CAMH Review Links Alcohol to 60-Plus Diseases, Finds Some Damage Reversible
5 articles · Updated · camh.ca · May 14
A CAMH-led systematic review in Addiction found alcohol is fully attributable to more than 60 diseases and injuries under the WHO’s ICD-11, reinforcing alcohol as a major driver of illness.
The review tied drinking to infectious diseases, cancers, cardiovascular disease, type 2 diabetes, neuropsychiatric disorders, gastrointestinal disease and injuries, noting even low alcohol use can impair judgment, balance and reaction time.
Some harms can ease when drinking stops or falls: injury and sexually transmitted infection risks decline quickly, some cardiovascular effects may improve within days to weeks, and some brain changes may partly recover over time.
Long-term heavy drinking can leave lasting damage—especially cirrhosis and heart disease—and the authors said evidence remains insufficient to rule out any heart benefit from light drinking, while concluding alcohol’s harms outweigh potential benefits.
Alcohol is linked to over 60 diseases, but how much of the damage can your body actually reverse?
With alcohol tied to cancer and dementia, why do we still cling to its potential heart health benefits?
Alcohol and Health in 2026: Landmark Review Confirms Massive Global Disease Burden and Calls for Policy Action
Overview
A major scientific review published in 2026 brought together strong evidence confirming that alcohol is a direct cause of many health problems. This review used a robust approach, including dozens of meta-analyses and genetic studies, to show that alcohol is a major contributor to disease and injury. The findings make it clear that the harms of alcohol far outweigh any possible benefits. Experts agree that the evidence leads to a cautious but clear conclusion: alcohol has a profound negative impact on health, and reducing consumption is important for preventing disease and injury.
