Anemia is a condition in which the patient’s body lacks enough healthy red blood cells to carry enough oxygen to the tissues of the body. Experts know anemia as a fall in one or more measurements of red blood cells. Which:
The concentration of hemoglobin is the main carrier of oxygen gas in the blood.
Hematocrit or hemodialysis is the blood deposition or the percentage of red blood cell size of the total blood volume.
Red blood cell count is the number of red blood cells in a certain predefined size of the total blood volume.
Definition of anemia by sex.
The definition of anemia by sex is as follows:
Male: known as anemia among males with less than 13.5 g / dL for hemoglobin concentration, and the values of the values of less than 41 percentage of hematocrit.
Female: Female anemia is known to have values less than 12 g / dL for hemoglobin concentration, and values less than 36% for hematocrit.
Red blood cells contain hemoglobin, an iron-rich protein that gives blood its red color. Hemoglobin Red blood cells can transfer oxygen from the lungs to the rest of the body. The transfer of carbon dioxide from the body back to the lungs, so that it can be removed from the body during the exhalation process.
Most blood cells, including red blood cells, are constantly produced in the bone marrow. It is a red spongy substance, found inside the large bone cavities in the body.
In order to produce hemoglobin and red blood cells, the body needs iron and other minerals. When a person suffers from anemia, his body does not produce enough red blood cells. Many are lost or destroyed more quickly than they can produce new blood cells.
Symptoms of anemia.
Multiple anemia symptoms are common because hypoxia affects all body cells. These symptoms vary depending on the severity of the poverty. The most important of these symptoms are:
Feeling weak, tired or tired.
Difficulty concentrating and feeling dizzy.
The patient suffers from shortness of breath and headache, especially during exercise or exertion.
Drought and hardening nails.
Cold weather, due to lack of iron stock.
Feeling high in body temperature, and being unable to tolerate the warm atmosphere.
The patient feels a general numbness in his body, especially in his hands, or his sense of acupuncture in his body.
Craving to eat other things other than food, such as dust, wax, grass, paper, ice, and others. These symptoms occur in the patient with anemia because of the need for iron, called qata, or lust for the oddity.
Leg pain syndrome is more common in people with anemia due to iron deficiency.
Behavioral disorders in children and low school performance in school-age children.
The patient suffers from neurological symptoms, the most important of which is numbness throughout the body, in cases of anemia due to vitamin B12 deficiency.
Loss of memory, but this presentation is not always, but is a little appearance.
Depression, hallucinations, change in personality.
Difficult to consider, but in rare cases.
Symptoms of severe anemia.
Rapid heart palpitations.
Heart failure, because it tries to compensate for the lack of blood needed to carry oxygen. Where the beating beats, thus increasing the possibility of heart failure.
Difficulty breathing, and increased breathing times.
When performing a clinical examination it is noticed that the patient suffers from pallor. This is known by looking at the conjunctiva, and at the lines in the soles of the palm.
Inflammation in the mouth especially the tongue area.
When you examine the nails, there are abnormalities, especially in the case of iron deficiency in the blood, and are very fragile.
The patient suffers from yellowing of the skin in case the cause of broken blood anemia.
There are some abnormalities in the bones, and this is in the case of thalassemia.
Diagnosis of anemia.
In general, doctors require a complete blood test in primary blood tests when the diagnosis the anemia. The laboratory results give the number of red blood cells, hemoglobin concentration, and automatic counters. It also measures the size of red blood cells by measuring flow cytometry, which is important in distinguishing the causes of anemia.
There are four criteria the patient must measure when testing anemia:
The number of red blood cells.
The concentration of hemoglobin.
Medium ball size.
The average diameter of red blood cells.
If you do not obtain the diagnosis, bone marrow screening allows direct examination of red cells.
Factors that increase the risk of anemia include:
Diet low in iron, vitamins, and minerals.
Blood loss from surgery.
A family history, such as sickle cell anemia or thalassemia.
