Wegovy and alcohol

Wegovy is an effective and popular weight loss injection, but many people wonder if it’s safe to combine Wegovy with alcohol and what effects this could have.

In this guide, we have gathered information based on the latest research on whether you can still enjoy a drink while taking Wegovy, the potential implications, and whether Wegovy can actually help you manage alcohol cravings.

What is Wegovy?

Wegovy is a weekly weight loss injection that contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist.

It works by mimicking the effects of GLP-1, a naturally occurring hormone that suppresses appetite, slows down digestion, and helps the body use insulin more effectively. In doing so, Wegovy can boost weight loss and better manage type 2 diabetes.

Clinical trials have shown that Wegovy can help people lose, on average, 21% of their starting body weight at the maximum maintenance dose of 7.2mg per week. It’s a prescription-only medication, which means you need a doctor's approval to get it, either on the NHS if eligible, or with a private prescription from a clinic, pharmacy, or online doctor service like ZAVA.

How does alcohol affect your weight?

Alcohol can affect your weight in several ways, such as by:

  • adding empty calories to your diet
  • impacting your metabolism (how quickly you break down food to use as energy)
  • affecting your body’s ability to burn fat
  • increasing fat storage, especially around your stomach

Alcohol can also make you feel hungry, leading you to crave unhealthy food. Clinical data suggests that the chance of obesity is 70% higher in people who drink heavily compared to those who are light drinkers. Let’s take a closer look at the impact of alcohol on your weight:

Adds empty calories to your diet

Alcohol has a high calorie content, around 7 calories per gram, which is almost double the amount in protein and carbohydrates. When you’re losing weight, being in a calorie deficit (burning more calories than you consume) is essential. Alcohol can add calories to your diet without giving you any nutritional benefit, and can put you in a calorie surplus rather than a deficit, stalling your progress or causing weight gain.

clock

Slows down body's fat-burning process

When you drink alcohol, your body recognises it as a toxin and prioritises its metabolism over other nutrients like fats and carbohydrates, which are needed for energy. In doing so, the body burns less fat for energy, leading to increased fat storage.

Earlier research suggested that moderate alcohol consumption is linked to abdominal visceral fat in healthy women. More recent research has shown that heavy alcohol intake across both men and women was linked to a 15.1% increase in fat around the heart, 3.4% liver fat, and 2.5% visceral fat storage compared to non-drinkers.

Can you drink alcohol when taking Wegovy?

Yes, you can drink alcohol in moderation while taking Wegovy, but it’s not advisable as it can make the side effects worse and hinder your weight loss goals.

What happens if you drink alcohol on Wegovy?

Although there are no direct interactions from mixing Wegovy with alcohol, mixing them can:

  • cause side effects to get worse, particularly feeling or being sick, and stomach pains
  • reduce your blood sugar levels because as your liver processes alcohol, it stops the release of glucose, which can be made worse by Wegovy as it also lowers glucose levels
  • increase the chance of dehydration because alcohol causes you to pee more, while the side effects of both alcohol and Wegovy, particularly vomiting and diarrhoea, also cause fluid loss
  • make you choose less healthy foods or prompt you to eat more than you usually do, which may affect your weight loss progress on Wegovy

Different people respond to alcohol and Wegovy differently, so it’s important to monitor how your body reacts to help you stay on track with your treatment. You may even be advised to limit or cut your alcohol intake to hit your weight loss targets.

Does alcohol make Wegovy less effective?

No, there is no direct evidence that alcohol makes Wegovy less effective, but it can negatively impact your weight loss progress by adding extra calories to your diet or causing unhealthier choices. This does not stop the medication from working, but you are likely to see less weight loss if you have high-calorie drinks often.

Does Wegovy help with alcohol cravings?

Potentially. New research suggests that once-weekly semaglutide (Wegovy) injections significantly reduced the number of alcoholic drinks consumed on a drinking day by 41% and lowered weekly alcohol cravings by almost 40% over 9 weeks.

This research is promising because it shows that even low doses of semaglutide (0.25mg for 4 weeks, 0.5mg for 4 weeks, and 1mg for 1 week) can reduce alcohol cravings and the amount of alcohol consumed. However, further research is needed, as this study was relatively small, involving only 48 participants.

Does Wegovy affect alcohol tolerance?

Yes, because Wegovy slows down how quickly food leaves your stomach, it can lead to alcohol being absorbed more slowly into your bloodstream and over a longer period of time. This means that for some, you may feel the effects of alcohol much more quickly and strongly than you used to, or it may have the opposite effect, and you may not feel the same ‘buzz’ as you did before. Some people also report ‘less desire’ for alcohol since starting Wegovy.”

Wegovy and alcohol side effects

There is no direct interaction between alcohol and Wegovy, but combining them can intensify the gastrointestinal side effects associated with Wegovy, such as:

  • feeling sick
  • being sick
  • stomach pains

Alcohol and Wegovy also increase the chance of dehydration, headaches, and fatigue, so mixing them may cause these effects to get worse, especially if you already have vomiting or diarrhoea. If you get dizzy on Wegovy, it is possible that drinking alcohol may also make this worse.

Can alcohol make Wegovy side effects more likely?

If you are already experiencing Wegovy side effects, drinking alcohol at the same time can make them worse. Equally, alcohol can cause its own side effects, which are similar to Wegovy’s, particularly if you drink heavily or on an empty stomach.

In conclusion: Should I drink alcohol when taking Wegovy?

Although you can drink alcohol on Wegovy, it is important that you do so in moderation. There is no evidence that alcohol directly interferes with the way Wegovy works, and it is not listed as something to avoid in the patient information leaflet. For most people, the occasional drink will not affect how the medication works.

However, alcohol adds extra calories and can increase cravings for particular food choices. This means it can slow your weight loss progress, even if the medication continues to help control your appetite.

Alcohol can also make Wegovy side effects worse, like feeling or being sick, dizziness, and stomach upsets. Drinking alcohol in large amounts or on an empty stomach can worsen these issues and increase the likelihood of feeling unwell.

Overall, drinking small amounts of alcohol occasionally will be fine for most people on Wegovy. If you do get side effects, try avoiding alcohol until you feel better. Heavy or frequent drinking could slow your weight loss and increase the severity of side effects. Your doctor can give you further advice about how alcohol fits into your treatment plan, and what a safe level of drinking looks like if you are concerned.
