What are the risks of alcohol as you get older?

Alcohol and ageing

As you get older, your body becomes less able to cope with alcohol. That's partly because some of your muscle is replaced by fat. What's more, the amount of water in your body gradually goes down - and alcohol is diluted by the water in your bloodstream. That means even if you drink the same amount of alcohol as someone younger, you're likely to have a higher level of alcohol in your blood.

Your liver processes alcohol, and too much alcohol can cause damage to your liver. As you age, the blood flow to your liver is decreased. That means alcohol stays in your liver for longer and can cause more harm.

Medicine side-effects and complications

Your liver also processes a whole host of medicines, which can interact with alcohol. This could mean you get more side effects. For example, painkillers, some antihistamines and some antidepressant medicines can make you feel drowsy, and this is often made worse by alcohol.

It could make you more susceptible to complications. Drinking alcohol with some diabetes medicines increases your chance of dangerous low blood sugar, and taking it with the blood-thinner warfarin could increase your chance of bleeding.

Dizziness and falls

If your blood pressure is too high, it raises your odds of developing heart attack and stroke. That's why it's so important to get your blood pressure checked regularly as you age, and to take medicine to control it if needed.

But as you get older, your body's ability to keep your blood pressure high enough if you become dehydrated, or stand up too quickly, begins to slow down. That means you may be prone to funny turns - feeling lightheaded if you stand up too fast or get up out of bed. Drinking alcohol increases your chance of these funny turns, and this dizziness makes you more susceptible to falls.

Avoiding falls depends on a combination of reflexes, hearing, coordination, eyesight and muscle strength. Even a small amount of alcohol can slow down your reflexes and reaction time further. This is another reason alcohol makes you more likely to have a fall as you get older. And if you do slip, you're more likely to break a bone even with a minor tumble, because your bones tend to become thinner with age.

Alcohol, age, and cancer risk

In the longer term, drinking alcohol increases your likelihood of developing several cancers. For some, such as breast cancer, there's no lower level where drinking is safe. A unit of alcohol is around half a pint of normal strength beer or a single pub measure of spirits - a standard glass of wine has about 2.5 units. And even 1 unit of alcohol a day increases your chance of breast cancer by 7-11%.

The risks of cancer increase for men, too, even at lower levels of drinking.

Alcoholism and problem drinking

Many people drink alcohol. For some, alcohol is something that they enjoy in moderation. Other people drink alcohol at levels that are likely to lead to physical or mental health problems. Some people can find it very difficult to control, or stop, their drinking.

How to drink less as you get older

Research shows that older people may turn to alcohol as a result of changes in their circumstances. This could be because they are retired and don't have as much to occupy their time. They may be less mobile and can't get out to socialise as much, or because they're mourning the loss of a loved one.

Of course, many older people have highly fulfilling, healthy lives. But staying safe and well takes a few more precautions as time passes. Keeping your alcohol intake moderate as you get older is a really sensible start to living a longer, healthier life.

It’s also so important to try and keep your mind and body as active as you can as you get older. You don't need to train for a marathon - a regular gentle walk can help you reconnect with nature, and even better if you go with a friend.
