Hello guys! greetings from Brazil.
I guess this is my first post.
I have diabetes (T1) for the last 17 years and currently I am on a pump and have been using Dexcom as well.
Always had good control and could manage my weight pretty well…
2 years ago I did a check-up and found that my TSH was high - the doc started with levothyroxine 25mcg/day.
After 3 weeks he increase the dose to 50mcg. At that point my bgs started to climb… It was very hard to keep the BG under control. I had to adjust the basal in 30-40% and my carb/insulin ratio changed as well.
After living some months like that and injecting 40-50% more insulin, as expected, I started to gain weight.
For weeks, I would run every day, eat a minimum amount of carbs / calories and still would not loose weight.
I talked again to the doctor and she decided to prescribe metformin.
After taking Metformin my life became way easier. I could reduce the basal even lower than pre-levo days.
Now I can control my weight in a good manner again.
I have read in so many places the interactions between levo and insulin/ bgs. Most of the people says that levo does not affect their BG or in some cases it affects BGs while you are not in the right dose.
My dose keeps going up (today I am on 100mcg) and my TSH around 4.
Can you please share you experience? I would like to eventually stop taking Metformin, but today I cannot do that at the expense of gaining a lot of weight.
