Iron is an essential nutrient that plays a vital role in the proper functioning of the human body. It is necessary for the production of haemoglobin, which carries oxygen from the lungs to the body's tissues. Iron also plays a critical role in the synthesis of neurotransmitters and the maintenance of the immune system. However, when the body does not have enough iron, it can lead to a condition called iron deficiency.
Iron deficiency is one of the most common nutrient deficiencies worldwide, affecting an estimated 1.6 billion people. It is particularly prevalent in developing countries, where diets may be low in iron, and parasitic infections can exacerbate iron loss. In developed countries, iron deficiency is most common in women, particularly pregnant and lactating women, and children under the age of five.
Signs Of Iron Deficiency
The symptoms of iron deficiency can range from mild to severe, and it can be challenging to diagnose without a blood test. However, there are several signs that can indicate an iron deficiency, including:
1. Fatigue and Weakness
Feeling tired and weak is a common symptom of iron deficiency. This occurs because the body cannot produce enough haemoglobin to transport oxygen to the body's tissues. As a result, the body's cells do not receive enough oxygen, leading to feelings of exhaustion.

2. Pale Skin
Iron is responsible for giving blood its red colour, so when there is not enough iron in the body, the skin can appear pale or even yellowish. This is because there is less haemoglobin available to provide colour to the skin.
3. Shortness of Breath
When the body is not getting enough oxygen, it can lead to shortness of breath, even during mild physical activity. This occurs because the body is working harder to compensate for the lack of oxygen.
4. Headaches and Dizziness
Iron deficiency can also cause headaches and dizziness. This is because the brain is not receiving enough oxygen, leading to decreased cognitive function.
5. Restless Leg Syndrome
Restless leg syndrome is a neurological disorder characterised by an irresistible urge to move the legs. While the exact cause of restless leg syndrome is not known, iron deficiency is a known risk factor.
6. Brittle Nails
Iron is essential for healthy nail growth, and a lack of iron can cause nails to become brittle and break easily.

7. Pica
Pica is a condition characterised by cravings for non-food items, such as ice, dirt, or clay. While the exact cause of pica is not known, it is often associated with iron deficiency.
8. Difficulty Swallowing
Iron deficiency can cause inflammation and swelling of the tongue and throat, making it difficult to swallow.
9. Hair Loss
Iron is essential for healthy hair growth, and a lack of iron can cause hair to become thin, brittle, and fall out.
10. Increased Susceptibility to Infections
Iron is necessary for the proper functioning of the immune system, and a lack of iron can make individuals more susceptible to infections.
Iron deficiency can have serious consequences if left untreated, including anaemia, impaired cognitive function, and increased susceptibility to infections. If you are experiencing any of the above symptoms, it is important to see a healthcare provider who can perform a blood test to determine if you have an iron deficiency.
Iron deficiency is a common condition that can have serious consequences if left untreated. While the symptoms of iron deficiency can be vague and difficult to diagnose, there are several signs, including fatigue, pale skin, shortness of breath, headaches, and dizziness, that can indicate a deficiency. If you suspect you have an iron deficiency, it is essential to seek medical attention to determine the underlying cause and receive appropriate treatment.
