- Red Blood Cell Disorders. Anemia is one type of red blood cell disorder usually caused by a lack of the mineral iron in your blood. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells carry oxygen from your lungs to the rest of your body.

Sickle Cell Anemia Sickle cell disease occurs from genetic changes that cause abnormalities in hemoglobin molecules: 1  Hemoglobin A (HbA) . 2  HbA is the hemoglobin molecule found in normal red blood cells during childhood and adulthood. 3  People who do not have sickle cell disease generally have this type of hemoglobin in their blood cells.ickle cell disease is an inherited blood disorder in which the body produces abnormally shaped red blood cells. In sickle cell disease, the hemoglobin in red blood cells clumps together. This causes red blood cells to become stiff and C-shaped.

Medical Glossary Conditions that can cause a reduced production of red blood cells include: 1  Iron deficiency anemia. The most common type of anemia, it affects kids and teens of any age who have a diet low in iron or who've lost a lot of RBCs (and the iron they contain) through bleeding. 2  Lead poisoning.

- Red blood cells carry oxygen from your lungs to the rest of your body. Abnormal red blood cell levels may be a sign of anemia, dehydration (too little fluid in the body), bleeding, or another disorder.

Blood: Facts Pediatric Blood Cell Disorders (White Blood Cell Disorders). These disorders affect the white blood cells of children. They occur when the bone marrow produces too many or too few white blood cells. When there are not enough white blood cells, the body cannot fight off infections.

Types of Blood Disorders Blood Disorders Affecting Red Blood Cells. Blood disorders that affect red blood cells include: Anemia: People with anemia have a low number of red blood cells. Mild anemia often causes no symptoms.More severe anemia can cause fatigue, pale skin, and shortness of breath with exertion.lood disorders can affect any of the three main components of blood: 1  Red blood cells, which carry oxygen to the body's tissues. 2  White blood cells, which fight infections. 3  Platelets, which help blood to clot.

- The defect may be in the red blood cell itself (intrinsic factor), or outside the red blood cell (extrinsic factor). Causes of hemolytic anemia include infection, certain medications, autoimmune disorders (such as Lupus), and inherited disorders. There are several different types of anemia. There is no known prevention for hemolytic anemia. These are tests for hemolysis (red blood cell destruction).

- In PV, too many red blood cells are produced, but sometimes it can also result in too many white blood cells or too many platelets (the component of blood that aids in clotting).A considerable amount of research is currently investigating PV and its treatment.Exactly why PV develops is still unclear.olycythemia vera (PV) is a blood disorder in which the body makes too many red blood cells. It's one in a family of diseases called myeloproliferative disorders.

Slideshow: A Visual Guide to Anemia Inherited disorders can affect your body’s production of red blood cells. Thalassemias cause the body to make fewer healthy red blood cells and less hemoglobin -- and may be treated with blood transfusions. Among people with hemolytic anemia, red blood cells are destroyed and cleaned out of the bloodstream too quickly.

Anemia Doctors try to determine if a low red blood cell count is caused by increased blood loss of red blood cells or from decreased production of them in the bone marrow. Knowing whether the number of white blood cells and/or platelets has changed also helps determine the cause of anemia.

Blood Diseases: White and Red Blood Cells, Platelets and Plasma If you have PV, your bone marrow makes too many red blood cells. It also can make too many white blood cells and platelets. A mutation, or change, in the body's JAK2 gene is the major cause of PV. This gene makes a protein that helps the body produce blood cells. What causes the change in the JAK2 gene isn't known.f you have PV, your bone marrow makes too many red blood cells. It also can make too many white blood cells and platelets.

- Red Blood Cells. The most common symptom of a low red blood cell count is fatigue (tiredness). A lack of hemoglobin in the blood causes fatigue. Hemoglobin is an iron-rich protein in red blood cells.It helps carry oxygen to the body. A low red blood cell count also can cause shortness of breath; dizziness, especially when standing up; headaches; coldness in your hands or feet; pale skin; and chest pain.If you don't have enough hemoglobin-carrying red blood cells, your heart has to work harder to move the reduced amount of oxygen in your blood.hite Blood Cells. White blood cells help fight infections. Signs and symptoms of a low white blood cell count include fevers, frequent infections that can be severe, and flu-like illnesses that linger.

Blood Diseases: White and Red Blood Cells, Platelets and Plasma What Are Blood Cell Disorders? A blood cell disorder is a condition in which there’s a problem with your red blood cells, white blood cells, or the smaller, circulating cells called platelets, which are critical for clot formation. All three cell types form in the bone marrow, which is the soft tissue inside your bones.

What Are Red Blood Cells? Most people don't think about their red blood cells unless they have a disease that affects these cells. Problems with red blood cells can be caused by illnesses or a lack of iron or vitamins in your diet. Some diseases of the red blood cells are inherited. Diseases of the red blood cells include many types of anemia, a condition in which there are too few red blood cells to carry sufficient oxygen throughout the body. People with anemia may have red blood cells that have an unusual shape or that look normal, larger than normal, or smaller than normal.

Anemia Anemia caused by other diseases - Some diseases can affect the body's ability to make red blood cells. For example, some patients with kidney disease develop anemia because the kidneys are not making enough of the hormone erythropoietin to signal the bone marrow to make new or more red blood cells.

Overview Sickle cell anemia is caused by a mutation in the gene that tells your body to make hemoglobin — the red, iron-rich compound that gives blood its red color. Hemoglobin allows red blood cells to carry oxygen from your lungs to all parts of your body.In sickle cell anemia, the abnormal hemoglobin causes red blood cells to become rigid, sticky and misshapen.The sickle cell gene is passed from generation to generation in a pattern of inheritance called autosomal recessive inheritance.emoglobin allows red blood cells to carry oxygen from your lungs to all parts of your body.

Anemia Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that gives blood its red color. This protein helps red blood cells carry oxygen from the lungs to the rest of the body. If you have anemia, your body doesn't get enough oxygen-rich blood.
