Insulin Before Exercise May Be Needed to Lower Morning Highs

Diabetes in Control has a lessons learned section for health professionals. Although we commonly think of exercise that will lower our blood sugars some insulin users find the opposite occurs. This is the case report.


A man with type 1 diabetes started an exercise program to help him manage his early morning highs. He exercised every evening, at which time his glucose levels would drop during and after exercise. Thinking that exercise would lower his early morning highs, he did not take his insulin before exercise. He was surprised to see his glucose would go up after exercise rather than go down….

He discussed this with his endocrinologist who recommended he take a very small amount of fast- or rapid-acting insulin before exercise. His glucose levels did well. He was surprised to see his levels did not get low, nor were they high after exercise anymore. This became his regular regime.

Lesson Learned:
•Even though exercise makes an individual more insulin sensitive, one still needs insulin for muscles to use glucose. Without enough insulin, glucose levels can rise.
•Individuals can and usually do have different insulin needs throughout the day.
•To lower post-exercise highs, start low and go slow to learn the amount of insulin your patient needs. Some need only one unit.
•Check before, during, and after exercise, or better yet, use CGM and track trends.

Seven Free Online Work-Outs for You To Try

From bootcamps to ballet, there's a work-out for everyone on YouTube.
From bootcamps to ballet, there’s a work-out for everyone on YouTube.

When I first got into fitness some 25 years ago, there were nothing like as many options as there are now. I do remember doing one of Cindy Crawford’s original exercise videos (it was awful) and cycling everywhere.

Nowadays though, there are so many choices if you want to get more active but you don’t want to, or can’t afford to, join a gym or attend classes.

Step forward YouTube! If you know where to look, you can access thousands of online exercise DVDs so you never need to pay for anything (apart from your broadband connection of course) or leave the comfort of your own home.

The videos vary greatly in quality of course – from really slick, professionally produced clips to the rather more amateur, and length varies too. Some of the moves and programmes will be demonstrated very well, others will be downright dangerous – but intelligent adults need to work this out by themselves, recognising that free stuff doesn’t come with the same checks and balances you can expect if you pay for gym memberships, classes or personal training.

It’s important to exercise whether you have type 1 or type 2 diabetes because exercise increases your sensitivity to insulin, and it reduces the risk of cardio vascular disease (people with diabetes have an increased risk of CV disease). Continue reading “Seven Free Online Work-Outs for You To Try”
