Are you wondering how lupus affects red blood cell (RBC) counts? It's a really common concern — around 50% of people with lupus experience anemia (low RBCs) at some point.
When RBC levels drop, your body has to work harder to deliver oxygen, which can leave you feeling:
- Tired or weak
- Dizzy or short of breath
- Like your heart is beating irregularly
- Cold in your hands or feet
- Pale or yellowish in skin tone Lupus can cause low RBCs in a few different ways:
- Inflammation — Long-term immune system activity can interfere with red blood cell production (this is the most common cause)
- Immune attacks — The immune system may mistakenly target and destroy RBCs
- Kidney involvement — Lupus-related kidney issues can affect RBC production
- Medications — Some lupus treatments like immunosuppressives or NSAIDs can contribute to lower RBC counts
A simple blood test called a Complete Blood Count (CBC) is used to check your RBC levels and hemoglobin. If anemia is found, treatment usually involves adjusting your care plan while keeping lupus under control.
It's worth flagging any symptoms to your doctor so they can monitor things closely. As one MyLupusTeam member put it, "You definitely need blood tests to keep an eye on what's going on with lupus symptoms to make sure it's not affecting other organs."
