Chronic spontaneous hives linked to wider health risks
Over ten years, adults with chronic spontaneous hives had 11.0% to 24.3% higher relative risks across four health outcome groups than controls with moles.
Our read
Populations- Studied:
- Cohort study of 105,963 adults with chronic spontaneous urticaria, against adults with moles
- What changed:
- Cognitive, cardiovascular, metabolic, and substance use disorder risks were 11.0% to 24.3% higher with chronic spontaneous hives than with moles
- The catch:
- Treatment differences could have contributed to the higher risks despite matching
- In the record:
- One of 4 papers on chronic spontaneous urticaria on record: 4 with results in people.

Adults with chronic spontaneous urticaria—recurring hives without a clear trigger—were compared with adults with moles in a retrospective cohort analysis of electronic health records. Each matched group included 105,963 adults. Those with urticaria had at least two diagnoses six weeks apart. The analysis assessed new diagnoses over ten years after excluding preexisting diagnoses.
Urticaria was associated with higher risks of dementia or memory loss, heart and blood vessel disease, metabolic disease, and substance use disorders. Metabolic diseases affect how the body uses or stores energy. Substance use disorders showed the largest relative increase. When researchers excluded alcohol- and tobacco-related diagnoses from that outcome, its relative risk increase was 31.9% compared with controls.
Why it matters
Cognitive and cardiovascular health matter as adults age. The authors call for greater clinical awareness and earlier screening, particularly for cognitive, cardiovascular and metabolic disorders.
Caveats
Differences in treatment or healthcare use could have contributed to the links despite matching. The findings concern adults with chronic spontaneous urticaria, not children or people with other forms of hives.
