I am non- insulin diabetic. I take pills not insulin to control my diabetes. I recently asked my physician if it is safe for me to fast. He said yes. But... He instructed that I needed to take my blood sugar in the morning. Depending on the reading, I may or may not have to take my medication. Then I am to check my blood sugar again at normal lunch time. And again at night before "dinner".
Because we fast on bread, this is carbohydrates which turn into sugar in your blood. There will be spikes of higher blood sugar. If you don't eat enough bread, you risk developing hypoglycemia or too low blood sugar. I need to plan when I am going to take bread. I drink water through the day.
I have not had any lows in blood sugar when fasting, bit if I did, I would take a glucose tablet. I typically fast from midnight Thursday until 10 or 11 PM on Friday. Then I have something to eat that contains protein.
I find it very easy to fast. Also, because I am retired, I can decrease my hunger by "living softly". That means placing less demand for calories, which contols hunger.
Always consult your physician first! For me, he said it was safe.
God Bless You in Your Life and Fasting
