After giving blood, you need know how long it takes to recuperate after giving two units of red blood cells? It’s critical to know what to do following a blood donation in order to get back to normal as quickly as possible.

Donated blood and its components are essential for the survival and well-being of millions of people all over the world. Hemoglobin is a protein found in the hemoglobin-containing red blood cells. Oxygen is delivered to every part of the body via this hemoglobin. Obviously, oxygen is essential for life.

Red blood cells (RBCs) create 20 million red cells every second in your body’s 25 trillion RBCs.

Your red blood cells will take around two months to recover after a double red cell donation. Avoid strenuous physical activity, such as running a marathon, after donating blood. As the amount of red blood cells in the body decreases. Running or working out requires a lot of oxygen, which is carried by your red blood cells.

What Is Power Blood Donation?

The term “power blood donation” refers to the practice of donating double red cells. Two units of red blood cells must be donated in a single session to complete the procedure. Red blood cell donation equals 400ml RBCs if you donate two packets of RBCs. One contributes the same number of red blood cells as in four whole blood donations in a double red cell donation.

Double red cell donation is permitted for those with a certain blood group. O, A negative, and B negative are the three blood groups. Women who want to donate double red cells should weigh at least 150 pounds, while men who want to donate double red cells should weigh at least 130 pounds.

Be sure to eat a regular meal and drink enough of fluids before donating your organs. The blood collected from the arm vein is used to energize red cell donations. The blood from your arm will flow into the machine via a mechanical mechanism. Components of blood are separated in this machine.

The other blood components are safely returned to the body, mixed with saline, in the same vein after two units of red blood cells have been retrieved. To avoid dehydration, this donation returns the body fluids and more saline to the body. However, you’ll need some rest because you’ve lost a lot of RBCs.

After a power blood donation, the donor must wait 112 days before attempting to donate blood.

Recovery time

A person provides their full blood during a typical donation. It contains red cells, white cells, platelets, and plasma.

The majority of people take a 15-minute break after donating whole blood. Trustworthy. There may be water, juice, or snacks available from an attendant to help alleviate any weariness or dizziness that may occur.

Within a few hours, most people are able to return to their normal routines.

A staggering 2 million red blood cells are produced by the human body every second. Even so, the pint of blood that is extracted during a donation may not be replaced for several weeks. In the meantime, few people are affected by the shortage of blood supply.

There must be at least eight weeks between each donation in order for the donor’s body to recuperate.

Measures To Take After Double Red Cell Donation

A double red cell donation takes how long for the recipient to recover? A full recovery takes about 60 days.

However, if you want your RBCs to recover quickly, you’ll need to eat a specific diet. You lose about 200mg of iron from your body for every two double red cell donations. The majority of people return to their daily routines within a few hours of donating their time.

It’s important to know what to do after donating blood and how to recover from a double red cell donation. The recovery process following blood donation might be sped up by consuming certain foods. After a double red cell donation, there are a few activities you should avoid.

Tip#1. Fatigue and dizziness after donation

Many people experience fatigue and dizziness after making an RBC donation. It is caused by a decrease in the number of red blood cells in the body, which results in a lack of oxygen. Rest and fluid consumption should be increased as soon as symptoms improve. Supplements can also be taken.

Tip#2. Recovery from food sources

“What should I eat after donating blood?” is a reasonable question. The blood iron levels can be raised by consuming foods rich in iron. Red meat, shellfish, beans, dark green leafy vegetables like spinach and peas, iron-rich cereals, pasta, and bread are some of the foods high in iron that you should take in your diet.

Vitamin C aids iron absorption from the gut, therefore it’s important to raise your consumption of foods high in it. Citrus fruits, such as oranges and strawberries, and vegetables, such as broccoli, potatoes, and Brussels sprouts, all contain significant amounts of the antioxidant vitamin C.

Vitamin B12 is also required for the production of red blood cells. Vitamin B can be found in dairy products such as yoghurt, milk, and cheese, among other things. Vitamin C is found in a variety of foods, including leafy greens, bananas, oranges, and potatoes.

Also available as supplements are ferrous sulfate, vitamin C, and vitamin B 12. This includes smoking and drinking alcohol the following day.

Tip#3. Refrain from exercising

After a double red cell donation, the amount of oxygen in your body decreases. Because of this, it’s important to avoid doing anything too strenuous just after giving red blood cells. Physical labor, cardio workouts, and lifting heavy things are all part of this regimen.

Experts advocate taking a day or two off from strenuous physical activity. You should gradually reintroduce exercise and sports into your daily schedule. Gradually reintroducing these activities to your body after double red cell donations can help to avoid any unfavorable effects that may be experienced.

What to eat after blood donation

Donating blood depletes the body of essential nutrients. A person’s body can recover more quickly if they consume particular foods and beverages.


