Iron plays a key role in the metabolism of monoamines in the brain thus iron deficiency leads to symptoms such as apathy, drowsiness, irritability and lack of attention occur due to impaired monoamine oxidase activity7.
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.
Your body needs iron to produce enough of a component in red blood cells that makes it possible for them to carry oxygen (hemoglobin). Hence, iron deficiency may make you feel lethargic and breathless. In fact, your body becomes unable to produce sleep hormones without iron.
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.
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.
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.
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.
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.
Tea, coffee and wine contain tannins that reduce iron absorption by binding to the iron and carrying it out of the body. Phytates and fibres found in wholegrains such as bran can reduce the absorption of iron and other minerals.

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.
– It usually takes 2 to 3 weeks of taking regular iron supplements before your symptoms start to improve. – You may need to keep taking iron for several months to build up your iron reserves and keep your anemia from returning. Take your pills for as long as your doctor recommends, even if your symptoms have improved.
Brain iron deficiency is associated with disruption of neurophysiological mechanisms that, within a social context that does not provide regular stimuli, compromises motor and cognitive development (e.g., impaired motor sequencing and bi-manual coordination, poor executive function, attention, and memory).
What has been determined is that stress can lead to nutritional deficiencies, which may contribute to the development of iron deficiency anemia. A person with anemia is likely to feel emotional stress over their symptoms. Unfortunately, this can worsen anemic symptoms.
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.
The short answer is yes. This can be for both medical and lifestyle reasons. For example, if you are trying to improve your iron intake through diet and the consumption of iron-rich foods, this is likely to lead to an increase in healthy meals, which can contribute to weight loss.
The range of normal ferritin in most laboratories is 30 ng/mL to 300 ng/mL, and the mean is 49 ng/mL in women. The National Health and Nutrition Examination Survey describes iron deficiency in women as a low concentration of ferritin (<12 ng/mL). Diagnosis prompts consideration of the cause of IDA (usually, bleeding).
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.
