Could inefficient breathing be contributing to symptoms?

Updated: 2 days ago

Following on from my last blog on medically unexplained symptoms (click here if you have not read this blog) I hope the summary below helps health professionals and patients consider whether inefficient (dysfunctional) breathing could be causing the patient’s symptoms or contributing to their symptoms or medical problems.

A 2019 paper states 1 in 10 adults in primary care in the United Kingdom breathe inefficiently and in individuals with asthma one third of women and a fifth of men do not breathe efficiently. Personally I believe rates are much higher now due to increased rates of stress and mask wearing during the pandemic encouraging a mouth breathing habit.

Although inefficient breathing has been investigated for decades, it remains poorly understood because of a lack of high-quality research and an absence of a gold standard to diagnose this condition. Inefficient breathing is often underdiagnosed or misdiagnosed as symptoms are similar to other conditions (e.g. asthma) or sometimes the symptoms are labelled as a form of anxiety.

Below are a list of features that if present increase the likelihood of inefficient breathing. The more features that are present the higher the likelihood of inefficient breathing. I have also included aspects that are more common in sleep disordered breathing because if an individual has sleep disordered breathing they are breathing inefficiently whilst sleeping. This is not a document to diagnose inefficient breathing instead my aim is to help the health professional or patient consider whether inefficient breathing is a possibility. There are many other causes for the signs and symptoms listed below which the health professional will need to consider, manage and potentially investigate.

I have combined this list from the sources listed at the end of my blog in addition to my clinical experience as a Functional Breathing Practitioner & GP. I am also grateful to Dr Joanne Ingleby (Dentist with interest in sleep disordered breathing who delivers bespoke Mandibular Advancement Devices) & Fiona Schreuder (Cardiorespiratory physiotherapist for their input using their clinical experience into this article.

Vomiting, burping, bloating, constipation, diarrhoea, excess wind.


Feeling weak, exhaustion, sweating, night sweats, waking from sleep to pass urine.

Repeat medication list

Respiratory tract

Nasal sprays, inhalers – especially if overused and patients feel they are ineffective, antihistamines.

Mental Health

Opiates, baclofen, gabapentin.


High fluoride toothpaste.


Laxatives, IBS medication, proton pump inhibitors (e.g. omeprazole or lansoprazole), antacids.


Medication with risk of weight gain. As the length of the list increases the risk of inefficient breathing increases.

‘Having had several years of suffering a variety of symptoms (pins & needles all limbs and left side of face, weight loss, gut issues) that basically was making my life pretty miserable, and having had many  doctor/hospital appointments for a wide selection of tests with no diagnosis made I had given up hope and started to put up with the situation thinking there was no help available. When it got to a stage where I was only getting 3 hours sleep a night I was exhausted and could not carry on, I decided to go back to the doctors. Thankfully I saw Dr Oliver who suggested it may help me if I took part in a breathing exercise seminar as the problems I was having could be connected by me not breathing correctly. Initially I thought how bizarre what a strange thing to suggest but was so desperate I was happy to try anything so accepted her offer of a free place. Well what can I say, by doing the seminar it became very apparent that I definitely had a problem with my breathing (my comfortable breath hold time was only 3.5 seconds) even though I didn't feel breathless. I followed the exercises given which were easy to do and within a very short time my symptoms started to ease and eventually ceased, I was having between 6 and 8 hours quality sleep a night, that in itself was fantastic. I cannot thank Dr Oliver enough for her recommendations’

'I have tried many apps and read many books in an attempt to improve my sleep pattern to no avail, but this course cracked it!  I am now sleeping fully through the night which has been a life changer for me. Everyday living, work, emotions & general well-being become so much easier to manage, more positive & happier with sleep. I generally feel calmer and am more in tune with my stress levels through changes in my breathing. I have learnt so much from this course and will be forever grateful. Thank you Louise'

'I am already sleeping better, feel more refreshed when I wake and have way more energy during the day. I feel in control of my sympathetic nervous system now rather than the other way round (which I believe has been the driver of my autoimmune thyroid problem). I am able to recognise much sooner when my sympathetic nervous system is triggered and using the breath-work am better able to switch this off'

My mission is to raise AWARENESS that how we breath matters, encouraging individuals to ASSESS their breathing efficiency & empowering individuals to take ACTION to improve their breathing efficiency.
