Eczema and Multiple Health Conditions: What a 37,193-Person Cohort Found

Dr. Arsy Editorial Team · November 9, 2026

Atopic dermatitis often occurs alongside asthma, allergic rhinitis or food allergy. A Lifelines cohort analysis asked a broader question: was eczema associated with having multiple nonallergic health conditions as well?^[3]

Study size and definitions

The analysis included 37,193 participants, 3,242 of whom reported physician-diagnosed eczema. Researchers combined questionnaires, medication records and clinical assessments across 52 diseases. Nonatopic multimorbidity meant at least two conditions excluding asthma, rhinitis and food allergy.

A severity-related association

Participants with eczema had 1.47 times the adjusted odds of nonatopic multimorbidity. The estimate was 1.74 for moderate-to-severe disease and 1.41 for mild disease. Associations were stronger at higher numbers of conditions. The analysis also identified patterns involving orofacial and cardiometabolic domains.^[3]

What the study cannot prove

Self-reported lifetime eczema and observational data limit causal inference. Shared risk factors, healthcare use, medications, socioeconomic conditions and diagnostic opportunity may contribute. The results do not show that eczema directly causes a specific heart, dental, metabolic or autoimmune disease in an individual.^{[12][13][14][15][16]}

Use the finding for coordination, not alarm

A complete medical history helps clinicians see the whole person. Patients can keep an updated medication list, report new symptoms, and make sure dermatology, primary care, allergy and other clinicians know about relevant diagnoses. Routine screening should follow age, symptoms and established preventive-care recommendations rather than indiscriminate testing.

Questions for a visit

• Are sleep, pain and mental health being assessed alongside the skin?
• Could another condition or medicine be affecting the treatment plan?
• Are preventive care and vaccinations current?
• Which new symptoms need a separate evaluation?

Multimorbidity research supports interdisciplinary awareness. It does not turn a population association into an individual forecast.
