Normally, red blood cells live for about 120 days before new ones replace them.People with sickle cell conditions make a different form of hemoglobin A called hemoglobin S (S stands for sickle). Red blood cells containing mostly hemoglobin S do not live as long as normal red blood cells (normally about 16 days). They also become stiff, distorted in shape and have difficulty passing through the body's small blood vessels. When sickle-shaped cells block small blood vessels, less blood can get to that part of the body. Tissue that does not receive a normal blood flow eventually becomes damaged.
Red blood cells usually live for 120 days before they need to be replaced by new ones. However, sickle cells die off after ten to twenty days. Another symptom of sickle cell anemia is episodes of pain. Episodes of pain are one of the major symptoms of sickle cell anemia. The pain develops because sickle-shaped red blood cells block the flow through tiny blood vessels to your abdomen, joints, and chest.
The rapid breakdown of red blood cells may also cause yellowing of the eyes and skin, which are signs of jaundice. Jaundice is also a disorder doctors pay close attention to after a baby is born. Then you have the painful episodes that can occur when sickled red blood cells, which are stiff and inflexible, get stuck in small blood vessels. These episodes deprive tissues and organs of oxygen-rich blood and can lead to organ damage, especially in the lungs, kidneys, spleen, and brain. A particularly serious complication of sickle cell disease is high blood pressure in the blood vessels that supply the lungs.
Meanwhile, the bone marrow, where red blood cells are made, pitches in by making more cells. It can't keep up with the destruction, though, so the total number of red blood cells drops to a low level and the body becomes anemic. ("Anemic" is the medical word for having a low number of red blood cells.) What is sickle cell anemia? Sickle cell anemia is an inherited disease of red blood cells.

Sickle cell diseases (SCD) are diseases which are caused due to disorder of hemoglobin in hour body. Hemoglobin is a protein that transports oxygen through the red blood cells. People with sickle cell diseases have hemoglobin S which shapes the red blood cells in a sickle shape. Sickle cell diseases cause painful vaso-occlusive crises (VOC), stroke, acute chest syndrome, splenic sequestration, chronic pulmonary and renal dysfunction, and a vascular necrosis of the joints. It also causes physical and psychological stress of illness.
Sickle Cell Disease: An Overview Sickle Cell Disease is a genetic disorder in which the body produces sickled shaped red blood cells. In sickle cell disease, or SCD, the hemoglobin in red blood cells groups together. This causes red blood cells to become stiff and C-shaped. These sickled cells prevent blood and oxygen flow in blood vessels, and collect in the blood vessels of the limbs and organs, impeading proper oxygenation of the blood. The most common signs and symptoms are linked to anemia and pain.
In turn, this could cause organ damage to the body. Sickle cells are also fragile and die very easily due to the fact sickle cells have a lifespan of twenty days instead of the normal one hundred and twenty days for normal red blood cells.This causes the body to have a lower blood cell count, hence the name anemia in sickle cell anemia. Hemoglobin SS happens because of a mutation in chromosome 11. Chromosome 11 contains the gene of hemoglobin-Beta. Hemoglobin (HBB) transports oxygen to your body parts like your lungs.
Perspective/Overview Sickle cell anemia is a disease that reforms the patient’s red blood cells, which makes the red blood cells has an abnormal shape like a sickle. Sickled red blood cells can result to severe anemia; decrease causes numerous painful symptoms in patients. A defective protein called hemoglobin is what cause the abnormal shape of the red blood cells in the sickle cell patients. Sickle cell anemia is a genetic disorder that erythrocytes tolerate sickle shape red blood cells. These red blood cells are easy to damage, which leads to hemolytic anemia.
Interactions of tubular and vascular events result in ARF and the leading cause of ARF is ischemia, which is the restricted supply of blood to tissues. This decline of renal blood flow causes cells of the kidney to die. The three phases of acute renal failure are prerenal, intrarenal and postrenal. The most common type of ARF is prerenal acute renal failure and accounts for approximately 55% of all ARF cases. Prerenal ARF is caused by a complication of any condition, medication or disease that causes a rapid decrease of blood flow to the kidneys, which in turn causes a loss of kidney function.
