Iron deficiency and the important role of iron in the body
Iron is an essential mineral that plays a central role in many important physiological functions. This is the main component of hemoglobin - a protein in red blood cells, responsible for transporting oxygen from the lungs to organs and tissues in the body.
In addition, iron also helps support the immune system, maintain muscle function and participate in energy production. When the body lacks iron, hemoglobin synthesis is interrupted, reducing the body's ability to transport oxygen and leading to anemia. As a result, the body is not provided with enough oxygen, causing a series of uncomfortable symptoms, including a feeling of cold hands and feet, especially in areas far from the heart such as the limbs.
Why does iron deficiency cause cold hands and feet?
According to Dr. Brunda MS - Consultant Internal Medicine at Aster CMI Hospital, Bengaluru (India), iron deficiency causes the body to not produce enough hemoglobin, thereby reducing the amount of oxygen to the tissues. Limited blood circulation, especially in the limbs, can often cause cold hands and feet.
Other symptoms of iron deficiency to note
Not only cold hands and feet, iron deficiency can also manifest itself through many other signs. Some common symptoms include:
Prolonged fatigue
Facial congestion, headache
Difficulty breathing while trying
Nails are brittle and brittle
Heavy hair loss
Red, swollen or burning tongue
Difficulty concentrating, easily irritable
At restless legs syndrome (RLS)
Cravings for non-food substances such as stone, soil (pica)
Increased risk of infection
Early recognition of these symptoms can help detect iron deficiency in a timely manner and treat it more effectively.
Diet can help improve iron deficiency
Dr. Brunda recommends increasing iron-rich foods in your diet, including:
Red meat, poultry, fish
Beans: lentils, soy, black beans
Dark green vegetables such as spinach, kale
Whole grains and foods are rich in iron
Combined with foods rich in vitamin C such as oranges, lemons, strawberries, bell peppers will help increase the absorption of iron from plants. However, in cases of severe iron deficiency or due to medical conditions, patients may need to take iron supplements or even receive iron int most effectively as prescribed by a doctor.
Note
Dr. Brunda says cold hands and feet can be caused by bad weather or circulation, but they are also a sign of iron deficiency or anemia. Early identification, regular check-ups and maintaining a healthy diet help prevent iron deficiency. If you have symptoms such as fatigue, dizziness, shortness of breath, hair loss, consult your doctor for timely diagnosis and treatment.
