Iron deficiency can lead to a range of health issues from heart failure to depression. Recognising the early signs can prevent many health complications.

Do you feel tired all day even with sufficient rest or experiencing shortness of breath? You may be deficient in an important mineral required for body functions – iron. These changes can be gradual or rapid, making you feel grumpy, weak or tired, and cause issues in concentration. Iron is involved in important body functions including production of haemoglobin, the molecule in your blood that carries oxygen and helps maintain healthy cells, skin, hair, and nails.

Iron deficiency is common in pregnant women, those who experience heavy periods, people with GI disorders, or those who do not eat an iron-rich diet. Symptoms of low iron can be visible in pale skin and nails, unexplained weakness, fatigue or lack of energy, shortness of breath, headache among others.

“Iron deficiency is a widespread nutritional insufficiency affecting individuals worldwide, with significant implications for health. Recognizing the key signs of iron deficiency is essential for early detection and prompt intervention to prevent further health complications,” says Dr Aditya S Chowti, Senior consultant, Internal Medicine, Fortis Hospital, Cunningham Road, Bengaluru.

SIGNS AND SYMPTOMS OF IRON DEFICIENCY

Fatigue and weakness are among the most prevalent indicators of iron deficiency. Individuals may experience persistent feelings of tiredness and weakness, even after obtaining adequate rest. This fatigue stems from reduced haemoglobin levels, which impairs the blood’s ability to transport oxygen efficiently throughout the body.

This is another prominent sign of iron deficiency. A pallid complexion, particularly noticeable in facial features, lips, and nail beds, may indicate decreased haemoglobin levels, resulting in diminished oxygenation of tissues
