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.
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. Iron deficiency can cause you to have unusual cravings for non-food items such as ice, dirt or paper.
The body uses its stored iron in the muscles, liver, spleen, and bone marrow. But when levels of iron stored in the body become low, iron deficiency anemia sets in. Red blood cells become smaller and contain less hemoglobin. As a result, blood carries less oxygen from the lungs throughout the body.
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.
A large 2020 study in BMC Psychiatry found that people with iron deficiency anemia had a significantly higher incidence and risk of anxiety disorders, depression, sleep disorder, and psychotic disorders.
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.
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.
Inhibitors of iron absorption include phytate, which is a compound found in plant-based diets that demonstrate a dose-dependent effect on iron absorption. Polyphenols are found in black and herbal tea, coffee, wine, legumes, cereals, fruit, and vegetables and have been demonstrated to inhibit iron absorption.
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.
If left untreated, iron-deficiency anemia can cause serious health problems. Having too little oxygen in the body can damage organs. With anemia, the heart must work harder to make up for the lack of red blood cells or hemoglobin. This extra work can harm the heart.
During stage 2, erythropoiesis is impaired. Although the transferrin level is increased, the serum iron level decreases; transferrin saturation decreases. Erythropoiesis is impaired when serum iron falls to < 50 mcg/dL (< 9 micromol/L) and transferrin saturation to < 16%.
If you suspect you might have an anemic disorder, check yourself for the following symptoms and call your doctor for further advice. A sudden lack of energy and chronic fatigue are warning signs that you might be lacking enough iron.
Iron deficiency is commonly misdiagnosed. The usual error is misinterpretation of the laboratory features of the anaemia of chronic disease. The serum iron is low, but the iron binding capacity is normal and ferritin is normal or high. There are problems and exceptions involved in interpretation of iron indices.
Extreme fatigue and exhaustion “Fatigue is one of the most common signs of iron deficiency because it means your body is having trouble carrying the oxygen to your cells so it's affecting your energy levels,” Thayer says. People lacking enough iron in their blood often feel sluggish, weak, and unable to focus.
Having an iron-deficiency may not cause insomnia or sleep problems but it can make you feel exhausted and overtired, which in turn may hinder your efforts to fall asleep in the first place!
Yes. Low iron causes low energy, which may result in burning fewer calories and causing you to keep reducing your caloric intake to lose weight.
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.
Iron deficiency anemia arises when the balance of iron intake, iron stores, and the body's loss of iron are insufficient to fully support production of erythrocytes. Iron deficiency anemia rarely causes death, but the impact on human health is significant.
Furthermore, headache and muscle and joint pain associated with iron deficiency are repeatedly considered migraine and fibromyalgia syndrome, respectively 3, 19. The multitude of symptoms is commonly associated low ferritin concentration without anemia 1, 17, 20, 21, 22.
Fatigue — feeling too tired to manage your activities — is the most noticeable anemia symptom. Other symptoms may include: Shortness of breath (dyspnea): This is the feeling you can't catch your breath or take a deep breath. Dizziness: This is feeling lightheaded or unsteady on your feet.
