Is my fatigue due to low hemoglobin levels?

I am in the middle of chemotherapy treatment and my hemoglobin levels are dropping. Is that the reason I am so, so tired?

Generally that plays a big roll in feeling tired during chemotherapy

Chemotherapy itself causes fatigue. You can ask your physician if your hemoglobin is low enough to cause fafigue

Probably and your doctor should be able to give you specific results and info.

Certainly it is at least partially responsible, but chemotherapy itself could be a contributing factor.
