How does alcohol affect my body?

If you have diabetes, alcohol can affect your body in the following ways:1

Risk of hypoglycaemia (low blood sugar)

Taking certain medications can put you at risk of alcohol-related hypoglycaemia. This can occur while drinking alcohol, or many hours afterwards. Alcohol can also make it harder to recognise and treat hypoglycaemia.

Risk of hyperglycaemia (high blood sugar)

On the other hand, alcohol also puts you at risk of hyperglycaemia. This is because alcoholic drinks contain carbohydrates in different amounts.

Weight gain

Alcohol is high in calories and has very little nutritional value. If you drink alcohol in large amounts, or on a regular basis, it can lead to weight gain.

Damage to your body

Drinking large amounts of alcohol can affect many different parts of the body, and increase your risk of developing heart disease and some cancers.

Risk of diabetes complications

Alcohol can cause weight gain, increased triglycerides (blood fats) and high blood pressure, increasing your risk of developing complications.

How can I drink alcohol safely?

It’s important to remember that alcohol is a drug and there is no safe way to consume it. If you choose to drink, you should limit your intake, especially if you need to manage your weight or lose weight. The less you drink, the lower your risk of alcohol-related harm.1,2
