Plasma donation involves collecting the liquid portion of blood, plasma, while returning red blood cells to the donor. Many wonder about resuming physical activities, like running, afterward. Understanding the body’s response and necessary precautions is important for a safe recovery.
The Body’s Response to Plasma Donation
Donating plasma involves removing a significant amount of fluid from the body. Plasma contains water, proteins, salts, and other essential nutrients. This temporary fluid loss can lead to a brief reduction in blood volume and a slight drop in blood pressure.
A machine separates the plasma from red blood cells, which are returned to the donor. The body begins to replenish lost plasma fluid quickly, within 24 to 48 hours. However, complete regeneration of proteins might take a few days. This temporary depletion contributes to feelings of fatigue or lightheadedness immediately following the donation.
Safe Exercise After Donating
After plasma donation, allow adequate recovery time before strenuous physical activity. Strenuous exercise, including running, should be avoided for at least 24 hours. This allows the body to replenish fluids and stabilize blood pressure, reducing dizziness or fainting risk.
Light exercises, such as walking or gentle stretching, may be considered after 24 hours if one feels well. For a full return to moderate to intense exercise, including running, a 48-hour waiting period is recommended. Also, avoid heavy lifting with the donation arm for at least 24 hours to prevent bruising or bleeding at the needle site. Listen to your body and ease back into exercise gradually.
What to Do If You Feel Unwell
Minor side effects after plasma donation are common and usually resolve quickly. These include lightheadedness, dizziness, or fatigue from temporary fluid and nutrient loss. Mild bruising at the donation site is also possible. If these symptoms occur, resting, drinking plenty of fluids, and consuming a light snack can help alleviate them.
More concerning symptoms warrant medical attention. Consult a healthcare provider if dizziness persists or worsens, or if you experience unusual fatigue, persistent arm pain, tingling, or numbness. Signs of infection at the donation site, such as increasing pain, swelling, redness, warmth, or pus, require prompt medical evaluation. Rare reactions like tingling around the mouth, chills, or difficulty breathing, possibly related to the anticoagulant, require immediate reporting to donation center staff or seeking emergency care.
