What are the risks?
- Gut: Alcohol irritates the stomach and worsens nausea and reflux, which are common on GLP-1 medications anyway
- Pancreas: Heavy drinking is a risk factor for pancreatitis – a rare but serious possible side effect of these medications
- Low blood sugar: Especially if you also take insulin or sulfonylureas
- Empty calories: Alcohol contains a lot of energy and inhibits fat burning
Why do many people feel less like drinking?
GLP-1 receptors are also found in the brain’s reward system. Many users report having less craving for alcohol. Whether GLP-1 medications help against alcohol dependence is currently being investigated in studies – they are not approved for this.
If you do drink
- Little and slowly, never on an empty stomach
- Drink water in between
- Not in the days after a dose increase
- If you take diabetes medication: keep an eye on your blood sugar
When to see a doctor
- Severe upper abdominal pain radiating to the back
- Persistent vomiting
- Signs of low blood sugar: trembling, sweating, confusion
In an emergency: 112.
