Obese women are also at increased risks for C-section deliveries, premature births and even pregnancy loss. [12]
  • Many pregnant women suffer from gestational diabetes. Gestational diabetes is diabetes during pregnancy in women who didn’t have this condition before they got pregnant. Now, gestational diabetes carries a lot of health risks to the baby. Your newborn can have excess birth weight, respiratory distress syndrome and other health issues. Women who are obese are at risk of gestational diabetes. But even this can be managed through diet and exercise and without weight loss drugs. [13]

Managing Weight During Pregnancy

So, now you know that drugs like phentermine are not the answer to maintain weight during pregnancy. So what can you do to keep to a healthy weight throughout your pregnancy?

You can take a number of measures for healthy weight gain during your pregnancy. [18]

  • Ask your doctor about week-by-week weight gain that is healthy for you. Your ideal number may differ from another pregnant woman. So, follow your own doctor’s recommendations as your weight gain will depend on several factors such as your health and your weight before pregnancy. You will also gain more if you are carrying twins or multiple babies.
  • If you are obese when pregnant, your doctor may ask you to follow a strict diet of healthy fruits, vegetables, low-fat dairy products and whole grains along with moderate exercises. You will also need to avoid processed foods and sweetened drinks.

Not all medicines are harmful to use during pregnancy. But use medications during pregnancy only when your doctor approves of it. And, know that taking phentermine when pregnant is absolutely unsafe. [19]

So, plan your pregnancy only after you have stopped using phentermine. And if you get pregnant while using it, stop immediately and inform your doctor about it.
