Nyctalopia during pregnancy due to vitamin A deficiency after bariatric sleeve gastrectomy: A case report.

KEY CLINICAL MESSAGE: Herein, we report a rare case of nyctalopia diagnosed in the first trimester of pregnancy due to vitamin A deficiency as a result of a bariatric gastrectomy. Low serum vitamin A levels establish the diagnosis and the patient was treated with oral vitamin A supplements. Moreover, due to the teratogenic effects of exceed Vitamin A levels in early pregnancy, supplements' dosages should be prescribed with respect to the safe limits. Our case aims to highlight the importance of checking micronutricients and vitamins levels before and during pregnancy in women that had a previous bariatric surgery.

ABSTRACT: Vitamin A deficiency (VAD) has been identified as the predominant factor in the development of night blindness during pregnancy, a high-risk for morbidity situation. Herein, we report a rare case of nyctalopia diagnosed in the first trimester of pregnancy due to VAD as a result of a bariatric gastrectomy. Our case aims to highlight the importance of checking micronutricients and vitamins levels before and during pregnancy in women that had a previous bariatric surgery. Low serum vitamin A levels establish the diagnosis and the patient was treated with oral vitamin A supplements. An uneventful antenatal course resulted in the birth of a healthy live neonatal at 38 weeks of gestation. In conclusion, nyctalopia is a rare condition in pregnant women that is often caused by VAD that poses significant health risks for both the mother and the infant, especially in women with a history of gastrointestinal bypass surgery, or any factors leading to malnutrition. Clinicians have to be alerted for micronutrients deficient in pregnant women who have a bariatric operation in their medical history.
