How can multiple myeloma affect feeling faint during menstruation, and what can be done?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Feeling faint during your period is often caused by hormonal shifts, blood loss, and drops in blood pressure that reduce circulation to the brain. While available references don't directly link multiple myeloma to menstrual fainting, dizziness during menstruation can stem from anemia, dehydration, or underlying conditions worth investigating.

Because faintness has many possible causes—some benign, others requiring medical attention—it's smart to get personalized insight before assuming the worst or dismissing it entirely. A free, instant, online symptom check can help you understand what may be driving your symptoms and guide your next steps, whether that's self-care, lifestyle changes, or seeing a doctor. It takes just a few minutes and could bring real clarity.

Explanation

Feeling faint or dizzy during menstruation can be influenced by various factors, including hormonal changes and blood flow dynamics. Reference 1 discusses dizziness related to the menstrual cycle, indicating that vertigo may be more common in the premenstrual period. However, it does not specifically address multiple myeloma.

Multiple myeloma is a type of cancer that affects plasma cells in the blood, which can lead to anemia. Anemia may cause symptoms like dizziness or feeling faint, especially during menstruation when blood loss occurs. However, the provided references do not discuss the specific impact of multiple myeloma on these symptoms.

If you experience dizziness or fainting during your period, it is important to consult with a healthcare provider. To better understand what might be causing your symptoms, you can take our free AI symptom checker before your appointment. They can evaluate your symptoms in the context of your overall health and any conditions like multiple myeloma. A healthcare provider can offer guidance on managing symptoms and provide appropriate treatment or lifestyle recommendations.
