 50 bp normal for a blood pressure?

User Avatar
This is a normal blood pressure if you are very athletic and/or are younger than 20. 98 is considered a normal systolic number, while a diastolic number of 50 is pretty low. This was my blood pressure yesterday and I did some research on it. http://www.vaughns-1-pagers.com/medicine/blood-pressure.htm has a really good chart about ranges of blood pressure

What color is oxygen-rich blood?

User Avatar
When blood cells have oxygen they are red, when they have no oxygen they are a darker shade of red. The more haemoglobin the blood contains the more oxygen is going to attach to the iron which is the most important element of the haemo-globin.

What to do if blood is too thick?

User Avatar
Drinking more water will thin the blood to a degree. If you feel there is a real problem, you should head in and get a quick test from your doctor. If there is a serious issue with the "thickness" of the blood, there are several things your doctor can do for you. One common measure taken is to put the patient on blood thinners. These are administered through close medical supervision. They can be in pill or IV form depending on he seriousness of the problem.

Is 11.3 a high white blood cell count?

User Avatar
The normal white blood count for the general population is around 7-8. So 11.3 is slightly high but not by much. You should go to your doctor and see what your baseline is. You MIGHT be one of those people who have a slighlt high count but it's normal for you. If you are worried you can ask your doctor to see a hematologist. Also if you have been taking meds, certainones like steriods can raise your count.

How much blood can someone lose before fainting?

User Avatar
The average healthy person has approximately 6 litres / 12 pints of blood - loss of one third, (1/3), of the total blood volume is fatal. Therefore I would say that a loss of about a litre / 2 pints would render a healthy person unconscious.

Do you have to fast for an A1C blood test?

User Avatar
No. The A1C test measures the amount of glucose bound to hemoglobin in the red blood cells. This binding process is related to the concentration of glucose present and the time of exposure. New cells are constantly created to replace old cells that are removed. Thus, the test meaures an average value of the glucose exposure over the life of the red blood cell (about 4 months). So, a one-day change, due to fasting for example, represents only a small change (one day in 120 days). For convenience, the doctor may have A1C run on blood drawn at the same time for other tests that DO require fasting. But, the nature of A1C should not require it.
