It has nothing to do with your body weight
Obesity is a factor which affects your risk of developing gestational diabetes, but not all obese women will develop this condition. Gestational diabetes is a condition which has more to do with your body's ability to process glucose than your body weight. Besides this, your body's sensitivity to insulin decreases during pregnancy.
You may not need insulin
Not all women with gestational diabetes need insulin. Instead, most of them may successfully achieve normal blood sugar levels with the help of a balanced diet and proper physical activity. Even if insulin is required, a small dose is enough. Larger doses can be painful for the mother. She can take 4 small doses of insulin in a day. Recent studies suggest that oral medications can also be beneficial for women with gestational diabetes.
You may not necessarily gain weight
Weight gain is likely to take place in women with gestational diabetes. But if you look after your blood sugar levels, this may not necessarily happen. Following a proper diet and engaging in low-impact physical activities can be quite helpful in keeping blood sugar levels under control. Women with gestational diabetes must eat foods which have a low-glycemic index.
