Anemia: Causes, Symptoms & Treatment

Anemia

Anemia develops when there are insufficient healthy red blood cells to transport oxygen to your body's organs. As a result, it is typical to feel cold and exhibit signs of exhaustion or weakness. There are numerous varieties of anemia, but the most prevalent is iron deficiency anemia. You can start to alleviate the symptoms of this form of anemia by incorporating iron into your diet.

What is anemia?

Anemia occurs when there are insufficient red blood cells or when the red blood cells do not function properly. Your red blood cells transport oxygen throughout the body. Oxygen powers your cells and provides energy. Without healthy red blood cells that complete their job, your body does not receive the energy it need to function. While some forms of anemia are temporary and mild, others might last a lifetime. Anemia, if not treated, can be fatal.

How does anemia affect my body?

When someone develops anemia, they are considered to be anemic, which means they experience anemia symptoms such as being extremely exhausted or constantly feeling chilly. Anemia affects people differently.

  • Newborns:  Some babies are born with a low red blood cell count. Most neonates do not require medical treatment for anemia, but severe cases may necessitate blood transfusions.

  • Infants may receive less iron than required when they begin eating solid foods. This is because iron in solid food is not as readily absorbed as iron in breast milk or formula. Infants with anemia may appear lethargic.

  • Children grow rapidly between birth and the age of two. Children going through growth spurts require extra iron. Anemia in children can lead to delayed motor skill development and learning difficulties.

  • Women who are pregnant: Pregnant women are more likely to develop iron deficiency anemia, which increases the risk of complications such as premature birth or having babies with low birth weight.

  • Women and persons designated female at birth (DFAB) who have heavy periods (menstrual bleeding) or diseases such as uterine fibroids may experience blood loss and develop anemia.

  • People over the age of 65 are more likely to have iron-deficient diets and certain chronic conditions, both of which increase the chance of getting anemia. If they develop anemia, they may have heart problems or weakness that makes it difficult for them to move around. They may experience perplexity or depression.

  • People with chronic disorders: Certain chronic ailments, such as autoimmune diseases or cancer, may increase the risk of developing anemia. This is chronic disease-related anemia.

 

How common is this condition?

Anemia is extremely widespread, affecting one-third of the global population and over 3 million persons in the United States.

What are the types of anemia?

There are several types of anemia, each of which causes a decline in red blood cell numbers.

Nutritional anemias
  • One of the reasons of vitamin B12 shortage is pernicious anemia, which is an autoimmune disorder that inhibits your body from absorbing vitamin B12.

  • Iron deficiency anemia occurs when your body does not have enough iron to produce hemoglobin. Hemoglobin is the chemical found in your red blood cells that allows them to transport oxygen throughout your body.

  • Megaloblastic anemia is a kind of anemia caused by a lack of vitamin B12 and/or folate.

Inherited anemias
  • Sickle cell anemia alters the shape of your red blood cells, transforming them from round, flexible discs into rigid, sticky sickle cells that impede blood flow.

  • Fanconi's anemia is an uncommon blood condition. Anemia is one of the symptoms of Fanconi anemia.

  • Diamond-Blackfan anemia: This hereditary condition prevents your bone marrow from producing enough red blood cells.

Anemias caused by abnormal red blood cells
  • Hemolytic anemia occurs when red blood cells break down or perish at a quicker rate than usual.

  • Aplastic anemia occurs when the stem cells in your bone marrow do not produce enough red blood cells.

  • Autoimmune hemolytic anemia occurs when your immune system destroys red blood cells.

  • Sideroblastic anemia is characterized by a lack of red blood cells and an excess of iron in the system.

  • Macrocytic anemia occurs when the bone marrow produces abnormally big red blood cells.

  • Microcytic anemia occurs when your red blood cells do not have enough hemoglobin and are smaller than normal.

  • Normocytic anemia:In this type of anemia, you have fewer red blood cells than usual, and those red blood cells do not contain the proper quantity of haemoglobin.

 

Symptoms and Causes

What are the symptoms of anemia?

The most visible anemia symptom is fatigue, which is when you are too fatigued to do your normal tasks. Additional symptoms may include:

  • Shortness of breath (dyspnea) is the sensation that you can't catch your breath or take a deep breath.

  • Dizziness refers to feeling lightheaded or unstable on your feet.

  • Fast or irregular heartbeat (arrhythmia): This occurs when your heart feels like it is racing or skipping beats.

  • Pulsatile tinnitus is characterized by a pounding or "whooshing" sound in one of your ears that may come and go.

  • Headache: Iron-deficiency anemia and anemias induced by low hemoglobin levels can produce headaches.

  • Pale or yellow complexion: Your skin color may appear paler than usual.

  • Chest pain: It may feel as if something is pressing or squeezing your chest.

What is the main cause of anemia?

Some people are born with anemia, while others develop it as a result of chronic conditions. However, iron deficiency anemia, the most prevalent type of anemia, is caused by a poor diet.

Diagnosis and Tests

How do healthcare providers diagnose anemia?

  • Your healthcare physician will quiz you about your symptoms. Anemia occurs when you do not have enough healthy red blood cells, thus they will perform blood tests to check on your red blood cells.

  • A complete blood count (CBC) is a test used by healthcare experts to check all of your blood cells, with a focus on red blood cells. They count your red blood cells and determine their size and form. This test may be used by your healthcare professional to determine your vitamin B12 or B9 levels.

  • Peripheral blood smear: A medical professional examines your red blood cells under a microscope.

Management and Treatment

How do healthcare providers treat anemia?

First, your healthcare professional will evaluate whether your anemia is caused by a poor diet or a more serious medical condition. They may recommend you to a hematologist, a healthcare specialist who specializes in blood diseases. Here are some popular anemia treatments:

  • If you have iron deficiency or pernicious anemia, your doctor may advise you to change your diet or take supplements.

  • If you have anemia due to a chronic ailment, your doctor will treat the underlying reason. They may prescribe a drug to increase red blood cell production.

Providers may employ immunosuppressants or blood transfusions to treat anemias caused by aberrant red blood cells, such as aplastic anemia or hemolytic anemia.

Prevention

Can I prevent developing anemia?

Certain types of anemia, such as sickle cell anemia, hemolytic anemia, and aplastic anemia, cannot be prevented. People with chronic conditions who are at risk of developing anemia should be aware of the symptoms. Eating a nutritious diet can also help prevent nutritional anemia.
