Before i jump to the main topic i want to recall that not everybody can donate her/his blood. Why? Because there are risks of blood-borne infections. Blood-borne infection is infections that are transmitted through the blood. Due to the risks that may occur to the receivers, the donors will be given some confidential medical history paper to fill out. If the donors pass all the requirements needed then they can donor their blood. But if they do not pass even one of the requirements they have to look for the next chance or even do some medication if there’s infection in their blood before they can be the donor.
Despite health benefits of blood donation I mention above, blood donation also have side effects you should know before you go and generously donating your blood. You can pay attention on this information and be more prepare before you donate your blood.

It can drop blood pressure and make you feel dizzy. This effect is commonly occur to donors after donating their blood. You can lie down and rest if you feel dizzy. Then you will be offered refreshment to help you stop the dizziness. Usually it’s just temporary until your blood pressure is back to normal condition. If it continue please checked by paramedic.
A sudden drop of blood pressure can also cause chills. Your heart will take some time to supply fresh blood through you body. It can makes you feel chills and sweating beside dizzy and weak. To minimize this side effect you have to drink, eat well-balance meal, and getting enough sleep time before and after your blood donated.
Hematoma is a bruise caused by the inserted needle slips through the vein and cause local bleeding. Some bruise at the site where the blood was taken may occasionally exist. Though it is just for temporary and will disappear after maximum 36 hour. It is normal for bruises to spread before fading even if it may look dramatic. If you worry about your bruises you can treat it by compression on the bruises, rest, avoid heavy lifting, and rise your arm above the level of your heat while resting.
- A sore arm
If you feel your arm sore you can take acetaminophen or any pain reliever. You should avoid taking aspirin and iburofen such as motrin, advin, etc. as well.
Nausea can be triggered by few reasons. The reasons include feeling pain of venipuncture, when the donor seeing his or her own blood and seeing another donor unwell, when the anxiety and state of tension of undergoing the donation, etc. You can treat this effect with rest and try to feel relax.
If you feel nausea it is usually follow by vomiting. But it’s uncommon to vomit after the donation. It may be a severe complicated effect. You should ask the paramedic and rest well.
- Pain and Tingling
Pain and tingling may be a serious effect. If the donors feel pain or tingling in their arm into their fingers, they should call blood center paramedic or see a doctor.
If you have symptoms like a cold or flu (fever, headache, or sore throat) within four days after you donated your blood you must call the center immediately. You may need medical care.
It is normal to feel a little bit tired after donating blood because there’s less circulation of blood to the brain. But feeling fatigue is uncommon for donors. Though most of donors will be feel fine after donating. A small number of people will have these effect. If you feel fatigue and about to faint you should immediately lie down and rest. You will be better after some time.
Faint is frequently as side effects of blood donation, This effect can be occur if you stand up abruptly of if you have been standing for a long time after donating your blood. This also caused by the dropping pressure of your blood. If you feel like to faint you can lie down and elevate your legs, consume fluids and salty food (biscuits or meal), and squat as soon as you feel like to faint.
Bacterial infections may occur during the blood donation if the needle is not sterilized. If you feel ill before donating your blood you must tell the donor center so that the infection of your blood will not be transmitted to the donor’s receiver.
Those effects above is highly because a dropping in your blood pressure. It should be not a worrying condition though. For donors there are reactions of body’s tolerance during and after donating procedure. It may vary for everyone but the paramedic at the Blood Center will do things necessary if you undergo these effects. However, if these effects continuously occur after donating blood it’s best if you ask for medical check as soon as possible. There may be something wrong in your blood system that effect your health. Just in case.
But overall major effects are rarely occur. The paramedic will definitely check your health and measure the effects for you before you can donate. You can be relax.
