The management of constipation can be challenging because it is often considered self-correcting and not usually life-threatening. While these assumptions can be correct, constipation has the potential to be detrimental to the wellbeing of people affected, and long-term mismanagement of the condition can mask potential underlying causes. While nursing professionals in primary care are often aware of the available treatment options for constipation, there is limited evidence available to assist them in carrying out an appropriate clinical assessment on which to inform treatment choices. This paper will illuminate best clinical practice in primary care for the assessment of constipation, using history taking from the patient and inspection, palpation, percussion and auscultation of the abdominal area.
