Bowel Issues: When to Consider a Colonoscopy - Gastroenterology and Hepatology

Bowel movement difficulties


I have bowel movements almost every day and pass gas about 7 to 8 times daily.
However, after I finish a bowel movement, I often feel like I still need to have diarrhea (a sensation of incomplete evacuation), but this feeling goes away after resting or being busy.
Recently, I have been experiencing dull abdominal pain (similar to menstrual cramps, but not during my period).
There is no history of cancer in my family.
Should I consider getting a colonoscopy? (I have tested negative for occult blood).
I sincerely request your advice.
Thank you.

Dear Miss Lanlan,
Based on your description, it seems to be more like irritable bowel syndrome.
I recommend that you consult a gastroenterologist for evaluation.
If the treatment is not effective, it is also advisable to see a gynecologist and undergo a colonoscopy.

When it comes to bowel issues, particularly those that involve changes in bowel habits, discomfort, or unusual symptoms, it's essential to consider when to seek further evaluation, such as a colonoscopy. Based on your description, you experience daily bowel movements and excessive flatulence, but you also report a sensation of incomplete evacuation and recurrent abdominal discomfort.
The sensation of incomplete evacuation can be quite common and may not always indicate a serious underlying condition. It can be related to functional bowel disorders, such as irritable bowel syndrome (IBS), which is characterized by symptoms like abdominal pain, bloating, and changes in bowel habits without any identifiable structural abnormalities. However, the presence of persistent abdominal pain, especially if it is new or has changed in character, warrants further investigation.

Given that you have a negative occult blood test, which is a good sign as it suggests that there is no hidden bleeding in the gastrointestinal tract, it does reduce the immediate concern for serious conditions like colorectal cancer. However, it does not completely rule out other potential issues, such as inflammatory bowel disease (IBD), infections, or other gastrointestinal disorders.

Here are some factors to consider when deciding whether to pursue a colonoscopy:
1. Duration and Severity of Symptoms: If your symptoms have been persistent and are affecting your quality of life, it may be worth discussing a colonoscopy with your healthcare provider. Symptoms like recurrent abdominal pain, changes in bowel habits, or the sensation of incomplete evacuation that lasts for several weeks should be evaluated.

2. Associated Symptoms: If you experience additional symptoms such as weight loss, significant changes in appetite, fever, or blood in your stool, these are red flags that would necessitate further investigation.

3. Family History: While you mentioned there is no family history of cancer, it’s important to consider other gastrointestinal diseases that may run in families. If there are any other gastrointestinal issues in your family, it may influence the decision to have a colonoscopy.

4. Response to Treatment: If you have tried dietary changes, medications, or other interventions without relief, it may be time to consider a colonoscopy to rule out any underlying pathology.

5. Age and Risk Factors: Generally, routine screening for colorectal cancer begins at age 45 for average-risk individuals. If you are younger but have concerning symptoms, your doctor may recommend a colonoscopy regardless of age.

In conclusion, while your negative occult blood test is reassuring, the combination of your symptoms—especially the recurrent abdominal pain and sensation of incomplete evacuation—suggests that a conversation with your healthcare provider about the potential need for a colonoscopy is warranted. They can assess your symptoms in the context of your overall health and determine the best course of action. Remember, early detection and diagnosis are key in managing any gastrointestinal issues effectively.
