5. Infection and Serious Illness
In some cases, anemia can occur after an infection. That’s because infections can spread into the bone marrow, affecting the amount of blood produced by the body. Blood cells are produced in the bone marrow. In fact, 95% of the blood cells are made by it.
If an infection gets to the bone marrow, blood reproduction may happen at a slower rate or even not happen at all. As a result, your body may not be able to replace blood fast enough, and sometimes the blood loss isn’t replaced at all.
Debilitating medical conditions, such as rheumatoid arthritis, can have a detrimental effect on bone marrow. Another way to become anemic is through chemotherapy. It is known to attack cancer cells, but it also tends to harm other cells in the body, such as red blood cells.
