Insulin is a hormone taken to help control blood sugar. People with type 1 diabetes produce little or no insulin, so they need injections to survive. People with type 2 diabetes can’t use insulin properly and may eventually need it to manage their condition.

Starting an insulin regimen can be life-changing and a little bit scary, but don’t let social stigma and fear-mongering news reports put you off. The truth is that insulin is a safe and effective treatment used by more than 8 million people in the United States to manage their diabetes.

With that in mind, here are some of the most common myths you might hear about insulin, and the truths behind them.
