Essay: Blood Disease-Sickle cell anemia
This disease is inherited and it has been seen to affect any gender across all age groups. It derives it name from the fact that hemoglobin type A, which is a carrier off oxygen, usually turns in to a sickle shape when infected. The normal lifespan of hemoglobin is 120 days plus or minus 10 days, it is round in shape and spongy- hemoglobin type A. When infected, hemoglobin’s life spans lowered to about 20 days and its shape turns into a sickle shape. This does not allow hemoglobin sickle (hemoglobin S) to flow through the veins and therefore clogs them.
Complete abstraction of blood flow to the body leads to suffocation and eventual death of body tissues. If the bone marrow does not adapt to this condition of producing extra amounts of red blood cells, this disease can lead to death by affecting the lungs, liver, kidneys, and the central nervous system. Statistics show that for every 400 individual in African Americans, one is affected while in every one million people worldwide, eight persons are affected (Stewart et al, p 4-5)
In America, the disease affects 70,000 to 100,000 with a frequency of one out of every 500 African American births. One out of every 36,000 Hispanics suffer this disease with its trait occurring in 1 out of every 12 African Americans.
Deaths in African-American children reduced by 42% between 1999 and 2002.
