Anemia : Causes and Symptoms

Anemia : Causes and Symptoms
Anemia can hardly be called a disease, but rather a condition of the body, which is called anemia.But that does not mean in the literal sense, that the blood is really small - it is reducing the content of red blood cells.What are the symptoms and causes of anemia?

main cause of anemia

Red blood cells - red blood cells, which in the adult form in the bone marrow of the spine, skull and ribs, and account for 85% of the blood tissue.Having finished their life cycle, a red blood cell is destroyed (a process called hemolysis) in the liver and spleen.

The lifespan of red blood cells does not exceed 120 days (four months), the reduction of this period can cause anemia.

erythrocyte undergoes several stages Development Reports, and getting into the bloodstream, provides the transport function - deliver from the lungs to the tissues of the hemoglobin, the iron-containing pigment, which, in fact, associated with oxygen.

Lack of iron in the body leads to reduced levels of hemoglobin and thus - to iron defic

iency anemia.

Please note that the hemoglobin concentration vary depending on gender and age, so "normal" may be different indicators.

Other causes of anemia

anemia does not develop by itself, and is always a symptom - independent or concurrent - many internal, hereditary or acquired diseases, in particular diseases of the digestive tract, liver and kidneys.It can be infectious and oncological diseases associated with malabsorption, autoimmune conditions.

However, anemia is not always signal an underlying disease, it can occur in periods of human life associated with changes in the physiological state.

example, women - during pregnancy and breastfeeding, teenagers - at puberty and enhanced growth in the elderly - during menopause and hormonal changes.Anemia can be due to the nature of food (not only iron deficiency, and vitamins), surgery, and other factors.

Types of anemia

Classifications of anemia, there are several, they all include a variety of species - depending on the factor.

The main types of anemia associated with blood loss

  • violation
  • increased blood formation krovorazrusheniem.

Each of these states has its own causes and treatments.Determine the type of anemia can help blood and other laboratory tests.Symptoms of anemia

Complaints for anemia may be different, depending on its type and severity, as well as on the patient and his individual peculiarities.

However, all have in common symptoms of anemia.Weakness, fatigue, decreased performance, irritability, drowsiness observed in anemic patients, explains the "fatigue" of organs and tissues receive less oxygen due to low hemoglobin levels.

This is largely due to dizziness, headaches, tinnitus, flashing "flies" in front of the eyes -

common symptoms of anemia while reducing the level of the same hemoglobin increased load on the heart: to provide normal access of oxygen to the tissues, it has to"pump" more blood.

With this in mind, it becomes clear why palpitations with little physical exertion or even at rest, and it is clear where it came from shortness of breath after overcoming two flights of stairs.

often the first complaint in elderly patients with coronary heart disease is more frequent angina attacks.

However easy and sometimes moderate anemia can occur without obvious symptoms - latent.

Suppose that you lead a moderately active lifestyle and at the same time you have a healthy heart and lungs.In this case, you do not feel a decrease in hemoglobin and characteristic symptoms of anemia, until the iron content is very low.

Incidentally, the iron level could be reduced without severe anemia, which in turn may develop very slowly.

Over time, as more and more will be reduced hemoglobin, the signs and symptoms of anemia will be shown and may even increase.Given that anemia may be accompanied by some life-threatening diseases such as cancer, it is useful to periodically, every six months, blood tests.

Diagnostics

anemia diagnosis of anemia in pevuyu turn is based on a laboratory study of blood.The level of hemoglobin, red blood cells, their size and hemoglobin saturation, hematocrit (the total volume of red blood cells), ESR (erythrocyte sedimentation rate), the number of white blood cells and their composition - all this will show a complete blood count.

detect and confirm laboratory anemia - is half the battle.The main thing - to identify the cause and pathogenesis (ie mechanisms of the emergence and development of the disease and some of its manifestations) of this state and not "gang up" on zhelesoderzhaschie drugs whose utility - a separate issue.

appoint itself and uncontrolled intake of such funds is ineffective and even dangerous in some cases.It can erase the clinical manifestations and lead to late recognition of a number of diseases.

For example, some collagen (a group of diseases characterized by systemic lesions of connective tissue), malignant tumors, chronic inflammatory processes in the initial period are diagnosed only symptom - anemia.Therefore, you must first determine the nature and cause of the anemia, and only then assign the appropriate treatment.
