Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.

Is anemia genetic or acquired?

Hemolytic anemia can be inherited or acquired: Inherited hemolytic anemia happens when parents pass the gene for the condition on to their children. Acquired hemolytic anemia is not something you are born with. You develop the condition later.

The last stage is iron deficiency anemia. It is characterized by a low hemoglobin concentration with small (microcytic), pale (hypochromic) RBCs. Symptoms include fatigue upon exertion, weakness, headaches, apathy, pallor, poor resistance to cold temperatures, low physical work capacity, and poor immune function.

Does stress cause anemia?

Sustained stress is another cause of anaemia. Excessive stress hinders the manufacture of hydrochloric acid in your body, which is very important for the integration of iron and proteins. The deficiency of iron is equal to lack of haemoglobin and thus, anaemia.

Why do you get anemia?

Iron deficiency anemia occurs when your body doesn't have enough iron to produce hemoglobin. Hemoglobin is the part of red blood cells that gives blood its red color and enables the red blood cells to carry oxygenated blood throughout your body.

Can anemia Be Cured?

If you have been diagnosed with acute or chronic anemia, know that it can be corrected. A variety of treatments are used to treat anemia, including blood transfusions to replace very low red blood cells (RBCs) from blood loss.

What type of anemia is inherited?

Among the types of anemia that can be inherited are: Sickle-cell anemia. People with sickle-cell anemia have a gene that causes the blood protein hemoglobin to form abnormally. As a result, red blood cells are produced in a sickle shape.

Why do people have anemia?

Many people think of anemia as something that happens because of outside factors, like a poor diet, but in reality several types of anemia are related to glitches in genes, says Christal Murray, MD, a hematologist with Scott and White Hospital in Round Rock, Texas. “Some people inherit genes that, one way or another, cause problems with the blood,” Dr. Murray says.

Why do people with Fanconi anemia have a higher risk of infection?

Besides having the classic signs of anemia, such as fatigue and dizziness, some people with Fanconi anemia are also at greater risk for infection because their bodies don’t produce enough white blood cells to fight germs.

What is the condition where you can't produce intrinsic factor?

Congenital pernicious anemia. This rare type of anemia results when a person is born with an inability to produce intrinsic factor, a protein in the stomach that helps the body absorb vitamin B12. Without vitamin B12, the body cannot make enough healthy red blood cells, causing you to become anemic. The lack of vitamin B12 can lead to other complications, like nerve damage, memory loss, and an enlarged liver. Like other forms of pernicious anemia, this condition is usually treated with vitamin B12 supplements, which may need to be taken for a lifetime.

What is the disease that is passed from parent to child through genes?

Hereditary spherocytosis. This disease, which is usually passed from parent to child through the genes, is characterized by abnormal red blood cells called spherocytes that are thin and fragile. These cells cannot change shape to pass through certain organs as normal red blood cells do, so they stay in the spleen longer, where they are eventually destroyed. The destruction of the red blood cells causes anemia. Most people with hereditary spherocytosis have only mild anemia, but stresses on the body from infection can cause jaundice and even a temporary halt in the bone marrow’s production of blood cells.

Why are some patients at greater risk for acute myeloid leukemia?

Some patients are also at greater risk for acute myeloid leukemia, a type of blood cancer, because their bone marrow makes a large number of immature white blood cells, preventing the production of normal blood cells. Hereditary spherocytosis.

How does anemia affect the body?

To further ensure oxygen supply to the organs, the organism typically reacts by increasing the heart rate to pump blood faster through the circulation. However, this makes it easier for the body to reach its stress limits.

Can sickle cell anemia be inherited?

According to the US Department of Health and Human Services and Genetics Home Reference, sickle cell anemia can be inherited in an autosomal recessive pattern.
