Red blood cells, also known as erythrocytes, are cells that are present in the blood. They perform the function of oxygen transport through hemoglobin to various organs. Anemia is a condition in which your body lacks enough healthy red blood cells. When that happens, the different parts of your body do not get enough oxygen. Anemia causes a drop in hemoglobin, therefore causing fatigue and lethargy.

Anemia can occur due to various reasons, ranging from mild to severe, temporary to permanent. Therefore its treatment depends upon the cause.
Mostly iron supplements can help get rid of anemia because the most common cause for it is iron deficiency. To prevent it, you should eat a healthy diet containing iron. If you have any symptoms of anemia, you should visit a hematologist in Lahore.

What are the Symptoms of Anemia?

The signs and symptoms of anemia may vary from person to person, depending upon the severity. Sometimes, you may not have any symptoms. The common signs and symptoms of anemia are;

Irregular heartbeat
Pale skin
Chest pain
Cold feet and hands

The symptoms of anemia may progress slowly. Therefore you get to know about them gradually.

What are the Causes of Anemia?

There are various causes of anemia. They can be described as;

Iron deficiency

The most common cause of anemia is iron deficiency. To produce hemoglobin, your body needs iron. When it lacks iron, eventually there is less hemoglobin for red blood cells.
Iron deficiency anemia can occur due to bleeding, heavy menstrual periods, cancer of the large bowel, an ulcer in the stomach, or prolonged use of aspirin. To treat it, your healthcare will prescribe an iron supplement.

Vitamins deficiency

Another cause of anemia is a deficiency of vitamins such as folic acid and B12 for the production of healthy red blood cells. When you eat a diet that does not contain enough vitamins, it can lead to anemia.

Anemia that occurs due to the deficiency of vitamin B12 is called pernicious anemia. Some people can not absorb vitamin B 12, hence it can lead to anemia.


Anemia can occur due to inflammatory conditions such as;

Rheumatoid arthritis
Crohn’s disease
Kidney disease

Inflammation can interfere with the production of red blood cells, eventually leading to anemia.

Aplastic anemia

It is a condition when your body does not produce enough red blood cells. If not treated promptly, it can become life-threatening. Aplastic anemia can occur due to;

Certain medicines
Expsoure to toxic chemicals
Autoimmune diseases

Bone marrow diseases

The diseases of the bone marrow such as myeloma and leukemia can cause anemia by affecting the production of red blood cells. Anemia due to these conditions can be acute or gradual. To cope with it, your healthcare provider may order a blood transfusion as a supportive treatment.

Hemolytic anemia

Your body creates and destroys red blood cells. It goes on in a well-mannered cycle. The life span of a red blood cell is 120 days. Hemolytic anemia is a condition when your body destroys red blood cells faster than their life, and production can not meet the loss. Therefore, eventually, anemia occurs due to a shortage of healthy red blood cells. You may inherit it or get it later in life.

Sickle cell anemia

Normally, the red blood cells are disc-shaped. In sickle cell disease, they have the shape of a crescent or a sickle, which causes their clumping and destruction, causing anemia. It is a type of hemolytic anemia that is passed through genes from parents to the offspring. If you have signs and symptoms of anemia, you should visit a hematologist in Karachi.
