Life with a pump

Diabetes and alcohol

For many people, having diabetes does not stop them from living a healthy and active lifestyle. Whether it is going out with friends, grabbing a bite to eat or enjoying the occasional alcoholic drink, it is important to be prepared and proactive when it comes to diabetes management.

When it comes to alcohol, it is important to recognize the effects it can have on glucose levels to better understand the body’s insulin and carbohydrate needs when drinking.

Some alcoholic drinks contain quite a lot of sugar which makes it difficult to maintain good blood glucose levels. So, when I was on multiple daily injections, I had to give myself an extra injection or choose not to drink with my friends. The side effects of the alcohol can also hide the symptoms of a hypo. My insulin pump makes it possible to enjoy a few drinks with my friends while staying in control.


Keeping blood glucose levels under control

After eating, food is broken down into glucose which is needed to give the body energy for all daily activities. Our bodies also need insulin, normally produced by the pancreas, to help transfer glucose from the bloodstream to the cells.

When the pancreas does not produce insulin the glucose will remain in the blood, leaving cells without any energy. These high glucose levels in the blood cause the more acute clinical signs and symptoms of diabetes. To treat diabetes it is important to take into consideration many factors in its management, including blood glucose monitoring, carbohydrate intake, physical activities and insulin requirements to ensure good blood glucose control and to reduce the risk of complications.

Alcohol can alter blood glucose levels, or potentially increase the risk of hypoglycaemia. It is important to understand the amount of carbohydrates in each drink, as this can vary depending on alcohol type and mix. It is important to monitor glucose levels before, during and after drinking alcohol.

Hypoglycaemia (“hypos”) refers to when blood glucose levels fall below 3.5 mmol/L, although the exact figure can vary between individuals. In the case of mild hypoglycaemia, symptoms are felt, and action can be taken to prevent it becoming worse by eating or drinking something containing carbohydrates. Severe hypoglycaemia requires assistance from another person and may need hospital treatment.

It can be a challenge to reach and maintain the HbA1C goal whilst minimising the risk of hypoglycaemia. However, by understanding the body’s needs and learning how to keep blood glucose within recommended levels, it is possible to manage diabetes effectively.

HbA1c: an important measure of how effectively diabetes is being managed using a measure of the amount of glucose that has attached itself to each red blood cell over the preceding 2 to 3 months to assess the level of diabetes control.

So, as someone living with Type 1 diabetes, how can I better manage my glucose levels whilst drinking alcohol?

Diabetes, alcohol & insulin pumps

To deal with the challenges of keeping blood glucose levels under better control, many people with Type 1 diabetes rely on insulin pumps.

An insulin pump is a small device, about the size of a mobile phone, that can be easily carried on a belt, inside a pocket, or even attached to a bra.

An insulin pump can help you and your healthcare team to more closely mimic the way a healthy pancreas delivers the basal insulin to the body by providing small amounts of rapid acting insulin during the day and night. It can help to better manage the need for insulin dose adjustment, particularly after meals and overnight and can thus help to achieve better glucose control.

Instead of frequent injections, all that is needed on pump therapy is a change of infusion set every few days. Clinical studies*confirm that many Type 1 patients of various ages who switch from MDI to insulin pump therapy report improvements in their quality of life and increased satisfaction with their treatment.

Without the pump, I would have preferred not to drink rather than to add an extra injection in the evening. Now, however, with the pump, nothing is really off limits to me.


Minimed 640G insulin pump on adult's body


The MiniMed® 640G insulin pump allows for better glucose control due to the ability to adjust insulin delivery, reducing the risks of hypers and hypos. With insulin pump therapy users can benefit from:

  • Easier dosing
    Calculating insulin requirement can be a complex task with many different aspects to be considered. As part of the MiniMed 640G insulin pump, the built-in Bolus Wizard® feature helps to ensure more accurate dosing by taking into account the insulin already in the body, current glucose levels, carbohydrate intake and personal insulin settings.
  • Fewer injections
    Precise amounts of rapid acting insulin are delivered throughout the day by the infusion set which is easily removed and replaced every 2 to 3 days.
  • Greater flexibility
    The MiniMed 640G insulin pump can be instantly adjusted to allow for exercise, during illness or to deliver small boluses to cover snacks. This can be easily done with a touch of a button, rather than with another injection. There is even a temporary basal rate option to proportionally reduce the basal insulin rate, an option that can be used during exercise, for example.
  • More convenience
    The MiniMed 640G insulin pump offers the additional convenience of a wirelessly connected blood glucose meter. This meter automatically sends blood glucose values to the pump, allowing more accurate Bolus Wizard calculations. It also stores this information in a digital diary along with your insulin doses.


Many people with Type 1 diabetes may benefit from an insulin pump without even knowing it. In general if you experience any of the following, you could get better control with an insulin pump:

  • Concerns about long-term complications
  • The first symptoms of long term complications
  • Fear of needles
  • Difficulty in managing highs and lows
  • Fear of hypoglycaemia, especially at night
  • Outside targeted HbA1c levels
  • Reduced hypoglycaemia awareness
  • Seeking more flexibility in everyday life

The best way to stay within a healthy glucose range is to self-monitor blood glucose (SMBG) at least 4 times per day and make adjustments to the therapy as needed. The MiniMed 640G insulin pump with the use of the Bolus Wizard can make these calculations and adjustments to help improve glucose control.


The MiniMed 640G insulin pump is also available with the additional integrated options of continuous glucose monitoring (CGM) and CareLink Therapy Management Software.

When coupled with CGM, the MiniMed 640G insulin pump is currently the only insulin pump with the SmartGuard® feature which may help reduce the impact of hypoglycaemia*. If glucose levels fall dangerously low, SmartGuard can predict when you are approaching lows 30 minutes in advance and automatically stop insulin delivery. When your glucose levels recover, it will automatically resume insulin delivery. This could be a big advantage over SMBG because the MiniMed Integrated System alerts you prior to crossing pre-set threshold limits, as well as showing current glucose trends.
