All of the following are common causes of Iron deficiency anemia, EXCEPT?

Chronic blood loss

Liver problems

Decreased folic acid absorption in the gut

Low dietary intake of Iron

Answer and Explanation

The Correct Answer is C

A.   Chronic blood loss is one of the most common causes of iron deficiency anemia. Conditions such as gastrointestinal bleeding (e.g., from ulcers, polyps, or cancer), heavy menstrual periods, or chronic blood donation can lead to a gradual loss of iron, resulting in anemia.
B.   While liver problems can lead to various blood disorders, they are not a direct cause of iron deficiency anemia. Liver disease can affect iron metabolism and storage but does not typically cause iron deficiency unless accompanied by chronic blood loss or malnutrition.
C.   Decreased folic acid absorption leads to folate deficiency anemia, not iron deficiency anemia. While folate is important for red blood cell production, it does not directly influence iron levels. This option is not a common cause of iron deficiency anemia.
D.   Low dietary intake of iron is a well-known cause of iron deficiency anemia. Diets lacking in iron-rich foods (such as red meat, beans, and fortified cereals) can lead to insufficient iron stores and subsequent anemia.

Correct Answer is ["A","C","D","E"]

Explanation

A. This term refers to the passage of fresh blood through the anus, usually indicating lower GI bleeding (such as from the colon or rectum). It is a common and significant sign of GI bleeding.
B. Hypertension (high blood pressure) is generally not a sign of GI bleeding. In fact, GI bleeding typically leads to hypotension (low blood pressure) due to volume loss, making this choice incorrect.
C. Tarry stool (melena) indicates the presence of digested blood in the stool, typically resulting from upper GI bleeding. It appears black and sticky and is a common sign of GI bleeding.
D. This refers to vomiting that looks like coffee grounds, which indicates that blood has been present in the stomach and has undergone digestion. This is a classic sign of upper GI bleeding and is a significant symptom.
E. Hematemesis is the vomiting of blood, which can be bright red or resemble coffee grounds, depending on the source and severity of the bleeding. It is a common and serious sign of GI bleeding, particularly from the upper GI tract.

A. High serum Iron and Low MCV B. High serum Iron and Mean Corpuscular Volume (MCV) C. High Total Iron Binding Capacity: Low serum Iron and MCV D. None of the above

Correct Answer is C

Explanation

A. In iron deficiency anemia, serum iron levels are typically low due to a deficiency in iron. Additionally, the Mean Corpuscular Volume (MCV) is often low because the red blood cells produced are smaller than normal (microcytic).
B. Similar to option A, serum iron levels in iron deficiency anemia would be low, not high. The MCV may be low or normal, but it would not be high due to the production of microcytic red blood cells.
C. In iron deficiency anemia, TIBC is usually high because the body is trying to maximize iron transport in response to low iron levels. Serum iron is low, and the MCV is low due to the production of smaller red blood cells.
D. This option is incorrect because option C accurately describes the expected lab results in iron deficiency anemia.
