血色素正常 为啥就“血虚”了

Core Viewpoint - The article discusses the distinction between "blood deficiency" in Traditional Chinese Medicine (TCM) and "anemia" in Western medicine, highlighting that they are not the same condition despite some overlapping symptoms [2][4]. Group 1: Definitions and Concepts - Western medicine defines anemia as a condition characterized by a deficiency in circulating red blood cells, leading to low hemoglobin levels below specific thresholds [4]. - In contrast, TCM's concept of "blood deficiency" refers to a state where blood is insufficient to nourish organs and meridians, diagnosed through clinical symptoms rather than laboratory tests [4]. Group 2: Symptoms and Diagnosis - Both anemia and blood deficiency can present similar symptoms such as pale complexion, dizziness, and fatigue, but TCM emphasizes a broader understanding of overall nourishment and functional status [4]. - The diagnosis of blood deficiency in TCM relies on clinical observations like pale complexion and weak pulse, rather than solely on blood test results [4]. Group 3: Historical Context - The understanding of "blood" in TCM encompasses both material and functional aspects, with historical roots tracing back to ancient texts like "Nanjing" attributed to the physician Bian Que [3]. - TCM's definition of blood includes its nourishing and moistening roles, which are considered more comprehensive than the Western definition focused on blood as a physical substance [3].
