Bloating with a decrease in flatulence?


Dear Doctor,
I have been experiencing a dull sensation under my left rib cage recently, which sometimes extends to the left side of my lower back.
This has been ongoing for a week.
I consulted a traditional Chinese medicine practitioner who suggested it might be due to gas.
I also visited a gastroenterologist who performed an abdominal ultrasound.
Aside from the gas, everything appeared normal, but they noted inflammation in a certain area without specifying where.

Interestingly, regardless of the medications prescribed by either the traditional or Western medicine doctors, the discomfort seems to shift to my right lower back, where I feel a mild pain.
My bowel movements are still regular, occurring once a day, with no diarrhea or constipation, and the stool color is normal.
My appetite is generally the same, though I eat less due to the bloating.
There has been no change in my weight, and this is the first time I have experienced these symptoms.
I would like to ask: if I have gas, shouldn't it be easier to pass gas or burp? However, I am neither burping nor passing gas frequently, and the volume is significantly less, yet I still feel bloated.
What direction should I take to investigate the cause further? Thank you.

Hello, an abdominal ultrasound can generally rule out liver, gallbladder, and pancreatic diseases as the cause of pain after eating, which is more related to gastrointestinal issues.
Bloating is usually relieved by passing gas or burping.
The causes of bloating include poor dietary habits, eating too quickly, consuming gas-producing foods, gastrointestinal diseases (such as inflammation or ulcers), or functional gastrointestinal disorders like dyspepsia.
It is recommended to maintain a normal diet, chew food thoroughly, and avoid gas-producing foods (such as irritants and carbonated beverages).
If bloating and abdominal pain persist, it is advisable to seek medical attention and consider medication.
Wishing you good health.
Sincerely, Dr.

Bloating, especially when accompanied by reduced gas expulsion, can be a perplexing symptom that warrants careful evaluation. Your description of left-sided abdominal discomfort, the sensation of fullness, and the shift of discomfort to the right side after medication suggests a complex interplay of gastrointestinal issues.
Firstly, it’s important to understand that bloating can result from various causes, including dietary factors, gastrointestinal motility issues, and even stress. In your case, the fact that you have seen both traditional Chinese medicine practitioners and gastroenterologists indicates that you are already taking a comprehensive approach to your health. The ultrasound findings showing no significant abnormalities aside from gas accumulation suggest that there may not be any structural issues, but rather functional ones.

The sensation of bloating often correlates with the accumulation of gas in the intestines. Normally, when gas builds up, the body will expel it through belching or flatulence. However, if you are experiencing bloating without the typical gas expulsion, it could indicate a few potential issues:
1. Gut Motility Disorders: Conditions such as irritable bowel syndrome (IBS) can lead to altered gut motility, causing gas to become trapped and leading to bloating without the ability to pass it.
2. Dietary Factors: Certain foods can contribute to bloating and gas production. High-fiber foods, carbonated beverages, and certain carbohydrates (like beans, lentils, and some vegetables) can lead to increased gas production. Keeping a food diary may help identify any correlations between what you eat and your symptoms.

3. Dysbiosis: An imbalance in gut bacteria can also lead to bloating. Probiotics may help restore a healthy balance of gut flora, potentially alleviating symptoms.

4. Inflammation: You mentioned that there may be some inflammation, although it was not specified where. Inflammation in the gastrointestinal tract can lead to discomfort and bloating. Conditions such as gastritis or colitis could be considered, and further investigation may be warranted.

Given that your symptoms have persisted for a week and have changed in nature, it would be prudent to follow up with your healthcare provider. Here are some next steps you might consider:
- Further Testing: If the discomfort continues or worsens, additional tests such as a CT scan or endoscopy may be necessary to rule out any underlying conditions that were not visible on the ultrasound.

- Dietary Modifications: Consider working with a dietitian to identify any potential food intolerances or sensitivities. A low-FODMAP diet, which reduces certain fermentable carbohydrates, may be beneficial for some individuals with bloating.

- Hydration and Fiber: Ensure you are adequately hydrated and consuming enough soluble fiber, which can help with gut motility. However, be cautious with increasing fiber too quickly, as this can initially exacerbate bloating.

- Stress Management: Since stress can impact gut health, incorporating relaxation techniques such as yoga, meditation, or deep breathing exercises may help alleviate some symptoms.

- Probiotics: Discuss with your doctor the possibility of trying probiotics, which may help restore a healthy gut microbiome and improve symptoms of bloating.

In conclusion, while bloating can be uncomfortable and frustrating, understanding its potential causes can help guide you toward effective management strategies. It’s essential to maintain open communication with your healthcare providers and advocate for further evaluation if your symptoms persist or worsen.
