I'm curious about the effects of a blood transfusion. Specifically, could receiving one actually cause a spike in blood sugar levels, even if the transfused blood has a normal glucose level? Im really concerned about how safe it is.

Yes, blood transfusion can potentially increase blood sugar levels, especially in patients who receive blood with high levels of glucose. This can happen if the donor had high blood sugar levels at the time of donation. To manage this, it is important to monitor blood sugar levels closely during and after a blood transfusion. If needed, insulin therapy may be initiated to control the blood sugar levels.
