Recommended: Short note on anemia
Definition: Anemia is a common condition that afflicts many people around the world. Anemia is a Greek word meaning ‘without blood’. The modern definition of Anemia is any condition characterized by an abnormal decrease in the body’s total red blood cell mass. It is also defined as a condition in which a person has fewer red blood cells than normal and feels very weak and tired.
Anemia Causes: The causes of Anemia are all related to the Red Blood Cells (RBC). It is cause d mainly due to impaired RBC production or increased RBC destruction and is caused due to blood loss and fluid overload. The most common cause of anemia is blood loss, although this does not have any permanent symptoms. Excessive blood loss can be caused by stomach ulcers, hemorrhoids, inflammation of the stomach, cancer, some medications, childbirth, mensuration, surgery and trauma in accidents. Immune reactions, some medications, infections, medical procedures and toxins for example using a heart-lung bypass machine, or hemodialysis can cause hemolysis. Diet and hormones also play a key role in the development of anemia. A diet that lacks iron, Vitamin B12 or folic acid can forestall the body from performing enough red blood cells.
Symptoms of the Disease: When suffers from Anemia, the symptoms are not obvious soon. The symptoms of anemia depend on the condition or according to the cause of the anemia. Lethargy and tiredness are the most public symptoms of anemia and the most pronounced. Lethargy is a mental condition in which a person does not feel like working and fatigue is a physical condition in which a person feels he does not have enough energy to work. Another symptoms are malaise (seems that one is not well), dyspnea (shortness of breath; breathing hard or difficult), poor concentration, palpitations and sensitivity to acold temperatures.
Treatment of the Disease: Anemia is diagnosed through a blood test and once the doctor identifies the cause of anemia there are different treatment options available. Treatments may have dietary changes or supplements, medicines, procedures, or surgery to treat blood loss. The goal of treatment is to modify the average of oxygen that the blood can carry.
Inadequate iron stores in the blood cause iron deficiency anemia. Iron is needed for the production of hemoglobin needed for red blood cells. Hemoglobin is important in the transport of oxygen to the body tissues. In the United States, 10-30% of the entire population suffers from iron deficiency anemia. Women are more likely to be anemic because of poor eating habits and blood loss during menstruation. Thus, many women enter pregnancy with reduced iron stores or some level of anemia. According to multiple studies on anemia and pregnancy o...
Anaemia, which is a low level of oxygen in the blood due to a lack of red blood cells or lack of haemoglobin heart failure, which means your heart is having problem pumping enough blood around your body, usually because the heart muscle has become too weak or stiff to work properly a problem with your heart rate or rhythm, such as atrial fibrillation.
The spleen, an organ on the left side of the abdomen across from the liver, is responsible for filtering the blood for infections and other abnormalities. Normal red blood cells can change shape and squeeze through this filter, but sickled cells get stuck and cannot recirculate through the body, so that the number of circulating blood cells goes down. 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.)
There are many causes of anemia in the body. Some factors include genetics and deficiencies in the diet. Ms. A claims that for the past 10 – 12 years menorrhagia and dysmenorrheal have been a problem for her. Menorrhagia is abnormal and heavy menstrual bleeding during menstruation (Mayoclinic, 2013). Menorrhagia can deplete iron levels in the blood and increase the risk of an individual to have iron deficiency anemia. This is the cause of Ms. A’s anemia. Moreover, Ms. A says that she constantly takes aspirin especially in the summer to prevent stiffness in the joints. Aspirin affects and hinders the production of red blood cells (Mayoclinic, 2013). From the description of anemia given above, the lack of red blood cells, leads to low levels of iron and therefore low levels of hemoglobin which in turn affects the transportation of oxygen and thereby causing shortness of breath. Ms. A’s initial complains of shortness of breath and fatigue is the reason why she went to see the physician.
Sickle cell anemia is a blood disorder that is inherited from both parents in which the body produces abnormally shaped red blood cells. In sickle cell anemia, the hemoglobin in red blood cells links together; resulting in the red blood cells to become rigid and a C-shaped. These deformed cells block blood and oxygen flow in blood vessels. Sickle cells deteriorate quicker than normal red blood cells, which results in anemia.
Sickle cell anemia is an inherited disease in mostly people of Mediterranean, African, or Southeast Asian heritage which occurs when a person inherits the genes for sickle hemoglobin(NHLB). Sickle cell anemia is named from the shape that the red blood cells take because they become a crescent/sickle shape. Normally these red blood cells are flexible and round, but with sickle cell anemia they become rigid and sticky(Mayo Clinic) This shape inhibits the normal functions of red blood cells and they also cause blockages in blood flow to the limbs. The signs and symptoms of the disease vary, ranging from mild symptoms to drastic and hospital inducing health problems. There currently exists no widely available cure for sickle cell anemia, but as time passes and more research is done it is hopeful that there will be a cure.
Blood transfusions allow for infected blood cells to be cycled out and replaced by fresh new blood cells in hope that hemoglobin levels will be restored within the body. When treating a person with liver disease it’s almost routine for them to experience several blood transfusions a month in order to help restore properly working blood cells back into their bodies. Blood transfusions are also a more structurally sound medical procedure when compared to several medications or radiation therapy alternatives, which can in turn cause a number of other problems. Another example of a disease that can be supported by the cycling of blood is Anemia. There several different types of anemia including aplastic, fanconi, hemolytic, and sickle cell anemia. The Mayo Clinic describes Anemia as “condition in which you don't have enough healthy red blood cells to carry adequate oxygen to the body's tissues”. Hematologists have been prescribing their anemia patients with several blood transfusions a month in hopes of training their bodies to make proper working blood cells once again. A study posted in the Journal of Palliative Medicine was conducted on 64 volunteer patients with several different forms of anemia to see if blood transfusions would benefit their hemoglobin values over a 15-day period. It turns out that 95 percent of the patients had some
The problem is that 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.
Yearly, around six hundred to nine hundred people are diagnosed with Aplastic Anemia within the United States. Aplastic Anemia is a autoimmune hematological disorder that causes pancytopenia which is a reduction in major blood components, namely, erythrocytes, leukocytes and platelets. This disease has been labelled as a type of bone marrow failure, that is often due to not one but a variety of disorders that occur simultaneously. Aplastic Anemia can therefore be defined as a bone marrow disorder that is often rare, non contagious, and can often be life threatening.
Vitamin B12 deficiency is common in the United States and often responsible for anemia and neurologic symptoms, particularly in the elderly.
When a person suffers from anemia, they have than normal number of red blood cells. However anemia can also occur if your red blood cells do have an insufficient amount of hemoglobin.
Sickle Cell Anemia is a blood disorder which is passed down from parents to a child. Many people have Sickle Cell Anemia in the U.S and around the world. These people have a wide variety of symptoms, varying from semi-severe to life threatening problems while others live with little to no recognizable symptoms.
Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm). Low ferritin (iron storage molecule) and high TIBC (tota...
