Snoring can double a person’s risk of developing gout, new research suggests.

A study of around 8,000 people suggests those who suffer from obstructive sleep apnoea (OSA) are more likely to develop the agonising joint condition.

Although gout is typically associated with heavy people who overindulge in alcohol and rich food, the UK study found that OSA patients with a healthy BMI are twice as likely to develop gout as those without the sleep disorder.

Sleep apnoea occurs when the muscles and soft tissue in the throat relax, blocking the airways. This restricts a person’s oxygen access, which is thought to drive the production of uric acid.

Excessive amounts of uric acid can turn into crystals that lead to severe inflammation and pain in the knees, ankles and feet, which is defined as gout. 

OSA affects between four and 10 per cent of people in the UK, while two per cent suffer from gout. In the US, around 22 million have sleep apnoea, while 8.3 million have the arthritic condition.

Gout is a form of arthritis that can be extremely painful. 

Agonising attacks come on very quickly, often during the night.

It affects around two per cent of people in the UK and 8.3 million in the US. 

Gout was once thought to be caused by overeating and drinking excessively, however, that is not the whole story.

The condition occurs due to a build up of uric acid, which can be because a person’s kidneys cannot get rid of the substance quickly enough. 

Over time, uric-acid crystals can form in and around the joints, which can trigger severe inflammation that usually settles within a week.

Around two-thirds of a person’s uric acid is already present in their body, while the remaining third comes from the break down of the chemical compounds purines in certain foods and drinks.

Foods and drinks high in purines include:

  • Alcohol
  • Red meat and offal
  • Oily fish, such as mackerel and salmon
  • Foods rich in yeast extract, like Marmite and Bovril 

As well as pain, symptoms can include joints being:

  • Red
  • Hot
  • Swollen
  • Shiny 

Without treatment, gout attacks can become more frequent, with more joints being affected.

The two most common painkillers used to treat gout are non-steroidal anti-inflammatory drugs, such as ibuprofen, and colchicine.

‘People with sleep apnoea are at an increased risk of gout’ 

The researchers, from Keele University, analysed 15,879 OSA patients and 63,296 healthy adults. The participants were followed for around six years.

Results, published in the journal Arthritis & Rheumatology, suggest that 4.9 per cent of the OSA patients developed gout compared to just 2.6 per cent of those without the sleep condition, making those with OSA 42 per cent more at risk.

Of the patients who went on to get gout, most were diagnosed with the arthritic condition between one and two years after developing OSA, however, it can take up to five years for symptoms to appear.

Lead author Dr Edward Roddy said: ‘People with sleep apnoea are at an increased risk of gout in both the short and long term.

‘Since this risk was highest in people with normal body mass index, doctors and other health professionals should consider the possibility of gout in patents with sleep apnoea – regardless of body mass index.’   

Sleep apnoea treatments could ease gout 

The researchers believe OSA treatment may also help to ease gout.  

Study author Dr Milica Blagojevic-Bucknall explained: ‘Sleep apnoea is commonly treated with continuous positive airways pressure (CPAP) therapy.

‘Since CPAP treatment corrects low oxygen levels it might also be expected to reduce uric acid levels, which could possibly reduce the risk of developing gout or treat existing gout.

‘However further research is needed to investigate the effect of treatment with CPAP in people with gout.’

CPAP therapy consists of a plastic mask that fits over the nose and mouth, and is connected to a machine that blows air under low pressure continually into the back of the throat as a patient lies in bed.

Missing teeth may cause OSA

This comes after research released earlier this month suggested people who look after their teeth are less likely to suffer from insomnia due to their risk of OSA being reduced.

Pensioners with less than 10 teeth often do not get the recommend seven hours of sleep a night, with some getting by on less than four hours, a study by Tohoku University, Japan, found.

Missing teeth are thought to affect how the tongue lies in the mouth, which may lead to OSA, according to the researchers.

The researchers, who were the first to investigate how teeth affects sleep in older people, wrote: ‘With the over-60s population set to reach two billion worldwide by 2050 perhaps it’s time we all paid a visit to the dentist.’ 


Obstructive sleep apnoea (OSA) occurs when the walls of a person’s throat relax and narrow during sleep, blocking their airways.

This interrupts normal breathing, with symptoms including loud snoring, noisy and laboured breathing, and repeated episodes when breathing is interrupted by gasping and snorting. 

OSA affects between four and 10 per cent of people in the UK. In the US, around 22 million are affected.

During an episode, the lack of oxygen triggers a sufferer’s brain to pull them out of deep sleep so their airways reopen.

These repeated sleep interruptions can make the person very tired, with them often being unaware of what the problem is.

Risks for OSA include:

  • Being overweight – excess body fat increases the bulk of soft tissues in the neck
  • Being male 
  • Being 40 or over
  • Having a large neck
  • Drinking excessive amounts of alcohol
  • Being in the menopause – hormonal changes cause the throat muscles to relax  

Treatment includes lifestyle changes, such as loosing weight, if necessary, and avoiding alcohol. 

In addition, continuous positive airway pressure (CPAP) devices prevent the airway closing by delivering a continuous supply of compressed air through a mask.

A mandibular advancement device (MAD) can also be used, which is like a gum-shield that holds the jaw and tongue forward to increase the space at the back of the throat.

Untreated, OSA increases a person’s risk of high blood pressure, stroke, heart attacks and type 2 diabetes.
