For some people, having a few drinks at home or in the pub is part of everyday life. And having diabetes shouldn’t get in the way of this.
But when you have diabetes, it’s a bit more complicated. You might want to know whether it's safe to drink alcohol, and how much is okay.
So yes, you can still drink, but you need to be aware of how it can affect your body and how to manage this. For example, drinking can make you more likely to have a hypo, because alcohol makes your blood sugars drop. It can affect your weight too, as there can be a lot of calories in alcoholic drinks.
We’ll give you all the facts here.
Alcohol and risk factors for Type 2
There are several risk factors for Type 2 diabetes, these include your family history, age and ethnic background. We also know you’re more likely to develop it if you’re overweight.
Excess alcohol intake is associated with an increased risk of Type 2 diabetes, but the relationship between alcohol and risk of Type 2 diabetes can be a little bit complicated and staying within government guidelines is the safest way to drink alcohol.
Alcohol can also it can contain a lot of calories, which can lead to putting on weight.
Take a look at our information about risk factors and find out your risk of developing Type 2 diabetes.
To help keep health risks from alcohol at a low level, it’s safest not to regularly drink more than 14 units a week. These guidelines are the same for men and women.
But what does this actually mean when you’re in the pub or having dinner with a glass of wine at home?
It means you shouldn’t drink more than six medium glasses of wine or six pints of lager a week.
But the size of the glass and type of alcohol affects the number of units, so it’s best to check the guidelines at drinkaware.co.uk
If you use insulin or some other diabetes medications like sulphonylureas, you’re more likely to have a hypo. Drinking alcohol can then add to this, because it causes your blood sugar levels to spike or drop. If you’re not sure whether your medication can cause hypos or if they're affected by alcohol, it’s best to speak to your healthcare team.
If you drink a lot or on an empty stomach, you’re even more likely to have a hypo. Your liver works twice as hard when you drink, because it's trying to keep your blood sugar steady and at the same time trying to get rid of the alcohol. It just can’t keep up. So your blood sugar might drop and stay low until your liver has dealt with the alcohol. That’s why you might crave carbs and wake up the next morning with a headache.
Your risk of having a hypo doesn't go away after you stop drinking – it increases, and can last up to 24 hours.
It’s not uncommon for some people to mistake having a hypo for being drunk. So carry hypo treatments around with you and always wear some medical ID. You should also make sure that whoever you’re with knows you have diabetes, and knows how to help with a hypo if you need them to.
Alcohol and your weight
Depending on what you like to drink, there can be a lot of calories in alcohol. So if you’re trying to lose weight, you may want to drink less or choose a type of drink with fewer calories in.
Alcohol and carbohydrates
If you’re carb counting, drinking can make it a lot more tricky. While a lot of alcoholic drinks contain carbs, you might not need to take your usual amount of insulin to cover them. That’s because you’re more likely to get hypos.
It all depends on what you drink, how much you drink, and what else you’re doing while you’re drinking – like eating or dancing. So it’s best to talk to your healthcare team and get their advice.
The morning after you’ve been drinking
If you end up having one too many, drinking a pint of water before you go to bed will help keep you hydrated. If you’re lucky, it may also help prevent a hangover in the morning. If you do wake up with a hangover, it’ll still help to drink plenty of water.
And always have breakfast – it will help you manage your blood sugar. If you can’t face food or you’ve been sick, drink as many fluids as you can, including some sugary (non-diet) drinks.
If you’ve got a blood sugar meter at home, check your levels regularly the next day. The symptoms of having a hypo are similar to feelings of a hangover, so you need to know if you’re having one. No matter how awful you feel, you need to treat a hypo straight away. Don’t ignore it.
If you take insulin, you might need to change your dose depending on what your levels are. Talk to your healthcare team about what you should be doing.
Types of drinks
If you're going to drink, it's good to be aware of all the facts so you can choose the types of drinks best for you:
- Avoid low-sugar beers and cider – sometimes called diabetic drinks. They might have less sugar, but there's more alcohol in them. Just one pint of a low-sugar beer can bring you above the legal limit.
- Avoid low-alcohol wines – these often have more sugar than normal ones. If you do choose these, just stick to a glass or two. Try to limit drinks with a lot of sugar, such as sweet sherries, sweet wines and liqueurs.
- Have diet or sugar-free mixers with any spirits – if a friend gets one for you, make it clear what you need.
- Some drinks like beers, ales and ciders contain carbs and will increase your blood sugar levels. Spirits, dry wines and Prosecco not so much, so these may be a better bet.
Other health risks
If you have diabetes, you should be aware of the other health risks around drinking. That way, you can help to avoid them by limiting how much you drink.
Here are a few things to watch out for:
- A lot of heavy drinking can lead to raised blood pressure.
- Alcohol can make neuropathy (nerve damage) worse.
- It dehydrates your body and stops you sleeping properly.
- It can also lead to certain cancers and heart disease.
Alcohol and your emotions
Some people find that alcohol helps them deal with stress or when they're feeling low. It might make you feel more relaxed, but it’s not a healthy way of managing these feelings.
Getting more active can really help if you’re stressed or feeling anxious. Starting a hobby with a friend, or doing something relaxing like having a long bath or reading a book can all help.
You can talk to your healthcare team about how you're feeling, they'll be able to give you more advice and support about what might help. Or you might prefer to talk to someone close to you, like a friend or family member.
