Iron deficiency and its effects: symptoms, causes and treatment

Jul 19, 2023Robert Barabas-Steiner

A lack of iron in the body can lead to a variety of health problems and is a common problem worldwide. Iron plays a crucial role in the production of red blood cells that carry oxygen around the body. When the body does not receive enough iron, it can lead to various symptoms and effects. In this blog post, we will take a closer look at iron deficiency, its symptoms, causes and treatment options, as well as tips to improve iron absorption in the body.

Symptoms of iron deficiency

Iron deficiency can manifest itself in different ways, and symptoms can vary from person to person. Here are some common symptoms to look out for:

01 Tiredness and exhaustion

Iron deficiency can lead to a reduced oxygen supply to the body, resulting in persistent fatigue and lack of energy.

02 Pallor of the skin

Another common sign of iron deficiency is pale skin color, especially on the face, tongue and nails.

03 Shortness of breath

The body tries to compensate for the lack of oxygen by breathing faster. This can lead to shortness of breath and an increased need to breathe deeper.

04 Difficulty concentrating

Iron deficiency can also affect brain function, leading to difficulty concentrating, reduced memory and slowed thinking.

Causes of iron deficiency

There are several causes of iron deficiency. Here are some of the most common:

01 Insufficient iron intake

An unbalanced diet with too few iron-rich foods can lead to a deficiency. Vegetarians and vegans in particular are at higher risk of iron deficiency, as meat is an important source of easily digestible iron.

02 Blood loss

Bleeding, whether due to heavy menstrual bleeding in women or internal bleeding in the gastrointestinal tract, can lead to iron deficiency.

03 Pregnancy

During pregnancy, the need for iron increases because the baby needs iron for its development. If iron intake is not sufficient, this can lead to a deficiency in the mother.

Treatment of iron deficiency

Treatment for iron deficiency aims to restore iron levels in the body. In many cases, this can be achieved by adjusting the diet and taking iron supplements. However, it is important to consult a doctor before taking any supplements to determine the exact needs and correct dosage.

Tips to improve iron absorption in the body

To improve the absorption of iron in the body, the following tips can be helpful:

01 Iron-rich foods

A balanced diet rich in iron-rich foods such as red meat, fish, legumes, green leafy vegetables and fortified cereal products can help maintain iron levels in the body.

02 Vitamin C

Combining iron-rich foods with foods rich in vitamin C can improve iron absorption. Citrus fruits, berries, and peppers are good sources of vitamin C.

03 Avoid caffeine and calcium

Caffeine and calcium can inhibit the absorption of iron in the body. Therefore, it is advisable to reduce the consumption of caffeinated beverages such as coffee and tea and not to combine iron-rich meals with calcium-rich foods.


Iron deficiency can lead to a range of symptoms and should not be underestimated. It is important to recognise the symptoms early and, if necessary, to see a doctor to check the iron levels in the body. By eating an iron-rich diet, possibly in combination with iron supplements and improving the absorption of iron in the body, the deficiency can be corrected and health restored. Remember that a balanced diet and a healthy lifestyle are crucial to supply the body with enough iron and to avoid iron deficiency.
