Managing Alcohol and Diabetes: Tips for Safe Drinking During the Holidays

Family gatherings, events and festivities during the holiday or weekend period usually involve various types of food and alcohol. This can make monitoring diabetes and blood glucose levels more difficult.

Drinking alcohol while managing diabetes presents unique challenges, as alcohol can have complex effects on blood glucose levels and overall health. Here are some key challenges to consider:

1. Blood Glucose Fluctuations

• Alcohol impacts blood glucose in unpredictable ways. It can initially cause a spike if the drink contains sugar, but it may lead to hypoglycaemia (low blood glucose) hours later. This delayed drop happens because the liver prioritises metabolising alcohol over producing glucose, which it normally releases to maintain blood glucose levels.
• The risk of hypoglycaemia is particularly high when drinking on an empty stomach, engaging in physical activity, or consuming alcohol without carbohydrates.

2. Difficulties in Recognising Hypoglycaemia

• Hypoglycaemia symptoms—such as dizziness, confusion, and shakiness—can easily be mistaken for intoxication, making it harder to recognise low blood glucose. This overlap can delay critical actions needed to raise blood glucose levels, putting individuals at risk for severe hypoglycaemia if left unaddressed.

3. Compromised Judgement and Decision-Making

• Alcohol impairs judgement and decision-making, which can make it challenging to stay on top of diabetes management tasks, like checking blood glucose, eating appropriately, or remembering insulin dosages. This can lead to decisions that might jeopardise health, such as neglecting to monitor blood glucose or forgetting to eat when needed.

4. Increased Risk of Dehydration

• Alcohol is dehydrating, and dehydration can lead to high blood glucose levels. For people with diabetes, hydration is critical, as even mild dehydration can cause blood glucose to become more concentrated. The diuretic effect of alcohol can further complicate this, leading to fluctuations that are harder to control.

5. Interactions with Medications

• Alcohol may interact with diabetes medications, particularly insulin and sulfonylureas, which can increase the risk of hypoglycaemia. It’s essential for people on medication to understand how alcohol may alter its effectiveness and to adjust accordingly by eating or checking blood glucose more frequently.

6. Social Situations and Peer Pressure

• Social events where alcohol is present often come with peer pressure or a desire to fit in. This can lead to overindulging or drinking without careful planning. For people managing diabetes, these social pressures add a layer of complexity to safely navigating alcohol consumption.

7. Long-Term Health Risks

• Excessive or frequent alcohol consumption can increase the risk of complications related to diabetes, such as liver disease, heart disease, and neuropathy. Drinking with diabetes requires a cautious approach to avoid both immediate and long-term health consequences.

Here are five key tips for drinking alcohol when managing diabetes:

1. Check Your Blood Sugar Levels Regularly
   Alcohol can affect blood sugar levels in unpredictable ways, sometimes lowering them hours after drinking. Monitor your blood sugar before, during, and after drinking to stay aware of any changes and prevent hypoglycemia.

2. Eat Before or While Drinking
   Drinking on an empty stomach can increase the risk of low blood sugar. Have a balanced meal or snack that includes protein, fat, and carbs to help keep your blood glucose stable.

3. Choose Lower-Carb Drinks
   Opt for drinks that are lower in sugar, such as dry wines, light beers, or spirits mixed with sugar-free options. Be cautious with cocktails or sweetened mixers that can cause spikes in blood glucose.

4. Stay Hydrated
   Alcohol can dehydrate you, which can complicate blood sugar management. Drink water in between alcoholic drinks to stay hydrated and reduce the overall amount of alcohol you consume.

5. Wear Medical Identification
   Always carry medical identification, such as a diabetes bracelet, especially if you’re out celebrating. If your blood sugar drops, people around you will be informed of your condition and can help if needed.
