The Disadvantages of Donating Blood
There’s no doubt that donating blood can do a lot of good: Donating just one pint of blood can save more than one person’s life, according to the American Red Cross. About 36,000 pints of blood are needed every day in the United States, and 6.8 million people donate a year. But blood donation isn’t without its disadvantages. Each donor is given a mini physical examination, but there are still some minor side effects that could occur. These include:
- continued bleeding
- dizziness, lightheadedness, and nausea
- physical weakness
Donating blood is a safe process, but there are some things you should know before you donate. Here’s a closer look at the disadvantages to consider before donating blood.
When you donate blood, you sit or lie on a reclining chair with your arm extended on an armrest. A healthcare provider will place a blood pressure cuff or tourniquet around your upper arm to fill your veins with more blood. After cleaning the skin on the inside of one of your elbows, the provider will insert a sterile needle attached to a thin plastic tube and blood bag into one of your veins. The needle is kept in your arm for about 10 minutes, or for the duration of your blood donation.
When a needle pricks a vein, there’s always a chance that some bruising will occur around the site where the needle was inserted. For that reason, bruising is common among blood donors.
Bruises range in color from yellow to blue to purple. Mild to moderate bruising is usually not something to worry about. If you experience bruising, apply a cold pack to the bruised area every few hours for several minutes during the first 24 hours after you donate blood.
When a blood donation is complete, a healthcare provider will remove the needle from your vein and place a bandage on the needle site. They will wrap your arm with a dressing. The bandage and pressure of the dressing is meant to stop the blood flow out of your vein. Your nurse will instruct you to keep your bandage and dressing in place for at least four to five hours to ensure bleeding is stopped.
Sometimes bleeding still occurs after the bandage and dressing are kept in place for several hours. In this case, it’s important to place pressure on the needle site and keep your arm raised above your heart for three to five minutes. If the bleeding doesn’t stop after that time, you should contact your doctor.
