Indian mothers lay strong emphasis on adding plenty of greens to their kids' daily diet. Well, they have a legitimate reason for that, which is iron. Iron is an important mineral, which is used to form haemoglobin. Haemoglobin is a protein present in the red blood cells that helps in the transportation of oxygen throughout the body. Simply put, iron is required to ensure that your body gets the required amount of oxygen. If you would have low iron content in your blood, you are most likely to develop iron deficiency anaemia. This type of anaemia usually occurs either due to poor iron intake or inadequate iron absorption from the food you are eating. Untreated iron deficiency can leave you tired and short of breath. Let us look at some of the common signs and symptoms of iron deficiency in the body.

What are the symptoms of a lack of iron in the blood?

It usually takes a long time for iron deficiency anaemia to develop. People usually don't know they have it until they experience the severity of the following symptoms:

1. Tiredness or fatigue

The person may feel even less energy than usual to perform their daily activities without doing any strenuous activity.

2. Pale or yellow skin

Due to the lack of haemoglobin, a person with low iron content in their blood may look sick and pale. Their skin may appear lighter than normal.

3. Shortness of breath

When doing a strenuous activity or climbing up a flight of stairs, the person may feel short of breath due to the lack of enough oxygen in the blood.

4. Fainting

The person may feel light-headed without performing any strenuous task due to the lack of enough oxygen reaching the brain.

5. Headache

The person may experience frequent throbbing headaches. Some people may also experience migraine attacks.

6. Abnormal heartbeat

Low iron levels cause the heart to work harder to deliver oxygen to the blood, resulting in a high pulse rate and irregular heartbeats.

7. Chest pain
Due to improper circulation of oxygen in the body, the person may feel chest pain.

8. Cold feet and hands

Low iron content in the blood can lead to cold feet and hands as the body is unable to keep itself warm.

9. Brittle nails and hair

Iron is required to produce a protein known as keratin. The low iron content in the blood can lead to low keratin, which causes brittle nails and hair.

10. Restless legs syndrome

The person may have an unpleasant sensation in the legs especially when you are lying down.

You need to visit your doctor if you experience any or all of these symptoms. Pregnant women are especially cautioned to consult their doctor if facing these symptoms, as low blood iron content can severely affect the baby.
