3 Things to Know When Working with Diabetic Clients

By: Fitness Learning Systems

 

1. Symptoms of Hypoglycemia

Prevention of hypoglycemia is important for a safe exercise program for someone who has diabetes. Anyone taking insulin or an oral medication that may cause hypoglycemia should be aware of symptoms and how to manage this situation especially during exercise. Hypoglycemia occurs when glucose levels are < 70mg/dl. This condition may become worse if not treated. Prevention is the best intervention.

Symptoms may include:

• sweating
• shaking
• dizziness
• headache
• confusion
• irritability
• hunger
• personality change
• weakness
• vision changes
• seizures and/or loss of consciousness.

 

2. Exercise Blood Sugar Guidelines

Blood glucose should be checked and treated if the reading is below 70 mg/dl.

Treatment: It is recommended to follow the “Rule of 15”:

1. 1. Eat 15 grams of carbohydrate, wait 15 minutes, then eat another 15 grams of carbohydrates if there is no improvement in symptoms. (Lobb-Oyos 2012)

When exercising, blood glucose levels should be at least 100-110 mg/dl.

1. 1. If not, a carbohydrate should be consumed and levels can be rechecked before starting to exercise.
   2. Type 1 diabetics using insulin pumps may need to adjust insulin delivery during exercise and basal delivery rates for up to 12 hours post-exercise to avoid hypoglycemia. (ACSM 2013)

 

3. Recommended Pre-Exercise Carbohydrate Intake

 

Pre-Exercise Glucose	Exercise Intensity and Duration	Additional Food Needed
<100 mg/dl	Low (< 30 min) Moderate (30-60 min) Strenuous (> 60 min)	15 grams of carbohydrate 30 grams of carbohydrate 60 grams of carbohydrate
101-170 mg/dl	Low (< 30 min) Moderate (30-60 min) Strenuous (> 60 min)	No additional food necessary 15 grams of carbohydrate 30 grams of carbohydrate
171-300 mg/dl	Low (< 30 min) Moderate (30-60 min) Strenuous (> 60 min)	No additional food necessary No additional food necessary 15 grams of carbohydrate
>300 mg/dl	*Blood sugar needs to be under control prior to starting exercise!

*(Type 1 DM Glucose > 250 mg/dl: Check for ketones; if present, notify physician)
