Specifically, iron plays an important role in how your body makes the neurotransmitters called serotonin, dopamine and norepinephrine – all of them important in mental health. Research suggests a connection between low iron levels and symptoms of depression, anxiety, and schizophrenia, Levin and Gattari write.
In the brain, iron is bound to ferritin, the levels of which are decreased by iron deficiency and increased by iron supplementation. Low ferritin levels in childhood have been reported to affect the development of the central nervous system, leading to mental retardation and behavioral disorders.
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.
When your body isn't getting enough oxygenation due to a lack of iron, you may find it hard to maintain focus and carry out your daily tasks. In addition, you may experience mood swings and irritability. Over time, in some cases, it may cause anxiety and depression. So, all these problems are interrelated.”
Iron deficiency anemia and depression
According to a 2020 study , iron deficiency anemia can increase a person's risk of depression. Iron deficiency can cause low levels of serotonin, an important neurotransmitter and mood stabilizer.
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).
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're constantly craving ice. Craving ice is a specific form of pica called pagophagia, according to a series of case reports published in the the journal Pediatric Hematology and Oncology, and it's one of the most common symptoms of severe iron deficiency.
People lacking enough iron in their blood often feel sluggish, weak, and unable to focus. Though fatigue can be the sign of numerous conditions, if it does not go away with adequate rest, consider having your iron levels checked.
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.
When will I start to feel better? It may take one to four weeks (after you start your iron supplement) before you start to feel better.
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.

Iron deficiency is considered to be a physical condition, but there is a strong association between iron deficiency and struggling mental health. Iron is a vital element that influences many other bodily functions.
Children can appear unmotivated, apathetic and less physically fit. Anemic children have difficulty with tests and are more disruptive than their classmates. A child with nutrient deficiencies may be irritable, aggressive, disagreeable, or sad and withdrawn.
"If you actually ask women who have iron deficiency what their symptoms are, fatigue and tiredness is there but right at the top of the list is brain fog and that's what women described — it's the inability to think clearly," says Professor Toby Richards.
You also may feel grumpy, have headaches, and have trouble concentrating. Most people begin to feel normal after a few weeks of taking iron pills. But you need to take the pills for several months to build up the iron supply in your body.
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.
Untreated anemia can cause a rapid or irregular heartbeat. It also puts a lot of stress on your heart. Anemia lowers your red blood cell count. When you don't have enough red blood cells, your heart has to pump a lot more blood to make sure that enough oxygen gets to all your organs.
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 you think you may have severe anemia, it is essential that you call your physician, go to the emergency room for evaluation, or call 911 to get help. One treatment that may help those with severe anemia could be hyperbaric oxygen therapy (HBOT).
While there's little scientific evidence backing this claim up, weight gain from iron pills does happen 6. One study found that individuals with iron deficiency anemia complained of weight gain during their treatment, even though oral preparations of iron aren't known to cause weight gain as a side effect.
People with symptoms of iron deficiency may feel more energetic and less tired during exercise once iron pills start working. Once the iron level is restored and hemoglobin levels rise, symptoms of iron deficiency resolve.
The best way to determine whether iron pills are working is to check your ferritin levels via a blood test. A ferritin test will show how much iron your body stores.
