Many people wake up after a full night's sleep yet feel drained throughout the day. While stress or poor sleep are often blamed, low iron stores can also cause persistent fatigue. Iron is vital for producing hemoglobin, the molecule that transports oxygen in the blood. When iron is insufficient, organs and muscles may receive less oxygen, producing weakness, tiredness and lightheadedness.
Dr Kunal Sood, an anaesthesiologist and pain medicine specialist, says persistent tiredness is a common early clue of iron shortage. He explains, "Iron is needed to make haemoglobin. If iron levels fall, the body cannot make enough oxygen-carrying red blood cells, which leads to fatigue, weakness and occasional dizziness."
Certain groups face higher risk of low iron, including women with heavy menstrual bleeding, pregnant people, those following vegetarian diets and patients with some medical conditions. If left untreated, iron deficiency can progress to iron deficiency anaemia and bring additional signs such as pale skin, cold extremities, breathlessness and unusual cravings like chewing ice.
The condition is often correctable through diet. Dr Sood advises adding iron-rich foods such as spinach, red meat, lentils, beans and fortified cereals to daily meals. Combining these with vitamin C sources — for example oranges, tomatoes or bell peppers — enhances iron absorption.
When dietary changes are insufficient, iron supplements may be prescribed, but a clinician should approve any supplementation. Dr Sood stresses that people experiencing prolonged fatigue should have their iron levels checked with a simple blood test so treatment can begin if needed.
Fatigue is widespread but should not be dismissed. Paying attention to persistent low energy, increasing iron intake where appropriate, getting adequate rest and consulting a doctor can prevent longer-term effects and restore everyday vitality.
