Description

We herein report the case of a 39-year-old man with recurrent asthma exacerbations preceded by abdominal cramps with the urge to defecate. The patient had a history of near-fatal asthma associated with these gastrointestinal symptoms starting five years before his admission. He stated that, even when his daily asthma symptoms were under control, he suffered from attacks, especially when he had a strong urge to defecate. Although the contribution of increased parasympathetic tone to the onset of bronchospasms was likely, anticholinergics were not effective. Instead, the patient's symptoms successfully improved following the prophylactic use of laxatives, which might therefore be an appropriate therapeutic option for this type of asthma.<br>
