dreamstimefree_3765538-1024x684Physical activity can affect your blood glucose for up to 12 hours. When getting started, check your blood glucose just before and right after your activity, as well as several hours after your activity stops.

It is a great way to see the benefit of physical activity. It also helps you watch for any potential low blood glucose levels if you are at risk.

If you take medication that increases insulin release, or you take insulin injections, take a snack along in case your blood glucose runs low.


Discuss some healthy snack ideas with your diabetes educator.

Review low blood glucose levels with your educator to find out if you are at risk and, if you are, always carry glucose tablets with you in case your blood glucose drops too low.

  • Drink plenty of water.
  • Set realistic goals – begin gradually and work at your own preplanned pace.
  • Try to be physically active on a regular basis to establish a comfortable routine.
  • Make sure your shoes fit well and that you replace them on a regular basis.
  • Wear medical identification – it will speak for you when you can’t.

Don’t Exercise If…

  • Your doctor advises against it.
  • You are nauseated or have abdominal pain.
  • Your blood glucose is less than 4 mmols, until you have a snack and your reading returns to normal.
  • Your morning or pre-meal blood glucose is above 14 mmols, and there are ketones in your urine.
  • There are extreme weather conditions. This includes too hot or too cold temperatures, excessive humidity and pollution allerts. Take a look at the forecast and adjust and change your activity to something you can do indoors if possible.
