Hello, as you ve already noticed, body weight plays a very important role in blood glucose regulation. If you re overweight then loosing some Kilograms would help you reduce mean glucose values. Physical activity is a big part of diabetes treatment. It is as effective as a pill. You need to exercise daily for at least 30 minutes. You don t have to do intense exercise. Even walking a little faster than usual helps. Diet is very important as well. Avoiding food with high glycemic index and fat will help you achieve better glucose results. If you can t keep the blood sugar down to normal while being pregnant, you should receive treatment to avoid complications to the fetus. The most difficult time period comes after the 20th-24th week of pregnancy. Hormonal reasons make blood sugar regulation after that period more difficult than usual. I hope I ve helped! If you d like further information, please contact me again. Kind Regards!
