Persistent ‘hard-to-resolve’ anaemia is a common presentation for anyone participating routinely in sport and that can be at any level, not just among the professionals. From our lovely ladies who take up running or Crossfit in their middle-age, to our MIL (men in Lycra) and ‘weekend warriors’, they may love it but their haemoglobin and their iron doesn’t! Anaemia equals reduced oxygen carrying capacity, a concern for anyone interested in optimising their performance but equally relevant to patients just trying to manage their energy throughout the day. In this important episode we identify 4 different types of anaemia seen in patients as a result of exercise, incorrectly lumped together as ‘Athlete’s’ Anaemia. Each type is easy to recognise once you know how and effective treatment of each is remarkably different. This summary and the super handy clinical resource that accompanies it will help you and your patients absolutely outrun it, at last.
