Losing a significant amount of weight through bariatric surgery can be life-changing. Many women opt for procedures like gastric bypass or sleeve gastrectomy to improve their health and quality of life. An exciting next step for some is getting pregnant and starting a family.
If you've had weight loss surgery and are considering pregnancy, here's what you need to know:
Get the green light from your bariatric surgeon. They'll want to make sure you're at a stable weight and that any nutritional deficiencies have been corrected before you get pregnant. Most experts recommend waiting 12-18 months after surgery.
Take prescribed vitamins and supplements. Pregnancy places higher nutritional demands on your body, so work closely with your doctor to get the nutrients you and baby need. You could take an all-in-one prenatal vitamin. Common supplements include:
Achieve a healthy weight. Reaching your goal weight or close to it prior to conception can reduce risks to you and baby. Your doctor can advise you on an optimal weight range.
Address any fertility issues beforehand. Rapid weight loss can temporarily impact fertility, so consult your OB-GYN if you've been trying to conceive unsuccessfully. Consider seeing a reproductive endocrinologist for a fertility evaluation.
Focus on protein. Getting adequate protein is so important after bariatric surgery, and even more so during pregnancy. Aim for 60-80g daily by following a bariatric food diet, including foods like Greek yogurt, eggs, lean poultry, fish, tofu, beans, and protein shakes.
Stay hydrated. Dehydration is common post-surgery. Drink 64+ oz of fluids per day. Sip water constantly, and supplement with broth, protein shakes, diluted juice, and decaf tea. Avoid carbonation and straws.
Mind your portions. Small, frequent meals are key. Follow your surgeon's recommendations, usually 4-6 tiny meals per day. Use a small plate and take small bites. Go slowly and chew thoroughly. Check out this sample Bariatric Meal Plan guide.
Pick nutritious foods. Each bite must be packed with nutrition for you and baby. Focus on protein, fruits, vegetables, whole grains, dairy, nuts and healthy fats. Avoid empty calories.
Supplement as needed. Due to malabsorption, you'll likely need additional vitamins, minerals, and nutrients prescribed by your doctor. Common supplements include iron, calcium, vitamin B12, folic acid, and zinc, or choose a high quality bariatric multivitamin
Consider parenteral nutrition. If you cannot get adequate nutrition by mouth, IV feeding may be an option. Parenteral nutrition delivers nutrients directly into your bloodstream.
Prevent hyperemesis. Severe vomiting requires immediate treatment to avoid dehydration and hospitalization. Call your doctor right away if vomiting persists.
The keys are staying hydrated, getting enough protein, taking supplements as directed, and maintaining frequent contact with your healthcare team to manage nutritional needs safely.
Pregnancy after weight loss surgery presents some unique challenges and risks to monitor. Here are key issues to be aware of:
Nutritional deficiencies - Malabsorption after surgery heightens the risk for deficiencies in iron, folate, calcium, and vitamin B12 which are critical for maternal and fetal health. Closely monitor levels and supplement aggressively.
Nausea and vomiting - Morning sickness can be more severe and lead to dehydration. Sip fluids constantly, follow the post-surgery diet, and seek medications if vomiting is excessive.
Weight management - Adhere to recommended weight gain ranges for your BMI. Gain may be minimal in the first trimester. Follow up frequently with your bariatric team.
Dumping syndrome - Rapid food transit from pouch to intestine can worsen, causing diarrhea, nausea, cramping, and dizziness. Eat slowly, avoid sugars, and rest after meals.
Gastroschisis - Stomach surgery may increase the risk for this defect where the baby's intestines protrude outside the body through a hole beside the belly button. Discuss risks and monitoring with your OB.
Smaller stomach capacity - You'll need to eat smaller, more frequent meals with an emphasis on nutrient-dense calories. Work closely with your dietitian.
Birth defects - Risk may be slightly higher for some defects like neural tube defects. Take a higher dose prenatal vitamin with folic acid.
Gestational diabetes - Get screened early and follow up testing. Make nutrition adjustments as needed and monitor blood sugar levels.
Pregnancy after weight loss surgery can be a fulfilling journey. Remember, the steps you've taken to improve your health are already creating a brighter future for your child. While the path may have unique challenges, they can be successfully managed with the support of your healthcare team. Prioritize your mental and emotional well-being, and don't hesitate to seek help if you need it. In the postpartum period, adjust your nutritional intake according to your body's needs, particularly if you're breastfeeding. And above all, enjoy this special time. With careful planning and mindful living, you'll be cradling your bundle of joy in no time, starting a whole new chapter of joy and discovery.
