I was diagnosed fairly early on because my mother was familiar with the symptoms thanks to her T2 diabetic father.
I was on insulin literally the day after I was diagnosed.
But… it was caught early enough that I only needed a couple of units. Two or three with meals, just to make sure I didn’t go too high. One of my classmates in the hospital’s teen diabetic training class said “You’re taking so little it’s almost a waste of insulin.” But the nurse in charge was quick to interject that my body needed it. Gradually, as my body’s remaining insulin production capacity was destroyed and I continued to grow and to develop some resistance to artificial insulin, my requirements increased. But I needed some right from the start.
Here’s the thing. Your body typically needs about 5% of the insulin it’s capable of producing. T1D is what happens when your body gradually destroys that capacity. It could take years before anyone notices because even when 75% of your beta islet cells are gone, you still have more than enough. Being sick (cold, flu, etc.), consuming a large amount of sugar, or other circumstances can increase your need. Double it to 10%, perhaps. So if you’re down to 7%, you can be diagnosed diabetic but need little to no insulin for a while, so long as you watch what you eat and maybe exercise regularly to help. But that “honeymoon period” isn’t going to last.
I don’t know what your situation is. If you have an endo, ask him.
If you’re not having symptoms (nausea, vomiting, headaches, “sugar rush” hyperactivity, shakiness, severe thirst, frequent urination, or any of a long list of other possible symptoms - you won’t get them all, but you’ll get at least a few), you’re probably okay for now? You can get a BG meter and check from time to time, maybe.
I’m not a doctor. I’m not qualified to give medical advice. Even if I was a doctor, it would be wildly irresponsible to try to diagnose and treat you based on a forum post and no examination or anything. I can only offer general advice.
So… If you’re type 1, I’m very surprised that you’re not on insulin more than 6 months after diagnosis. That seems very unusual. It is worth calling the endo’s office to ask about that. You don’t necessarily need a full appointment right now. Just call up the secretary and say that you’d like to know why you’re not on insulin, when you can expect to start, and when you should have your next follow-up visit. They’ll check with the doctor and should let you know.
