Glucagon, particularly porcine glucagon, is widely used in medical settings for its ability to raise blood glucose levels. It is commonly administered as an emergency treatment for severe hypoglycemia, especially in diabetic patients who may become unconscious due to extremely low blood sugar. The hormone works by stimulating the liver to convert stored glycogen into glucose, which is then released into the bloodstream. Additionally, porcine glucagon is utilized in diagnostic procedures, such as imaging of the gastrointestinal tract, where it helps relax smooth muscles and slows down bowel movements, allowing for clearer imaging results. It is also employed in the glucagon stimulation test to assess growth hormone production and evaluate pituitary function. Its role in managing insulin-induced hypoglycemia in both clinical and emergency scenarios makes it a critical therapeutic agent.
