Ileus at Altitude.

Abstract

Autoimmune myasthenia gravis (MG) is a condition commonly caused by the production of antibodies that block acetylcholine receptors. Until recently, gastrointestinal (GI) symptoms were considered rare in myasthenia gravis, but are now being proposed as an early identification tool. Presented here is a case study that exemplifies GI symptoms in MG, exacerbated by low barometric pressure at altitude. This illustrates the need to identify GI symptoms earlier in MG patients, as well as the need for providers at high altitude to be aware of these manifestations of MG.
