Gastrointestinal issues


Hello, doctor.
I have a few questions to ask you.
Recently, I went to the hospital due to abdominal pain and underwent an endoscopy, blood tests, and a fecal occult blood test.
The results showed that I have gastritis after the endoscopy, my blood tests were normal, and the doctor mentioned that there is inflammation indicated by the fecal occult blood test, but did not specify where the problem lies.
I was advised not to retain stool due to the gastritis and started taking medication for my stomach.
However, I have noticed a significant change in my bowel habits; I used to have a bowel movement once a day, but now it has increased to 2-3 times a day, and the amount has decreased to just one or two small stools each time.
The color of my stool is a light brown, and the shape is elongated but seems thinner than before.
Sometimes I feel the urge to have a bowel movement.
I'm uncertain whether this is a side effect of the stomach medication (I am taking VESYCA F.C.
TAB 150MG) or if it is caused by the gastritis, or perhaps due to recent changes in my diet, as I have been eating more vegetables than meat lately.
Should I consider getting a colonoscopy? What does it mean that there is inflammation indicated by the fecal occult blood test? Thank you very much.

Hello: Fecal occult blood primarily tests for the presence of blood in the stool and is not directly related to inflammation.
If there are changes in bowel habits, it is recommended to consult a gastroenterologist for evaluation.
Wishing you peace and health.
Sincerely, Dr.

When it comes to gastrointestinal issues, understanding when to consider a colonoscopy can be crucial for proper diagnosis and treatment. Based on your symptoms and the results of your recent tests, let's delve into your concerns.

Firstly, you mentioned experiencing abdominal pain, changes in bowel habits, and the presence of inflammation as indicated by your stool tests. The fact that you have been diagnosed with gastritis and are currently on medication (VESYCA F.C. TAB 150MG) suggests that your gastrointestinal tract is under some stress. VESYCA is primarily used to treat overactive bladder, but it can also have side effects that may affect your gastrointestinal function, such as constipation or changes in bowel habits.

The changes in your bowel habits—specifically, an increase in frequency to 2-3 times a day, a decrease in stool volume, and a change in stool shape—are noteworthy. While it is common for dietary changes, such as an increase in vegetable intake, to affect bowel movements, the persistence of these changes alongside your abdominal pain warrants further investigation.
The presence of inflammation in your stool tests indicates that there may be an underlying issue in your gastrointestinal tract, which could range from mild irritation to more significant conditions. Inflammation can be a sign of various gastrointestinal disorders, including infections, inflammatory bowel disease (IBD), or even functional disorders like irritable bowel syndrome (IBS).

Given your symptoms and the results of your tests, here are some considerations regarding whether you should undergo a colonoscopy:
1. Duration and Severity of Symptoms: If your symptoms persist or worsen, a colonoscopy may be warranted. This procedure can help visualize the colon and rectum, allowing for the identification of any abnormalities such as polyps, inflammation, or other pathologies.

2. Family History: If you have a family history of gastrointestinal diseases, particularly colorectal cancer or inflammatory bowel disease, this increases the importance of thorough screening.

3. Stool Changes: The changes in your stool, especially if they are accompanied by abdominal pain, could indicate a more serious condition that may not be visible through other tests. A colonoscopy can provide a direct view of the colon and help rule out significant issues.

4. Previous Test Results: Since your stool tests indicated inflammation, it is essential to follow up with your healthcare provider to discuss the implications of these results. They may recommend a colonoscopy to further investigate the source of inflammation.

5. Other Symptoms: If you experience additional symptoms such as weight loss, persistent abdominal pain, or blood in your stool, these would be strong indicators for a colonoscopy.

In summary, while dietary changes and medication can influence bowel habits, the combination of your symptoms and test results suggests that a colonoscopy could be beneficial for a comprehensive evaluation of your gastrointestinal health. It is essential to have a detailed discussion with your healthcare provider about your symptoms, test results, and any concerns you may have. They can provide personalized recommendations based on your medical history and current condition.
Remember, early detection and intervention are key in managing gastrointestinal issues effectively. If you feel uncertain or anxious about your symptoms, do not hesitate to seek further medical advice. Your health is paramount, and addressing these concerns proactively can lead to better outcomes.
