Changes in Bowel Habits: When to Seek Medical Attention

Changes in bowel habits

I have always had a good bowel habit; after eating, I usually feel the urge to go to the bathroom without any abdominal pain, and it typically takes less than two minutes to finish.
However, during a trip abroad from late last year to January, my eating habits were not great.
I had fried chicken for several consecutive days upon waking up, and then I suddenly experienced vomiting and diarrhea.
I took two anti-diarrheal pills (though they seemed a bit expired).
After taking the medication, I suddenly stopped having bowel movements and have not felt the urge to go since then.
Recently, I noticed blood in my stool, and for about a week, I was only passing very small, pellet-like stools.
However, my recent bowel movements have returned to being shaped like logs, but they feel thin and somewhat like soft stools, as if I have mild diarrhea.
Even after wiping thoroughly, I still feel an itchiness around my anus, as if there is still stool at the anal opening, but I do not have any abdominal pain.
I would like to ask if this situation warrants a colonoscopy.

In this situation, you should see a doctor and avoid self-medicating with over-the-counter medications.
A colonoscopy may not be necessary, but it is important to have a physician evaluate and make a determination.

More Info

Changes in bowel habits can often be a source of concern, especially when they deviate from your normal patterns. In your case, it seems that you have experienced a significant change in your bowel habits following a trip abroad, where you encountered gastrointestinal distress characterized by vomiting and diarrhea. This was likely a response to dietary changes and possibly foodborne illness.
The symptoms you describe—such as the presence of blood in your stool, the change from regular bowel movements to small, pellet-like stools, and the sensation of incomplete evacuation—are important indicators that warrant medical attention. While the absence of abdominal pain might seem reassuring, it does not negate the need for further evaluation.
Blood in the stool can be caused by a variety of factors, ranging from benign conditions like hemorrhoids or anal fissures to more serious issues such as inflammatory bowel disease (IBD) or colorectal cancer. The fact that you have also experienced changes in the consistency and frequency of your bowel movements, along with the sensation of anal itching and incomplete evacuation, suggests that there may be an underlying issue that needs to be addressed.

Given your symptoms, it is advisable to seek medical attention promptly. A healthcare provider may recommend a thorough evaluation, which could include a physical examination, a review of your medical history, and possibly laboratory tests or imaging studies. A colonoscopy may be indicated, especially considering the presence of blood in your stool and the changes in your bowel habits. This procedure allows for direct visualization of the colon and rectum, enabling the physician to identify any abnormalities, take biopsies if necessary, and rule out serious conditions.

In addition to a colonoscopy, your doctor may also consider other diagnostic tests such as stool studies to check for infections or parasites, blood tests to assess for anemia or inflammation, and imaging studies if there are concerns about structural abnormalities.

It is also important to consider lifestyle factors that may contribute to your symptoms. Stress, dietary changes, and inadequate hydration can all impact bowel habits. After experiencing gastrointestinal distress, it may take some time for your digestive system to return to normal. Ensuring that you are consuming a balanced diet rich in fiber, staying well-hydrated, and managing stress through relaxation techniques can be beneficial.

In summary, while some changes in bowel habits can be benign, the combination of your symptoms—especially the presence of blood in your stool—indicates that you should seek medical attention. A healthcare professional will be able to provide a comprehensive evaluation and determine the appropriate course of action, which may include a colonoscopy and other diagnostic tests. Early intervention is key to addressing any potential issues and ensuring your overall health and well-being.
