HGB is short for hemoglobin, which is found in red blood cells (erythrocytes). Hemoglobin is an oxygen-carrying protein pigment that transports oxygen to cells throughout the body. Low hemoglobin levels, Hemoglobin is a condition in which the level of hemoglobin in the blood is lower than normal. Hemoglobin levels can be determined with a blood test that measures the amount of hemoglobin in the blood.
Low hemoglobin levels can be caused by a variety of factors. Some possible causes include:
• Iron deficiency: Iron is important for the production of red blood cells. When the body lacks iron, new red blood cells cannot be produced, and existing red blood cells carry less hemoglobin than normal.
Vitamin deficiency: Vitamin B12 and folic acid are important for the production of red blood cells. When one of these vitamins is deficient, red blood cell production slows down, and existing cells carry less hemoglobin than normal.
• Blood loss: Bleeding can cause hemoglobin levels to drop. Especially in cases of chronic blood loss, red blood cell production may not be fast enough, leading to low hemoglobin levels.
• Chronic diseases: Some chronic diseases, such as kidney disease or cancer, can affect the production of red blood cells and hemoglobin levels.
Low hemoglobin levels Symptoms include fatigue, pallor, shortness of breath, heart palpitations, dizziness and pale skin.
Low hemoglobin levels In people with this condition, the underlying cause must be treated. Treatment for this condition can vary depending on the cause and may include iron supplements, vitamin supplements, blood transfusions, and, in some cases, medications.
