Upper abdominal pain and abdominal bloating?


Hello Doctor: Over the past year, I have frequently experienced a feeling of bloating in my stomach.
Sometimes the bloating subsides after passing gas or burping, but at other times it becomes quite uncomfortable and causes some pain in my stomach.
Most of the bloating occurs after 9 PM and lasts until I wake up the next morning.
Upon waking, I often find myself passing gas repeatedly, and only after using the restroom does the discomfort improve.
Occasionally, the bloating starts around 4 or 5 PM and continues until the next morning, which disrupts my sleep and causes me to wake up due to abdominal discomfort.
I have seen a doctor and underwent an endoscopy, during which the doctor noted mild inflammation in my stomach.
The doctor prescribed Nexium and Gas-X 40 mg.
When I was taking the medication, my condition was quite normal, but after a while, feeling better, I decided to stop the medication.
About one to two weeks after stopping, the symptoms returned.
I would like to ask the doctor what might be causing these symptoms? Additionally, what dietary precautions should I take? I am concerned that this could be a precursor to ulcers or cancer.

Walking after meals can improve peristalsis and reduce bloating.
It is advisable to limit the intake of gas-producing foods; bloating is generally not associated with cancer.

More Info


Upper abdominal pain and bloating can be quite distressing and may arise from various underlying causes. Based on your description, it seems that you have been experiencing bloating and discomfort primarily in the evening, which improves after passing gas or having a bowel movement. This pattern, along with your previous diagnosis of mild gastritis, suggests that your symptoms may be related to dietary habits, digestive issues, or even stress.


Possible Causes
1. Gastritis: As you mentioned, your doctor diagnosed you with mild gastritis. This condition involves inflammation of the stomach lining, which can lead to symptoms such as bloating, discomfort, and pain. Gastritis can be exacerbated by certain foods, alcohol, and stress.

2. Dietary Factors: Foods that are high in fat, spicy, or acidic can irritate the stomach lining and contribute to bloating. Additionally, carbonated beverages can introduce gas into the digestive system, leading to discomfort. Foods that are known to cause gas, such as beans, lentils, broccoli, and dairy products, may also be culprits.

3. Functional Dyspepsia: This is a common condition that causes symptoms of indigestion, including bloating and discomfort, without any identifiable organic cause. It can be triggered by stress, anxiety, or certain eating habits.

4. Irritable Bowel Syndrome (IBS): IBS can cause bloating, gas, and abdominal pain. It is often associated with changes in bowel habits, such as diarrhea or constipation. Stress and certain foods can trigger symptoms.

5. Peptic Ulcers: While your concern about ulcers and cancer is understandable, it is important to note that ulcers typically present with more severe pain, especially when the stomach is empty. However, if you have a family history of gastrointestinal issues or if your symptoms worsen, further evaluation may be warranted.


Dietary Tips
To manage your symptoms and reduce bloating, consider the following dietary recommendations:
1. Eat Smaller, More Frequent Meals: Instead of three large meals, try eating smaller portions throughout the day. This can help reduce the burden on your digestive system.

2. Avoid Trigger Foods: Keep a food diary to identify any specific foods that may exacerbate your symptoms. Common triggers include spicy foods, fatty foods, caffeine, alcohol, and dairy products.

3. Stay Hydrated: Drink plenty of water throughout the day, but try to avoid drinking large amounts during meals, as this can contribute to bloating.

4. Limit Carbonated Beverages: These can introduce gas into your digestive system, leading to increased bloating.

5. Incorporate Fiber Gradually: While fiber is essential for digestive health, increasing your intake too quickly can lead to gas and bloating. Gradually incorporate fiber-rich foods like fruits, vegetables, and whole grains.

6. Consider Probiotics: Probiotics can help balance gut bacteria and improve digestion. You can find them in yogurt, kefir, and supplements.

7. Mindful Eating: Eat slowly and chew your food thoroughly. This can help reduce the amount of air you swallow and improve digestion.


When to Seek Further Evaluation
If your symptoms persist despite dietary changes and medication, or if you experience severe pain, weight loss, or changes in bowel habits, it is essential to follow up with your healthcare provider. They may recommend further testing, such as an upper endoscopy or imaging studies, to rule out more serious conditions.

In conclusion, while your symptoms may be related to gastritis or dietary habits, it is crucial to monitor your condition and make necessary lifestyle adjustments. If you have ongoing concerns about ulcers or cancer, discussing these fears with your doctor can provide reassurance and guide appropriate testing if needed.
