What Causes Blood Glucose to Go Down or Up During Exercise

By Sheri Colberg, PhD

For all the time that I spend praising the “miracle” of being physically active to help better manage diabetes and health, there are times when exercising does lead to better managed blood glucose and times when it does not. It is not always possible to predict the glycemic outcomes in all cases either, although individual patterns and responses can be determined over time. It is helpful to know the main factors that are predictive of outcomes.

Stay Hydrated Without Overhydrating for Exercise

by Sheri R. Colberg, PhD
Adequate fluid intake is essential to living well at any age, and being dehydrated can impact your health and your athletic endeavors. While it is harder to stay hydrated when exercising in the heat, you can dehydrate under other conditions—even during exercise in cold temperatures if you wear lots of clothing and sweat underneath it. As people grow older, they also begin to lose some of their normal thirst sensations, thereby increasing the risk for dehydration unless they make a conscious effort to drink more.

Debunking Some Physical Activity and Training Myths

How often have you heard things about physical activity and exercise training that you thought sounded correct, but found out later they were totally wrong? If you hang out at a gym or even talk with training coaches, you’ll hear about everything, including contradictory statements about how to be active the right way. Should you work out in a “fat burning” range? Is weight training going to make you bulk up? Will your muscles turn to fat if you stop working out? Do you need to eat a lot more protein to get bigger muscles? Confused? Here is the truth about some of the more common myths you’ll hear about being active.

Interpretation and Management of Hyperglycemia and Exercise

By Sheri R. Colberg, PhD, FACSM
In some circumstances, elevated blood glucose levels can be indicative of medical concerns like insulin deficiency. People with type 1 diabetes are more susceptible to insulin deficiency since they have almost no ability to produce any insulin; therefore, they need to receive instruction on why and when to check for ketones. This is especially important if the individual is using an insulin pump. If ketones are present, then the higher blood glucose levels are a result of insulin deficiency, and corrective action should be taken immediately.

Can You Benefit from Using Exercise Technologies and Wearable Devices?

By Sheri R. Colberg, PhD, FACSM
What do you do when someone asks you to participate in a physical activity on the spur of the moment, but you just took some insulin? You may be stuck trying to compensate for this activity entirely with food, but you may have some newer options that come from technology. For starters, if you wear a pump you can choose to lower your basal insulin delivery, and you can use its insulin-on-board calculator to see how much insulin you need to offset with either insulin reductions or food intake. However, just using your blood glucose meter can help you stay on top of your glucose levels, so check often during the activity.
