Sickle cell disease (SCD) is an inherited group of blood disorder which is genetic in nature. It is usually transferred from parents to the child during birth i.e. both the parents can be carries of SCD. Healthy RBCs are round in shape, which moves through small blood vessels and carries oxygen to all parts of the body. In someone who has SCD, the RBC becomes sticky and hard and start to look like C- shaped similar to that of a farm tool ‘sickle’. The sickle cells die early, which causes a constant shortage of RBC, which leads to low oxygen carriers in the body. Also, when sickle cells travels they tend to get stuck in small blood vessels and restrict the blood flow. This can cause pain in the joints, chest and other serious problems such as stroke, acute chest syndrome and infections.

Symptoms of Sickle Cell Disease include:
