It's the question most often heard in monster movies. If not spoken aloud, you can bet comfortably that at least one character thought it. And if you think I'm referencing the title of those post, I'm not. I'm talking about, of course, diabetes. Don't scoff! Protagonists in monster movies are often thinking about diabetes. It's why they're willing to give their final convoluted plan a shot!
(Get it? "Give it a shot"? It is that I am being big jokester! Russian ancestors would be proud.)
Okay, okay. That's not a real thing. It'd be pretty amusing, though. Imagine Rick and Evelyn seeing the reanimated Imhotep for the first time in The Mummy (1999), and one asks in utter shock, "Is that... Is that DIABETES?!?" 🤣
The obvious thing I'm going to cover is the question, "What is diabetes." This is going to get technical in places, so I'm hoping to explain everything in a way that the average human can understand it. Most laymen only understand diabetes through some relative who has/had it, resulting in the generalized question, "You're not allowed sugar, right?"
(NOTE: Avoiding sugar is like avoiding air. It can't be done. But I'll get to that... someday.)
Complicating the question immediately is the fact that there are different types of diabetes. Allow me to go through them.
- Type 1 diabetes - Also known as juvenile diabetes or Type 1 DM for short. (The "DM" stands for "Diabetes Mellitus." I'll cover its name in a future post.) The patient is incapable of making any insulin whatsoever and must get it from an external source. For the record, you don't need to be a juvenile to be diagnosed with juvenile diabetes. I once met someone who was 27 when they were diagnosed with Type 1 DM.
- Type 2 diabetes - AKA adult onset diabetes or Type 2 DM. The patient with this version can't make enough insulin to cover the amount of food they eat, has become resistant to their own insulin, or their poor old pancreas just isn't making as much insulin as it had in its youth. This one can be controlled with diet and medication, although sometimes insulin injections are used to gain tighter control. (Having become a Type 2 DM to go along with my Type 1 DM, I did a deeper dive into Type 2... and I'm going to have to dive even deeper, since almost every source reads, "Obesity, obesity, obesity." But I'm not finding the answer to WHY obesity causes diabetes.)
- Gestational diabetes - Yes, ladies, you get your very own special version. You find yourself eating for two, but only making enough insulin for one. Women with this version of DM often have to take low doses of insulin. Up to 7% of all pregnancies can be complicated by this type, and there's always a chance of the diabetes becoming permanent.
- Prediabetes - I used to joke about this. "Prediabetes. It's like being 'pre-dead' or 'pre-pregnant.' It's silly. You are or you aren't!" But I've since learned more, and a person with prediabetes is someone who has all the markers to become a Type 2. This diagnosis is their big hint to make some serious lifestyle changes.
- Diabetes insipidus - I consider this one a kind of "false flag diabetes." It will mimic symptoms of diabetes mellitus, specifically polyuria (frequent urination) and polydipsia (extreme thirst). I'm only mentioning it because it exists, but it's not the kind of diabetes I'll be writing about.
As stated previously, I'm a Type 1 AND a Type 2. I'm not making ANY insulin and my body isn't processing the insulin that I DO take.
Since it's been mentioned so often, I'll explain insulin, its production, and its role in a person's metabolism. This will get VERY technical, but learning some of this will let your doctor know that you were paying attention at Diabetes School.
I used to think diabetes was about the body’s inability to break down sugar. Oh, how wrong I was! Insulin is a hormone that attaches to cells, allowing them to absorb sugar. Without insulin, the sugar stays in the bloodstream, causing all sorts of damage along the way. (Trust me. I'll get into the damage, probably in more detail than you'll ever want!)
There are areas of the pancreas called the islets of Langerhans. Those islets are where insulin is produced, stored, and released. Each islet has about 1000 to 2000 beta cells. Beta cells are primarily responsible for insulin production.
Other important regions of the islets of Langerhans are the alpha cells and delta cells. Alpha cells produce and release glucagon, which is used to raise blood sugar levels when they drop too low. Delta cells create somatostatin, a chemical that mediates on behalf of insulin by blocking glucagon. (For those familiar with the Greek alphabet, please don’t ask me where the "gamma cells" are. Someone somewhere skipped gamma altogether.) Finally, there are the PP cells that release pancreatic polypeptides to control all of the insulin, glucagon, and somatostatin activity.
A CORRECTION TO MY ORIGINAL MANUSCRIPT! I joked about the missing gamma cells, but it turns out that they're the "PP cells." Which brings about another complaint from me about diabetes education. There was so much commitment to use the Greek alphabet to list the various cells in the pancreas, but many of my sources skipped over "gamma cells" in favor of "PP cells." I'm starting to think they chose the latter for the sole purpose of being able to say "PP" in their scientific papers, and then giggle little children. ("Teehee! He said 'pee pee'.")
“How does all of this work together?” It’s like this... If you intake sugar, the regulatory parts of the brain tell the beta cells by way of the PP cells to release insulin. As the sugar gets broken down, the insulin attaches to various cells to allow the glucose (sugar) into those cells. Keep in mind that sugar is the major source of energy for EVERYTHING in the body, right on down to a microscopic level. If the cells inside your body can’t get their sugar fix, they will force other things in the body to become sources of energy. That’s bad. VERY bad!
It's a lot. I know it is. I'll admit that I don't have all this information memorized; I'm referring to my notes as I write this. So let me make it as simple as possible. If you eat a thing, and the thinking-thing tries to tell the other thing to make stuff so you can use the first thing, but the other thing is broken, you got diabetes.
Hmmm... Actually, that sounds like a few thousand other diseases. Let's try that again a little less generalized. If you eat something that can become sugar inside you, and the brain signals your pancreas to release insulin, but you have little or no insulin to release, then you're a diabetic.
Oh, I seem to have forgotten a detail about glucagon! Your pancreas makes this hormone when your blood sugar drops. It's the first line of defense against hypoglycemia, AKA low blood sugar. Too much insulin, too much physical activity, too little food intake, and your sugar levels can drop. Glucagon will signal sugar reserves throughout your body to be released.
If I ever get around to explaining The Somogyi Effect, you'll get a clearer view of what glucagon can do.
So that was lots of words to say, "You ain't got insulin? You got diabetes." But if you have any questions, feel free to ask me and I'll do what I can to answer. Yes, Google can probably answer your questions, but sometimes it's difficult to parse the information to find exactly what you want to know.
