Introduction: Absorption disorders concern a broad spectrum of conditions with multiple etiologies and clinical manifestations. This case demonstrates a rare adverse effect of olmesartan-medoxomil. This case report intends to draw attention to the need for therapeutic revision as a crucial point in the etiological study of malabsorption syndrome, as well as to name more frequent differential diagnoses. Case description: 60-year-old woman, with a history of hypertension diagnosed in 2013 and medicated with olmesartan since then. She presented with diarrhea for more than four weeks. As the etiological investigation began, she spontaneously improved, so it was left incomplete. About four months later, she presented with vomiting and weight loss, and the etiological investigation was inconclusive. After the antihypertensive was changed, the complaints disappeared completely. Comment: Malabsorption syndrome caused by olmesartan-medoxomil is a rare diagnosis, but can have serious consequences for the patient. It is recommended that in patients on olmesartan and who develop these symptoms, in the absence of another cause, the drug is discontinued.
