Hello Asri,
As you may know, we're volunteers and not medical professionals here.
Great work on your part to change things so you get your blood sugar into normal ranges. This is a challenge for many and you're doing great. Keeping your BG in normal ranges will help you heal faster from any infections and cna help you stave off devastating complications that can come from years of uncontrolled blood sugar.
Those of us who learn about the disease and how to manage it & keep our blood sugar in reasonably good control can expect to live long & healthy lives with it. Many diabetics have had this disease for 40, 50, 60 or more years ... being diagnosed long before we understood as much as we do now. I do understand the fear & worry about complications - especially since this is a new diagnosis. To ease your concerns, however, remind yourself that you ARE doing what IS needed to minimize those risks.
Many folks with Type 2 can maintain good blood sugar control by losing weight (as you have done), adjsuting their food choices (as you have done) and changing other things in their lifestyle (as you have done). Some folks can do all those things and still require medication -- either oral meds or insulin. Needing meds is NOT a condemnation of a person's efforts -- it's simply a requirement that your body needs more help than lifestyle changes alone can provide. You may never need meds or you may need them. As long as you do your part, you can reasonably think of meds as a supplement to that.
You can also expect that during periods of illness, injury, stress or infection, your blood sugar may rise.
A healthy diabetic lifestyle is, quite frankly, no different from a healthy lifestyle for everyone. We just have more motivation, I suppose, to make those good choices & maintain those changes ...
I'm assuming that you were diagnosed with Type 2 diabetes.
You should focus on happiness and laughter. Worrying is like a rocking chair . . .it gives you something to do but it will never get you anywhere. Keep a positive outlook on life and you should be fine. I have been diabetic for 21 yrs now. I was diagnosed at 3 yrs old. If you worry and stress about your health all the time then you will possibly miss what is important in your life, friends, family, and loved ones. Get your doctor to test you for diabetes. Face the challenge . . . Life is good!
