Hi abeybaby! We are volunteers with life experience in dealing with type 1 diabetes, not medical professionals, so any information you receive here should be verified with your healthcare team.
The dawn phenomenon refers to an unexplained, elevated bg reading, first thing in the morning that is commonly attributed to stress hormones. I do not have any knowledge of this occuring in type 2 diabetics. With type 1 diabetes, stress can play a major role in elevated bg's. My 18 year old daughter always ran high during exam week in high school!
I have heard, however, that with type 2, exercise and eating a healthy diet can really be advantageous. You could also benefit (we all could!) from avoiding simple carbohydrates (white flour products, white rice, white potatoes, white pasta & processed foods). They spike your blood sugar and make the pancreas work harder producing insulin to bring the level down to a normal range. Whole grains are the way to go as the fiber slows down the blood sugar rise. So, stick to eating right and exercising and keeping a tab on your bg's. Good luck to you!
