Diaphragmatic hernias (DH) are known to complicate pregnancy and high mortality rates have been reported due to delay in surgical intervention. The reported mortality rates in presence of strangulation ranged from 22 to 80% and almost one third of the reported cases, did not have any symptoms. A literature review suggests that, out of 43 cases of DH diagnosed during pregnancy, only six cases of right-sided BH have been reported until 2020. Prolonged maternal malnutrition affects the intrauterine growth of the foetus and increases the morbidity and mortality of both the mother and foetus, leading to maternal weight loss, electrolyte imbalances, and vitamin deficiency. In the present case study, 21-year-old primigravida female with right-sided congenital BH was diagnosed during pregnancy, 7 days after the initial presentation of symptoms of acute obstruction. On exploration ischemic bowel was noted and it was associated with foetal loss.
