A million lives at risk from smoking, drinking and obesity in England

Triple lifestyle threat may slash 20 years off life and strain NHS, experts warn

Key points from article :

A new analysis of the Health Survey for England by the charity Action on Smoking and Health (ASH) reveals that around one million UK adults are at severe risk of premature death due to the combination of smoking, heavy drinking, and being overweight or obese. Referred to as the “triple threat,” this trio of risk factors dramatically increases the likelihood of developing life-threatening illnesses such as cancer, heart disease, stroke, type 2 diabetes, and liver disease.

According to the study, about 22% of adults in England—or 10 million people—have at least two of these risk factors. Meanwhile, 2%—equating to one million individuals—are affected by all three, placing them in the highest risk group. Experts, including Professor Sir Ian Gilmore, chair of the Alcohol Health Alliance, say this combination can cut up to 20 years off a person’s life. Gilmore stressed that the compounded impact of these behaviours is greater than the individual risks added together, and they place an increasing burden on the NHS and the economy.

Public health leaders are urging the government to tackle these interconnected issues with a coordinated strategy, rather than treating them separately. Katharine Jenner of the Obesity Health Alliance and Caroline Cerny from ASH emphasized that these aren’t just personal failings, but outcomes shaped by industry practices that promote harmful products. They called for policy reforms including minimum alcohol pricing, stricter advertising restrictions, and an expanded sugar tax.

As Health Secretary Wes Streeting prepares to announce a 10-year NHS plan, expected measures include deploying community health workers, encouraging self-monitoring through wearable tech, and investing in addiction treatment. The government also plans a junk food ad ban and a phased tobacco sales ban to help reverse the nation’s growing health crisis.
