New to the forum, so sorry if this has been discussed before - I frequently wake up to vomit in the middle of the night. No indication the day before that anything is wrong. I'm Type 2, age 67 and have blood sugar measurements between 5.0 and 10.0 normally so haven't needed to test ketones, but tested today anyway - was 1.2. This dropped to 0.1 about 6 hours later. Are Ketones to blame? Anyone else experiencing same - diabetic nurse was not very helpful. Thank you.
