Decreased production of hemoglobin (e.g., thalassemia) Kidney failure-severe and chronic kidney diseases lead to decreased erythropoietin production, a hormone produced by the kidneys that stimulate RBC production by the bone marrow. Bone marrow disorders such as aplastic anemia, myelodysplastic syndrome, or cancers such as leukemia, lymphoma, multiple myeloma, or other cancers spread to the marrow. Damage to the bone marrow from, for example, a toxin, radiation or chemotherapy, infection, or drugs. Excessive loss of blood from, for example, severe trauma, or chronic bleeding from sites such as the digestive tract (e.g., ulcers, polyps, colon cancer), the bladder or uterus (in women, heavy menstrual bleeding, for example). Chronic inflammatory diseases or conditions. Nutritional deficiencies such as iron, folate, or B12 deficiency. It can also be defined as a lowered ability of the blood to carry oxygen. A low count in RBC may indicate hemorrhage or bleeding, failure in the bone marrow or a tumor, or anemia.Look for Possible Connected Biomarkers: Low hematocrit + low RBC count + low hemoglobin indicates anemia.Īnemia is usually defined as a decrease in red blood cells (RBCs) or hemoglobin in the blood. But of course, these two counts are different. What does it mean if your RBC and hemoglobin are low?īut if you have low hemoglobin count, that could make your RBC count either normal or abnormal. A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women. If it gets more severe and causes symptoms, your low hemoglobin count may indicate you have anemia. What is considered dangerous in low hemoglobin? Kidney disease, liver disease (cirrhosis), cancer, and medications used to treat cancer can also cause low levels. Low RBC counts, hemoglobin and hematocrit levels can be caused by other things too, such as a lot of bleeding or malnutrition (not enough nutrients in the food eaten). Excess blood loss from surgery, or even frequent blood draws over time, can also lead to a low red blood cell count - sometimes an acute one. The bleeding can happen rapidly - for example, in an acute hemorrhage caused by an injury. The most common cause of red blood cell loss is bleeding.
Rarely, chronic blood loss from hemorrhoids may cause anemia, in which you don’t have enough healthy red blood cells to carry oxygen to your cells. Can hemorrhoids cause low red blood cell count?Ĭomplications of hemorrhoids are rare but include: Anemia. If you test positive for leukemia, your doctor will perform a biopsy of your bone marrow to determine which type you have. Does low red blood cell count mean leukemia?Ībnormal levels of white blood cells and abnormally low red blood cell or platelet counts can also indicate leukemia. Cancers that involve the marrow space, such as leukemia or lymphoma, compete with the marrow’s function and interfere with normal red blood cell production. What cancers are associated with anemia? Red blood cells. What cancers cause low red blood cell count? A low red blood cell (RBC) count can cause a variety of symptoms and health complications. When a person has a lower red blood count than is normal, their body has to work harder to get enough oxygen to the cells. What does it mean when your red blood cells are low?Ī low red blood count, or anemia, can cause feelings of fatigue and weakness. What causes low red blood cell count hemoglobin and hematocrit? Anemia is a common side effect in patients with cancer. Hemoglobin is the part of the red blood cell (RBC) that carries oxygen to all the cells in your body. This means your blood has lower than normal hemoglobin (Hgb) levels. When you don’t have enough healthy red blood cells, you have a condition called anemia. What does low red blood cell count and low hemoglobin mean?
