This blog post was originally published on Hugging the Cactus on February 25, 2019. I’m sharing it again today because when I initially started taking Metformin, I felt really alone because I didn’t know any other person with T1D who was also taking it. It is my hope that talking about my experience helps someone who might feel similarly or would like to hear from a fellow T1D what it was like to start Metformin. Read on for more…

You may have read the title to this post and said to yourself, “Met-WHAT?”

Metformin is the new medication I’ve started taking (along with my typical insulin) to help regulate my blood sugars.

Maybe you didn’t make it all the way to that second sentence; instead, maybe you just Googled Metformin to learn more about it. And you probably immediately got confused, because the Google search results explained that Metformin is a medication normally prescribed to people with type 2 diabetes. You know that I have type 1, though, so what gives? Why am I taking this new pill?

You see, for about a year or so, my endocrinologist has been gently encouraging me to try Metformin. She expressed concerns over the fact that I’ve had diabetes for more than 20 years, and in that span of time, I’ve had to take a lot of insulin. Like, an incalculable amount. And while that insulin helps to keep me alive, there’s also risks associated with it. Namely, she explained to me that there’s research that indicates that people with type 1 who rely on large amounts of insulin have a higher risk of developing cancer later in life.

Whoa. The “c” word. Something I never thought I’d hear during a doctor’s appointment. If you know me personally at all, then I’m sure it’s not hard to imagine that I pretty much shutdown at the mention of “cancer”. Almost immediately, I panicked and asked why she thought this research was worth mentioning. She said that it was part of her reasoning for wanting me to start Metformin. The idea is that it would make my insulin more effective, and ultimately decrease the amount of insulin I need each day. She went into a little more detail, mentioning that the only side effects tend to be nausea/upset stomach – and that’s when I stopped listening. I politely told her that I didn’t think Metformin was a wise option for me at that time, and later that day, when I took to Twitter to ask other T1Ds what they thought, I gained swift validation that I’d made the right decision: Other T1Ds with Metformin experience told me that the stomach issues they had when taking it were miserable and that they wouldn’t recommend giving it a try. Plus, I consulted with my T1D pharmacist aunt, and her opinions matched those of the other T1Ds on Twitter. So that was all I needed to hear to feel at peace with my choice to not take Metformin.

In fact, it was enough for me to turn my endocrinologist’s offer down during our next two or three appointments. I was relieved that she never pushed me to try it, but there was a small part of me that wondered whether I should give it more serious consideration. Maybe I should let her talk me into a little, rather than brushing it away and using fear as my excuse.

So we did talk about, during my most recent visit with her earlier this month. She gave me some more compelling reasons to consider taking it. Not only could I reduce my insulin intake, but it might also help me with some preexisting digestive issues I’ve had since childhood. When I asked her about the negative side effects on the stomach that I’d read about online, she told me that she would only prescribe me the “extended release” version of Metformin, which had a much lower (if any) chance of inducing nausea or any less…desirable gastrointestinal disorders.

This news definitely perked me up. We discussed a plan for introducing Metformin to my body: Start by taking one pill daily after dinner. Increase by one pill each week until I’m at four pills per day, the limit. At any point in time, I could message her with questions if I started to notice low blood sugars in the evening.

I felt reassured by this logical plan, as well as her explanations of the benefits of Metformin. So I bit the bullet and I’m in my first week of incorporating it into my post-dinner routine. I can’t say that I’ve noticed even the slightest difference, which isn’t a bad thing. I imagine that will change as my dosage increases.

I intend to blog about this new journey with Metformin; not just for the sake of keeping track of how it affects me, but to also help inform other T1Ds who may have been or may be in the same situation that I was. We’ll just have to see how it goes, but for now, rest assured that I’ll be honest in my writings about my Metformin experience. At this moment in time, I can’t help but feel hopeful that down the road, I’ll be glad I made this decision when I felt ready for it, as opposed to when I was fearful of it.
