The Causes of Anemia
There are many patients with anemia, and most of them are women. There are different the causes of anemia, and the most common the causes of anemia are usually the following.
1. Iron is an important trace element in the human body, and it is also an indispensable factor in the process of hematopoiesis. Lack of iron intake in the diet is a common the causes of anemia. When the human body lacks vitamin B12, anemia can also occur. Especially in people with more picky eaters and partial eclipses, the body lacks iron, protein, vitamin B12 and other elements required for hematopoiesis.
2. Some patients do not lack iron in their diets, but the body's poor absorption and loss of iron are the causes of anemia. For example, poor gastrointestinal absorption, ulcer disease, hemorrhoids, heavy menstrual flow in women, functional uterine bleeding, etc., can all lead to the appearance of anemia.
3. A large amount of blood loss in the human body can also cause anemia. The causes of anemia is also very likely to cause anemia due to factors such as surgery and trauma.
Anemia can be due to a condition present at birth (congenital) or to a condition you develop (acquired). Anemia occurs when your blood doesn't have enough red blood cells.
This can happen if:
- Your body doesn't make enough red blood cells
- Bleeding causes you to lose red blood cells more quickly than they can be replaced
- Your body destroys red blood cells
What red blood cells do to the cause of anemia?
Your body makes three types of blood cells — white blood cells to fight infection, platelets to help your blood clot, and red blood cells to carry oxygen from your lungs to the rest of your body and carbon dioxide from the body back to the lungs.
Red blood cells contain hemoglobin — an iron-rich protein that gives blood its red color. Hemoglobin enables red blood cells to carry oxygen from your lungs to all parts of your body and to carry carbon dioxide from other parts of the body to your lungs to be exhaled.
Most blood cells, including red blood cells, are produced regularly in your bone marrow — a spongy material found within the cavities of many of your large bones. To produce hemoglobin and red blood cells, your body needs iron, vitamin B-12, folate and other nutrients from the foods you eat.
Different types of anemia have different the causes of anemia. They include:
-
The causes of Iron deficiency anemia. This most common type of anemia is caused by a shortage of iron in your body. Your bone marrow needs iron to make hemoglobin. Without adequate iron, your body can't produce enough hemoglobin for red blood cells.
Without iron supplementation, this type of anemia occurs in many pregnant women. It's also caused by blood loss, such as from heavy menstrual bleeding; an ulcer in the stomach or small bowel; cancer of the large bowel; and regular use of some pain relievers that are available without a prescription, especially aspirin, which can cause inflammation of the stomach lining resulting in blood loss. It's important to determine the source of iron deficiency to prevent recurrence of the anemia.
- The causes of Vitamin deficiency anemia. Besides iron, your body needs folate and vitamin B-12 to produce enough healthy red blood cells. A diet lacking in these and other key nutrients can cause decreased red blood cell production. Some people who consume enough B-12 aren't able to absorb the vitamin. This can lead to vitamin deficiency anemia, also known as pernicious anemia.
- The causes of Anemia of inflammation. 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.
- The causes of Aplastic anemia. This rare, life-threatening anemia occurs when your body doesn't produce enough red blood cells. Causes of aplastic anemia include infections, certain medicines, autoimmune diseases and exposure to toxic chemicals.
- The causes of Anemias associated with bone marrow disease. A variety of diseases, such as leukemia and myelofibrosis, can cause anemia by affecting blood production in your bone marrow. The effects of these types of cancer and cancer-like disorders vary from mild to life-threatening.
- The causes of Hemolytic anemias. This group of anemias develops when red blood cells are destroyed faster than bone marrow can replace them. Certain blood diseases increase red blood cell destruction. You can inherit a hemolytic anemia, or you can develop it later in life.
- The causes of Sickle cell anemia. This inherited and sometimes serious condition is a hemolytic anemia. It's caused by a defective form of hemoglobin that forces red blood cells to assume an abnormal crescent (sickle) shape. These irregular blood cells die prematurely, resulting in a chronic shortage of red blood cells.
What are the dangers of the causes of anemia?
Symptoms of anemia include long-term pale skin and no blood, loss of appetite, weak body functions, and often feel fatigued. Most people often do not pay attention to anemia, which leads to more and more serious diseases. If long-term anemia is not treated, it will cause a lot of unnecessary troubles to the body, so what are the consequences of long-term anemia on the body?
Firstly dangers of the causes of anemia, people with long-term anemia will affect the normal development of the human body, especially in adolescent children. At this time, when the body is growing up and growing, if the body is growing up, if the body is long-term anemia will lead to nutritional deficiency, mainly because anemia can lead to heart failure and liver failure. The splenomegaly and many other factors add up to affect the normal physical development of a child.
Secondly dangers of the causes of anemia, people with long-term anemia will cause the function of organs in the body to decline, which affects the body's hematopoietic function and insufficient blood supply to the myocardium. Therefore, patients with long-term anemia often feel heart palpitations and chest tightness. This is the symptom of organ function decline. If you don’t step up treatment at this time, you will regret it.
Thirdly dangers of the causes of anemia, long-term anemia can seriously affect one’s normal life, often dizzy, unable to do too heavy physical work, unable to concentrate when doing things, and the body is extremely prone to fatigue. In severe cases, it can cause shock and other symptoms. Moreover, long-term anemia can also bring many complications to the body, such as poor gastrointestinal function, mental sensitivity and other discomfort symptoms.
The consequences of long-term anemia are very serious, so people with anemia should treat anemia as a serious matter from now on. They should go to the hospital in time and pay more attention to blood and iron supplements in daily life. For example, eat more red dates, black beans, spinach, lean meat and other foods. In addition, pay more attention to rest to ensure a good quality of sleep.
