Importance of Spleen for Blood Donations

[Broadsword2004]

My uncle is sixty-one years-old, and he donates blood every two months. The thing is, he has no spleen. He seems to be acting a bit different lately, like a lot more tired and sleeping constantly. I think that is probably because he is giving blood often and he works hard and well he's in his sixties now, but can not having a spleen be having any kind of adverse affect on him? Or is he likely just giving too often for his age and work schedule?

Lack of a spleen makes him more susceptible to certain types of infections, but is not responsible for his fatigue.

There are other issues which need to be explored here. Take him to his doctor.
