I am expecting to start menstruating today. When I went to bed, my blood sugar was around 160 mg/dl (8.9 mmol/L). I corrected, but woke up this morning with the same blood sugar. I thought it was strange that it didn't drop so I decided to check for ketones.
I was surprised that I tested for large ketones (>80 mg/dl).
I am on an insulin pump -- so I immediately changed my infusion set and gave a correction injection. Nothing appeared to be wrong with my infusion set. Now I'm trying to figure out why I might have such large ketones and not such high blood sugars.
Does anyone know whether starting menstruation can cause ketones?
