Birth Disorder & Malnutrition
Birth disorders, also known as congenital disorders [4] like Kostmann syndrome and myelokathexis may lead to leukopenia. Premature babies also suffer a lower number of red blood cells compared to fully developed babies. Babies that are born prematurely have red blood cells that die faster than in full-grown babies.
The human body requires some essentials nutrients and vitamins to develop properly, so certain deficiencies may lead to leukopenia. Vitamin B-12 is essential for enough healthy red blood cells in the body. It supports overall health by stimulating the growth of red blood cells, which transports oxygen throughout the body. Nutrients like folate, copper, and zinc are also needed for the adequate number of red blood cells in the body.
