    I thought 1997 put an end to this nonsense https://www.bmj.com/content/314/7093/1501.1.full

    A £2m libel action brought against Channel 4 by a former consultant cardiologist at one of London's leading teaching hospitals collapsed last week after he admitted that errors in scientific papers coauthored by him appeared to be “more than an honest slip of the pen.”

    Dr Peter Nixon, a consultant at Charing Cross Hospital until his retirement six years ago, withdrew his action and agreed to pay £765520 in costs to Channel 4, which he claimed had branded him a charlatan, unfit to practise medicine.

    In a comprehensive climbdown, he also agreed to the disclosure of all documents in the case to the General Medical Council–unless he voluntarily retires from practice in the meantime–and not to take legal action if the allegations are repeated by Channel Four, the producer and journalist Duncan Campbell, or his production company.

    Dr Nixon, who claimed that hyperventilation could cause a range of illnesses, including many heart attacks, Gulf War syndrome, post traumatic stress disorder and premenstrual tension, sued Channel Four, Mr Campbell, and his company Investigation and Production (TV) Limited over the programme “Preying …

My breathing rate is normal. 'Fixing chronic hyperventilation syndrome' doesn't sound like the answer for whatever my problem is.

    One of Wessely's early papers didn't find any evidence for a primary role for hyperventilation.


    "There was no association between level of functional impairment and degree of hyperventilation. There is only a weak association between hyperventilation and chronic fatigue syndrome."

    This paper from like-minded colleagues came to a similar conclusion:


    "However, no significant differences between CFS patients with and CFS patients without hyperventilation were found on severity of fatigue, impairment, number of complaints, activity level, psychopathology, and depression. It is concluded that hyperventilation in CFS should probably be regarded as an epiphenomenon."
