Sickle Cell Anemia Pathophysiology: Sickle cell anemia is a disease passed down through families in which red blood cells form an abnormal crescent shape. The “sickling” occurs because of a mutation in the hemoglobin gene. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain‚ serious infections‚ and organ damage. Life expectancy in people who have this disease is shortened. Anemia is a condition in

crescent‚ holly wreath‚ and other forms. This process is known as sickling. What is Sickle Cell Anemia? It is a blood disorder that affects hemoglobin‚ red blood cells with normal hemoglobin move easily through the bloodstream‚ delivering oxygen to all of the cells of the body. Normal red blood cells are shaped like doughnuts with the centers partially scooped out and are soft and flexible. Sickle cell anemia occurs when an abnormal form of hemoglobin is produced. HbS molecules tend to clump together

sickle cell anemia affects about 72‚000 Americans in the United States. Sickle cell anemia is an inherited disease in which the body is unable to produce normal hemoglobin‚ an iron-containing protein. Abnormal hemoglobin can morph cells that can become lodged in narrow blood vessels‚ blocking oxygen from reaching organs and tissues. The effects of sickle cell anemia are bouts of extreme pain‚ infectious‚ fever‚ jaundice‚ stroke‚ slow growth‚ organ‚ and failure. Sickle cell anemia hurts many
Free Red blood cell Sickle-cell disease Hemoglobin
Sickle Cell Anemia is an inherited disorder that affects the building of hemoglobin in the body. Hemoglobin is a protein in red blood cells that moves oxygen through the body. People are born with sickle cell anemia when they inherit two abnormal genes from both parents (one from each). People with sickle cell disease has a hemoglobin called hemoglobin S. Normally cells move through the body easily but for people who have sickle cell anemia‚ their cells tend to block blood vessels. Normal red blood

Sickle cell anemia (SCA) also known as sickle-cell disease (SDA) is the most common genetic blood disorder that most people know far to little about. It is blood disease identified by abnormal looking red blood cells (Primary Health Care 2012). Normal blood cells tend to be soft and round and travel to through the body smoothly as for sickle cells‚ on the other hand‚ look like a hard falcate moon shape (Primary Health Care 2012). These abnormal red blood cells result in a difficult blood flow

Vitamin C 1. Vitamin C is a required vitamin for the synthesis of collagen‚ norepinephrine‚ and carnitine. Collagen is a crucial component in the structure of blood vessels‚ tendons‚ ligaments‚ and bone. Norepinephrine is a neurotransmitter which is critical for proper brain function. Carnitine is a small molecule that is essential for transporting fat into the mitochondria of cells to be later converted into energy. Vitamin C is also used as a highly effective antioxidant to help protect key

Sickle cell anemia Sickle cell anemia is a disease found right here in America‚ but in low levels compare to most of the world. The rate for disease is around five times greater in certain places in Africa. Sickle-Cell Anemia is often referred to as the “Negro-Inherited” disease‚ but that is incorrect. Although African Americans have a high occurrence of Sickle-Cell Anemia (1 in 400 African Americans)‚ many other nationalities suffer from the disease. Sickle-Cell Anemia affects 8 out of 100‚000

Anemia (ah-NEE-mee-ah) is a medical condition that occurs when a person does not have enough red blood cells. Red blood cells are important because they contain hemoglobin‚ a protein that carries oxygen from the lungs to the body’s muscles and organs. The body requires oxygen for energy. Therefore‚ when you are anemic‚ you may feel tired mentally and physically. Symptoms of anemia include:7‚8‚9‚10 · Fatigue · Weakness · Shortness of breath · Dizziness or fainting · Pale skin‚ including decreased

Other diseases that target red blood cells include sickle-cell anemia and thalassemia . J.B.S. Haldane (one of the first people to understand evolutionary pressure and its effects) suggested that sickle-cell anemia and thalassemia‚ helped its host better resist malaria (Dr.Moalem 89).
