This chapter, written for undergraduate medical students and post-graduate doctors in training, presents information on how to manage faintness — a case which they are likely to encounter in the future in a general practice setting. It presents the case of a woman who pale and leaning as if feeling faint. She was delivered 6 weeks ago of a son, her fourth child. He was born at home, but the midwife had a difficult time, owing to a brisk and unexpected post-partum haemorrhage. Fortunately, the baby is quite unaffected by her faintness and is thriving: she is breastfeeding him. The chapter provides details of the patients' medical history and the key findings of clinical examination, together with initial investigation results data for evaluation, and helps them develop their skills of clinical reasoning. Key questions then prompt the student to evaluate the patient, and reach a decision regarding their condition and the possible treatment plan.
