Alcohol and blood pressure
Alcohol can have a serious long-term effect on blood pressure
Drinking alcohol increases your blood pressure and repeated drinking causes sustained high blood pressure.
Alcohol consumption is an entirely preventable cause of severe hypertension (the medical name for sustained high blood pressure) in both men and women.1 Untreated high blood pressure greatly increases your risk of stroke and heart attack.2
What is high blood pressure?
A normal heart pumps blood around the body easily, at a low pressure. Having high blood pressure means that your heart must pump harder, and the arteries have to carry blood that’s flowing under greater pressure. This puts a strain on your arteries and your heart, which in turn increases your risk of a heart attack, stroke or kidney disease.3
What are the symptoms of high blood pressure?
You can't usually feel or notice high blood pressure. In fact, many people may not know they have it. This is because high blood pressure very rarely causes any obvious symptoms until a serious acute event such as a heart attack or stroke.4
The best way of knowing if there’s a problem is to have your blood pressure measured. You can have this done at your GP surgery, some local pharmacies, at your NHS Health Check or you can buy a reliable blood pressure monitor from the pharmacist.
What causes high blood pressure?
There isn’t always a clear explanation as to why someone’s blood pressure is high. However, there are several factors that can play a part in increasing the risks of developing hypertension including:5
- Regularly drinking above the low risk drinking guidelines (no more than 14 units a week)
- Not doing enough exercise
- Being overweight
- A family history of high blood pressure
- Consuming too much salt
How to reduce high blood pressure
To lower your blood pressure, you should:6
- Cut down on alcohol
- Exercise regularly
- Lose weight, if you are overweight
- Eat a healthy diet, including reducing your salt intake
How to reduce your drinking
The UK Chief Medical Officers' (CMOs’) low risk drinking guidelines advise that both men and women should drink no more than 14 units a week, to keep health risks from alcohol low. If you do choose to drink, it is best to spread your drinks over three or more days with several drink-free days, and no bingeing.7 Here are some tips for reducing your drinking
Keep track of what you’re drinking
Our free MyDrinkaware app can track your alcohol consumption, calculate units and calories, and set goals to help you moderate your drinking.
Switch to low or alcohol-free options
Swapping a standard beer, wine or spirit for a low or alcohol-free drink could help you cut down your drinking. Because they have less alcohol in them, switching from full-strength to a drink with a lower alcohol content can be a good way to cut your units.
Have several drink-free days a week
Taking more drink-free days each week is an easy way to cut back and improve your health.
