“…HG is associated with morbidity such as acute kidney injury (Machado et al, 2012), liver dysfunction (Shekhar et al, 2015), pneumomediastinum (Gorbach et al, 1997; Liang et al, 2002), ruptured esophagus (Buchanan et al, 2014), and Wernicke’s encephalopathy (Berdai et al, 2016; Giugale et al, 2015). In addition, a recent case-control study found that psychological distress was a direct consequence of HG (Aksoy et al, 2015), which is in accordance with previous reports of increased risk of cognitive, behavioral, and emotional disorders in this population (Poursharif et al, 2008; Zur, 2013). Even more, the complications associated with HG can result in termination of an otherwise wanted pregnancy (Poursharif et al, 2007; Trogstad et al, 2005).…”
