Iron is an essential mineral that helps the body produce haemoglobin, the protein in red blood cells responsible for carrying oxygen throughout the body. When the body does not have enough iron, it can lead to iron deficiency and, in some cases, iron-deficiency anaemia.
Women are at greater risk of iron deficiency than men because of menstrual blood loss, pregnancy, and breastfeeding. Health experts say recognising the early signs can help prevent serious health complications.
What Causes Iron Deficiency?
Several factors can reduce the body’s iron levels, including:
- Heavy menstrual bleeding.
- Pregnancy, when iron requirements increase.
- Breastfeeding.
- A diet low in iron-rich foods.
- Blood loss from stomach ulcers or other digestive conditions.
- Poor absorption of iron due to certain medical conditions, such as coeliac disease.
- Frequent blood donation.
In many cases, more than one factor contributes to iron deficiency.
Common Signs and Symptoms
Iron deficiency often develops gradually, and symptoms may be mild at first.
Common symptoms include:
- Constant tiredness or fatigue.
- Weakness.
- Pale skin.
- Shortness of breath during normal activities.
- Dizziness or light-headedness.
- Frequent headaches.
- Cold hands and feet.
- Brittle nails.
- Hair loss.
- Difficulty concentrating.
As iron levels continue to fall, symptoms may become more severe.
Less Common Symptoms
Some women with significant iron deficiency may experience:
- Craving non-food items such as ice, clay, or starch (a condition known as pica).
- Restless legs syndrome.
- A sore or swollen tongue.
- Cracks at the corners of the mouth.
These symptoms should be discussed with a healthcare professional.
Who Is Most at Risk?
Women who may have a higher risk of iron deficiency include:
- Women with heavy menstrual periods.
- Pregnant women.
- Women who have recently given birth.
- Vegetarians or vegans who do not consume enough iron-rich foods.
- Women with digestive disorders that affect nutrient absorption.
- Women with chronic illnesses that cause ongoing blood loss.
Foods Rich in Iron
Eating iron-rich foods can help maintain healthy iron levels.
Good sources include:
- Lean red meat.
- Chicken.
- Fish.
- Liver (in moderation and according to medical advice, especially during pregnancy).
- Beans and lentils.
- Spinach and other leafy green vegetables.
- Iron-fortified breakfast cereals.
- Pumpkin seeds.
Eating foods rich in vitamin C, such as oranges, strawberries, tomatoes, and bell peppers, alongside iron-rich foods can improve iron absorption.
How Is Iron Deficiency Diagnosed?
A healthcare provider may recommend:
- A physical examination.
- Blood tests to measure haemoglobin and iron stores.
- Additional tests to identify the underlying cause if necessary.
Finding and treating the cause of iron deficiency is just as important as replacing lost iron.
Treatment
Treatment depends on the severity and cause of the deficiency.
It may include:
- Eating more iron-rich foods.
- Iron supplements prescribed by a healthcare professional.
- Treating heavy menstrual bleeding or underlying medical conditions.
- In severe cases, iron may be given intravenously under medical supervision.
Iron supplements should only be taken under medical advice, as excessive iron can be harmful.
When Should You See a Doctor?
Seek medical advice if you experience:
- Persistent fatigue.
- Shortness of breath without a clear cause.
- Heavy menstrual bleeding.
- Frequent dizziness.
- Pale skin.
- Symptoms that do not improve despite eating a healthy diet.
Early diagnosis can help prevent complications and improve overall health.
The Bottom Line
Iron deficiency is one of the most common nutritional deficiencies among women. Heavy periods, pregnancy, poor dietary intake, and certain medical conditions can all contribute to low iron levels. Recognising the warning signs and seeking timely medical care can help restore healthy iron levels and prevent iron-deficiency anaemia.
