Glucagon

Introduction

Glucagon is a naturally occurring hormone and an important emergency medicine used mainly to treat severe low blood sugar (hypoglycemia). It is especially helpful for people with diabetes who use insulin and may experience sudden drops in blood glucose levels. Glucagon works quickly to raise blood sugar when a person is unconscious or unable to take sugar by mouth. Apart from emergency use, it is also used in certain diagnostic tests to relax the muscles of the stomach and intestines. Glucagon is available as an injection or nasal spray and should be used under medical guidance.

Uses of Glucagon

• Treatment of severe hypoglycemia in diabetic patients
• Emergency use when a patient is unconscious due to low blood sugar
• Used during diagnostic imaging of the stomach and intestines
• Helps relax gastrointestinal muscles for medical procedures

How Glucagon Works

Glucagon works by stimulating the liver to convert stored glycogen into glucose and release it into the bloodstream. This rapid increase in blood sugar levels helps reverse the symptoms of severe hypoglycemia. It acts opposite to insulin and is especially effective when oral glucose cannot be given. Its action begins within minutes after administration.

Benefits of Glucagon

• Rapidly increases dangerously low blood sugar levels
• Life-saving in emergency hypoglycemia situations
• Easy to administer as injection or nasal spray
• Useful in medical diagnostic procedures

How to Take Glucagon

Glucagon should be used exactly as prescribed by a doctor. In emergencies, it is usually given as an injection into the muscle or under the skin, or as a nasal spray. Once the patient regains consciousness, oral glucose or food should be given. Always seek medical help after use.
