Glucagon in Hypoglycemia Treatment: How It Safely Raises Blood Sugar Levels

Hypoglycemia, often referred to as low blood sugar, is a common concern for individuals with diabetes, especially those using insulin or certain oral medications. When blood sugar levels drop dangerously low, it can lead to symptoms ranging from mild discomfort to severe impairment. In such situations, healthcare providers, including nurses, have an important tool at their disposal: glucagon. Glucagon is a hormone that can be administered to rapidly raise blood sugar levels and alleviate the effects of hypoglycemia. In this article, we will explore why and how nurses use glucagon in the treatment of hypoglycemia.

Understanding Hypoglycemia:

Hypoglycemia occurs when blood sugar levels fall below the normal range, typically below 70 milligrams per deciliter (mg/dL). It can result from various factors, including:

  1. Excessive insulin: Taking too much insulin can cause a rapid drop in blood sugar levels.
  2. Delayed or missed meals: Not eating on time or skipping meals can lead to low blood sugar.
  3. Increased physical activity: Intense exercise can cause the body to use glucose more quickly, leading to hypoglycemia.
  4. Alcohol consumption: Alcohol can interfere with the liver’s ability to release stored glucose, increasing the risk of hypoglycemia.

The Role of Glucagon:

Glucagon is a hormone produced by the alpha cells in the pancreas, the same organ that produces insulin. While insulin lowers blood sugar by promoting glucose uptake into cells, glucagon has the opposite effect. When blood sugar levels drop too low, the body releases glucagon, which signals the liver to break down stored glycogen into glucose and release it into the bloodstream. This process helps raise blood sugar levels to a safe range.

Administering Glucagon in Hypoglycemia:

In some cases, individuals with diabetes may experience severe hypoglycemia, rendering them unable to consume oral carbohydrates to raise their blood sugar. This is where glucagon comes into play. Glucagon can be administered as an injection to quickly raise blood sugar levels. Here’s how nurses use glucagon in the treatment of hypoglycemia:

  1. Assessment: The nurse assesses the client’s condition, looking for symptoms of severe hypoglycemia, such as confusion, unconsciousness, or seizures.
  2. Preparation: The nurse prepares the glucagon injection, typically in a prepackaged kit that includes a vial of powdered glucagon and a syringe with a diluent.
  3. Reconstitution: The nurse reconstitutes the glucagon by mixing the powdered glucagon with the diluent, following the package instructions.
  4. Injection: The nurse administers the glucagon injection, usually into the client’s thigh, buttock, or arm muscle. The injection stimulates the liver to release stored glucose, rapidly raising blood sugar levels.
  5. Monitoring: After administration, the nurse monitors the client’s response, ensuring that their blood sugar levels return to a safe range.

Why Glucagon Is Used:

Nurses and healthcare providers use glucagon in the treatment of hypoglycemia because it provides a rapid and effective means of raising blood sugar levels, especially in cases where the client cannot consume oral carbohydrates due to severe symptoms or unconsciousness.


In the management of hypoglycemia, nurses play a crucial role in administering glucagon when necessary. This hormone safely and effectively raises blood sugar levels, helping individuals with diabetes recover from severe episodes of low blood sugar. Understanding the mechanism of glucagon and its role in hypoglycemia treatment is essential for nurses to provide prompt and appropriate care to their clients, ensuring their well-being and safety in challenging situations.
