Iron is an essential mineral for maintaining healthy red blood cells. It plays a role in transporting oxygen from the lungs to various tissues in the body and assisting muscle metabolism. However, a deficiency in iron can lead to various symptoms such as fatigue, pallor, and dizziness. It is important to accurately understand and respond to the signals indicating iron deficiency in the body. Based on health information from the Cleveland Clinic in the United States, we will explore the symptoms that occur when the body lacks iron.

1. Fatigue and lethargy

The most common symptom of iron deficiency is unexplained fatigue. If you feel tired or weak despite getting enough sleep, it may be due to a decrease in hemoglobin caused by iron deficiency, which hampers oxygen supply. Iron deficiency is also associated with insomnia and restless leg syndrome, which can further worsen sleep quality.

 

2. Hands and feet are always cold

 

Iron deficiency can manifest as a sensation of cold fingers and toes. This is because a lack of hemoglobin reduces blood circulation, leading to insufficient oxygen supply to the hands and feet. If you feel colder than others even at sufficiently warm temperatures, it may be worth suspecting iron deficiency.

3. Skin becomes paler than usual

 

If iron deficiency occurs, blood circulation decreases, and the skin may appear paler than usual. The pallor can vary depending on skin tone; it is more noticeable across the entire face in individuals with lighter skin tones. In those with darker skin tones, it appears more prominently in the mouth or mucous membranes of the eyes.

 

4. Dizziness and vertigo

 

If iron deficiency occurs, the supply of oxygen to the brain decreases, which can frequently cause dizziness or lightheadedness. However, these symptoms can also be caused by various other reasons besides iron deficiency, so it is important to check whether they appear along with other symptoms of iron deficiency.

 

Frequent headaches

 

Oxygen deficiency can cause headaches. When blood vessels swell due to iron deficiency, increased pressure can lead to headaches. According to studies, patients with iron deficiency anemia often experience chronic headaches or migraines.

 

6. Weakened hair and nails

 

Iron deficiency causes hair and nails to become weak and easily break. In severe cases, a condition called "spoon nails (koilonychia)" may occur, where the nails bend inward. This can be caused by abnormalities in blood flow and nutrient supply around the nails. Additionally, iron deficiency can affect hair growth and lead to hair loss.

 

7. Unusual eating habits

 

Iron deficiency can cause a condition called pica, which leads to cravings for foods like ice and rice grains. In the United States, it is reported that about 25% of patients with iron deficiency experience a craving for ice, known as 'pica for ice.'

 

Iron deficiency detection and management methods

 

If symptoms of iron deficiency appear, consult with medical staff and have a blood test to confirm whether there is a deficiency. The main tests include △Complete Blood Count (CBC) △Serum Iron Test △Ferritin Level Measurement.

 

To prevent or manage iron deficiency, it is necessary to consume iron-rich foods. Typical iron-containing foods include △legumes △dried fruits △eggs △lean meat △salmon △iron-fortified grains △peas △tofu △dark green vegetables. In particular, consuming these foods together with vitamin C-rich foods such as oranges, tomatoes, and strawberries can enhance iron absorption.

 

Taking iron supplements can also be an option. However, iron supplements may cause side effects such as nausea, diarrhea, and constipation, so it is essential to take them after meals or adjust the dosage. If iron deficiency is left untreated, it can lead to serious consequences such as heart problems, pregnancy complications, and growth delays, so it is important to carefully observe the signals your body sends.
