The 10 most important symptoms of iron deficiency – the main cause of anaemia

Iron deficiency is the main cause of anaemia, the most common nutritional deficiency in the world. It affects 33 per cent of non-pregnant women, 40 per cent of pregnant women and 42 per cent of children worldwide.

Signs of iron deficiency
Iron deficiency manifests itself in various symptoms, which can vary depending on the severity and individual factors:

1. Fatigue and exhaustion
One of the most common signs of iron deficiency, as iron is necessary for the formation of haemoglobin, which transports oxygen in the body.

2. Paleness
Less haemoglobin can lead to a lighter skin colour, particularly visible on the inside of the eyelids and the mucous membrane of the mouth.

3. Shortness of breath and palpitations
During physical exertion, iron deficiency can lead to shortness of breath and irregular heartbeat.

4. Dizziness and headaches
These symptoms occur when the brain does not receive enough oxygen.

5. Hair loss and brittle nails
Iron is important for cell growth and influences the condition of hair and nails.

6. Altered cognitive functions
Iron deficiency can cause concentration problems and reduced mental performance.

7. Sensitivity to cold
People with iron deficiency are more likely to suffer from cold hands and feet. This is due to reduced oxygen supply and poorer blood circulation.

8. Restless legs syndrome
Iron deficiency is associated with restless legs syndrome, a disorder characterised by unpleasant sensations in the legs and the urge to move them.

9. Weakened immune system
Iron is important for a healthy immune system. A deficiency can weaken immunity and increase susceptibility to infections.

10. Cracked corners of the mouth and inflammation of the tongue
Iron deficiency can lead to changes in the oral cavity, including cracked corners of the mouth and a smooth, inflamed tongue, known as glossitis.

These symptoms can vary in severity depending on the individual and the severity of the iron deficiency. Recognising them and responding appropriately is an important step in avoiding more serious health problems.

Causes of iron deficiency

• Insufficient iron intake
  A diet low in iron-rich foods, such as a vegetarian or vegan lifestyle, can increase the risk of iron deficiency.
• Inhibitors in food
  Certain substances in plant-based foods, such as phytates, oxalates and polyphenols, can inhibit iron absorption.
• Increased iron requirements
  Changes such as pregnancy, growth spurts in childhood and intense physical activity increase the need for iron.
• Blood loss
  Heavy menstruation or internal bleeding can lead to significant iron loss.
• Iron absorption disorders
  Diseases such as coeliac disease or Crohn's disease can impair the body's ability to absorb iron.
• Lack of combination with vitamin C
  The absorption of plant-based iron can be improved by combining it with foods rich in vitamin C.

Reference values for iron absorption
The German Nutrition Society (DGE) provides age- and gender-specific recommendations for daily iron intake, ranging from 10 mg/day for men and non-menstruating women to 30 mg/day for pregnant women.

Treatment of iron deficiency

• Dietary changes
  The basis for treating iron deficiency is an iron-rich diet. This includes foods such as red meat, legumes, nuts and dark green leafy vegetables.
• Iron supplements
  Iron supplements play an important role in restoring iron stores. In addition to an iron-rich diet, it may be beneficial to take products such as plantoCAPS PHYTOFERRIN +C | IRON capsules . These contain buckwheat germ powder as a plant-based source of iron
  and are enriched with rosehip extract and vitamin C (calcium L-ascorbate), which supports iron absorption and utilisation in the body and helps to effectively replenish iron stores.
• Treatment of underlying causes
  It is important to seek medical treatment for any medical reasons for iron deficiency, such as internal bleeding or diseases that impair iron absorption.

Iron deficiency is a common health problem that is associated with a range of symptoms and can have many causes. Treatment requires a comprehensive understanding of individual dietary habits, lifestyle and any medical conditions that may cause a deficiency. Through a balanced diet, adjusting eating habits and using high-quality supplements such as plantoCAPS PHYTOFERRIN +C | IRON capsules, iron deficiency can be effectively combated and well-being increased.
