It has become increasingly clear that many people in this country are putting themselves at risk because they are continuing to drink above their recommended weekly units. Most of these people are not drunk drivers in police cells or antisocial drinkers arriving at A&E departments on Saturday night. They are people who come to see us at our chronic disease clinics or for treatment for an acute illness. The inclusion of questions about alcohol in NHS Health Checks is the ideal opportunity to discuss the potential risks of excessive drinking, and this special issue explains how we can help patients to choose a healthier approach to alcohol.
