Why do we need B12?
We require vitamin B12 for proper nutrient absorption within the small intestine. It also is a key player for red blood cell production. Without a suitable amount of vitamin B12, we may see this production decrease. As a result, neurological and coordination problems, anemia, and of course, poikilocytosis can occur.

We will look at the different types of poikilocytosis based on the composition of the red blood cells. 1. Teardrop Cell. Just as the name implies, the red blood cell forms a teardrop shape with a tip at one end. A condition known as myelofibrosis with myeloid metaplasia can cause these teardrop-shaped cells to develop.
Why is B9 important for pregnancy?
Vitamin B9, also referred to as folic acid, is also essential for the production of red blood cells . We often see a lack of this vitamin in pregnancy. It also affects more women than men as it feeds the metabolic requirements and affects the body’s stress and hormone effects.
Sickle cells
Sickle cells, also called drepanocytes, are crescent-shaped and longer than normal RBCs. This type of poikilocytosis is a common symptom of sickle cell diseases, such as sickle cell anemia and hemoglobin S-thalassemia.
Target cells
Target cells, also called codocytes, have a shape that resembles a bullseye. These cells are typically the result of the following:
Spherocytes
Spherocytes are small, dense cells that do not have the lighter colored center that is present on a normal RBC. Spherocytes are usually the result of the following conditions:
Elliptocytes
Elliptocytes, often called ovalocytes, have an oval shape with blunt ends. Elliptocytes are a common feature of the following conditions:
Echinocytes
Echinocytes, sometimes called burr cells, have thorny projections called spicules that outline the cell membrane. Echinocytes are present in several conditions, including:
Acanthocytes
Acanthocytes, often called spur cells, look similar to echinocytes because both cell types have spicules on the edge of the cell membrane. However, acanthocytes tend to have fewer spicules than echinocytes, and these projections are typically less evenly spaced. Acanthocytes commonly have an association with:
Dacrocytes
Dacrocytes, also called teardrop cells, have both a round end and a pointy end. They are present in conditions such as:
Why is poikilocytosis a nutritional deficiency?
Nutritional deficiency in poikilocytosis is always because of iron and folic acid deficiency. ( 11) These can sometimes deform the RBCs structure. This deficiency can lead to structural deformity of RBCs, which often leads to the condition of poikilocytosis.

What are the different types of poikilocytes?
Some of the common poikilocytes are burr cells, target cells, teardrop cells, spur cells and keratocytes, and the elliptocytes. ( 5) The shape and size of each of these poikilocytes vary from each other.
Why is circulation a problem in poikilocytosis?
Because of the abnormally shaped cells in poikilocytosis, blood circulation becomes a major problem. The normal size of the blood cells is small and circular in shape. Therefore, blood cells easily carry oxygen and pass through the tiniest blood vessel without having any problem.
How long does it take for a person to get back to normal blood?
Nutrients get absorbed in red blood cells, and it is possible to get back the normal RBCs in blood after a few weeks.

Definition of Poikilocytosis. Poikilocytosis is a rare blood disorder wherein there is an increase in the number of poikilocytes in the blood. Normally, a red blood cell (RBC) has a shape resembling a disk, which is round and flat. Its middle part is also thinner than its edges.
What are the nutrients needed to produce red blood cells?
The vital nutrients necessary for the production of red blood cells are iron, folic acid (B9), and cobalamin (B12). Vitamin B12 is necessary for the absorption of folic acid. A deficiency in folic acid may result in low levels of hemoglobin. This protein or blood component is vital to produce mature RBCs.
What to do if your RBC is abnormal?

· The RBC has a teardrop shape. · The RBC is smaller than its normal size, which is six to eight µm.
What causes hemoglobin to be low?
A deficiency in ir on may also affect the production of hemoglobin. Some medical conditions such as celiac disease, tropical sprue, and regional enteritis can affect the absorption of nutrients such as folic acid and iron. Eventually, this may cause nutrient deficiency leading to the formation of abnormal blood cells.
What test is used to determine hemoglobin levels?
As such, your doctor may order a hemoglobin or MCHC test wherein the technician will measure the concentration of your hemoglobin levels. Depending on your results, the doctor may order additional tests such as the bone marrow test.
What foods should I eat to prevent a swollen ear?
Thus, it is crucial to eat foods rich in folic acid and cobalamin such as meat products, soy products, eggs, lentils, almonds, beets, spinach, cabbage, broccoli, and whole grains.
