can donating plasma affect your menstrual cycle

Donating plasma is a great way to help others and make some extra money. But can it affect your menstrual cycle? While the answer is not definitive, donating plasma may have some effects on your menstrual cycle.

What is Plasma?

Plasma is the liquid component of your blood. It is mainly composed of water, salts, and proteins. It carries red and white blood cells, platelets, and antibodies throughout your body. Plasma is used in a variety of medical treatments, including treating burn victims, trauma patients, and those with bleeding disorders. It’s also used to make clotting factors, and to create products that help treat diseases such as hemophilia and hepatitis.

Can Donating Plasma Affect Your Menstrual Cycle?

Potentially. When you donate plasma, your body needs to replace the lost plasma and other components of your blood. This involves a process known as hemodilution. During hemodilution, your body needs to draw on its resources in order to replace the lost plasma, which can cause a decrease in your red blood cell and hemoglobin levels. A decrease in these levels can affect your menstrual cycle.

Studies have shown that women who donate plasma regularly may experience irregular menstrual cycles. In addition, women who donate more than once a week may be at an increased risk of experiencing a disruption in their menstrual cycle.

What Are the Other Potential Side Effects of Donating Plasma?

In addition to a potential disruption in your menstrual cycle, there are other potential side effects of donating plasma. These include fatigue, lightheadedness, and nausea. If you experience any of these symptoms after donating plasma, you should stop donating and see a doctor.


Q: Is donating plasma safe?

A: Yes, donating plasma is generally safe. It is a sterile and regulated process, and the equipment used is regularly sanitized. However, as with any medical procedure, there are potential risks, so make sure to speak with your doctor before donating.

Q: How often can I donate plasma?

A: Depending on your health and the rules of the plasma donation center, you may be able to donate plasma up to twice per week, with at least 48 hours between donations.

Q: How much can I make from donating plasma?

A: The amount you can make from donating plasma varies, but you can usually expect to make anywhere from $20 to $50 per donation.


Donating plasma can be a great way to help others and make some extra money. However, it’s important to understand that it may have an effect on your menstrual cycle. If you’re considering donating plasma, make sure to speak with your doctor to discuss any potential risks.
