Why am I always bloated? Understanding digestive distress and when to seek care
By Dr. Jennifer Phan, Medical Director, Hoag Irvine Advanced Endoscopy Center
Before you lift your fork to your mouth, you already feel that familiar sense of dread: Will this meal leave you uncomfortable again?
For many people, chronic bloating, nausea, or abdominal pressure can turn eating into a daily source of anxiety. While occasional bloating is common, persistent digestive symptoms are not something you have to simply live with. With the right evaluation, it is often possible to identify the underlying cause and find meaningful relief.
More than just “something you ate”
Bloating is frequently blamed on diet alone, but ongoing symptoms can reflect how the digestive system and nervous system work together. The coordinated movement of muscles and nerves helps move food through the stomach and intestines. When that process is disrupted, people may experience symptoms such as abdominal fullness, nausea, constipation, or discomfort after meals.
These conditions are part of a growing area of medicine known as neurogastroenterology and motility, which focuses on disorders of gut–brain interaction. Although these conditions are common, they are often misunderstood or underdiagnosed.
At Hoag’s Digestive Health Institute (DHI), specialists take a comprehensive approach to evaluating persistent digestive symptoms. By considering factors such as medical history, hormonal changes, lifestyle habits, and family background, physicians can develop a clearer picture of what may be contributing to a patient’s discomfort.
Possible causes of chronic bloating
Ongoing bloating and abdominal distension can have many underlying causes. Your physician may evaluate:
Food intolerances or sensitivities
Changes in gut bacteria
Hormonal influences
Digestive motility disorders
Inflammation or infection
Functional gastrointestinal conditions such as irritable bowel syndrome or gastroparesis
When organs such as the stomach, small intestine or colon become distended, advanced imaging and specialized testing may help identify the reason. Understanding the root cause is key to creating a treatment plan that is both targeted and effective.
The gut as the body’s “second brain”
We now recognize that the digestive system plays a powerful role in overall well-being. Sometimes referred to as the body’s “second brain,” the gut communicates constantly with the central nervous system. Disruptions in this connection can affect how food is tolerated, how quickly digestion occurs and how symptoms are perceived.
Care in neurogastroenterology often involves a multidisciplinary team that may include gastroenterologists, neurologists, dietitians and minimally invasive surgical specialists. DHI recently welcomed Dr. Linda Nguyen, an expert on diseases involving gut-brain communication. Alongside Dr. Catherine Ngo, Director of Motility, they have brought new and innovative testing designed to identify potential triggers of symptoms. Most recently, they became the first in Southern California to offer CellTolerance, a test that determines a patient’s food intolerances from a microscopic level. This collaborative approach allows patients to receive personalized care designed to improve both digestive function and quality of life.
Finding relief—and moving forward
If you regularly experience bloating, nausea, unexplained fullness or difficulty tolerating meals, it may be time to seek expert evaluation. These symptoms can be frustrating and sometimes isolating, but they are also treatable. With advances in diagnostic tools and emerging therapies, many patients can regain comfort and confidence and make bloating a thing of the past.
