The two most common causes are chronic diseases (such as ulcers, liver or kidney disease, hypothyroidism, inflammation of the stomach or intestines, and cancer) and iron deficiency. Deficiencies in vitamin B12 or folate are not as common. Certain medications can also contribute to anemia.
Certain diseases — such as cancer, HIV / AIDS, rheumatoid arthritis, kidney disease, Crohn’s disease and other acute or chronic inflammatory diseases — can interfere with the production of red blood cells. Aplastic anemia. This rare, life-threatening anemia occurs when your body doesn’t produce enough red blood cells.
The most common cause of hypovolemic shock is blood loss when a major blood vessel bursts or when you’re seriously injured. This is called hemorrhagic shock. You can also get it from heavy bleeding related to pregnancy, from burns, or even from severe vomiting and diarrhea.
You can lose red blood cells through bleeding. This can happen slowly over a long period of time, and you might not notice. Causes can include: Gastrointestinal conditions such as ulcers, hemorrhoids, gastritis (inflammation of your stomach), and cancer.
Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study. Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study in CMAJ (Canadian Medical Association Journal).
Symptoms that might indicate a serious condition A low WBC count can be serious because it increases your risk of developing a potentially life-threatening infection. Seek prompt medical care if you have a low WBC count and have signs of an infection, such as a fever, swollen lymph nodes, sore throat, or skin lesions.
So if you lose blood, you lose some iron. Women with heavy periods are at risk of iron deficiency anemia because they lose blood during menstruation. Slow, chronic blood loss within the body — such as from a peptic ulcer, a hiatal hernia, a colon polyp or colorectal cancer — can cause iron deficiency anemia.
Your body will replace the blood volume (plasma) within 48 hours. It will take four to eight weeks for your body to completely replace the red blood cells you donated. The average adult has eight to 12 pints of blood.
when there is sudden loss of blood from body, the organ which supplies blood is Liver.
These stages are described in ATLS as follows:
These symptoms include:
Signs and symptoms of internal bleeding
When blood loss is rapid, blood pressure falls, and people may be dizzy. When blood loss occurs gradually, people may be tired, short of breath, and pale. Stool, urine, and imaging tests may be needed to determine the source of bleeding.
The most common causes of anemia in the elderly are chronic disease and iron deficiency. Vitamin B12 deficiency, folate deficiency, gastrointestinal bleeding and myelodysplastic syndrome are among other causes of anemia in the elderly.
Without treatment, the median survival time for myelodysplastic syndromes range from less than a year to approximately 12 years, depending on factors such as number of chromosome abnormalities and level of red blood cells.
Anemia if not treated for a long period can lead to serious complications. These include heart failure, severe weakness and poor immunity. Anemia is a medical condition in which the person does not have enough red blood cells or RBCs.
