What Every Provider Should Know About Type 1 Diabetes
Procedures Can Be Pesky
People who wear insulin pumps and/or CGMs must remove them for MRI and certain other imaging procedures. In some cases — as with CGMs and the Omnipod insulin delivery device that can’t be put back on after removal — this necessitates advance planning to bring along replacement equipment for immediately after the procedure.
Diabetes devices can stay in place for other imaging studies, such as x-rays, most CT scans, ECGs, and ultrasounds. For heaven’s sake, don’t ask us to remove our devices if it isn’t totally necessary.
In general, surprises that affect blood sugar are a bad idea. I recently underwent a gastric emptying study. I knew the test would involve eating radioactive eggs, but I didn’t find out there’s also a jelly sandwich with two slices of white bread until the technician handed it to me and told me to eat it. I had to quickly give myself insulin, and of course my blood sugar spiked later. Had I been forewarned, I could have at least “pre-bolused” 15-20 minutes in advance to give the insulin more time to start working.
Another anecdote: Prior to a dental appointment that involved numbing my gums for an in-depth cleaning, my longtime dental hygienist told me “be sure to eat before you come.” I do appreciate her thinking of my diabetes. However, while that advice would have made sense long ago when treatment involved two daily insulin injections without dose adjustments, now it’s more complicated.
Today, when we eat foods containing carbohydrates, we typically take short-acting insulin, which can lead to hypoglycemia if the dose given exceeds the amount needed for the carbs, regardless of how much is eaten. Better to not eat at all (assuming the basal insulin dose is correct) or just eat protein. And for the provider, best to just tell the patient about the eating limitations and make sure they know how to handle them.
Duh, We Already Have Diabetes
I’ve heard of at least four instances in which pregnant women with type 1 diabetes have been ordered to undergo an oral glucose tolerance test to screen for gestational diabetes. In two cases, it was a “can you believe it?!” post on Facebook, with the women rightly refusing to take the test.
But in May 2024, a pregnant woman reported she actually drank the liquid, her blood sugar skyrocketed, she was vomiting, and she was in the midst of trying to bring her glucose level down with insulin on her own at home. She hadn’t objected to taking the test because “my ob.gyn. knows I have diabetes,” so she figured it was appropriate.
I don’t work in a healthcare setting, but here’s my guess: The ob.gyn. hadn’t actually ordered the test but had neglected to UN-order a routine test for a pregnant patient who already had diabetes and obviously should NOT be forced to drink a high-sugar liquid for no reason. If this is happening in pregnancies with type 1 diabetes, it most certainly could be as well for those with pre-existing type 2 diabetes. Clearly, something should be done to prevent this unnecessary and potentially harmful scenario.
In summary, I think I speak for everyone living with type 1 diabetes in saying that we would like to have confidence that healthcare providers in all settings can provide care for whatever brought us to them without adding to the daily burden we already carry. Let’s work together.
