Fasting Blood Sugar 2.5 mmol/L (UK) after 1st day of Fasting

(Ruby) #1

Does anyone know if this is OK? I can’t find any reference to it. I don’t take any drugs, so that is not the reason. I feel fine. I don’t see what harm there can be. I think it’s good, if not a little scary.

I seems very low - keel over in a hypoglycemic coma low… do you not have the shakes, feel faint, etc. It’s equivalent to a US 45 mg/dl. Normal is 70-100.

Did you self test or at a doctor? If the latter, they would have probably put IV glucose into you. If the former, you may have contaminated the test strip or they have expired. If you are not feeling bad, then the reading is probably wrong.

Thank you for your reply Rob. A few hours later it went down to 2.4, so I broke my fast and it soon went up to 3.7, still a bit low, but I will eat again today. I was hoping to do a long fast, but I guess I will have to take it more slowly and build up.

Things went very wrong this morning, my dog pulled me over and I landed on my head in the road, this may not have happened if I hadn’t had such a low BS. We live and learn :slight_smile:

I didn’t see a doctor, I self test at home, I wasn’t noticeably shaking, but I suppose I wasn’t at my best.

Thank you again for taking the time to reply. Upwards and Onwards!

Without obvious symptoms (unruly dogs excepted), you might want to get some new strips just to see if there is an issue with them. In expired or even near expired ones, the reagent chemicals break down or it could be a bad batch? The strips could all be reading low? Anyway, I glad that you aren’t fighting a diabetic coma!

I’ve heard (and correct me if I’m wrong) that if your ketones are very high, a low reading isn’t a big deal. I’ve had mine read in the high 40’s and low 50’s, but with ketones over 3.0. I felt fine, so I didn’t worry.

Thank you Yayhowfun, my Ketones were very high (ketonix breath test, different measurements, 57), but I think I didn’t really feel that fine. I’m so keen to fast, but I think I’d better build up slowly. Meanwhile I’ll just have to suffer eating delicious fatty meals :wink:

ME too! thanks Rob.
