Avoid alcohol in type 1 diabetes

People with type 1 diabetes who drink alcohol should have a low-to-moderate alcohol intake; i.e. no more than two standard drinks per day. (The Australian Government Department of Health and Ageing explains what is meant by an Australian Standard Drink.) A health professional can provide more advice about this.

Alcohol decreases the amount of blood glucose, and increases the chance of low glucose levels (hypoglycaemia or ‘hypos’). This is because the body, especially the liver, needs to break down the alcohol, and while it is processing the alcohol, the liver won’t release any glucose into the blood. This can lead to very low blood glucose levels.
