Hypoglycemia and Outdoor Activities
Hypoglycemia is a term to describe low blood sugar. For people with diabetes, blood sugar below 70 mg/dl is considered to be hypoglycemia. This can be caused in various ways — physical activity, mismatching insulin with carbs, going long periods of time without food or without carb-containing foods, and more. Hypoglycemia can happen at any time, especially if you’re enjoying outdoor activities. Severe hypoglycemia may manifest itself as lightheadedness, confusion, or dizziness, shaking, seizures, or unconsciousness. If not treated in time or properly, it can be fatal.
The hypoglycemic effects of sports and exercise can be hard to notice because of the increased adrenaline produced during physical activity. Also, as the weather gets warmer and you’re more active outdoors, the symptoms of hypoglycemia may mimic the body’s response to heat and also make it hard to identify hypoglycemia as it happens.
We know you have a life, and if you’re reading this, you probably like to go out and enjoy outdoor activities. The focus of this article is on how to prevent and treat hypoglycemia when you’re playing sports, hiking, camping, or whatever fun activity you love.
Before starting your new activity:
- Check your blood sugar – if your blood sugar is already low, wait until it rises to normal levels.
- Pack glucose tablets, drinks, or snacks to act as a fast carbohydrate.
- Keep extra test strips and lancets or set alerts on your CGM device to notify you of low blood sugar.
- Tell your emergency contact where you are and what you’re doing. Set up check-ins if your activity is considerably strenuous or if you’re going to a relatively remote location.
If necessary, contact your doctor to inquire about other medications you should bring with you, such as Glucagon.
- Check your blood sugar regularly and adjust the intensity of your activity as needed.
- Adjust insulin dosages (basal or bolus insulin) as needed or as prescribed by your doctor.
- Remain energized with snacks + drinks to prevent lows.
- Keep track of your diabetes supplies and make sure they’re stored at temperatures according to the manufacturer’s instructions.
- Take a break or stop if you begin to feel the symptoms of hypoglycemia.
In the event you check your blood sugar or feel the signs of severe hypoglycemia, and are unable to ingest carbs or your blood sugar is not increasing with carbs consider using Glucagon. Glucagon is available as an injectable or as a dry nasal spray, called Baqsimi, that can be administered by another person in an emergency situation. In an emergency, call 911 if you feel the symptoms of severe hypoglycemia and keep a disaster preparedness plan or kit with you. Alert others where your Glucagon is stored, too, and know how to use it in an emergency situation.
What if I’m Traveling?
While this article focuses on outdoor activities, it’s important to know about low blood sugar while traveling abroad. Hypoglycemia occurs in up to 10 percent of people with diabetes who are insulin-dependent during travel abroad or within the first 24 hours after arriving in a new location. Possible reasons for include changes to your diet, changes or incorrect adjustments to insulin dosages and timing. For people with insulin pumps, changes in air pressure can affect insulin delivery.
You can bring diabetes supplies through TSA to be screened. However, before you go through the security checkpoint, you’d want to notify the agent you’re carrying medical supplies. Also, you’d want to keep your Glucagon, or glucose tablets, with you and not in checked baggage just in case you have an emergency on the plane — most major airlines do not have glucagon available
