Case of a CKD patient

An 86-year-old female was admitted to the hospital for further assessment of daily vomiting episodes over two weeks. Her medical history was significant for gastroesophageal reflux, stage IV chronic kidney disease, stage IV chronic obstructive pulmonary disease, a prior cerebrovascular accident, hypertension treated with verapamil, hyperlipidemia, and iron deficiency anaemia. The patient's haemoglobin at admission was 7.2 g/dL, raising worries about increasing anaemia. At the time of admission, the patient denied experiencing any stomach pain or hematemesis but did mention occasionally having dark-coloured faeces while taking daily aspirin and an oral iron supplement. The patient had an upper endoscopy with video capsule implantation after receiving a blood transfusion of 1 unit of packed red blood cells due to a suspected gastrointestinal haemorrhage.
