Since our family started managing diabetes day to day years ago, I’ve noticed something I never paid attention to before: how often movies and TV get it completely wrong. Not “creative license” wrong. Actually backwards, sometimes dangerously wrong.
The moment that really got me was watching a character pass out from low blood sugar, only for someone to jab them with an insulin shot and have them spring back to life seconds later. My first thought was, wait, really? Because that’s not just inaccurate, it’s the opposite of what should happen.
So here’s what I wish more people understood, myth by myth.
Myth: Insulin fixes a low blood sugar episode
This is the one Hollywood loves most, probably because a needle reads as more dramatic than a juice box. But insulin lowers blood sugar. If someone is already having a low, giving them insulin doesn’t help, it makes things worse, and it can turn a scary moment into a genuinely dangerous one. The real fix is fast acting sugar like juice or glucose tablets, or glucagon in a true emergency. It’s not nearly as cinematic, but it’s what actually works.
Myth: Type 1 and Type 2 are basically the same thing
They get lumped together constantly, on screen and off. Type 1 is an autoimmune condition where the body stops producing insulin at all. Type 2 involves insulin resistance and can sometimes be managed without insulin at all. Treating them as interchangeable, or assuming one caused the other through diet, misses what’s actually going on and adds a layer of judgment nobody needs.
Myth: There are only two types of diabetes
Even people who know Type 1 and Type 2 are different often assume that’s the whole list. It’s not. LADA (Latent Autoimmune Diabetes in Adults), sometimes called type 1.5, is its own thing, a form of autoimmune diabetes that shows up more slowly and later in life than typical Type 1, which means it gets misdiagnosed as Type 2 more often than it should. There’s a lot more nuance here than picking one of two boxes. I’ve actually written a full post just on LADA if you want the deeper dive.
Myth: Diabetics can never eat sugar or candy
This one gets repeated so often it barely registers as a myth anymore, it just gets treated as common sense. It’s not. Managing diabetes is about the whole picture, not banning a single ingredient. Plenty of people with diabetes eat sweets and plan around it. The blanket “no sugar, ever” version makes for an easy plot point, but it’s not how it actually works.
Myth: There’s a universal list of “bad” foods
This is the one I most wish people understood, because it’s so individual. Some people can eat something like white rice and manage it fine with insulin. In our house, my husband mostly skips it, not because he can’t handle it, but because managing the math and timing around it is more hassle than it’s worth to him. Someone else might make the opposite call, and it would be just as correct. There’s no universal forbidden list. There’s just what works for that person’s body and life.
Why it matters
Most people’s only real exposure to what diabetes looks like day to day comes from a screenwriter’s version of it, not the actual thing. That gap shapes how people react in real emergencies, what they assume about someone’s choices at a birthday party, and what they think they already know before anyone explains it. The truth is a lot less dramatic than the movies make it look, and honestly, that’s kind of the point.
