Over 45s’ bad hangover
IF YOU’RE over 40, the chances are you like a drink. A recent survey in Britain found “empty nester” mothers were at the forefront of a middle-aged drinking epidemic, with 28% of women over 45 admitting they drank as much or more than their grown-up children.
It’s also those 65 and over who are most likely to drink on five consecutive nights each week.
But it’s not all bad news. Last week, Danish research published in the journal BMJ online found that Alzheimer’s patients who consumed two to three drinks daily had a 77% lower risk of death than those that drank less or nothing.
Still experts are urging us to spare a thought not only for the short-term effects of alcohol on our brains, but also the damage our drinking habits are doing to our bodies as we approach middle age.
“Alcohol affects just about every system because it’s a small molecule that goes everywhere in the body,” says Paul Wallace, emeritus professor of public health at University College London and medical director of the charity Drinkaware. “From the gut to the heart, the blood vessels to the skin, its effects are all-pervasive.” But why are the effects worse after 40? “The organs that metabolise alcohol, such as the liver and stomach, shrink as you get older, so alcohol stays in your system longer,” says Dr Tony Rao, consultant old age psychiatrist at the Maudsley National Health Service (NHS) Foundation Trust.
This could explain that wretched two-day hangover post-40. “Plus, the total fluid in the body is a lot less – we get more dehydrated as we get older – so because alcohol is distributed in blood which will be more concentrated, it won’t be broken down as quickly as it would in the bloodstream of a 20-year-old,” he says.
Here’s what else alcohol is doing to your body after 40:
Brain
“ALCOHOL gets through the blood-brain barrier where it works as a depressant,” says Wallace. “We feel quite excited and stimulated when we drink because it’s having a depressing effect on controlling behaviours such as judgment, self-monitoring, planning and reasoning. “Over time this gives you a higher propensity to mood problems such as anxiety and depression.”
In his NHS clinic, specialising in alcohol problems, Rao sees people in their 60s with subtle alcohol-related brain damage after a lifetime of casual drinking. “I always say to my patients, ‘Your brain is affected a lot earlier than your liver’,’’ he says. “Before we see the cirrhosis we see depression and problems with impulse control, moodiness, problems making complex decisions.”
The good news is the damage can be reversed after just six months of not drinking, he says. “People who regularly drink in excess may develop alcohol-related dementia or be at higher risk of other forms of dementia,” says Dr Simon Ridley, director of research at Alzheimer’s Research UK.
“The effect of low or moderate alcohol intake on the brain is still being understood. Some studies have suggested that moderate alcohol intake could also have a protective effect on the brain possibly due to cardiovascular or inflammatory mechanisms but further research is needed.”
Skin
ALCOHOL causes flushing, says Professor Nick Lowe, consultant dermatologist and spokesman for the British Skin Foundation. “This can trigger rosacea, a chronic redness in the skin, because the blood vessels enlarge and produce more blood flow.”
And those spots after a night out? “Alcohol can make people stressed and anxious, and this produces the androgen hormones that stimulate acne,” says Lowe.
As for the reason heavy drinkers look a little worse for wear: “The skin becomes dehydrated, and the fluid lost can lead to flakiness and puffiness around the eyes. Plus, the excess sugars you’re consuming, especially with beer and wine, damage the DNA and collagen in the skin, which can lead to more rapid ageing.”
Heart
PEOPLE who regularly binge drink – consuming double the daily limit of three to four units for a man and two to three units for a woman or more in one session – dramatically increase their risk of stroke, says Wallace.
Drinking raises blood pressure, which increases heart attack and stroke risk.
Excessive alcohol also damages the heart’s ability to pump, cardiomyopathy, which increases risk of heart failure, says Dr Mike Knapton, associate medical director of the British Heart Foundation.
But surely a glass of red wine is good for the heart? Knapton agrees research does confirm this, “but the benefits come from
less than one glass of red wine a day”.
Liver
LIVER disease has risen by a staggering 400% since the ’70s. “Those at risk are not just chronic alcohol abusers, but also middle-aged professionals who drink a little too much most nights,” King’s College Hospital liver unit consultant hepatologist Dr Debbie Shawcross said.
“The liver may start out a little fatty and then if you continue drinking heavily between, say, 40 and 55, the fat and inflammation creates scar tissue and the liver shrinks and – for about one in six people – can lead to cirrhosis or liver disease.”
The liver has the ability to heal itself and the British Liver Trust suggests three consecutive non-drinking days a week to allow it to regenerate – it also has an iPhone app, called Spruce, to help work alcohol-free days into your week.
Cancer risk
“IN terms of cancer risk, there is no safe level of drinking,” says Nicola Smith, health information officer for Cancer Research UK. “The cancers most closely linked to alcohol consumption are those of the mouth, oesophagus, bowel, breast and throat.
“The more you drink, the higher your risk because ethanol in alcohol is broken down into acetaldehyde, which damages DNA. Plus, if you’re smoking and drinking, you’re increasing your risk of mouth and throat cancer because alcohol makes cells more responsive to toxins in tobacco smoke.”
Fertility
A DANISH study of thousands of couples who had stopped contraception in order to conceive found that teetotal women fell pregnant much sooner than even “social” drinkers and also had a lower miscarriage rate. Even where couples resort to IVF, a US study found that moderate drinking (half a bottle of wine a week) was associated with an 18% reduction in success rates for women. “For men, excessive alcohol consumption lowers testosterone levels and reduces sperm quality and quantity,” Midland Fertility medical director Dr Gillian Lockwood said.
Weight
ALCOHOL contains seven calories per gram, nearly as much as fat (nine calories), and the body recognises its by-products as toxins and breaks these down ahead of the nutrients in food, says Robert Hobson, coauthor of The Detox Kitchen Bible. “When the body gets around to metabolising the food, it may no longer require the calories, so they get stored as fat.”
As a sugar source, alcohol raises insulin and turns on fat storage by increasing fatty deposits in the liver and, in middle age, excess can lead to fat storage around the stomach – “beer belly”. – The Daily Telegraph
