Similarly, low levels of CO2 in the bloodstream affects lactic acid buffering. This is often present in individuals who have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), chronic fatigue or post-viral fatigue. Lactic acid is the byproduct of exercise and, usually, it is easily removed due to the bicarbonate buffering system. However, in patients with chronic hyperventilation syndrome, the bicarbonate buffer becomes depleted. Thus, they quickly develop a build up of lactic acid, resulting in muscle aches and pains. Patients who have chronic fatigue or post-viral fatigue should, therefore, be assessed for breathing pattern dysfunction with the aim to restore a good breathing pattern at rest.[3]

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 …

Hmm. I got a lactic acid monitor a while back and tested how much lactic acid was in my blood, before and after exercise. It was all normal; the increase in lactic acid cleared in a normal time. 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.

https://pubmed.ncbi.nlm.nih.gov/8140219/

"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:

https://pubmed.ncbi.nlm.nih.gov/9330236/

"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."​
