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.
However, left untreated, iron deficiency anemia can become severe and lead to health problems, including the following: Heart problems. Iron deficiency anemia may lead to a rapid or irregular heartbeat. Your heart must pump more blood to compensate for the lack of oxygen carried in your blood when you're anemic.
Untreated anemia can exacerbate underlying cardiovascular issues. Extreme cases can lead to an enlarged heart, heart murmurs, or even heart failure.
Left untreated, however, iron-deficiency anemia can make you feel tired and weak. You may notice pale skin and cold hands and feet. Iron-deficiency anemia can also cause you to feel dizzy or lightheaded. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath.
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.
Call Your Doctor About Anemia If:
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.
Hemoglobin less than 6.5 g/dL is life-threatening and can cause death.
As the anemia gets worse, symptoms may include: Brittle nails. Blue color to the whites of the eye. Desire to eat ice or other non-food things (pica)
If you have anemia, your body does not get enough oxygen-rich blood. The lack of oxygen can make you feel tired or weak. You may also have shortness of breath, dizziness, headaches, or an irregular heartbeat.
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 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.
Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body. Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.
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.
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.
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.
Undiagnosed or untreated iron-deficiency anemia may cause serious complications such as fatigue, headaches, restless legs syndrome, heart problems, pregnancy complications, and developmental delays in children. Iron-deficiency anemia can also make other chronic conditions worse or cause their treatments to work poorly.
“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.”
Foods to avoid
milk and some dairy products. foods that contain tannins, such as grapes, corn, and sorghum. foods that contain phytates or phytic acid, such as brown rice and whole-grain wheat products. foods that contain oxalic acid, such as peanuts, parsley, and chocolate.
One of the best ways to manage anemia-related fatigue is to try and get sufficient sleep. However, you will want to avoid sleeping too much because that will add to fatigue. Instead, aim to get seven to nine hours of sleep every night. Naps are fine but limit yourself to one short 20- to 30-minute nap a day.
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.
On the basis of RBC transfusion guidelines, severe anemia was defined as a hemoglobin level less than 7 g/dL (22). We defined admission hemoglobin as the lowest hemoglobin level within 72 hours before hospital entry or the most recent hemoglobin level within 30 days before an elective admission.
Eye symptoms of low iron can include a pale coloring of the inside of the lower eyelids. In moderate or severe cases of iron deficiency anemia, the inside layer of the lower eyelid is very pale pink or yellow instead of red. Rather than low iron, one common cause of blurry vision is dry eye.
With treatment, most people recover from iron-deficiency anemia in 2 to 3 months. You may need to take iron supplements for several months longer, though, to build up your reserves of iron.
