Asthma is an inflammatory, chronic condition that affects more than 300 million people worldwide. It is vital to understand how lifestyle factors like dietary patterns, gut health, and stress affect asthma severity to manage the disease effectively. Still, there is limited evidence for these associations, especially in urban settings like Mumbai, India. This research explored the association between dietary intake, gut health, and stress score with asthma severity in adults aged 18 to 45 years diagnosed with asthma. Forty participants were recruited by convenience sampling. Asthma severity was measured by the Asthma Control Test (ACT), and dietary intake was determined through a 24-hour dietary recall and Food Frequency Questionnaire (FFQ). Gut health was quantified with the Gastrointestinal Health Questionnaire, and stress with the Perceived Stress Scale (PSS). The results showed a significant positive correlation between certain food groups and asthma severity. In addition, higher perceived stress scores were significantly associated with worse asthma control. While gut-related symptoms were commonly reported, there was a Negative statistical correlation between gut health and asthma severity
