Pregnancy can be an extremely difficult situation for the obese women. On most occasions, the obese women are treated very much differently during pregnancy than a woman with normal body weight.
The doctor’s biggest concern in this situation is how much more weight gain he can allow to the pregnant obese woman. A woman with normal body weight is allowed to gain 25-35 pounds of weight during pregnancy. However, obese women are allowed to gain only 15-25 pounds when pregnant. To ensure that they don’t end up gaining more weight, pregnant obese women need to be extremely diligent regarding their fitness levels and nutrition. However, this does not indicate that they should follow a strict diet plan or exercise vigorously. What it means is that once diagnosed with pregnancy an obese 
woman must become extremely careful about the food types she is consuming and must try incorporating some physical activities into their daily life. This will help her in staving off extra fetal weight.
Obese women are extremely susceptible towards developing gestational diabetes. They should eat small meals at regular intervals for keeping their blood sugar levels under control and avoiding onset of gestational diabetes. Like a pregnant woman with normal body weight, an obese pregnant woman must also eat both for herself and her baby. Her diet must consist of plenty of vegetables, fruits, healthy protein and carbs, calcium rich food items and water. Eating the right kind of foods will ensure that weight gain during pregnancy does not exceed the suggested limit by the doctor.
You may or may not be obese when pregnant your doctor is unlikely to suggest you to begin a fitness program. Putting added stress on the body can cause harm to the developing fetus; this is truer for the pregnant obese women. However, pregnant women including those who are obese should take part in physical activities like swimming and walking for keeping their weight within acceptable and safe limits.
