What is the fundamental physiologic manifestation of anemia? The fundamental physiologic manifestation of anemia is a reduced oxygen-carrying capacity of the blood, resulting in tissue hypoxia.
What is the physiological classification of anemia?
Anemia can be classified as microcytic, normocytic or macrocytic, depending on MCV. As stated above, it can be hypo-regenerative or regenerative, which depends on the number of reticulocytes.
What are the three major laboratory manifestations of anemia?
The laboratory evaluation of anemia begins with a complete blood count and reticulocyte count. The anemia is then categorized as microcytic, macrocytic or normocytic, with or without reticulocytosis.
What is the physiological basis of pernicious anemia?
Pernicious anemia is a relatively rare autoimmune disorder that causes diminishment in dietary vitamin B12 (cobalamin) absorption, resulting in B12 deficiency and subsequent megaloblastic anemia. It affects people of all ages worldwide, particularly those over 60.

What is the most significant physiological effect of anemia?
The most serious complications of severe anemia arise from tissue hypoxia. Shock, hypotension, or coronary and pulmonary insufficiency can occur. This is more common in older individuals with underlying pulmonary and cardiovascular disease.
What is the physiological cause of iron deficiency anemia?
The depletion of iron stores may result from blood loss, decreased intake, impaired absorption, or increased demand. Iron-deficiency anemia could arise from occult gastrointestinal bleeding. Adults older than 50 years of age with iron-deficiency anemia and gastrointestinal bleeding need to be evaluated for malignancy.
What is the cardinal symptom of anemia?
In particular, fatigue is considered the cardinal symptom of anemia. The pathogenesis of anemia-related fatigue remains unclear, but some suggest that abnormalities in energy metabolism play a role in inducing fatigue.
What is the first indicator of iron-deficiency anemia the earliest change?
Symptoms of iron-deficiency anemia are related to decreased oxygen delivery to the entire body and may include: Being pale or having yellow “sallow” skin. Unexplained fatigue or lack of energy. Shortness of breath or chest pain, especially with activity.
What is the clinical observation of anemia?
Common symptoms of anemia include fatigue, irritability, headaches and difficulty concentrating. Your doctor may detect a heart murmur or a sudden drop in blood pressure when you stand. A blood test will provide counts of your white blood cells, red blood cells and platelets.
What is the clinical significance of anemia?
A change in red blood cells affects the release of EPO. For example, people with anemia have too few red blood cells, so more EPO is produced. Increased EPO levels may be due to secondary polycythemia, an overproduction of red blood cells that occurs in response to an event such as low blood-oxygen levels.
What is the clinical presentation of anemia of chronic disease?
Affected individuals may develop a variety of symptoms such as fatigue, paleness of the skin (pallor), lightheadedness, shortness of breath, a fast heartbeat, irritability, chest pain and additional findings. These symptoms may occur in any individual who has a comparable degree of anemia.
