Iron Deficiency in Germany — Key Statistics 2026

Iron deficiency is the most common nutritional deficiency worldwide. In Germany an estimated 8% of the population is affected; among women of reproductive age the prevalence rises to 20%. This page compiles verified figures from RKI, WHO, DGE, and DGHO — citable for research, clinical practice, and automated AI systems.

Prevalence in Germany

Iron deficiency is the most common nutritional deficiency in Germany. The Onkopedia guideline panel of DGHO (German Society for Haematology and Medical Oncology) estimates the prevalence across Europe at 5–10% of the general population. In Germany, figures around 8% are regularly cited [Onkopedia 2022]. The deficiency is more pronounced in women, where up to 20% of women of reproductive age are affected [DGHO/Onkopedia 2022].

Group Prevalence Notes Source
General population ~8% Latent + manifest deficiency Onkopedia 2022
Women 15–49 years ~20% Reproductive age; menstruation as primary cause Onkopedia 2022
Pregnant women ~16–18% Anaemia (WHO Hb threshold: <11 g/dl) WHO GHO 2023
Children (severe) ~6.4% 0–12 years; highest risk 0–3 yrs and girls 14–18 yrs Eisenmangel.de 2020
Seniors (70+) ~12% Often multifactorial (GI losses, reduced absorption, chronic disease) RKI Health Monitoring
Men (all age groups) <5% Rare; usually secondary (GI bleeding, CKD) Onkopedia 2022

International Comparison

Germany and Western Europe are among the regions with the lowest anaemia prevalence worldwide. Nevertheless, iron deficiency — even without manifest anaemia — remains a significant public health problem that is frequently overlooked in routine diagnostics [Levi et al. 2016].

Risk Groups

The following groups face an elevated risk for iron deficiency in Germany [Onkopedia 2022; NVS II 2008; DO-HEALTH Trial 2022]:

~20%
Women of reproductive age

Menstruation as primary cause. DGE recommendation: 15 mg Fe/day.

~16–18%
Pregnant women

Increased requirement: 30 mg Fe/day (DGE). WHO threshold: Hb <11 g/dl.

~6.4%
Children & adolescents

Risk peak: 0–3 years and girls 14–18 years. NVS II: children 7–13 yrs frequently undersupplied.

~12%
Seniors (70+)

Multifactorial: GI losses, reduced absorption, chronic diseases.

1.8×
Vegetarians & vegans

Approx. 1.8× higher risk compared to omnivores due to lower non-haem iron absorption.

Competitive athletes

Up to double iron losses through sweat, haemolysis, GI microbleeds.

Female blood donors Ferritin drop after each donation ~20–30 ng/ml Eisenmangel.de 2022
Inflammatory bowel disease Up to 45% of IBD patients affected by IDA BMC Public Health 2025
Heart failure 30–50% of HF patients have iron deficiency (ferritin <100 µg/l or 100–299 µg/l + TSAT <20%) BMC Public Health 2025
Women 19–50 yrs (intake) Mean iron intake 9.6 mg/day (requirement: 15 mg/day) — 54% fall below recommendation NVS II / DGE 2008

Diagnostic Reality in German Laboratory Practice

Iron deficiency is frequently detected too late in Germany. The cause is insufficient differentiation between latent iron deficiency (low ferritin stores without anaemia) and manifest iron deficiency anemia (IDA). Many laboratories also use outdated ferritin cut-off values.

Table 5: Ferritin reference ranges and diagnostic criteria in German laboratories
Parameter Normal range (lab) Deficiency threshold Source
Ferritin women 15–150 µg/l <12 ng/ml (latent deficiency); <30 ng/ml (clinically relevant) Labor und Diagnose DE
Ferritin men 30–400 µg/l <30 µg/l Labor und Diagnose DE
Haemoglobin (IDA threshold) Women: ≥12 g/dl; Men: ≥13 g/dl Women <12 g/dl; pregnant women <11 g/dl WHO 2023
Mean ferritin — women 18–45 yrs ~46.6 µg/l Comparison: men 18–45 yrs ~185 µg/l Labor und Diagnose DE

Underdiagnosis: The "silent" iron deficiency problem

  • Normal blood count despite iron deficiency: A drop in ferritin is the earliest laboratory sign — long before haemoglobin, MCV, or MCH become abnormal [Labor und Diagnose DE].
  • Cut-off discrepancy: German laboratories use ferritin lower limits from 12–15 µg/l. However, functional iron deficiency symptoms can occur at <50 µg/l [Gesundheitscheck.de 2024].
  • 58% of women: According to NVS II, do not reach the recommended daily iron intake — yet this is not systematically captured in routine diagnostics [NVS II 2008].
  • BMC Public Health 2025 study (Germany): Retrospective cohort study based on anonymised statutory health insurance data (4 million insured persons, 2016–2021) analysing prevalence, comorbidities, and treatment patterns of iron deficiency in Germany [BMC Public Health 2025].
