This report describes a frail 92-year-old woman with dementia who presented with a year’s history of chronic watery non-bloody diarrhoea. She had abdominal bloating, weight loss, faecal urgency, nocturnal stools and developed faecal incontinence. Her serum C reactive peptide and faecal calprotectin were elevated. Flexible sigmoidoscopy was macroscopically normal, but demonstrated histological features of microscopic colitis (MC) in sigmoid colon and rectal biopsies. Polypharmacy was reviewed for possible medication-induced MC. Ranitidine, donepezil and simvastatin were discontinued. She was started on oral budesonide with improvement in the abdominal and bowel symptoms. Stool frequency and consistency normalised, and the faecal incontinence resolved with treatment. The outcomes were an improved quality of life, reduced functional dependency, reduced carer strain and avoidance of premature transition from her home into a long-term/institutional care setting. We briefly review terminology, basic epidemiology, notable associations, the importance of establishing a diagnosis and some treatment considerations for MC.
