Iron deficiency is not a disease to have medicine. But it is definitely a condition to grab your attention to seek special attention.

It arises when the body’s iron reserves and circulating iron levels are insufficient. This can culminate in iron deficiency anemia, characterized by a reduced capacity to transport oxygen due to inadequate red blood cell production. Iron deficiency occurs when the body’s demand for this essential mineral exceeds its supply. Individuals at heightened risk include women, those with inflammatory bowel disease, and patients with chronic heart failure or chronic kidney disease.

In simple words: 

Imagine your body is a car. Iron is like the special fuel that helps your car – or your body – go zoom! It helps your blood carry oxygen to all the parts of your body, like your muscles, brain, and even your skin. When you don’t have enough iron, it’s like your car is running on fumes. You might feel tired all the time, like you want to sleep all day. Your skin might look a little pale, and you might not have as much energy to play.

Iron supply must match bodily demands.

Effecting physically

  1. Fatigue – Reduced iron levels impair the body’s ability to transport oxygen effectively, resulting in decreased energy production and ultimately, fatigue. 
  2. Mental fatigue – Iron deficiency can significantly impact mental function beyond just physical fatigue. Iron deficiency can contribute to feelings of irritability, anxiety, and even depression. When iron levels are low, neurotransmitter production can be disrupted
  3. Giddiness – When iron levels are low, the body produces fewer red blood cells, resulting in reduced oxygen delivery to the brain. 2 This oxygen deprivation can cause dizziness, lightheadedness, and even fainting.
  4. Cold intolerance – When  iron levels are low, oxygen delivery to tissues is reduced, impacting the body’s ability to regulate temperature effectively. This can result in feeling cold, especially in the extremities like hands and feet, even in warm environments.
  5. Restless leg syndrome – When  iron levels are low, particularly in specific areas of the brain, can disrupt the balance of neurotransmitters, including dopamine, which plays a crucial role in movement control. This imbalance can trigger the uncomfortable sensations and urge to move associated with RLS.
  6. Craving unusual foodstuffs, including chewing ice -We hypothesize that chewing ice triggers vascular changes that lead to preferential or increased perfusion of the brain. This would result in increased alertness and processing speed in anemic patients, but not in healthy controls who are already at ceiling, and would explain why anemic individuals crave ice. Can lead to Poisoning, Gastrointestinal Problems, Dental Problems, anxiety, social isolation, and low self-esteem
  7. Mouth ulcers and cracks – Iron deficiency can affect the health of oral tissues. Reduced oxygen delivery due to iron deficiency may contribute to changes in the oral mucosa (the lining of the mouth), making it more prone to ulceration and cracks.
  8. Bruising easily – In severe cases of iron deficiency anemia, the body’s ability to produce platelets may be impaired. Platelets are essential for blood clotting, and a low platelet count (thrombocytopenia) can increase the risk of easy bruising.
  9. Weakened Immunity – Iron deficiency weakens the immune system, making you more susceptible to infections. 1 Iron plays a vital role in the production and function of immune cells, which are responsible for fighting off infections. 2 When iron levels are low, these cells cannot function properly, leaving your body more vulnerable to illness.
  10. Reduced Cognitive Development –  Insufficient iron can impair cognitive functions such as attention, memory, learning, and problem-solving.
  11. Reduced Breast milk – Iron is essential for various bodily functions, including the production and maintenance of bodily tissues. In the context of breastfeeding, iron plays a role in supporting the healthy function of the mammary glands, which are responsible for milk production.
