How low does your HEMOGLOBIN level have to be before you need a couple of units of  blood?

it depends on the situation.  if someone has a slow GI bleed, they can be asymptomatic and have hemoglobins as low as 5 or 6.  However if someone is acutely bleeding, a drop from 14 to 10 may cause dizziness and hypotension.  The biggest factor is if their heart rate is elevated, their blood pressure drops and they feel weak and/or dizzy.

blood cells have a life span of 100 - 120 days. Red cells that are transfused have been stored for up to 35 days in the blood bank. The blood donated will have been a mixture of cells between 0 and 120 days. Regarding replacement of your own blood then it depends how much blood you have lost. If you have been transfused to a decent level of Haemoglobin, then your bone marrow will replace your red cells as normal and whole bodies red cells will have been replaced within 120 days.

If the heamoglobin (HB) is 12 or over, you would need one pill of iron-based pill, if less than 11, then two pills daily, keeping in mind that you would need a blood test to test the HB ratio monthly.

That is weird, my friend and I were discussing that yesterday. She had been to the doc and he said that the blood bank loves her blood, she is 0 neg. too. She told me that anyone can get her blood, but she could only have 0 neg. herself. I never knew that! I have no idea what type I am, but I will find out now. Thanks for reminding me to do that!

if it stays low from what I understand from family members being anemic your body could go into shock and that can bring on other illnesses.  being anemic is not a good thing because your body needs the iron to fight off infections and viruses.  That is why people who are anemic if they do not take care of themselves they are always cold and they are always sick with the flue or a cough.

Call your local health department and ask them about low income/free clinics to provide you with health care. You probably need some iron from losing alot of blood but you definitely need a doctor. If they don't provide you with any help call a local hospital and ask for their social services department and talk to them about free/low income clinics/doctors. Good luck.

blood is required in the liquid phase and required immediately. some rare blood types are frozen but the recovery from the frozen state is quite poor and takes sometime. most of the blood collected is used, but there is always a need for more.

Males have up to 6 units of blood and females have up 5 units of blood, but I think that is all humans, not just Americans. HA HA HA HA !!

Yes, your Doc is right. You do have a low HB level. Take Zincofer as prescribed, your doc did go to medical school to know what he's talking about. While you should not have trouble conceiving, you should first try to get your HB level up( This is in the best interest of the health of your baby and you). Please don't go on any diet, it is just a bunch of crap. Just eat properly, with adequate(not excess, don't go over board) amount of greens.The iron tablets will work better than anything else.just relax and remember this will take time. And no you don't need blood transfusion , unless you suffer from secondary symptoms.

Iron is necessary to make hemoglobin, the substance that carries oxygen through your blood to all the cells in your body. Hemoglobin is what makes red blood cells red. With insufficient iron, and therefore not enough hemoglobin, red blood cells become small and pale and don't carry enough oxygen. You may have heard the phrase "tired blood." This really means blood that is low in iron and that can't carry enough oxygen to vital organs and muscles. "Tired blood" results in a tired body. \n\nIron is needed not only for blood, but also for brains. Neurotransmitters, the neurochemicals that carry messages from one nerve to another, require sufficient iron to function properly. A person with an iron deficiency may have a tired mind as well as a tired body.

300-450 white cell is a normal reading even if you get your blood done. Your body replaces the missing ones in a matter of hours. Our body is capable of amazing feats.

In the UK if your taking insulin, then you will not be able to give blood. This restriction is because concern about the health of the blood donors, \n\nIn the US To give blood for transfusion to another person, you must be healthy, be at least 17 years old or 16 years old if allowed by state law, weigh at least 110 pounds, and not have donated blood in the last 8 weeks (56 days). "Healthy" means that you feel well and can perform normal activities. If you have a chronic condition such as diabetes or high blood pressure, "healthy" also means that you are being treated and the condition is under control. \n\nInsulin\nThose who since 1980, received an injection of bovine (beef) insulin made from cattle from the United Kingdom are not eligible to donate. This requirement is related to concerns about variant CJD, or 'mad cow' disease. Learn more about variant CJD and blood donation.

As far as I know, no.\n\nHowever, it is necessary for a pregnant woman to keep her haemoglobin level ok, because if not, she will have anemia and she can't provide her baby with enough oxygen.\n\nCalcium is necessary too, so that bones of the baby form well.
