Grading of anemia, according to the National Cancer Institute, is as follows: 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.
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.
A severe low hemoglobin level for men is 13.5 gm/dL or lower. For women, a severe low hemoglobin level is 12 gm/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.
Fatigue. Tiring easily, and waking up tired even after a good night's sleep, are common and potentially serious symptoms of anemia. This is due to reduced and compromised red blood cells that naturally cannot carry the required levels of oxygen to the organs – which, in turn, cannot function efficiently.
Several treatments can be used to treat anemia. Iron supplements, also called iron pills or oral iron, help increase the iron in your body. This is the most common treatment for iron-deficiency anemia. It often takes three to six months to restore your iron levels.
Low red blood cells – hemoglobin level less than 120 g/L (grams per litre).
Following treatment, most people go on to live normal, healthy lives. However, anemia can have lasting, or life-threatening, effects. These are more common if the condition is chronic, severe, or left untreated.
Iron deficiency anemia can produce symptoms such as fatigue that impact your daily life. It can increase your risk of anxiety and depression. You can use strategies to manage the fatigue, including changes to sleep, diet, and activity. You may need help and support from family, friends, and medical professionals.
“Anemia cannot cause leukemia but could be a sign of bone marrow that's not producing enough red blood cells,” Dr. Wetmore explained. “This requires an investigation (lab tests) into the cause of low numbers of red blood cells.”
You may also find that low iron causes weight gain. There are a couple of reasons for this; firstly, your energy levels are low and so your exercise levels reduce; secondly, iron is essential for thyroid function, and an underactive thyroid will lead to weight gain.
Normally, it may take from a week to a month after you start your iron supplement before you start to feel better. Continue to watch your symptoms and take note of side effects that might be caused by the supplements. If you have any questions or concerns, talk to your healthcare provider.
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.
Severe iron-deficiency anemia may require a blood transfusion, iron injections, or intravenous (IV) iron therapy. Treatment may need to be done in a hospital.
Iron. Your body needs iron to make hemoglobin. Your body can more easily absorb iron from meats than from vegetables or other foods. To treat your anemia, your doctor may suggest eating more meat—especially red meat (such as beef or liver), as well as chicken, turkey, pork, fish, and shellfish.
What to do if you have anemia. If your red blood cell count is low, you should: Save your energy. Rest when you are tired.
A lack of iron in your body can lead to several problems, including sleep issues. It can disrupt your sleep cycle and lead to problems like periodic limb movement disorder and insomnia. A lot of people tend to overlook the signs of iron deficiency or anemia, but it is vital to keep its level in check.
If you're feeling tired or weak, having trouble sleeping and are unable to tolerate even moderate exercise, anemia could be the culprit. Anemia develops when there aren't enough healthy red blood cells to carry oxygen through your body.
Iron is a mineral that's part of hemoglobin, the protein in red blood cells that transports oxygen from the lungs and throughout the body. If your body doesn't have enough iron, it won't get enough oxygen, and your cells (which are powered by oxygen) won't be able to function efficiently.
