4. Women Who Are Overweight
Women who are overweight are at an increased chance of this type of diabetes. The reason is simple. Your body is already experiencing problems keeping up your energy levels, because of the excess weight. When you are overweight, you have a higher metabolism and therefore, higher energy requirements to keep going.
There may be other factors as well. This excludes women who have just a little bit of excess weight. The benchmark for whether you fall into the high-risk group is a BMI of 30 or higher. If you have a BMI lower than 30, then you have the same risk of developing gestational diabetes as someone who is not overweight at all.
