 Anemia

Anemia is a condition that occurs when your blood produces fewer healthy red blood cells than is typical. Your body does not receive enough oxygen-rich blood if you have anemia. When there aren't sufficient healthy red blood cells to deliver oxygen to your body's organs, anemia develops. As a result, feeling cold and signs of fatigue or weakness are frequent. Anemia comes in a variety of forms, but iron-deficiency anemia is the most prevalent. By increasing your intake of iron, you can start to reduce the symptoms of this kind of anemia. . You may feel exhausted or weak due to a lack of oxygen. Moreover, you can get headaches, nausea, or shortness of breath. Over 3 million Americans have anemia, as stated by the Department of Health and Prevention external link.

Causes of anemia

There are various causes of different forms of anemia.

Anemia due to iron deficiency

 A lack of iron in your body is the main cause of this type of anemia. To produce hemoglobin, your bone tissue needs iron. Your body can't make adequate hemoglobin for red blood cells without enough iron.

Many pregnant women develop this type of anemia without iron supplements. It can also be brought on by blood loss from heavy monthly flow, stomach or small intestine ulcers, large bowel cancer, and regular use of various over-the-counter painkillers, particularly aspirin, which can irritate the stomach lining and lead to blood loss. To stop a repetition of the iron deficit, it's critical to identify the source of iron deficiency.

Anemia due to vitamin insufficiency

 To make sufficient healthy red blood cells, your body also requires folate and vitamin B-12 in addition to iron. Reduced formation of red blood cells can result from a diet deficient in all of these essential nutrients. Some individuals who have enough B-12 cannot absorb the vitamin. Pernicious anemia, commonly known as vitamin deficiency anemia, may result from this.

Inflammation-induced anemia

Red blood cell production can be hampered by a number of conditions, including cancer, HIV/AIDS, rheumatoid arthritis, kidney illness, Crohn's disease, and other acute or chronic inflammatory diseases.

Bone Marrow Failure (Aplastic anemia)

The stem cells in aplastic anemia are harmed. As a result, the bone marrow is either aplastic (empty) or has a small number of blood cells (hypoplastic). This uncommon, potentially fatal anemia develops when your body fails to create sufficient red blood cells. Aplastic anemia can be brought on by infections, some medications, autoimmune disorders, and exposure to hazardous substances.

Diseases of the bone marrow that can cause anemia

 Anemia can be brought on by a number of illnesses that interfere with the bone marrow's ability to produce blood, including leukemia and myelofibrosis. These cancers' and cancer-like illnesses' effects range from minor to potentially fatal.

Anemia due to hemolysis

When red blood cells are lost more quickly than bone marrow can produce new ones, this group of anemias forms. Red blood cell breakdown is accelerated by some blood conditions. Hemolytic anemia can be inherited or acquired later in life. The sponge-like tissue found inside your bones, known as bone marrow, is where red blood cells are created. Hemolysis, a natural process in your body, helps to eliminate damaged or outdated red blood cells from the spleen and other organs. Anemia caused by excessive hemolysis happens when there are not enough red blood cells in the body.

Anemia with sickle cells

Hemolytic anemia is an inherited and occasionally serious illness. Red blood cells are forced to take on an unusual crescent (sickle) shape as a result of a faulty form of hemoglobin. There is a persistent deficit of red blood cells as a result of these abnormal blood cells dying too soon. The aberrant form of hemoglobin known as hemoglobin S makes red blood cells stiff and sickle-shaped. This condition, also known as sickle cell anemia, is typically the most severe type of the illness.
