Ay, 108 is actually still okay, hindi ka dapat mag-alala too much! Normal fasting blood sugar is usually below 100, but if yan ang reading mo bago kumain, that's borderline lang and not alarming pa, a few of my mum friends have similar numbers and their doctors said it's fine. But since stress talaga ang nag-trigger sa anxiety mo about it, I'd really suggest checking with your doctor para ma-clarify exactly kung saan ka ba, kasi sometimes ang stress mismo nag-aaffect ng glucose levels natin, eh. Maraming factors talaga, kung kailan last kang kumain, workout mo, sleep, so better to get a proper assessment from your doctor nalang para ma-ease your mind, ate!
