An iron deficiency headache often feels like a dull, persistent ache or throbbing pressure, sometimes across the forehead or behind the eyes, caused by reduced oxygen to the brain, leading to widening blood vessels. It can also manifest as dizziness, lightheadedness, or be severe enough to mimic migraines, with worsened pain from movement, poor response to painkillers, and accompanying fatigue, pale skin, or cold extremities.
The type of headache a person experiences as a result of iron-deficiency anemia can vary. Some people will experience a dull aching sensation throughout their head. They may also feel lightheaded or dizzy. A migraine episode will feel different.
Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath. Or it can cause you to crave non-food items like ice, dirt or paper. These are all signs of iron-deficiency anemia. The good news is that treatment can help iron-deficiency anemia.
Dizziness or lightheadedness. Headache. A lightening of the skin or yellowing of the skin and eyes. Shortness of breath.
Unlike traditional tinnitus, which manifests as constant ringing, pulsatile tinnitus is frequently linked to blood flow abnormalities. One lesser-known but significant cause is anemia, particularly iron deficiency anemia, which can disrupt normal blood circulation.
Symptoms of iron-deficiency anemia may include:
For proper hearing, your ears need an oxygen-rich blood supply. A growing body of evidence is indicating that anemia and hearing loss are linked—particularly for a common type of anemia linked to low levels of iron.
Iron supplements are key for iron-deficiency anemia. They help reduce fatigue and headaches. Vitamin B2 (riboflavin) and magnesium also help with headaches. Vitamin B2 helps cells make energy, and magnesium controls blood vessel constriction and brain chemicals.
Possibly. The term "pica" describes craving and chewing substances that have no nutritional value — such as ice, clay, soil or paper. Craving and chewing ice, known as pagophagia, is often associated with iron deficiency, with or without anemia, although the reason is unclear.
It is important to emphasize that in patients with iron deficiency anemia, iron will need to be given for a prolonged period of time. It generally takes 2–3 months for the hemoglobin level to return to normal level.
Iron is depleted by blood loss (heavy periods, bleeding ulcers, surgery), increased demand (pregnancy, growth spurts, intense exercise), poor dietary intake, and conditions that hinder iron absorption (celiac disease, gastric bypass, some medications, or certain foods/drinks like tea/coffee/dairy with meals). Exercise can cause loss through sweating, red blood cell damage (hemolysis), and increased needs, while poor absorption is a major factor, even with good intake.
Iron deficiency (ID) has received increasing attention in disorders affecting sleep and wake behaviors. ID has been shown to be associated not only with RLS/PLMs [14] and arousal disorders like parasomnias [15], but also in sleep disordered breathing (SDB) [16], RSD, and in pediatric ADHD [17].
While symptoms such as fatigue and pale skin are widely recognized, anemia can also contribute to swelling of the legs and feet, especially in moderate to severe cases.
“Low iron levels can contribute to migraine by impairing the body's ability to transport oxygen efficiently, leading to reduced oxygen in the brain and triggering headaches,” says Natbony. According to human studies, low oxygen can trigger migraine attacks.
Sudden daily headaches can start because of things like stress, poor sleep, certain foods, or medical issues. They may also be linked to medication overuse, hormonal changes, or conditions like migraines, tension headaches, or sinus problems, which a healthcare provider can help diagnose.
For quick iron, focus on easily absorbed heme iron from red meat, poultry, and seafood (beef, chicken, oysters, tuna) or plant-based non-heme iron from spinach, lentils, beans, tofu, fortified cereals, and pumpkin seeds, pairing plant sources with Vitamin C (citrus, tomatoes, peppers) for better absorption.
Low iron can leave us feeling fatigued and weak and we can crave quick energy as a result. Magnesium regulates glucose and insulin levels, as well as the neurotransmitter dopamine. A deficiency will cause intense sugar cravings, especially for chocolate or something sweet.
Eyes and vision can be negatively impacted by iron deficiency anemia, leading to vision loss in extremely rare cases. When caught early, the condition is treatable with a daily intake of iron supplements, eating a healthy diet, and maintaining a healthy lifestyle.
When your brain doesn't get enough oxygen from the blood, it can trigger headaches. The headaches may be dull and constant or come and go. Shortness of Breath: You may notice yourself feeling winded or short of breath easily with anemia.
Anemia due to iron deficiency is a highly prevalent medical condition in women and children. Iron deficiency presents with fatigue, low mood, anxiety, restlessness, palpitations, and headache. Poor nutritional intake can be the reason of iron deficiency in underprivileged populations.
B vitamins and headaches
Vitamin B12 deficiency can lead to anemia (low red blood cell count). And this can indirectly cause headaches. There's some evidence that vitamin B1 and vitamin B12 deficiencies may be linked to migraines. Severe vitamin B3 and vitamin B5 deficiencies can cause headaches.
Less common symptoms of iron deficiency anaemia (that are not usually connected to pregnancy) include: hearing ringing, buzzing or hissing noises inside your head (tinnitus)
In conclusion, we found that, compared to nonanemic individuals, those who were anemic (non-iron-deficient) had more severe insomnia and a greater likelihood of having two or more insomnia symptoms.
Diabetes can contribute to anemia through reducing absorption of iron, gastrointestinal bleeding and through diabetic complications that cause anemia (1-3).
