For many women, achieving a healthy body weight is just one important life goal. Having a family (or adding to their existing family) is even more important. It’s natural for female patients to wonder how weight-loss surgery (WLS) might affect their chances at having a complication-free pregnancy and a healthy baby. Here are some answers to commonly asked questions:
Is It Safe to Get Pregnant After Bariatric Surgery?
In most cases, the answer is yes. However, you should wait at least two years (or until your surgeon gives you the all clear) before trying to conceive. This time allows you to:
- Let your body adjust to the changes in how eating and digestion occur
- Get any potential nutritional deficiencies sorted out
- Stabilize at a lower body weight that is accompanied by fewer health risks during pregnancy
- Exit the ketosis stage of weight loss that might be harmful to the growing fetus
- Become comfortable with the alteration in your appearance before it starts to change again in pregnancy
- Regain strength (dramatic weight loss after bariatric surgery is often accompanied by fatigue)
If you accidentally become pregnant while you are still in the rapid weight loss phase, you may need additional medical intervention to keep you and your baby safe. It is not known at this time whether procedures such as gastric bypass affect how the body absorbs oral contraceptives. If you are sexually active, you may wish to use a backup contraception method to reduce the risk of getting pregnant too soon after weight-loss surgery.
How Might My Fertility Change After WLS?
For some women with polycystic ovarian syndrome (PCOS), bariatric surgery may help hormone levels to normalize. As a result, they may face fewer challenges in conceiving. Women who have other obesity-related health conditions that are associated with lower fertility also tend to have a better chance at getting pregnant after surgically assisted weight loss. The increase in fertility is similar to what patients could attain with a similar amount of non-surgical weight loss. This potential boost in fertility is another reason to be extra careful with contraception unless you are trying to get pregnant.
Are Pregnancy Risks Lower After Bariatric Surgery?
In many cases, yes. Health conditions such as high blood pressure and Type 2 diabetes often resolve after weight-loss surgery. Women who had a high chance of developing these conditions due to obesity are at much lower risk after losing weight with WLS. You may have a better shot at avoiding complications such as gestational diabetes, hypertension and preeclampsia that can put you and your baby at risk. However, you may still be overweight even after losing a lot of your excess weight. It is important to be monitored throughout your
