yanalaym [24]

Answer:

Answer is hemolytic anemia.

Explanation:

Hemolysis is the destruction of red-blood cells, while anemia when the amount of the red blood cells in the body is lower than the expected or normal.

Therefore, hemolytic anemia can be defined as a disorder or situation where the rate at which the red blood cells are destroyed is faster compared to the rate at which they are made or produced.

This can be caused by bone marrow failure or infections, and inherited blood disorder like sickle cell disease.

The hemolytic anemia is a serious disorder that can damage the heart and other organ of the body, this is because of oxygen starvation, since the red blood cells responsible for carrying oxygen around the body have been affected.

Eating some food items like beans, green vegetables, red meat and legumes can increase red blood cell count.
