Extremely high blood sugar levels can be dangerous, and they can cause lasting health complications. Remember: if you ever have blood sugar readings that remain high for more than 24 hours without coming down (and after an effort has been made to lower them), you need to be addressed by a doctor.
That being said, we've all had those days when we get a random high blood sugar reading and we are not sure what caused it…or we forget to give insulin, or we eat a delicious dessert without realizing how much sugar is actually in it.
For whatever reason, those out of the ordinary high blood sugar readings happen and need to be treated. No need to rush to the doctor for every high blood sugar reading though. There are some simple steps you can take to lower blood sugar fast.
