BLOATING, among other gas-related symptoms, has been linked to depression in a new study. Belching, trapped wind and bad breath could also be signs of poor mental health.
Gas-related symptoms were also associated with poor quality of life, higher stress and anxiety in the study conducted by scientists from the Rome Foundation Research Institute in the US in collaboration with Danone Nutricia Research in France. Nearly 6,000 people were surveyed across the United States, United Kingdom and Mexico.
The findings were based on a representative sample of people aged 18 to 99.
They were asked to fill out validated Intestinal Gas Questionnaires (IGQs)via the internet to measure the presence and severity of seven gas-related symptoms in the last 24 hours.
Researchers also collected information on body mass index, exercise, emotional wellbeing and quality of life in the past seven days.
Breaking wind was found to be the most frequently reported gas issue, affecting eight out of 10 adults.

Stomach rumbling affected 60.5 percent of respondents, closely followed by belching (58 percent) and bad breath (48.1 percent).
Trapped wind (47.2 percent), abdominal distension/swollen tummy (39.6 percent), and bloating/abdominal pressure (38.5 percent) also had a noticeable impact, while only 11.1 percent of respondents reported having no gas symptoms.
On average survey participants had been affected by three different gas symptoms within the previous 24-hour period.
The survey revealed higher IGQ scores correlated with lower mental health and quality of life scores on the PROMIS Global-10 questionnaire, higher stress, anxiety, and depression, and more non-gastrointestinal (GI) symptoms.
IGC scores did not correlate with weight/BMI and only had a modest negative association with the amount of exercise taken.
Younger people aged 18 to 34 and 35 to 49 had the highest overall burden of gas-related symptoms, with IGQ total scores of 24 and 22.6 respectively, compared to 12.7 in people aged 50 to 64 and 8.6 in the over 65s.
People in Mexico had higher scores for all seven gas symptoms in IGQ questionnaires, and a higher average IGQ total score, of 26 compared to 14.5 in the US and 13.7 in the UK.
Lead author, Professor Olafur Palsson from the University of North Carolina Department of Medicine, said: “I think the most remarkable and surprising finding in our study is that. “Brinkwire Summary News”.
