Insulin Types

PD Medicine and Healthcare MHE 046 Insulin is a hormone in the body that helps control glucose levels in the blood. It helps transport glucose from the bloodstream to the cells for energy. Glucose is needed by all cells to perform their functions.

People with type 1 diabetes are unable to make insulin. While those with type 2 diabetes can make insulin, the body is resistant to it and unable to use it appropriately. As a result, glucose builds up in the bloodstream and the cells become starved, which can lead to serious health problems.

Insulin Shots

If you have diabetes, you may need to take insulin shots to make up for your body’s inability to make or use naturally occurring insulin. You may need anywhere from 1-4 shots a day. The medication may also be given using a special injector pen or pump.

How much insulin you need depends on several factors, such as your:

  • Residual insulin production
  • Body weight
  • Body fat percentage
  • Physical activity level
  • Diet
  • Other medications that you take
  • Emotional health, including your level of stress
  • Overall health
