what does it mean when you have small red blood cells?

Microcytosis is a term used to describe red blood cells that are smaller than normal. Anemia is when you have low numbers of properly functioning red blood cells in your body. In microcytic anemias, your body has fewer red blood cells than normal. The red blood cells it does have are also too small.

Anemia is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Having anemia can make you feel tired and weak. There are many forms of anemia, each with its own cause. Anemia can be temporary or long term, and it can range from mild to severe.

Even worse, it can impair the bone marrow's ability to make red and white blood cells, causing severe anemia and dangerously low numbers of white blood cells. When the number of white blood cells is reduced, your body may have difficulty fighting infections.

When the MCV value is increased, the RBC is said to be abnormally large, or macrocytic. This is most frequently seen in megaloblastic anemias (e.g., vitamin B12 or folic acid deficiency). When the MCV value is decreased the RBC is said to be abnormally small, or microcytic.

Macrocytic anemia means that the red blood cells are larger than normal. In microcytic anemia, the cells are smaller than normal. We use this classification because it helps us to determine the cause of the anemia. The most common causes of macrocytic anemia are vitamin B-12 and folate deficiency.

Hypochromic means that the red blood cells have less hemoglobin than normal. Low levels of hemoglobin in your red blood cells leads to appear paler in color. In microcytic hypochromic anemia, your body has low levels of red blood cells that are both smaller and paler than normal.

In many cases, a low hemoglobin count that's only slightly lower than normal doesn't affect how you feel. A low hemoglobin count that's more severe and causes symptoms might mean you have anemia.

Anemia is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Having anemia can make you feel tired and weak.

Sickle cell disease is a condition in which red blood cells are not shaped as they should be. Red blood cells look like round discs. But in sickle cell disease, they're shaped like sickles, or crescent moons, instead. These sickle shaped cells get stuck together and block small blood vessels.

Microcytic anemia is defined as the presence of small, often hypochromic, red blood cells in a peripheral blood smear and is usually characterized by a low MCV (less than 83 micron 3). Iron deficiency is the most common cause of microcytic anemia.

The red cells in your blood can be A, B, AB, or O. The red blood cells also have a protein that is called Rh on the surface of the cell. Your blood can be Rh positive, which means that you have the Rh protein, or Rh negative, which means that you do not have the Rh protein.

Red blood cell, also called erythrocyte, cellular component of blood, millions of which in the circulation of vertebrates give the blood its characteristic colour and carry oxygen from the lungs to the tissues. The mature human red blood cell is small, round, and biconcave; it appears dumbbell-shaped in profile.

A low mean corpuscular hemoglobin concentration (MCHC) shows that someone's red blood cells do not have enough hemoglobin. Hemoglobin is an iron-rich protein, and a lack of it may indicate anemia. Hemoglobin is responsible for the red color in blood and for circulating oxygen around the body.

White blood cell count (WBC) This test measures the number of white blood cells in a drop (microliter) of blood. A low WBC count may be due to chemotherapy, a viral infection, a toxic reaction, or a process in the bone marrow that limits the body's ability to make normal WBCs.

Diseases and conditions that cause your body to produce fewer red blood cells than normal include: Aplastic anemia. Cancer. Certain medications, such as antiretroviral drugs for HIV infection and chemotherapy drugs for cancer and other conditions.

When you have a low blood count, this means your bone marrow is not making enough of one type of blood cells. Doctors call a low blood count cytopenia .

A low red blood cell count is called anemia. If you have a low red blood cell count, you may: Feel a little tired or very tired.