A person’s body can lose 200–250 milligrams of iron with each blood donation.

Blood iron levels can be replenished by consuming meals high in iron. Foods high in iron include, but are not limited to:

  • beef that has been marinated in red wine
  • greens such as spinach
  • broccoli
  • cereals enriched with vitamins and minerals

Citrus fruits, bell peppers and tomatoes are strong sources of vitamin C that can assist the body absorb iron.

An iron supplement may be beneficial for someone who frequently donates blood.

B vitamins

B vitamins, such as B-2, B-6, and B-9, aid in the production of new red blood cells. B vitamins can be found in a variety of foods, including:

  • a variety of leafy greens
  • Dairy products
  • liver
  • potatoes
  • bananas
  • breakfast cereals that are enriched
  • fruit-flavored soda water

If vegetarians or vegans find it difficult to receive enough B vitamins from their diet, they may benefit from taking a B vitamin supplement.


Donating blood flushes out the body of fluids. People can aid in the recovery process by drinking water, broth, or herbal tea.

During the first 24 hours after donating blood, the American Red Cross recommends that donors consume an additional four glasses of liquid.

What to avoid after blood donation

A person’s everyday routine is not disrupted by donating blood. A person’s immediate ability to function may be restricted as a result of a stroke.

Because fewer red blood cells are present, the body is able to utilize its oxygen supply more efficiently. A person should avoid intense activity immediately following a donation, as a result. For example:

  • physical exertion
  • a lot of effort
  • a good aerobic workout

After donating blood, it’s generally a good idea to refrain from strenuous physical activity for the rest of the day.

Gradually reintroducing exercise and heavy lifting is possible going forward. Slowly resuming these activities can help prevent any negative effects from the blood loss.

For the first 24 hours following a donation, a person should abstain from alcohol consumption.

Dizziness or lightheadedness

After donating blood, some people feel dizzy or lightheaded. This is because the lower volume of blood in the body leads to a temporary reduction in blood pressure.

Start gently and avoid any actions that could be risky owing to dizziness or a feeling of being out of place.


A bandage will be applied to the site where the needle was put once a blood donation is completed. They can also gently push on the wound to aid in healing and blood clotting.

Rest may be necessary if the blood does not clot quickly. Make every effort to avoid using the arm while the bandage is on to help prevent bleeding.

You should raise your arm over your head for about five minutes if there is bleeding from the wound site. Trusted Source until the bleeding stops.

Bruising and soreness

You should elevate your arm over your head for around five minutes if you see any bleeding from the wound site. As long as the bleeding doesn’t cease.

If the bruising is bothering you, try applying cold compresses to relieve the pain. Acetaminophen, for example, is an over-the-counter pain reliever (Tylenol).

Aspirin should be avoided by platelet donors for two days before to the donation.


After donating blood, some people feel more fatigued than others, but this is quite normal.

Those who are exhausted after giving blood should take a nap.

Hydration and a boost in vitamin and mineral levels may help alleviate tiredness.

When to see a doctor

If a person observes any side effects from donating blood, they are usually mild.

Those who have long-term or severe side effects should seek medical attention. Among them:

Recovering from a workout can be done in a variety of ways, including:

  • getting enough fluids into your system
  • Iron and vitamins C and B are found in meals that are rich in iron.
  • At least one day off from intensive activity, such as cardiac exercise.

Severe side effects from blood donation are rare. A doctor or the donation center should be contacted by anyone who experiences chronic or severe health difficulties as a result of donating blood.

Why should you do it?

In the event that you haven’t heard, there is a constant requirement for blood. Hemoglobin is a component of red and platelet blood cells, as well as plasma and white blood cells, all of which are present in whole blood donations. Blood transfusions require red blood cells, which are the most commonly used blood component. It is possible to give two red cells in one appointment with Power Red, if you meet certain criteria. It’s just as safe as whole blood donation.

How is it different?

An automated technique is used to draw blood from one arm during your Power Red. Using the same arm, the machine separates and collects two units of red cells, and then returns the remaining blood components, along with some saline, to you in the same manner.

Make your blood donation go further by saving time: The Power Red program may be a good fit if you have a lot on your plate and are a qualified type O, A negative, or B negative blood donor. Using each treatment allows you to provide more of the substance that is most desired by your patients Power Red (gift of double red cells) takes around 30 minutes longer than a whole blood donation, and you can donate about every four months.

After donating blood, you may feel more hydrated since all of your platelets and plasma are returned to you, along with some saline.

Am I Eligible to Donate?

Donating Power Red necessitates that you meet additional requirements for whole blood donors, such as having a hemoglobin level over a certain threshold and being at least 16 years old. Each has a different gender-specific threshold.
