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.

Diet low in iron, or some vitamins or minerals. Surgery or accident with blood loss. Long-term illnesses, such as infections, or kidney or liver disease. Family history of an inherited type of anemia, such as sickle cell anemia.

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 .

This type of anemia is not caused by too little iron in the blood; it's caused by not having enough red blood cells. In fact, taking iron supplements could harm a person with sickle cell disease because the extra iron builds up in the body and can cause damage to the organs.

In iron deficiency, low levels of hemoglobin in red blood cells mean that not enough oxygen can reach the brain. As a result, blood vessels in the brain can swell, causing pressure and headaches ( 12 ).

Low Hemoglobin. Hemoglobin, the substance that gives color to red blood cells, is the substance that allows for the transport of oxygen throughout the body. Low hemoglobin levels lead to anemia, which causes symptoms like fatigue and trouble breathing.

Tiredness that interferes with your daily activities. When your red blood cell count gets too low, you may be overcome with fatigue. Anemia often leads to fatigue and irritability. However, having a chronic autoimmune disease like ITP can heighten fatigue as well.

Anemia (low red blood cell count), whether it occurs acutely from bleeding or gradually for a variety of reasons, can cause fainting because there aren't enough red blood cells to deliver oxygen to the brain.

The major causes of this type are iron deficiency (low level iron) anemia and thalassemia (inherited disorders of hemoglobin). If the red blood cells size are normal in size (but low in number), this is called normocytic anemia, such as anemia that accompanies chronic disease or anemia related to kidney disease.

A low RBC count may indicate anaemia, bleeding, kidney disease, bone marrow failure (for instance, from radiation or a tumour), malnutrition, or other causes. A low count may also indicate nutritional deficiencies of iron, folate and vitamin B12.

Excessive alcohol use can affect the hematologic system, which is made up of the blood, spleen, bone marrow, and the liver. It can cause your red blood cell count to be abnormally low, which is a condition called anemia. Symptoms of anemia include fatigue, shortness of breath, and lightheadedness.

A low hemoglobin count can be associated with a disease or condition that causes your body to have too few red blood cells. This can occur if: Your body produces fewer red blood cells than usual. Your body destroys red blood cells faster than they can be produced.

Low blood counts can have many causes, including vitamin deficiencies, bleeding, and rare bone marrow failure diseases like aplastic anemia , MDS and PNH. If your blood tests are abnormal, your doctor may do other blood tests or take a sample of your bone marrow to find out why.

As CLL becomes more advanced, the cancer cells can replace the bone marrow's normal blood-making cells, which can cause the marrow to produce fewer red cells, white cells and platelets with these results: A low number of red blood cells ( anemia ) can lead to feeling very tired, shortness of breath and pale skin.

A lack of the vitamin B-12, folate and iron can keep your body from producing enough red blood cells (anemia), causing low blood pressure.

That lack of oxygen-rich blood in your body can make you feel tired and weak. While iron deficiency is the most common cause of anemia, other causes include heavy periods, sluggish bone marrow, vitamin B12 deficiency or a lack of folate in the diet, says Dr.

If you have a low red blood cell count, you may: Feel a little tired or very tired. Feel less alert or have trouble concentrating. Have a loss of appetite or lose weight.
