Answer

Under normal conditions, less than 10% of the total albumin is lost through the intestine. This fact has been confirmed by comparing albumin labeled with chromium-51, which helps measure intestinal losses, to albumin labeled with iodine-125, which helps measure overall degradation. In cases of protein-losing enteropathy related to bacterial overgrowth, hypoalbuminemia is exacerbated by peripheral factors that inhibit albumin synthesis by mechanisms similar to those observed with burns, trauma, infection, and carcinoma.
