Her past medical history includes chronic lower back pain for which she takes regular co-codamol. The last time she was in hospital was for her cesarean section 10 years ago.
Upon examination, she appears clammy and dehydrated. Her abdomen is distended and tender throughout. Bowel sounds are inaudible.
