Eh normal je, lah! Blood sugar naik sikit after dexa injection adalah expected sebab dexa adalah steroid, so memang boleh spike glucose level especially kalau ada diabetes or prediabetes. A few of my mum friends yang kena dexa for inflammation juga experience the same thing, takde lah yang panic sangat. Just monitor your readings la for a few days, and try to makan sikit lebih careful (less carbs, more protein and fibre) sampai it stabilises balik. Tapi kalau BSP terus naik for more than a few days or jadi very high, better check with your doctor just to make sure semua okay, especially if you're on diabetic medications.
