Birth defects associated with deficiency in bariatric surgery patients

The following cases are exactly what I was terrified of happening to my post weight loss surgery baby.  You must be on top of your own nutrition and supplementation post surgery, and take PRECAUTIONS in avoiding pregnancy too soon -- or if your body is already seriously compromised.  (Says the girl who did not.)

The January 2010 issue of SOARD reports on 2 cases of birth defect that appear to have resulted from severe maternal vitamin deficiency after malabsorptive bariatric surgery.

The first case was of a baby born at 33 weeks to a 27 year old mother 16 months post-op from a biliopancreatic diversion (BPD). The mother was deficient in vitamin A, D, K, protein, selenium and zinc. The infant was delivered prematurely with multiple defects including bone malformation, cleft palate, facial hypoplasia, and respiratory insufficiency. The baby died at 3 months of age.

The second case was of a full-term infant born to a 26 year old mother 11 months post-op from a roux-en-y gastric bypass. The infant was born with multiple defects of bone and cartilage as well as hearing loss which were attributed primarily to maternal vitamin K deficiency.

While most of the recent reports of pregnancy after weight loss surgery have been positive in terms of both fetal and maternal health, these cases should remind us that nutritional deficiency in pregnancy can lead to grave results.

Both of these patients had been counseled about waiting 18 months to 2 years before becoming pregnant, one even having signed a consent form prior to bariatric surgery. Because of the significant impact that massive weight loss can have on fertility, it is likely that more young, obese women will opt for bariatric surgery to not only improve their overall health, but also to assist with pregnancy. Clinicians and patients alike need to be made aware of the problems that can arise when women who are not adequately nourished become pregnant.
