Fatigue

Fatigue is a feeling of being very tired or weak. It is different from normal tiredness. It often does not go away with rest. It can affect your body, your mind, or both. 

Why does fatigue happen after CAR-T?

Many people with lymphoma feel fatigued after receiving CAR T-cell therapy. This is common and can happen for several reasons:

• The cancer itself. Lymphoma can affect the immune system, which can lead to tiredness.
• Inflammation. CAR-T can cause inflammation in the body, which can make you feel fatigued.
• Low red blood cell count (anemia). CAR-T may lower the number of red blood cells. These cells carry oxygen, and when there are fewer of them, you may feel weak or short of breath.
• Stress from treatment. Living with lymphoma and going through CAR-T can be physically and emotionally stressful, which adds to fatigue.
• Lymphodepletion. The short course of chemotherapy given before CAR-T can contribute to fatigue.
