Iron Deficiency in the Body: 10 Symptoms You Can't Ignore.

According to ТСН: Iron deficiency in the body often occurs gradually, so its symptoms may go unnoticed or be explained by other causes. However, iron deficiency is the leading cause of iron deficiency anemia—the most common form of anemia in the world. This leads to a reduced ability of the blood to carry oxygen, causing organs and tissues to suffer from its lack.

Symptoms of Iron Deficiency

Iron is essential for the production of hemoglobin—a protein in red blood cells that carries oxygen from the lungs to all cells of the body. When iron levels drop, the production of hemoglobin slows down. As a result, muscles, the brain, and internal organs receive less oxygen, and the heart is forced to work harder to compensate.

Among the most common symptoms are persistent fatigue that does not disappear even after rest. This condition arises from tissue hypoxia and is one of the first signs of anemia. Fatigue is often associated with stress, causing iron deficiency to go unnoticed for an extended period.

Another characteristic sign is pale skin. A drop in hemoglobin levels makes blood less saturated with red color, which is noticeable in appearance. This can especially be seen on the inner surface of the lower eyelids or in the folds of the palms. Medical examinations show that these areas often help suspect anemia, although a definitive diagnosis is confirmed only by a blood test.

With iron deficiency, shortness of breath may occur even during usual physical activities such as walking or climbing stairs. The body tries to compensate for the decreased oxygen level in the blood through accelerated breathing.

Common symptoms also include headaches. Studies show a link between iron deficiency anemia and frequent headaches, particularly in women, likely related to impaired oxygen supply to the brain.

In anemia, accelerated or irregular heartbeat may be observed, as the heart needs to pump more blood to provide organs with oxygen. This can lead to tachycardia.

External changes may also indicate a problem. Dry, brittle hair and skin, as well as increased hair loss, may be associated with insufficient blood supply.

Iron deficiency affects mucous membranes. Some people may experience swelling of the tongue, burning, or cracks in the corners of the lips.

Another symptom is the restless legs syndrome, characterized by an irresistible urge to move the legs at rest, especially at night, disrupting sleep.

In the later stages of anemia, nails may change—they become brittle and may take on a spoon-like shape.

Among less common signs are cold hands and feet, reduced appetite, frequent infections, and pica—a craving for non-food items, most often observed in pregnant women and children.

Symptoms of Anemia in Children and the Elderly

In children, iron deficiency anemia may manifest as pallor, rapid fatigue, irritability, and delays in development. In the elderly, symptoms may be masked by usual age-related changes such as concentration problems and muscle weakness. The situation is complicated by the fact that older adults often take medications that may reduce iron absorption.

Doctors emphasize the necessity of consulting specialists and undergoing blood tests in the presence of symptoms of iron deficiency. Without treatment, iron deficiency anemia can lead to serious complications, such as heart problems and increased susceptibility to infections.
