Does Donating Plasma Burn Calories?

Donating plasma does not burn a significant number of calories. While donating plasma requires some physical activity, producing an effective caloric burn is not strenuous enough.

Donating plasma involves sitting comfortably in a chair while a small amount of blood is drawn from your arm, processed to collect the plasma, and then returned to your body with saline solution. The entire process usually takes around 60-90 minutes.

During this time, you may experience a slight increase in heart rate and metabolism due to the body’s natural response to the donation process. The energy expenditure is minimal and does not lead to a noticeable calorie burn.

If you want to burn calories or engage in physical activity, donating plasma is ineffective. For calorie burning and overall health benefits, engaging in regular exercise and maintaining a balanced diet is essential.

How Plasma Donation Works?

A needle is inserted into the donor’s arm to draw blood during plasma donation. The blood is then passed through a machine separating the plasma from the other components. The separated plasma is collected in a bag, and the other parts are returned to the donor’s body.

Plasma is a clear, yellowish liquid that makes up about 55% of the blood’s volume. It contains proteins and other essential components that help blood clotting, immunity, and fluid balance. Plasma donation does not burn calories directly but can affect the body’s energy expenditure differently.

Plasma donation is a process by which individuals voluntarily give a portion of their blood plasma to help others in need. Plasma is the liquid component of blood that carries various proteins, nutrients, hormones, and antibodies essential for bodily functions and clotting factors.

Here’s an overview of how plasma donation typically works:

Eligibility and Pre-screening:
Before donating plasma, potential donors must meet specific eligibility criteria set by the donation center or blood bank. These criteria may include age restrictions, weight requirements, overall health, and the absence of certain medical conditions or medications.

Registration and Health History:
Once at the donation center, the donor must register and provide their identification information. They will also be asked to complete a health history questionnaire, where they must truthfully answer questions about their medical history, recent travel, and other relevant factors.

Physical Examination and Vital Signs:
A healthcare professional will conduct a brief physical examination, which typically includes checking the donor’s blood pressure, pulse, and temperature, to ensure they are in good health for donation.

The donation process begins with venipuncture, where a sterile needle is inserted into a vein in the donor’s arm. The blood is collected through this needle and flows into a specialized collection bag or machine.

Separation of Plasma:
In most cases, an automated plasmapheresis machine separates the plasma from the other blood components, such as red blood cells and platelets. The device collects the plasma while returning the remaining blood components to the donor.

Plasma Collection and Donor Monitoring:
The plasmapheresis process typically takes 60-90 minutes, during which the plasma is collected. Throughout the donation, trained staff carefully monitors the donor to ensure their safety and well-being.

Final Steps:
Once the plasma donation is complete, the needle is removed, and the donor is encouraged to rest for a few minutes. Donors are usually provided with snacks and beverages to help replenish fluids and prevent lightheadedness.

Post-Donation Care:
After donating plasma, donors are advised to stay hydrated and avoid heavy lifting or strenuous activities for a few hours. Donating plasma does not significantly impact the body’s overall blood volume, as the body quickly replenishes the donated plasma within 24-48 hours.

Energy Expenditure During Plasma Donation

Donating plasma involves sitting in a chair for about 45 minutes to an hour. During this time, the body burns calories to maintain essential functions, such as breathing, heart rate, and temperature regulation. The amount of calories burned during plasma donation is relatively low, about 150-200 calories on average.

Several factors can affect the number of calories burned during plasma donation, such as the donor’s weight, age, and gender. Generally, the more body mass a person has, the more calories they burn during physical activity, including plasma donation.

The After-Effects of Plasma Donation

After donating plasma, some individuals may experience mild after-effects. It’s important to note that these effects are generally temporary and vary from person to person. Here are some common after-effects of plasma donation:

Fatigue: Feeling tired or fatigued is one of the most common after-effects of plasma donation. Donating plasma can temporarily lower energy levels, especially if the donor is not adequately hydrated or well-rested before the offering.

Lightheadedness or Dizziness: Some donors may experience lightheadedness or dizziness after donating plasma. This can occur due to a temporary drop in blood pressure or a reduction in blood volume. Sitting or lying down and resting after the donation is essential to help alleviate these symptoms.

Bruising or Soreness: After plasma donation, bruising or soreness around the needle insertion site is possible. This is a minor side effect and should resolve within a few days. Applying a cold compress to the area can help reduce swelling and discomfort.

Nausea: A small number of donors may experience mild nausea or an upset stomach after donating plasma. This is usually transient and can be managed by resting and staying hydrated.

Tingling or Numbness: Donors may feel tingling or numbness in their hands or arms after donation. This is typically due to the anticoagulant used during assistance, which prevents blood from clotting. The sensation usually subsides once the anticoagulant wears off.

Hydration and Appetite: Plasma donation can temporarily dehydrate the body. Donors must drink plenty of fluids and stay well-hydrated before and after the gift. Donors may also experience increased appetite after donation, which is the body’s way of replenishing lost nutrients.


How long does it take to recover from plasma donation?

The body replaces the lost plasma within 24-48 hours, but it can take several weeks for the other blood components to replenish fully.

Can donating plasma make you lose weight?

Donating plasma may cause temporary weight loss due to the loss of fluids, but it is not a reliable method for long-term weight loss.

Can plasma donation affect blood sugar levels?

Plasma donation can cause a temporary drop in blood sugar levels, but it is typically not significant enough to cause any health problems.

Is plasma donation safe?

Yes, plasma donation is safe for most healthy adults. The equipment used during the process is sterile, and the staff follows strict safety protocols to ensure the donor’s safety.

How often can you donate plasma?

Most plasma donation centers allow donors to donate up to twice a week, with at least 48 hours between donations. Following the center’s guidelines and not exceeding the recommended donation frequency is essential.


In conclusion, donating plasma is a selfless act that can help save lives. It is not an effective way to burn calories. While the body does burn some calories during plasma donation and recovery, the amount is relatively low. For those looking to burn calories, focusing on proven methods such as exercise, diet, and lifestyle changes is recommended.
