The mainstay of treatment of patients with severe restrictive eating disorders is initiation of nutrition to gain weight. One potential complication when patients are started on nutrition is the development of a massively enlarged stomach, also called acute gastric dilatation. If a patient’s care provider does not recognize the development of acute gastric dilatation, it can lead to serious problems, including death. Patients with this condition usually have abdominal pain, nausea, and vomiting. These are common symptoms in patients with anorexia nervosa and are often dismissed. Identifying risk factors associated with developing acute gastric dilatation could help providers recognize this condition and promptly start treatment. This study sought to identify risk factors associated with developing acute gastric dilatation in patients with severe restrictive eating disorders. Several variables, including patient age, duration of illness, body mass index, %ideal body weight, laboratory values, medications, type of nutrition, and rate of weight gain were analyzed. This study found that there are no specific risk factors significantly associated with development of acute gastric dilatation in patients with severe restrictive eating disorders being initiated on nutrition. Therefore, providers need to listen to their patients, evaluate symptoms, and have a high index of suspicion for underlying acute gastric dilatation.
