Mild: Hemoglobin 10.0 g/dL to lower limit of normal. Moderate: Hemoglobin 8.0 to 10.0 g/dL. Severe: Hemoglobin 6.5 to 7.9 g/dL[1] Life-threatening: Hemoglobin less than 6.5 g/dL.
You should call 911 or go to the emergency room if you are having severe symptoms or any chest pain, shortness of breath, or loss of consciousness. Left untreated, anemia can cause many health problems, such as: Severe fatigue. Severe anemia can make you so tired that you can't complete everyday tasks.
What hemoglobin levels are considered severe or dangerously low? A hemoglobin level of less than 5.0 grams per deciliter (g/dl) is dangerous and could lead to heart failure or death. A normal hemoglobin level is 13.2–16.6 grams per deciliter (g/dL) for males and 11.6–15 g/dL for females.
Extra blood units are not helpful.
But 7 to 8 g/dL is a safe level. Your doctor should use just enough blood to get to this level. Often, one unit of blood is enough. Some doctors believe that hospital patients who fall below 10 g/dL should get a blood transfusion.
Anemia is further categorized into five grades based on the Hb level, as follows: Grade 0, normal Hb level; grade 1 (mild anemia), 100 g/l, normal level; grade 2 (moderate anemia), 80-100 g/l; grade 3 (severe anemia), 65-80 g/l; and grade 4 (life-threatening anemia), <65 g/l.
Full blood examination
The World Health Organization (WHO) defines anaemia as a Hb level below 130 g/L in men, 120 g/L in non-pregnant women and 110 g/L in pregnant women and preschool children.
Low red blood cells – hemoglobin level less than 120 g/L (grams per litre). Low iron level – ferritin under 30 μg/L (micrograms per litre), or under 200 μg/L with iron saturation less than 20%.
This may be needed when: there's blood loss due to bleeding. there's a failure to make blood which results in anaemia. inherited conditions mean the production of blood is faulty.
Mild: Hemoglobin 10.0 g/dL to lower limit of normal. Moderate: Hemoglobin 8.0 to 10.0 g/dL. Severe: Hemoglobin 6.5 to 7.9 g/dL[1] Life-threatening: Hemoglobin less than 6.5 g/dL.
Severe iron deficiency anaemia may increase your risk of developing complications that affect the heart or lungs, such as an abnormally fast heartbeat (tachycardia) or heart failure, where your heart is unable to pump enough blood around your body at the right pressure.
WHO defines anaemia in children aged under 5 years and pregnant women as a haemoglobin concentration <110 g/L at sea level, and anaemia in non-pregnant women as a haemoglobin concentration <120 g/L.
Persistent fatigue, breathlessness, rapid heart rate, pale skin, or any other symptoms of anemia; seek emergency care for any trouble breathing or change in your heart beat.
When anaemia is severe your GP can refer you to the Anaemia clinic at the hospital because you do not have enough haemoglobin in your blood which can lead to symptoms such as fatigue/ tiredness.
But as the anemia gets worse, you may develop a blue color to the whites of your eyes, light-headedness when you go to stand up and you may look pale or experience shortness of breath. To find out if you've got iron-deficiency anemia. See your doctor; your doctor will start with a Complete Blood Count or CBC test.
This is an iron sucrose which cannot be given in a large dose. Rather, the formula is given in a series of small doses each taking about half an hour and repeated over a period of days and weeks. This is an iron dextran, which can be given in a single large dose over a number of hours and requires hospital admission.
For all types of anemia, particularly iron and vitamin deficiency anemia, symptoms such as exhaustion and lack of energy can make it difficult to exercise. A lack of physical activity can result in weight gain.
Patients who receive IV iron usually do so because they cannot take oral iron. These include the following: Patients who are bleeding in the gastrointestinal (GI) tract (the gut) and need to replace iron quickly. (IV iron is absorbed by the body more rapidly than oral iron.)
Intravenous iron is superior to blood transfusion in replenishing pre-pregnancy iron stores.
How long does it take to recover from a blood transfusion? After your transfusion, your healthcare provider will recommend that you rest for 24 to 48 hours. You'll also need to call and schedule a follow-up visit with your healthcare provider.
Blood components must be transfused within 4 hours of issue. If the transfusion is interrupted for any reason, administration must be discontinued after 4 hours even if the transfusion is not complete.
The last stage is iron deficiency anemia. It is characterized by a low hemoglobin concentration with small (microcytic), pale (hypochromic) RBCs. Symptoms include fatigue upon exertion, weakness, headaches, apathy, pallor, poor resistance to cold temperatures, low physical work capacity, and poor immune function.
About 25% of iron deficient subjects have a serum ferritin in the range of 16–30 µg/l. some argue that levels below 40–45 µg/l represent a state of iron shortage and should be actively treated.
