Drinking more than the recommended limits of alcohol (alcohol misuse) can lead to serious health problems.
Most people think that alcohol is fairly harmless and just something to be enjoyed. Other than a few ill-effects; a hangover the next day or putting on a little bit of weight, many people do not know about the unseen damage alcohol can cause to your body.
Each year in the UK, over 250,000 people are admitted to hospital solely because of alcohol-related illnesses and a further one million people are admitted with alcohol-related illnesses being partially responsible.
Alcohol-related illness accounts for almost three quarters of all admissions to Accident and Emergencies (A&E) from midnight until five am at weekends. Each year over 6,500 people will die because of an illness directly related to alcohol and alcohol-related admissions and deaths costs the NHS over £3.5 billion per year.
There are three main types of alcohol misuse:
- hazardous drinking: drinking over the recommended limits
- harmful drinking: drinking over the recommended limits and experiencing alcohol-related health problems
- dependent drinking: feeling unable to function without alcohol
Many people who have alcohol-related health problems aren’t alcohol dependant
Drinking heavily, over a short period, leads to a rapid rise in blood alcohol concentration and consequently to ‘drunkenness’. The effect on behaviour varies from one person to another and ranges from relaxation and exhilaration, to memory loss, violent behaviour and nausea. In more severe cases it can lead to coma.
A rapidly rising blood alcohol level can cause you to say things or act in a way that might embarrass you later. It can also lead to physical accidents, vehicle accidents, unsafe sex and can make you more vulnerable to a physical attack; putting you at risk of being infected with viral hepatitis, HIV and other STI’s (sexually transmitted infections).
Very high blood alcohol levels can cause your brain’s control over the respiratory system to become paralysed, cause heart irregularities, strokes and possibly loss of life.

It can be quite technical, so please discuss any content that you are unsure about with your medical team.
