why hgb count is low?

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 counts can be contributed to sepsis, autoimmune disorders, lymphoma or conditions that affect bone marrow function. The test is nearly always ordered as part of a complete blood count, or CBC.

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.

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.
847486
Low red blood cell production. This occurs if the baby doesn't get enough iron (a nutrient that helps build red blood cells). Normally, the baby's body stores iron during the last months of pregnancy.

If the number of RBCs is lower than normal, it may be caused by: anemia. bone marrow failure. erythropoietin deficiency, which is the primary cause of anemia in patients with chronic kidney disease.

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 ).

A low red blood count, or anemia, can cause feelings of fatigue and weakness. 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. A low red blood cell (RBC) count can cause a variety of symptoms and health complications.
320049
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.

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.
753508
Low hemoglobin levels Iron-deficiency anemia is the most common type. This form of anemia occurs when a person does not have enough iron in their body, and it cannot make the hemoglobin it needs. Anemia is usually caused by blood loss, but can also be due to poor absorption of iron.
354601
Anemia is caused by lack of Hemoglobin. Iron Deficiency is caused by lack of Iron. Iron Deficiency with Anemia is caused by both a lack of Iron AND a lack of Hemoglobin.
924622
Many symptoms of anemia are due to a general lack of oxygen that is available to the cells. Your symptoms may also be caused by low blood pressure (hypotension), which is due to reduced blood volume. Blood volume will be low if anemia develops quickly, as in blood loss from hemorrhage.
888976
Anemia in CHF may be due to chronic disease, bone marrow depression from excessive cytokine production,4 malnutrition, concomitant renal disease, and/or drug therapy. A reduced hematocrit can result not only from a reduced red blood cell (RBC) volume but also from an increased plasma volume.
589289
The most common cause of low MCHC is anemia. Hypochromic microcytic anemia commonly results in low MCHC. This condition means your red blood cells are smaller than usual and have a decreased level of hemoglobin.
1023897
White blood cell count (WBC) 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. A high WBC count may result from an infection or leukemia.
827791
If your body doesn't have enough iron, it cannot produce enough healthy oxygen-carrying red blood cells. Iron deficiency can cause anemia, which means you have too little hemoglobin. Women in their childbearing years are at higher risk for iron deficiency because of the loss of blood during menstruation.
