The Disease Caused Due to Deficiency of Iron is Known as
Option 3 ( Anemia ) is the right answer.
Iron-deficiency anemia, also spelled iron-deficiency Anaemia, is defined as a decrease in the amount of red blood cells (RBCs) or hemoglobin in the blood due to not enough iron. When anemia comes on slowly the symptoms are often vague and may include: feeling tired, weakness, shortness of breath or a poor ability to exercise. Anemia that comes on quickly often has greater symptoms which may include: confusion, feeling like one is going to pass out, and increased thirst.
It is caused by insufficient dietary intake and absorption of iron, or iron loss from bleeding. Bleeding can be from a range of sources such as the intestinal, uterine or urinary tract.
