Anemia occurs when the body does not have the required red blood cells to carry oxygen to other organs. The result of this would be fatigue, weakness in the body, and a perennial sense of feeling cold. In addition to this. the skin turns pale due to lack of hemoglobin and oxygen.

Cause of anemia 
One of the most common reasons a person gets anemia is low or deficiency of iron in the body. It is prudent to note that the body needs iron in order to make hemoglobin, which in turn, transports oxygen all through the body.

It is researched that there are over 400 types of anemia and they are largely categorized into three groups as follows:

1. Blood loss
This is caused largely due to bleeding over a period of time. It happens so slowly that you may not even notice. Some of the causes include ulcers, hemorrhoids, and cancer.

2. Faulty or reduced production of red cells
A situation where the body does not create enough blood cells that are ideally required to function in balance. This is largely caused due to a lack of vitamins and essential minerals in the blood. Some of the conditions in this category include bone marrow problems, vitamin-deficiency anemia, and sickle cell anemia.

3. Destruction of red blood cells due to various reasons causing anemia
This is an outcome of what is referred to as hemolytic anemia, where the blood cells are extremely fragile and cannot handle the stress of traveling and transporting through the body and eventually burst. They are largely caused due to the attack by the immune system and are also largely passed through genes.

Types of anemia 
Some of the commonly known anemia are as follows:

1. Sickle cell anemia 
The shape of the blood cells is faulty in this case. They are in the form of a sickle and could cause clogs in the blood vessel and eventually damage them.

2. Pernicious anemia 
When the body does not absorb enough B12, it cannot make required healthy blood cells.

3. Hemolytic anemia 
When a person acquires certain types of disease (that is not present during birth but acquired during one’s lifetime), it makes the body produce deformed red blood cells that die off quickly.

4. Iron deficiency anemia 
This is quite popular among the vegetarian or vegan community, who do not really have enough iron from the food they consume. Iron is largely present in meat, seafood, and poultry. However, there are plenty of methods for vegetarians to get their source of iron if their meal is planned accordingly.
