Are you a teacher or school nurse who has wondered how you can help your students with diabetes feel their best at school? Low blood sugar episodes at school can affect a student with diabetes’ ability to learn, concentrate, and participate in activities.
School staff needs to recognize and respond to low blood sugar to ensure a safe learning environment for students with diabetes. By the end of this blog post, you’ll have the knowledge and tools needed to confidently support students with diabetes and their well-being at school.
Teachers and nurses should understand why blood sugar levels can become too low, a condition called hypoglycemia, as it is the greatest immediate danger to students with diabetes.
Here are some reasons why students might have a low blood sugar episode:
Insulin is a medication that helps people with diabetes manage their blood sugar levels. Students may take too much insulin by accident or even due to a slight miscalculation. This can make their blood sugar levels drop too low.
Even though schools have set times for eating, sometimes students might not eat during their usual timeframe. If they skip meals or snacks or eat them later than they’re supposed to, their blood sugar levels can drop too low.
Students may participate in more exercise or activity than usual, like during gym class, recess or walking between classes. Extra or unplanned activities can use up a lot of extra energy or glucose in their bloodstream. If a student did not adjust their insulin or eat enough food, their blood sugar levels can drop too low.
If a student takes insulin but doesn’t eat enough carbohydrates to match their insulin dose, there won’t be enough glucose in the bloodstream to balance out the insulin. This can cause blood sugar levels to drop too low.
During a low blood sugar episode at school, students may display various symptoms, which can vary depending on how severe the episode is. Teachers and nurses need to recognize these symptoms and take action to treat a low blood sugar episode promptly to keep students safe and healthy at school.
When blood sugar levels are mildly or moderately low, typically falling between 70 mg/dL and 54 mg/dL, teachers may notice changes in the student’s behavior, such as acting irritable, confused, or having trouble concentrating.
Students may also experience physical changes like sweating, looking pale, shakiness, or tiredness. Other symptoms might include complaints of headache, a fast heartbeat, weakness or feeling nauseous.
When blood sugar levels drop below 54 mg/dL, indicating a severe low blood sugar episode, students may experience more serious and potentially dangerous symptoms. These can include a loss of coordination, difficulty staying conscious, being unable to swallow properly, having seizures, or being unresponsive to others.
Low blood sugar episodes can usually be treated easily and effectively by providing the student with fast-acting carbohydrates to bring glucose levels back into a safe range.
It is best to try to stop low blood sugars before they happen, but it isn’t always possible. If a low blood sugar episode does happen, it should be fixed quickly because students can lose consciousness and they can become life-threatening when left untreated.
Below are the generally accepted approaches for the treatment of low blood sugar, but each student’s specific treatment plan will be given to the school.
If a student is experiencing mild to moderate low blood sugar, they might need 7-15 grams of fast-acting carbohydrates, such as glucose gel or glucose shots. The exact treatment will be outlined in the student’s emergency care plan. After 15 minutes, their blood sugar should be checked again to see if additional fast-acting carbohydrates are needed.
Severe low blood sugars are rare and generally can be prevented with prompt treatment of mild to moderate low blood sugars. When low blood sugars become severe, school nurses or trained diabetes personnel must be notified and respond immediately.
Severe low blood sugar episodes can lead to unconsciousness and disrupt the student’s ability to swallow. School personnel should never attempt to give the student food or drink by mouth when unconscious because it can cause choking.
Severe low blood sugar episodes should be treated by administering glucagon by injection or dry nasal spray. Glucagon is a life-saving hormonal treatment that raises glucose levels by causing the release of glycogen from the liver.
The school nurse and/or trained diabetes personnel must know where the student’s glucagon emergency kit is stored, have access to it at all times, and be familiar with the glucagon administration instructions before an emergency arises.
If a low blood sugar episode goes untreated at school, it can pose a significant risk to the health, safety and well-being of students with diabetes. The potential risks include:
Preventing low blood sugar episodes in students with diabetes at school requires collaboration between school personnel, school nurses, parent/guardian, and the students themselves. Here are some ways to work together to prevent or reduce low blood sugar episodes:
