Question

3 Main physiologic causes for anemia:

a) Lack of vitamin C, D, E
b) Iron deficiency, vitamin B12 deficiency, chronic disease
c) High cholesterol, low blood pressure, obesity
d) Insomnia, stress, anxiety

Answer 1

The three main physiological causes of anemia are iron deficiency, vitamin B12 deficiency, and chronic diseases. Iron deficiency anemia occurs when there is a lack of available iron, while vitamin B12 deficiency anemia involves insufficient vitamin B12 and folate. Chronic diseases such as chronic kidney disease, hypothyroidism, cancer, lupus, and rheumatoid arthritis can also lead to anemia.

Step-by-step explanation:

Anemia: Causes and Deficiencies

Anemia is a disorder characterized by a lack of red blood cells in the blood, leading to a reduced ability to carry oxygen. The main physiological causes of anemia are iron deficiency, vitamin B12 deficiency, and chronic diseases. Iron deficiency anemia occurs when there is a lack of available iron, which is necessary to produce sufficient heme. Vitamin B12 deficiency anemia, on the other hand, involves insufficient vitamin B12 and folate. Chronic diseases such as chronic kidney disease, hypothyroidism, cancer, lupus, and rheumatoid arthritis can also lead to anemia.
