@kateia Your roller coaster numbers are probably more common than we know. I am not a doctor, but I have Diabetes 2 and know from researching and going to an endocrinologist that there is no "written in stone" answer for the up and down numbers. The person who can tell you about your numbers is your doctor. One of the problems with Diabetes 2 is that every person is different. What spikes my numbers may not phase someone else. There are just too many variables: age, activity, food, family history, other medical problems, and on and on for as many people as there are who have this disease. It is interesting to read what happens to other people, but it may not ever be the same for you. I tried an experiment on myself to eat the same exact food three days in a row and do the same things to see if the numbers would be the same, and guess what? They were different every day! My endo said there are just too many other variables; it's not just food or activity, but even the temperature and other meds are a part too. Many other things. So, I read the personal experiences but mind myself based on what my doctor tells me from tests for me. Have you asked your doctor about the numbers? That would be good to do to see what he/she says. As time consuming as it is, it's not just one food; it's the combo of what you eat that makes a difference also. Do you check your food numbers? Can you make an appointment to see your doctor and ask? He can help you understand the why better than anyone else. I'm in the same boat with you and would like to know if you see your doctor.
I'll check back with you.
