Abdominal bloating and constipation?


Doctor, I have a question.
Recently, I went to see a doctor due to abdominal pain and changes in my bowel habits.
The doctor only performed an X-ray, which showed significant gas in my stomach and severe gas in the right side of my intestines, as well as fecal impaction in the rectum and slow gastrointestinal motility.
I was prescribed MGO, Gaster, and Mopride Gascon.
After taking the medication for a few days, my bowel movements increased significantly, but the stool consistency has been thin and soft, sometimes flat, or only slightly larger.
Is this normal, or could it be related to the medication? Could you please check the X-ray for any other abnormalities that may have been overlooked or if there are any signs of tumors? Thank you.

Hello, this X-ray shows a higher amount of fecal matter, but no other abnormalities are noted.
Regarding concerns about tumors, X-rays cannot detect them.
It is recommended to first perform a fecal occult blood test.
If the results are abnormal, a colonoscopy will be necessary to confirm the presence of any tumors.
If the occult blood test is normal, it indicates that it is simply constipation.
I suggest increasing physical activity, consuming more vegetables, and maintaining a regular routine to alleviate the symptoms.
Thank you for your inquiry.

More Info


Bloating and constipation are common gastrointestinal issues that can significantly affect a person's quality of life. Understanding their causes and treatments is essential for effective management.
Causes of Bloating and Constipation:
1. Dietary Factors: High intake of fiber, particularly from beans, lentils, and certain vegetables, can lead to bloating. Conversely, a low-fiber diet can cause constipation. Foods that are high in fat or sugar can also contribute to these conditions.

2. Dehydration: Insufficient fluid intake can lead to hard stools, making them difficult to pass and resulting in constipation. Dehydration can also exacerbate bloating.

3. Sedentary Lifestyle: Lack of physical activity can slow down the digestive system, leading to constipation. Regular movement helps stimulate bowel function.

4. Medications: Certain medications, including opioids, antacids containing aluminum, and some antidepressants, can cause constipation as a side effect. The medications you mentioned—Mgo (magnesium oxide), Gaster (a proton pump inhibitor), and Mopride (a prokinetic agent)—can influence bowel movements and gas production.

5. Underlying Health Conditions: Conditions such as irritable bowel syndrome (IBS), hypothyroidism, and gastrointestinal obstructions can lead to bloating and constipation.
6. Stress and Anxiety: Psychological factors can affect gut motility and lead to bloating and constipation.

Treatment Options:
1. Dietary Adjustments: Increasing fiber intake gradually can help alleviate constipation, but it’s essential to balance this with adequate hydration. Foods rich in fiber include fruits, vegetables, whole grains, and legumes.
2. Hydration: Drinking plenty of water is crucial. Aim for at least 8-10 glasses of water a day to help soften stools and promote regular bowel movements.

3. Physical Activity: Regular exercise can help stimulate bowel function. Even simple activities like walking can be beneficial.

4. Medications: Over-the-counter laxatives or stool softeners can be used for constipation. However, it’s important to consult with a healthcare provider before starting any new medication, especially if you are already taking prescribed medications.

5. Probiotics: These can help restore the natural balance of gut bacteria, which may improve digestion and reduce bloating.

6. Stress Management: Techniques such as mindfulness, yoga, or therapy can help manage stress, which may improve gastrointestinal symptoms.

Regarding your specific situation, it’s not uncommon for medications to alter bowel habits. The fact that your stools are soft and sometimes thin could be a result of the medications you are taking. It’s essential to monitor these changes and discuss them with your healthcare provider. They may recommend adjusting your medication or further investigating your gastrointestinal health.

If you are concerned about the possibility of a tumor or other abnormalities, it’s crucial to follow up with your doctor. They may suggest additional imaging studies or tests to rule out any serious conditions. Always communicate openly with your healthcare provider about your symptoms and any changes you experience, as this will help them provide the best care tailored to your needs.

In summary, bloating and constipation can stem from various causes, including dietary habits, medications, and underlying health conditions. Treatment typically involves lifestyle modifications, dietary changes, and sometimes medication adjustments. If symptoms persist or worsen, further evaluation by a healthcare professional is warranted to ensure there are no underlying issues that need to be addressed.
