The symptoms of Sickle Cell Anemia are as follows: Long/Short bouts of pain, damage to vital organs, and in some extreme cases death in children and young adults.
Sickle Cell Anemia affects the production of a protein in red blood cells called hemoglobin. Hemoglobin is what carries oxygen to all the parts of the body, when the oxygen is affected it causes the red blood cell to crook like a banana or sickle so that they may not fit through blood vessels and clog them. If they do happen to fit through the blood vessels then they end up in the liver and spleen where they are destroyed, which in turn causes a lack of red blood cells, that is where the Anemia comes from.
There are three types of SCA, they are SS disease, Sickle "C" disease, and Sickle beta thalassemia, the latter is very rare compared to the first two.
