Fat jab customers warned to not overdo the booze this Christmas to keep away from passing out

The weight-loss drugs slow the rate at which alcohol enters the bloodstream, meaning it can take longer to feel the effects of drinking

Folk on fat jabs are being warned not to overdo the booze this Christmas to avoid feeling sick or passing out.

The weight-loss drugs slow the rate at which alcohol enters the bloodstream, meaning it can take longer to feel the effects of drinking, research suggests.

Pharmacist and weight-loss expert, Jason Murphy, warned that slimmers may not feel like they are getting drunk and could be tempted to “overindulge” in festive tipples.

Mr Murphy, from online pharmacy Chemist4U, said: “Alcohol absorption can be slower on GLP-1 medications because weight-loss injections slow the emptying of your stomach, which makes it tricky to judge your limit.

“Overindulging can increase the risk of hangovers as well as worsening common side effects, such as nausea, dizziness or feeling generally unwell, so it’s better to enjoy drinks in moderation or drink less than you usually would. Your body will give you signals if something isn’t right, so if you do start to feel nauseous or unusually tired, then it’s best to stop drinking and rest.”

The chemist said folk on fat jabs could drink alcohol in moderation if their doctor said it was okay. But Mr Murphy said people on drugs such as Wegovy or Mounjaro should pace themselves.

He said: “This helps you enjoy the season safely without any unpleasant surprises. If you often notice more side effects [from alcohol] on your injection day, it might be a good idea to avoid alcohol completely that day.”

Mr Murphy added: “Stay hydrated and snack wisely – alcohol dehydrates you, and GLP-1 medications can sometimes cause nausea as a side effect. If you know you’re going to be drinking, make sure you drink water between alcoholic drinks and remember to eat enough to help maintain your energy levels.

“This will help reduce nausea and keep your blood sugar stable.”
