7 complications your body can show due to iron deficiency
Iron deficiency, a common nutritional issue, can silently impact various bodily functions. Without enough iron, your body struggles to produce adequate haemoglobin, leading to noticeable health complications that affect energy, immunity, and overall well-being over time.
Low iron levels reduce oxygen transport in the blood, making muscles and tissues energy-deprived. This results in constant tiredness, weakness, and difficulty concentrating, even after rest or sleep, affecting daily productivity and motivation.
Iron helps produce haemoglobin, which gives blood its red colour. When levels drop, skin can appear noticeably pale or washed out, especially on the face, inside lips, and lower eyelids, indicating reduced blood circulation.
Insufficient iron limits oxygen delivery to muscles and tissues, making even simple activities like climbing stairs or walking difficult. You may experience breathlessness or a racing heartbeat without exertion, signaling oxygen deficiency in the body.
Lack of oxygen in the brain due to low hemoglobin levels can lead to persistent headaches or frequent dizziness This occurs as blood vessels swell in response, causing pressure and pain around the forehead or temples.
Iron deficiency weakens keratin production, resulting in dry, fragile nails that break easily and excessive hair shedding. Hair may appear thin, dull, or fall out in patches, indicating poor nourishment and blood supply to follicles
A tingling, crawling sensation in the legs—especially at night—is a sign of iron deficiency. It disrupts sleep and causes uncomfortable urges to move the legs, often linked to reduced dopamine function in the brain.
Iron supports immune cell production and function. When deficient, the body struggles to fight infections, leading to frequent colds, sore throats, or slow-healing wounds, reflecting compromised immunity and increased vulnerability to illness.
