Why Your Bloating Is Not Going Away? Gut Doctor Lists 7 Reasons

The persistent and annoying feeling of tight waistband post meals is a sensation many individuals experience frequently. Abdominal bloating emerged as one of the most common digestive issues often explained as feeling full, tight, or even swollen belly area. While it can be a temporary issue caused by diet, chronic bloating can indicate an underlying health issue that requires thorough check-up.

According to a report featured in Cleveland Clinic, “The most common cause of stomach pain and bloating is excess intestinal gas. If you get a bloated stomach after eating, it may be a digestive issue. It might be as simple as eating too much too fast, or you could have a food intolerance or other condition that causes gas and digestive contents to build up. Your menstrual cycle is another common cause of temporary bloating. Sometimes a bloated stomach can indicate a more serious medical condition.” ¹

There can be several causes of bloating that may include consumption of high-fibre and gas-causing foods, food intolerance, chronic constipation, swallowing excessive air, intake of carbonated beverages, irritable bowel syndrome or IBS, and small intestine bacterial overgrowth or SIBO.

One of the most overlooked causes of persistent bloating is how you eat, not just what you eat. Eating too quickly, not chewing food properly, or talking while eating can cause you to swallow excess air. This trapped air can lead to discomfort and a feeling of fullness. Irregular meal timings can also disrupt digestion, making bloating more frequent.

Recently, Dr. Saurabh Sethi, AIIMS-trained gastroenterologist and liver specialist, also educated at Harvard and Stanford, took to his Instagram account and highlighted 7 reasons your bloating is not going away. ²

7 Reasons Your Bloating Is Not Going Away

1. Carbonated Drinks: Dr Sethi said, “You’re literally drinking gas - more distension.” It is worth mentioning that carbonated drinks lead to bloating, gas, burping by releasing carbon dioxide or CO2 gas into the stomach. The trapped gas can cause abdominal discomfort especially for those with gastroesophageal reflux disease (GERD) or sensitive digestion. It is significant to bring down the intake of soda, sparkling water, and beer if you are keen to alleviate the symptoms.  

2. Helicobacter Pylori Infection: “Can live silently for years - inflammation, indigestion, bloating,” said the gut doctor. The infection commonly causes bloating. It has emerged as the leading cause of bloating. It can cause gastritis and stomach ulcers.

An individual may also experience symptoms like persistent bloated feeling, abdominal pain or discomfort, nausea, belching, and premature fullness after eating. The bacteria leads to inflammation in the stomach lining thus causing discomfort and bloating.

3. Mislabeled As Anxiety: He said, “Gut-brain axis is real - the gut often drives the symptoms.” Anxiety can lead to bloating as well. The brain and gut and closely connected through the nervous system. Anxiety frequently causes physical digestive symptoms such as bloating, gas, nausea, stomach discomfort or pain. It occurs because stress hormones often disrupt digestion, slow stomach emptying, or may enhance swallowed air.  

4. Lactose Intolerance: “Common, underdiagnosed - dairy = bloating, gas,” stated the gut doctor. Certain foods may not suit your digestive system. Lactose intolerance, gluten sensitivity, or difficulty digesting certain carbohydrates (like beans, onions, or cabbage) can cause gas and bloating. If you notice discomfort after specific meals, it may be helpful to track your diet and identify triggers.

It is ideal to bring down dairy intake, using dairy alternatives, or taking lactase enzyme supplements (like Lactaid) to manage symptoms.

5. Fructan intolerance: Dr Sethi said, “You blamed gluten - but wheat’s fermentable carbs may be the trigger.” Fructan intolerance is one of major causes of bloating, especially in people with Irritable Bowel Syndrome (IBS). When not properly or fully digested, fructans may ferment in large bowel leading to gas, abdominal pain, distension, and diarrhea. Key high-fructan triggers are wheat, garlic, onions, and inulin, among other.

6. Celiac Disease: “Often missed - chronic bloating, fatigue, nutrient issues,” added Dr Sethi. It is listed as one of the top causes of chronic bloating, abdominal discomfort, and gas. It often occurs due to inflammation in the small intestine after ingesting gluten. The digestive distress takes place because the immune response damages the intestinal lining thus making it hard to digest and absorb food adequately.  

7. Hypothyroidism: The last cause of bloating as per Dr Sethi is hypothyroidism that “Slows gut motility - persistent bloating + constipation.” It can trigger bloating mainly by slowing down metabolism and digestion that can cause gas build-up, constipation, and water retention. An underactive thyroid can cause food to move slowly via the digestive tract and leads to bacterial imbalances or SIBO. Regular workouts, diet adjustments, and optimizing thyroid hormones can help you manage symptoms.
