A member asked:

What does high bun 44 mean?

A doctor has provided 1 answer

High BUN: May mean that you have kidney disease, or hemolytic anemia, or gastrointestinal bleeding, or stomach obstruction. Dehydration also can cause the level of blood urea nitrogen to be falsely higher. Thanks for trusting in HealthTap.
